Versatile machining with RoboMACH HA 

Industrial automation and robotics specialists Loop Technology has a talent for solving complex engineering problems. Alongside a growing reputation in composite automation, they specialise in robotic machining systems. The latest innovation is the RoboMACH HA, a product that provides a cost-effective alternative to a large-capacity machine tool. It is extremely versatile in its application and delivers a variety of machining and processing applications. 

RoboMACH HA is integrated with a six-axis robot to provide drilling, milling, cutting, and trimming. In its standard configuration, it is integrated with a FANUC M- 800iA/60 which allows for high accuracy when machining harder materials such as cured carbon fibre alongside softer materials such as wood, engineering foam, plastic, and sand casting. Ultimately, the robot selection will be based on the specific requirements of the customer. 

James Streatfeild, Project Engineer at Loop Technology explained: “We recognised an opportunity to make robotic machining more accessible with a solution that would suit many applications. Ultimately, we are focused on ensuring our customers stay ahead of the market with a flexible, affordable process.” 

RoboMACH HA has been designed with a modular focus to offer product options meaning each system can be optimised to meet the requirements of the end user. This includes scalable machine guarding to ensure personnel are protected as well as plinth and spindle options dependent on required machining volume. 

With automatic tool changing and the option of adding additional rotary axes, it provides a level of versatility and flexibility that appeals to manufacturers engaged in complex machining. The tooling rack option is compatible with long and heavy tools and has the option of a broken tool sensor and a pneumatic lid. Furthermore, it is available with a 7th-axis positioner with a 1500kg load rating.   

Loop Technology are the official reseller of Robotmaster in the UK and Ireland and RoboMACH HA leverages this software to reduce robot downtime by creating simple and complex robot trajectories.

Technical Sales Engineer, Adam White states: “Robotmaster is the leading offline simulation and programming software for conducting trimming and machining operations with robot arms. Its ability to cut days of manual teaching down to a matter of minutes grants the user optimum flexibility.”

Using a robot to deliver different machining processes is a great option to consider. Through adjusting robotic programming and the end-of-arm tooling, objects of any size and shape can be milled, whilst exact cuts and movements for high-quality products can be achieved. Furthermore, Loop Technology can provide drilling solutions for various materials including carbon fibre, aluminium, and titanium, using orbital drilling technology to reduce heat concentration, tool wear, and improve the finished quality. 

RoboMACH HA is designed with the goal of increasing efficiency and speed in advanced manufacturing such as when cutting automotive parts and aerospace tools. Customers of RoboMACH HA include Solidwool, who make sustainable composite material made with British wool and bio-resin and use it to create furniture, homewares, and interior design finishes. They used the system to trim the excess bio-resin during the manufacture of their chairs. The Architectural Association used RoboMACH, a different configuration of this system, to automate the milling of unique forked trees. 

Loop Technology have other products on the frontier of automation technology. FibreLINE is a complete automation system for composite pre-forming that delivers an exponential increase in production rate for aircraft wings, train carriages and wind turbines. Additionally, there is LoopCLEAN Auto, a next-generation robotic laser cleaning system.

Blueprint for success

As a privately owned company with an enviable reputation for expertise in developing and providing engineering solutions within particularly demanding environments, SFM Technology is a specialist in project management, design, manufacturing and precision engineering. One of the company’s core competencies is 3D printing of parts for the aerospace industry – MTD magazine find out more. 

Introducing the company and its technologies, Gary Wilson, the Technical Sales Manager for the 3D Printing division of Somerset-based SFM Technology says: “We have a range of facilities and the business ranging from design to manufacturing, painting and more. We are essentially a one-stop shop for a range of industries from aerospace to agricultural.”

Looking at how the company started its 3D printing journey, Gary says: “3D printing came about after a discussion with the Managing Director, we had a problem with a component for the helicopter manufacturer. Working with a helicopter manufacturer we came up with a solution that created a design for the helicopter that enabled us to do the parts in 3D.”

As the Managing Director of Emvio Engineering, George Konstantinidis adds: “We offer a variety of services to industry as well as 3D printers and machine tools. When you come from the traditional manufacturing point of view, you need a skilled machine operator, whether it’s a CAD/CAM programmer or a time-served machinist. 3D Printing takes away a lot of that skill because all you have to be good at is maybe CAD. In effect, you could have an apprentice who can run the machine unsupervised from day one. So, from a skills gap point of view, 3D printing can be slotted into any business.”

Looking at the benefits of 3D printing and why the company has adopted this route, Gary adds: “There are many benefits of the 3D printer and one is the ability to program the model within the machine and this allows you to repeat and repeat, over and over again. As long as you have the material, the machine will print through the week, 24/7. This cuts manufacturing time down quite considerably and it is the same print result every single time.”

Adding to this, George says: “Printing using the FDM (Fused Deposition Modelling) method is starting to be adopted in industries like the casting market where pattern making is a skill that is being eclipsed. This is also a case for the production of jigs and fixtures where it takes somebody a lot less time to design 3D printable fixtures, this includes soft jaws or CMM fixtures. We are also seeing it be applied to end-use components, even in the aerospace industry. And this is how SFM Technology has progressed.”

Alluding to why the company has specifically invested in the bigrep PRO machine from Emvio Engineering, Gary says: “It’s the size. At the time of purchase, we needed a machine that could cover over a metre cubed, which this machine has. So, this machine is ideal for the work we were preparing to do. It fitted the bill with regards to the material, the size and the machine price.”

Discussing the machine in more detail, George says: “The bigrep PRO machine is the top-of-the-range machine that the company produce and it is well positioned for companies that want rapid prototyping and also parts that can be used as end products within the automotive and aerospace industries. This machine has been designed from the ground up and moves away from the traditional way of building a 3D printer. The machine uses servo controls and motors with a Bosch Rexroth system, to get all the benefits of servo-driven kinematics in a 3D printer. This makes the machine significantly more accurate, faster and user-friendly. In terms of travel, the machine has upwards of 1m in the X, Y and Z-axis.”

In conclusion, Gary says: “Using the FDM process, our business has gone from strength to strength and our orders have increased significantly. I can see that in time, the metal 3D printing will come into the equation and eventually be the way forward.”

5-axis productivity flows at Rivercircle

As a manufacturer of purpose-built leak test machines, special purpose machines and multi-cavity mould tools, Rivercircle Ltd manufactures and appreciates high-quality machines. That is why the Peterborough company has invested in two AXILE G8 5-axis machining centres. Available from the Engineering Technology Group (ETG), Rivercircle installed its first AXILE G8 in 2021 with the second machine arriving in September last year. 

The company is also involved in toolmaking for the automotive, pharmaceutical and medical sectors to name a few. It is the machining of pre-hardened tool steel and larger components that brought the addition of the two AXILE G8 machining centres. 

Jonathan Theobalds from Rivercircle says: “We bought our first 5-axis machine about five years ago. We had 3-axis CNCs for years and had been to all the shows and looked rather enviously at 5-axis machines, but we couldn’t see one at a price point for us. Eventually we dived in with our first one and then almost surprising to us, 18 months later we introduced a second machine. We very quickly learnt that actually having a 5-axis machine doesn’t mean that you have to have 5-axis work on the machine all of the time.”

Discussing one of the big advantages of investing in the AXILE G8 machine from ETG, Jonathan says: “With a 5-axis machine you are not doing multiple setups, so if we can strap the billet to the machine once and do all the heavy-duty coring-out work and then use the same machine for the delicate finishing, there is a huge efficiency advantage for us there. When we selected our original 5-axis, this gantry construction was very important.”

The move from a previous manufacturer to the AXILE brand was down to capacity – as very few machines can match the versatility, flexibility and speed of the AXILE G8 whilst holding up to 1350kg on the bed. The smaller 5-axis machines have a capacity limit of 650kg. 

With the ability to hold 1350kg on the moving bed of the 5-axis AXILE G8, Jonathan adds: “As machine builders, we really how the AXILE machines are built. The Y-axis has twin spindles and twin drives, the tilting B-axis has a motor on each side – it’s not just driven from one side. This gives the machine excellent rigidity and accuracy. Furthermore, the AXILE has a powerful spindle with 20,000rpm and high pressure through spindle coolant. This allows both heavy-duty roughing and high-speed finish machining.

“The expertise starts with the design and procurement through to tool path programming and obviously machining then fitting and assembly. It is our job to invest in and utilise the best quality machines. This has led traditional mould making to evolve into precision prototyping of parts and having this 5-axis machine where we can do parts in a single set-up, has enabled us to get lead times down. Furthermore, it enables us to keep our high levels of precision and quality of toolmaking for those parts. That is the thing that impresses customers when they visit us.” 

Referring to the user-friendliness of the AXILE G8, Jonathan concludes: “We programme our machines off-line with Mastercam and then send the files to the machines. As a predominantly Heidenhain machine shop, the AXILE G8 is equipped with the latest Heidenhain TNC640 CNC system that provides familiarity for our team. The AXILE G8 is also equipped with the latest software that enables ETG to remotely access, assess and rectify any issues we may have with the machines. Additionally, Ian Deacon from ETG has been extremely supportive of any teething issues we have encountered. For the operator, the AXILE is fast and efficient and this can also be seen in the machine design. The ergonomic design of the loading doors give easy access to the work area for the operator as well as excellent clear vertical access for large parts that need to be hoist lifted into the machine. Even the tool loading system is horizontal, which makes tool changeovers much easier for staff. Overall, we are delighted with the AXILE machines and the service from ETG.”

Starrag packs a high-end HMC into a small footprint

To accommodate the diverse needs of the marketplace, Starrag Heckert has now introduced its new H Compact Series of horizontal machining centres. The benefits of horizontals can sometimes be overshadowed by the sizeable footprint of the machines in comparison to their vertical counterparts – with the H Compact Series, Starrag Heckert delivers the benefits of a horizontal with a compact footprint that will appeal to manufacturers. 

Looking at the merits of the new H Compact machines, Lee Scott from Starrag says: “The new machines are called ‘Compact’ as they have a very compact size. They are horizontal machines which denote the ‘H’ and they are fitted with a trunnion table with 5-axis capability that provides an impressive X-axis range. We can also incorporate a high-speed table on the machine for turning – this configuration gives us the ‘T’ range. In its basic guise, it is a twin pallet horizontal machining centre with a monobloc mineral cast material base that is very vibration-absorbent and also very stiff. The machine design is like a giant bathtub where all the chips fall straight out of the work area and take all of the heat with them. The column then sits on the base with linear rails and a direct measuring system across the whole of the machine that delivers exceptional accuracy and optimal cutting conditions.”

The machine column also has positive leveraged ratios that are credited to maximum guideway distances and also weight compensation that improves performance, accuracy and efficiency of the Y-axis that is driven by ball screws. Alluding to the pallet system on the new series, Lee says: “It’s a twin pallet machine and the surface of the pallets are ground, so the interfaces are perfect for the fixturing, whether it be on a trunnion or a standard B-axis. Outside of the machine, we then have the setup station. So, whilst the first pallet is working inside the machining area, the second pallet is either loaded by a robot, an FMS or an operator. After all, if the spindle isn’t cutting, the machine isn’t making any money.”

As you would expect from Starrag, the machine has a complete range of spindles available. This includes a 30,000rpm spindle offering for cutting aluminium, high-torque or geared spindles for machining titanium as well as quill spindles for extended reach – there is a spindle for every application. Referring to the tool magazines that feed the spindle, Lee says: “The tool magazines start with a single magazine, and we can also run a parallel system with up to a total of 450 tools on this machine frame. You also have to get rid of the chips. This machine can create huge volumes of aluminium swarf that have to go through the machine, here the machine frame design has been optimised to remove chips from the work area at high speed.”

Taking a closer look at the operator interface on the new H Compact Series, the machine incorporates the latest FANUC or Siemens CNC control unit. As Lee continues: “Operators love our system, it has a touchscreen and multi-screen facility that offers the perfect solution for all engineers that really want to get that maximum amount of data from the machines. The control system offers a variable screen layout with between 1 to 3 applications that allow a parallel display of information with context-sensitive user guidance through the colour/brightness of the control elements. Furthermore, the system offers easy integration of third-party applications and/or VPN technology.”

As an automation-friendly solution, the new H Compact Series caters for customers with a wide range of options and interfaces to present maximum flexibility. Together with systems partners like Fastems, Starrag can offer FPC and FPT modules as well as integration with robots, gantry loading cells and interlinking machines from a single source.

Fabricator rebalances business 

Twenty years ago, Gareth Davies started Burton-on-Trent company TAS Engineering as a steel, stainless steel and aluminium fabrication shop serving the food, pharmaceutical and automotive sectors, and industry in general with fire escapes, factory staircases and secondary steelwork. 

In 2014, he established a machine shop to add extra value to the products the company was shaping and welding. Today, there is a pair of 3-axis VMCs on-site and three CNC lathes, the latest of which is a second-hand Cincom L20 sliding-head turning centre from Citizen Machinery UK.

What prompted the purchase in October 2023 of this 20-year-old lathe, the company’s first sliding-head model, was a desire to turn more efficiently from bar up to 20mm diameter. A case in point is the ongoing production since 2020 of a 16mm diameter, 316 stainless magnet holder, which is welded to a small, laser-cut and bent plate for industrial switchgear. The turned component, of which 200 are required per month, was previously produced complete on one of two fixed-head, twin-spindle lathes in a 2.5-minute cycle.

Mr Davies had previous experience of programming and setting sliding-head lathes from 40 years ago working. The lathes were equipped with servo-driven cams and while the technology has moved on enormously over the decades, the underlying principle is still similar. It was apparent that the steel magnet holder could be produced faster on a modern Citizen L20 twin-spindle, sliding-head turning centre than on a fixed-head lathe due to the faster axis motions of the gang tool carriers compared with the turret movements on the latter. However, Mr Davies was surprised to find that the part could be machined more than three times faster on the Cincom, the cycle now taking just 48 seconds.

The sliding-head turning centre was installed and commissioned in October 2023. Four additional jobs had been won by the end of January. None of this new work has anything to do with the fabrication side of TAS Engineering’s business. One contract involved the production of 1,000-off brass parts for a customer in industrial gases, which ran 24/7 for one week. 

The other jobs were 70-off engine parts produced from steel bar in one hit rather than in two operations on a fixed-head lathe plus another on a mill; 3,000-off heritage railway carriage brass fixing pins; and another component for the industrial gases sector machined from 0.75-inch diameter CZ121.

Mr Davies commented: “Although all the parts are relatively simple, some tolerances are tight. The bore on one of the components for industrial gases has to be held to 0.05mm total and the engine shaft OD must be within 0.04mm. Despite the Cincom being 20 years old, provided we run it at sensible feeds and speeds we achieve this level of accuracy easily. Not only that, but we have confidence leaving the machine running unattended.”

He went on to mention that he was treated by all Citizen Machinery UK staff as though he were purchasing a new L20. “They went above and beyond what would normally be expected for the sale of a used machine and the delivery, commissioning and training were exemplary.” 

TAS Engineering is currently undergoing a metamorphosis whereby, while fabrications will continue to play a part in the business, in the future it will only be if they undergo prismatic machining or contain turned parts. Already this policy has seen the contribution of chip removal, mostly metal and but also plastic, in the factory rise from 10% to 90% of turnover. It is a progression that was accelerated by the Covid pandemic.

It is notable that, for the jobs completed so far, repayments on finance for a new Cincom would not have been viable. On the other hand, paying back only one-quarter of the amount puts TAS Engineering in a strong position to quote for work very competitively, especially if it is not especially complex. Moreover, small quantities are also practicable, provided that the machine can be set up quickly.

🎧- Quantum leap in accuracy

At the Röhm GmbH plant in Sontheim Germany, 750 employees manufacture technology-oriented solutions for the automotive industry, mechanical engineering and aerospace sectors in a 41,000sq/m facility. The parts in question are finished on Kellenberger Premium grinding machines.

The company’s portfolio fits perfectly with the existing business areas of Rothenberger Holding, which generates a sales volume of €1.3billion with over 100 operating companies, many of them in the machine tool sector. Applying an extensive restructuring project, an investment sum of several million Euros was made available, which flowed into new machinery and systems. The aim for the future was to produce Röhm‘s high-tech products with even better quality and at the same time more cost-effectively.

For division manager Alexander Scheitenberger and his 35 staff members, the investment came exactly at the right time. Scheitenberger‘s department manufactures tool clamping systems, 40% of which are customised special designs. A trained industrial mechanic, Scheitenberger has been with Röhm since 1990 and is very familiar with all machining processes and the Röhm portfolio, which includes drill chucks, centre punches, lathe chucks and vices, robot gripping technology, power chucks, clamping cylinders, mandrels and tool clamping systems. 

The parts were machined on a KEL-VARIA universal grinding machine with a centre width of 1m, which had been in use for 18 years. With spare parts for key components no longer available, making a replacement investment became unavoidable. Scheitenberger and head of production Erhard Bader agreed, that the new machine should again be a KELLENBERGER. “We have had a very good experience with the KEL-VARIA. The reliability, accuracy and process safety of the machine over the runtime were outstanding. In addition, the cooperation with KELLENBERGER has always been characterised by a high level of professionalism. Erich Ziegler, the KELLENBERGER area manager who is responsible for us, gave us excellent advice on the new procurement.” Since 2018, the KELLENBERGER product portfolio has offered two machine designs, which can meet the machining tasks at Röhm. The new KELLENBERGER 100 platform concept proved to be the best solution, especially as Swiss manufacturer Wenger had specially adapted automation to the machine.

The task assigned to the engineers in St. Gallen, Switzerland, regarding the KELLENBERGER 100 was to develop a platform on which different machine concepts could be realised with a strong customer orientation. The segment of high-performance, low-cost grinding machines within the group was integrated into the concept. The modular solution on a common platform and a new assembly concept to reduce throughput time enable cost-efficient production of the machine and thus a very good price/performance ratio. 

The KELLENBERGER 100 offers the widest range of standard configurations for a variety of grinding operations. The machine is available in centre widths of 1,000/600mm and a centre height of 200mm and is designed for part weights of up to 150kg. A higher drive power for the grinding wheel (11,5kW) ensures increased productivity, while the newly designed guide in the Z-axis brings greater profile accuracy. For higher accuracy in non-circular grinding, the C-axis is equipped with a direct drive. Röhm opted for a machine with a centre width of 1m.

The K100 has a compact, collision-free tandem grinding head with motor spindles. Ten grinding head variants are available for the optimised design of the machine concerning the machined parts. The reinforced casing allows the largest grinding wheel diameters for internal grinding up to 125mm. 

The user-friendly, ergonomic design of the KELLENBERGER 100 machine is complemented by intuitive operator guidance via touch screen interface. The machines are equipped with a state-of-the-art FANUC 31i CNC control with a 19” touch screen. Various ready-made software packages are included as standard or can be added as an option. They cover simple workpieces, complex workpieces in the shortest machining time, and complex contours and profiles.

Swiss automation specialist Wenger has custom-designed the loading solution WeFlex for chucks and shaft parts, especially for the K100. The WeFlex loader enables automated processing of shaft parts from Ø6 to 100mm with a length from 20 to 600mm with a maximum gripper diameter of 80mm with workpiece weights up to 5kg in alternating mode and 15kg in single part mode. Interchangeable gripper heads facilitate quick changeover between the shaft and chuck parts. In the stacking module, 8 pallet spaces of size 400 by 600mm are available. Inserts for shaft or chuck parts can be inserted in the pallet frames.

The machine is loaded via telescopic line gantry and an automatic hatch closes off the machine room during machining to ensure the thermal stability of the machine. Directly at the infeed, electricity and compressed air are recorded, which allows the energy consumption of the WeFlex to be recorded and visualised. To reduce energy consumption, the speed of the WeFlex is automatically adjusted to the cycle time of the processing machine. An image-guided setup wizard assists the operator when changing over to a new workpiece. Wenger Managing Director Michael Wenger supervised the initial commissioning, which was followed by training for the Röhm employees at KELLENBERGER. One week after machine commissioning, the 3-shift operation was resumed. “The reliability of the loader works is very high and we haven’t had any downtime so far,“ reports Alexander Scheitenberger. 

The service package also includes remote maintenance of the machine and minor service work is handled internally at Röhm. “A couple of our employees have undergone service training with a focus on the new machine, so they can carry out minor repairs themselves,“ says Scheitenberger. “There is no need to call the KELLENBERGER service team for a minor issue. But if you do need the service, it’s fast and reliable.”

The conclusions of Alexander Scheitenberger and his colleagues are very positive: “In terms of accuracy, the new machine has brought us a quantum leap. Today, we grind with an accuracy of 2 microns with process reliability. The surface quality of the machined tool clamp is so good that, with the same polishing times, the results are many times better, from Ra 0.3-0.4 microns to below Ra 0.1. Due to the larger grinding wheel and because the new machine is simply faster than the old one, we have a 25% increase in productivity. In addition, personnel costs are 30% lower as the automation ensures that one operator is sufficient for two machines.”

ironMIND – know your machine

With a skilled labour shortage and full order books, businesses need to rely on their technology. But how do manufacturers know if repairs or downtimes are imminent?  

To fulfil requirements for modern and efficient production, the NSH Group, with its machine tool brands NILES-SIMMONS, HEGENSCHEIDT-MFD, RASOMA and WEMA-Gauchau, has developed its new software and service tool ‘ironMIND’.

Predictive and production-adapted maintenance and repair planning is essential and ironMIND has modules that provide a detailed picture of the condition, mechanics, controls and peripherals of machines at all times. 

Monitoring is often interpreted differently. One way is to collect and analyse data. NSH goes further, monitoring operating resources, consumption, drive temperatures or control status, it also undertakes regular tests on axes to examine axes condition. For each axis test, one axis is subjected to a specific motion profile. Drive data is recorded during these defined motions and is followed with the structured evaluation of the data. How does potential damage manifest itself in the data? What parameters need to be calculated for condition-based evaluation? How to define the limits that characterise the condition? 

Answering these questions requires information about the parts installed, the control system, and the machine data set – in-depth knowledge that the manufacturer can provide. It also requires knowledge of the test results and experience in identifying damage. ironMIND supports users in performing condition-related data and tests themselves. This diagnosis can be made with regular automated test execution and successful condition-based maintenance.

Interdisciplinary benefits 

Condition monitoring requires interdisciplinary collaboration between different departments. By knowing the condition of the components, it is possible to detect and correct failures before they occur. This enables early procurement of spare parts and reduces downtime. Dynamic maintenance intervals can also reduce maintenance costs. For the operator, ironMIND results in faster troubleshooting and fault elimination. Knowing the condition of components and control settings enables consistent machining quality. The result is reduced scrap, energy savings and financial benefits. By keeping an eye on consumption, green management approaches can be improved. 

The machine operator can use ‘ironMIND – Monitoring’ on the control panel, supported by an intuitive app and multi-window technology. All other departments can use the ‘ironMIND – Cockpit’ to log into the web front end with access from any device.

Data security

Data needs to be stored securely. NSH uses ironMIND to avoid this hard-to-trace data traffic by storing all measurement and control data on the machine or the local company network. One of the basic principles of ironMIND is that you are always in full control of your data.

Using the ironMIND application does not require an additional IPC or sensors. The only thing that is required is access to the control data to run the test. ironMIND uses existing sensors to visualise information on the fill level, consumption and filter status of the media. However, it is also possible to integrate additional sensors. 

A common approach is to record as much information as possible with additional sensors. One of the most common stumbling blocks to successful condition monitoring is the high initial investment for implementation. This discourages potential users and makes implementation more difficult. With ironMIND, NSH is taking a completely different approach, utilising existing hardware. In addition, ironMIND is scalable with a low monthly usage fee model.

The NSH Group delivers customised machine tools worldwide, as a matter of principle, NSH adapts its solutions to the customers. The top priority in the development of ironMIND is to provide added value. For this reason, NSH has worked with pilot customers throughout ironMIND development to understand customers needs and develop a customer-oriented solution.

With the constantly evolving ironMIND system, customers can record and evaluate machines and estimate and perform necessary maintenance before potential failure occurs. The ironMIND system is practical, affordable and safe. It delivers value by maintaining machine tool performance and service life, increasing productivity and reducing costs.  

🎧- SME reorganises its entire production processes

As a Swiss SME that has thoroughly examined its production from a digital perspective, Sistag AG has recognised the potential of bits and bytes. The company has modernised its facility with a Flexible Manufacturing System (FMS) from Fastems and this approach is yielding interesting results with new experiences and ambitious plans.

The globally active Sistag AG, headquartered in Eschenbach in the Canton of Lucerne, manufactures isolation valves for a wide range of industries. This includes pulp and paper, food and beverage, wastewater treatment and biogas/chemical plants. “In addition, we specialise in knife gate valves, known under the brand name Wey Valve. These valves are used in the petrochemical, oil production, and mining industries. Our mechanical production here employs around 165 employees, producing approximately 25,000 to 30,000 knife gate valves annually,” says Manuel Schmidlin, Head of Manufacturing at Sistag.

Like many other Swiss SMEs, Sistag faces high manufacturing costs. Manuel Schmidlin notes: “Land is expensive and labour costs are high. Moreover, finding skilled workers for production is challenging, so we have increasingly focused on in-house training.” To economically produce and manufacture, machines at Sistag must run almost non-stop. “We also have the advantage of being particularly strong in the field of special valves. Due to the relatively high level of automation here at Sistag, we can also compete in terms of pricing,” adds Schmidlin.

The housings, a core component for knife gate valves, are manufactured on two horizontal machining centres. In 2005, the company invested in an FMS from Fastems, specifically a Multi-Level System (MLS), initially connected to an OKK HM 630. In 2010, the system was expanded to a total length of 35m, with a second OKK machine of the same type added.

In 2022, Sistag decided to modernise the MLS. Manuel Schmidlin explains: “The electronics were still running on 32 bits, and the system was essentially at ‘End of Life’ with no replacement parts available. During the upgrade to a 64-bit system, we conducted a complete retrofit, both in terms of controls and mechanics.” As Sistag has been pursuing a consistent digitisation strategy for about four years, the FMS was not only updated with the Manufacturing Management Software (MMS) from Fastems but also placed a significant focus on digitising the entire production facility.

According to Manuel Schmidlin, the company has primarily grown historically in its 60-year history. Sentences like ‘We’ve always done it this way’ has been heard by the production manager many times.

“Our projected business has significantly increased. When a customer orders valves today, it’s not three or four, but immediately 400 or 500. With our existing infrastructure, we were not able to plan such large orders efficiently from start to finish. We had great difficulty keeping our machine capacities and we had no overview of what was happening at what time and where the priorities were. Therefore, our goal was to control our entire production with MMS as a central MES (Manufacturing Execution System).”

‘The Terra Incognita’ of A Manufacturing Organisation

The MMS from Fastems provides all the prerequisites for this digitisation approach, as it is currently one of the most powerful solutions for planning, running and monitoring automated machining production. The MMS automatically plans production up to 96 hours in advance while considering all necessary resources, such as raw materials, NC programs and tools, including their tool life.

Manuel Schmidlin is fully aware that for consistently planned production, standalone machines, manual workstations and inspection stations must eventually be included in the whole digitisation process, in addition to the automated equipment. Not an easy task, as these areas are often still a ‘Terra Incognita’ in a usual manufacturing organisation. Nevertheless, this situation is set to change at Sistag with the implementation of a Fastems MES solution for non-automated equipment – Work Cell Operations (WCO).

Solid carbide tools – Powerful and efficient 

Every metal-cutting application requires an ever more complex machining process and an increasingly difficult choice of materials. However, without the right tools, you will quickly reach limits. Solid carbide tools prove their efficiency in such cases time and time again. Nevertheless, it is essential to use tools that are precisely adapted to the process, the material and the batch size. If you rely on a supplier who has extensive application experience, a wide range of products and provides expert advice, they will maximise the benefits and reduce costs.

The efficiency of solid carbide tools has long been proven. Their wear resistance and the consistent quality of machining results are impressive for producing large batches. This allows users to quickly achieve economic results. Nevertheless, production managers should not blindly rely on solid carbide tools in the hope of having a universal all-around tool. 

Once you select the right material with the right coating, the tool manufacturer then has a decisive impact on the quality of the tool. For example, a supplier must know exactly what grain and which grinding finish are the right ones to use with steel, hardened steel, cast material, aluminium, non-ferrous metals or exotic materials. Other factors to consider are whether the process requires roughing, finishing, dry or wet machining and so on.

With so many vital details, it quickly becomes obvious that there is no such thing as a universal all-around tool for all processes and materials. Trustworthy suppliers should therefore offer a wide range of products. Arno Werkzeuge from Ostfildern is a supplier that takes this complexity in production together with the plethora of possibilities very seriously. They have extensive knowledge of materials, numerous applications and enormous expertise. 

“Thanks to the relationships we have built up with our customers, we have amassed a large pool of application knowledge. This is why our expertise allows us to offer exactly the right solid carbide tools for a wide range of machining processes and materials,” says Product Manager Marco Staiger from Arno Werkzeuge. 

You realise this when you browse through the 400-page catalogue of solid carbide milling cutters, drills and thread-milling tools. As Staiger emphasises: “Our application consultants will help you select the right solid carbide tools quickly and competently.”

And of course, the range also includes tools for general applications that cover a specific universal range. For many users, the Arno-FP milling cutter is an ideal entry-level tool that covers a wide range of metal-cutting operations on steel, stainless steel and cast materials. The universal milling cutter made of powder metal HSS steel is TiAIN-coated, extremely tough and wear-resistant. This ensures a longer tool life and maximum cutting performance.

If the application is even more specialised, the consultants can fall back on a further nine special milling cutters which can be used to their full potential. For example, AFA milling cutters offer excellent results with soft cuts in aluminium alloys. When it comes to steel, cast iron and stainless steel, there is a group of three special high-performance tools. For exotic materials, there are two milling cutters available – the AFE and the AFJ. Finally, users will find the right milling cutters for high-speed machining and dry cutting in the top league of pre-hardened steels up to 55HRc and extremely hardened steels up to 70HRc.

Customers appreciate the diversity of the range of solid carbide tools from Arno Werkzeuge. Not only that. Many customers recognise they can achieve tight tolerances using fully ground, high-precision tools. They are also extremely sturdy and sharp. Here, Staiger says, “Our product range also has tools to machine very small workpieces or to cater for special requirements.”

🎧- Sound of Music 

Like the ‘Sound of Music’ that has won its place in movie folklore, the 2024 ‘Sound of Studer’ themed event that took place at the company’s Steffisburg headquarters has won its place in the hearts and minds of the 65 journalists from over 20 countries that attended. The annual Fritz Studer AG event is always packed with the latest innovations in grinding, an insight into the company’s ongoing evolution and an overview of the global trends in the manufacturing industry – and the February event once again lived up to its billing. By Rhys Williams

Located in the Swiss Alps, in a region more stunning than the backdrop to the legendary movie, the ‘Music Motion Meeting 2024’ kicked off with presentations from the management team and was followed by technical presentations on the latest innovations and an insight into what we can expect to see as we move through 2024. 

Studer CEO Jens Bleher kicked off proceedings with a presentation that discussed the company’s performance over the last 12 months, the market turbulence, new updates to the CORE interface, product enhancements and the pride in the success the Swiss manufacturer continues to enjoy with its success at the World Skills event. 

“Despite the challenging investment environment, we again increased our sales, especially in key markets like the USA and China. Asia was the largest single region followed by Central Europe and North America and consistent investments in product development and site infrastructure have paid off. We have turned our announcements into reality and improved our market position to strengthen ourselves for the future in the long term,” the Studer CEO announced. 

Studer once again won market share in many regions around the world, and it hit a new sales record in its Customer Care segment. Bleher took it as a positive sign for the 2024 fiscal year that the order situation developed exceptionally well towards the end of 2023. Whilst confident that order intake will continue in a positive direction, the CEO was particularly bullish about the expected performance in the second half of 2024 – a period when the manufacturer of cylindrical grinding machines will present new technologies. 

Although the development of incoming orders was weaker in individual markets, such as Germany, China and some Asian countries, other parts of the world saw positive results. At the 2023 event, Turkey and several Eastern European countries were the surprise performers. At this year’s event, Sandro Bottazzo, CSO at Studer said: “We achieved good results in many countries and even posted a new record order intake in some.” Some of the standout performers were announced as Spain, Austria and Holland, a welcome boost with the headwinds of global uncertainty and inflation faced by some of the manufacturing powerhouse nations. 

Looking at the industry by customer segments, a point that should be marked as a good barometer of worldwide manufacturing performance for MTDCNC readers was that the aerospace industry once again generated the largest increase in new orders. This industry has now overtaken the declining automotive industry for Studer. The ‘tool’ manufacturing segment remained below expectations with the largest individual segment for the second consecutive year being ‘precision engineering’. “I am very pleased that our grinding machines are so highly trusted by small and medium-sized enterprises, and that this segment remains strategically important for us,” explained Bottazzo. The ‘mechanical engineering’ and ‘mould & die’ segments also maintained their critically important positions. The increasing demand for precision cylindrical grinding machines in the semiconductor industry has been marked as very pleasing for Studer with Bottazzo confirming robust semiconductor growth in the Americas and Asia.

The performance of specific precision cylindrical grinding machines and maintaining a broad portfolio remained of particular importance in 2023. Incoming orders for CNC universal cylindrical grinding machines were reported as very solid. The machine with the highest sales volume was the S33, followed by the favoritCNC, the S31, the S41 and the favorit. “When it comes to internal cylindrical grinding machines, it was the third-best year for incoming orders in the company’s history for the S131,” said Bottazzo. Orders for the new S100 internal cylindrical grinding machine were also very pleasing and exceeded targets. Whilst 2023 sales volumes didn’t exceed the 2022 numbers that were reported as the company’s third-best year on record, the order value was almost on par. This was due to higher-value turnkey solutions and the Customer Care packages reaching record numbers.

Alluding to the Customer Care division, Bottazzo added: “Here we were able to set a sales record for the second consecutive year. This applies to all business areas from maintenance and service to spare parts and overhauls. Particularly pleasing was the development in Eastern Europe, where Studer now performs service with its skilled personnel in the Czech Republic, Slovakia, Poland, and Hungary.” This expansion and the incredible growth have lit the way for the company to continue investing in the Customer Care division. 

In 2023, Studer participated in more than 30 trade shows. At EMO 2023 the company presented three automation solutions for the first time. The arrival of the new insertLoad loader as well as the roboLoad and uniLoad was a paradigm shift for the company and these were prominent during the press tour of the facility. 

Throughout 2023, the focus remained on the development and advancement of grinding technologies. The S36 external cylindrical grinding machine introduced in May 2022 has proven particularly suitable for components in the e-mobility sector since its arrival. Alluding to this, CTO Daniel Huber added: “Now, our customers can use all spindle variants and automation solutions without restrictions on the S36. Thanks to the new, powerful grinding spindle with 25kW, it is possible to use particularly wide grinding wheels up to 160mm.” The S36 fills a gap between the existing S11 and S22 machines and it offers greater spindle and automation variants. This includes integration with the easyLoad and uniLoad systems that permit customers to automate production on the S36. Additional options include the ability to add high-speed grinding with CBN or diamond grinding wheels and the Smartjet system.

Huber also mentioned the success of the new S100 internal cylindrical grinding machine that was introduced in October 2022. Since this introduction, new spindle options have already been added such as the powerful Ø58mm dressing spindle with more additions planned for further models in the future.

As the company moves through 2024, sales are expected to remain strong with a projected upturn in the second half of the year. This will be set in motion by major exhibition appearances and the arrival of new models for the respective events. The new arrival will be a successor to the popular favoritCNC that will reveal new features. Some features in the pipeline include an angle display of the wheel head, the popular QuickSet setup function and a conventional mode as a manual grinding cycle that permits manual grinding without any programming.

A particular focus for development in 2023 was given to the company’s C.O.R.E. hardware and software architecture from the UNITED GRINDING GROUP. “The C.O.R.E. touch operating panel already allows an unprecedented level of intuitive use. Soon there will be a customisable interface where operators can define and save their workspace,” explained Huber. Data collection and analysis, as well as new sensors and instruments, were also a focus. 

Looking to the future of the business, the CTO added: “The issue of sustainability continues to be important. The SmartJet® cooling system developed by Studer already sets new industry standards with its ability to reduce the need for coolant and energy in the grinding process. Demand for high-performance semiconductors is also rising due to e-mobility and photovoltaics. Studer’s S41 CNC universal cylindrical grinding machine with in-situ X-ray measuring head now sets the standard in wafer manufacturing. It is extremely successful in the market. In the long term, only the machine manufacturers who offer intelligent and efficient machines incorporating the latest technology can be successful,” summarised the CTO as he reflected on the extensive development activities over the past 12 months.

Obviously, the success of a business is not purely based upon its product lines, but also its very foundations. To reflect upon the internal business activities, COO Stephan Stoll provided an overview, saying: “The production mix of the machines manufactured has shifted to more complex systems through 2023. With active procurement management and the normalisation of global supply chains, orders were completed on time.” Stoll positively assessed the implementation of the joint production strategy within the UNITED GRINDING Group, which provided Studer with significantly improved utilisation.

Major operational projects included investments in automated test stands and manufacturing tools. As one of the very few grinding manufacturers producing high-quality spindles, the expertise for these strategically important machine components has been expanded. Comprehensive structural and logistical measures were further implemented in Steffisburg. This has been bolstered in the internal grinding competence centre in Biel with plans for further growth. Referring to the additional growth, the COO said: “After the considerable investments of the past years, the redesign of our logistics processes and warehouse infrastructure is now imminent. The centrepiece of this project is a central logistics hub with a directly connected container warehouse. The higher efficiency of the fully automated warehouse system will benefit machine production.” 

The press was shown a roadmap of the planned changes to the manufacturing facility and how it will streamline production, service and logistics. In conclusion, Jens Bleher emphasised the great importance of well-trained employees. He was very pleased with the recent successes at the prestigious professional championships, SwissSkills. Last year, Studer apprentices Luis Salzmann (1st place, design engineer EFZ) and Noah Rossel (2nd place, automation engineer EFZ) won the gold and silver medals with their outstanding performances. “STUDER is represented for the third time in a row at the WorldSkills showcase. We are very proud of this. It confirms our extensive commitment to vocational training,” concludes CEO Bleher.

This commitment to education was further strengthened with an award presentation at the press event for its research prize, the ‘Fritz Studer Award’.  Applicants from several European countries submitted their work and it was Dr. Emil Sauter who won the award and the prize of CHF 10,000. The Fritz Studer Award is aimed at graduates from European universities and technical colleges. “The objectives of the research prize are to boost innovation in the machine tool industry with feasible solutions whilst also promoting young technical and scientific talents,” says Dr Frank Fiebelkorn, Head of Research and Technology at Studer. 

Numerous theses and dissertations were submitted to Studer and evaluated by a panel of experts consisting of Prof. Konrad Wegener, Inspire Institute for Machine Tools and Manufacturing at ETH Zurich, Dr Hans-Werner Hoffmeister, former head of the Manufacturing Technology department at the Institute for Machine Tools and Manufacturing Technology of the TU Braunschweig, and Dr Frank Fiebelkorn, Head of Research and Technology at Fritz Studer AG. Criteria for evaluating the works included the feasibility of the findings in the mechanical engineering industry, the degree of innovation and quality of the research idea, scientific content, form, and the accuracy of statements, and the results and findings. 

The Fritz Studer Award 2023 was presented to Dr. Emil Sauter from the Institute for Manufacturing Technology and Machine Tools at ETH Zurich. He impressed the entire jury with his topic. ‘Detection and avoidance of thermal damage for high-performance metal grinding processes using hybrid machine learning models.’

His work deals with the development of an innovative condition monitoring system for external cylindrical grinding with metal-bonded CBN tools, which recognises thermal damage in situ and predicts the remaining useful life of grinding tools with relative accuracy. Process parameters such as structure-borne noise, spindle current and force characteristics can be identified. With time-frequency transformations, the research identified features of a process to detect different stages of thermal damage. The remaining tool life can also be estimated. In general, this work with its many industry-oriented practical tests also shows that machine learning methods can lead to higher productivity and improved component quality. Whilst MTD magazine extends its congratulations to Dr Emil Sauter, we also applaud Studer for creating a platform for the engineers of tomorrow.

🎧- Guhring builds lifelong relationship based on results

LMS Precision Engineering has trusted its tooling supplier for over 35 years. With a relationship that dates back more than three decades, many manufacturers would ask ‘why?’ The simple answer lies in the fact that Midlands-based LMS works with Guhring UK, one the world’s leading manufacturers of cutting tools with UK manufacturing facilities and expert engineers on hand to deliver optimal machining solutions, whatever the challenge.

Scott Street, a partner at Droitwich-based LMS Precision Engineering says: “We are a family-run business that has been operating for over 40 years. Our main sectors of interest are aerospace and general subcontract machining. We have always had a great relationship with Guhring.”

Discussing the relationship, Chris Bush from Guhring says: “LMS and Guhring have been working together for over 35 years now. LMS use the whole spectrum of our cutting tools, whether that’s milling cutters, drills, taps or thread mills. In fact, everything through to the Tool Management vending machine. LMS were one of the first customers to see the advantages of a tool management vending machine. Allowing them to put their resources in providing components rather than manually ordering tools, looking for tools and managing tool stocks. The TM machine automated all this and much more. The relationship has evolved so much over the years. In that period, cutting tool technology has changed and evolved hugely, as has the LMS business, the technology it invests in and the size of the company. The customer base at LMS has evolved as well, and they are machining a lot of different materials, so down the 35-year relationship – it has been exponential growth and change on both sides. However one thing remains, and that is the strength of our partnership.”

The Guhring Tool Management vending solutions can be built to a customer’s requirements and are available in open drawer type for maximum versatility or 100% secure single tool dispensing.  The system will control and monitor tool consumption and spending with reporting for complete visibility. The main benefits of the Guhring Tool Management vending solutions include 24/7 controlled tool availability and prevention of production stoppages due to tool availability. It will also eliminate loss and theft, create employee awareness of tooling costs and the system can communicate with customer IT systems.

Recalling specific product lines that have supported LMS Precision, Scott continues: “We had a lot of joy with the Guhring VA Series drill and now there is the new InoxPro drill as well, so this is bringing us even greater runtimes than ever before. We use Guhring on everything, from end mills such as the high-speed rippers, the through coolant drills, high-speed steel drills, stub drills – absolutely everything.”

Adding to this, Guhring’s Chris Bush says: “LMS use a complete range of our tools and they machine so many different types of material, they have to have material specific cutters as well as general-purpose cutters. They use the whole spectrum of our tooling range. With the range of stainless steel that LMS machines have; the new InoxPro is perfect for them. The Inox Pro introduces a new grade of carbide, so it is a much tougher carbide with a new geometry that is specifically for titanium and stainless steel. We also have the new Perrox coating on there as well. This is a much tougher wearing coating that is a lot smoother and this delivers optimum swarf evacuation.”

“The benefit of using Guhring as a supplier is that we manufacture our carbide. We can make our own grades for specific applications, so we have made tougher grades of carbide that are not as brittle as carbides from other manufacturers. This makes it perfect for challenging applications in titanium and stainless steel.”

Alluding to the application of the latest generation of tools, Scott comments: “The latest tools have given us the confidence to run lights-out, reducing the number of tools we need to stock and giving us full visibility of all tool usage and tool performance. This is especially the case with the VA Series drill. With that drill, we can now run over 1200 parts over a period of 15 hours on 316 stainless, drilling a 10mm diameter hole at 17.65mm deep with no problems at all. It’s absolutely great. The confidence it has given us is incredible. We have worked with Guhring for 35 years, and the products and support are great. The relationship we have and the products are brilliant.”

Concluding on the partnership, Chris Bush continues: “We have built a brilliant relationship and we are looking forward to the next 35 years. LMS have got exciting new projects coming through and new machines that they are investing in. Combining their technology and the advancement of materials, there will be plenty of exciting new challenges ahead and we relish the opportunity to deliver results long into the future.”

A visit to CERATIZIT    for technical training

CERATIZIT recently invited West Pharmaceutical Services to their Technical Centre on the Advanced Manufacturing Park for one of their technical training days. This facility allows customers to receive in-depth cutting tool training and gain technical expertise from CERATIZIT.

West Pharmaceutical Services has been a valued customer for several years and was invited to the technical training day, by Iain Tattersall, Technical Sales Engineer for CERATIZIT UK & Ireland Ltd, who regularly visits the company, along with CERATIZIT Application Sales Engineer Vince Witham, to provide technical and tooling support. The invitation enabled the Cornish customer to be brought up to speed on CERATIZIT’s latest innovations, and advancements in tooling and be shown the latest and most advanced machining techniques that can then be transferred to the shopfloor. More importantly, training days, such as the ones CERATIZIT run every week, help to fill the skills gap present in the engineering industry. Realising the importance of passing on the knowledge that they have learned from years of industry experience, younger generations are encouraged to take part in these training days to ensure these technical skills are not lost in the future. Sharing innovative machining techniques practises and skills, CERATIZIT training ensures that customers get the most from the company’s tooling. 

The day started with a morning of in-depth theoretical training which was delivered by Shaun Thornton, Technical Manager for CERATIZIT UK & Ire Ltd. Covering everything from materials, tools and sustainability, to speeds, feeds and cutting data, this extensive training equips customers with a solid foundation that will be useful in maximising the performance and profitability of machines. Taking time to answer questions and ensure that everyone has followed everything covered in the theoretical training, Shaun then led the customers downstairs to the workshop where they could put all this theoretical knowledge to the test. 

With a passion for passing on specialised technical skills, the latest machine techniques and the most up-to-date practises, the engineers at the Tech Centre planned an afternoon of practical learning whereby guests could incorporate the morning’s theory with some engineer-led machine demonstrations. After lunch and a chance to recharge, the afternoon’s practical training began with an interactive cutting tool demonstration on the MAZAK Integrex I-250H. Allowing the customers to input the cutting data, the guests could see how each operation ran and which values of cutting data worked best for the specified machine conditions. Immersing guests in hands-on, interactive training, is at the heart of CERATIZIT training days. Furthermore, live video feeds from the machines, played on large screens throughout the workshop, meant that everyone could get a detailed view of how the operations were running and whether their cutting data had been calculated correctly. 

After the demonstration on the MAZAK, it was time for more interactive demonstrations on the XYZ machines. On the XYZ 800HD and the XYZ UMC 5X, the visitors were once again encouraged to work out the cutting data for themselves, before putting their knowledge to the test and running the specified programs. On the XYZ UMC 5X, guests took part in a machine demonstration whereby they were shown how their free aluminium pen pots, given out to customers on training days, were made. This machine demonstration also showcased CERATIZIT’s latest cutting tool technology; KOMflex and ToolScope. ToolScope is a process monitoring control system that can be retrofitted to most CNC machines. Monitoring spindle torque and live cutting data, this information can then be used to optimise things like tool wear and prevention of tool breakages and collisions. Pairing this with KOMflex, an actuated closed loop boring and probing system, the engineers demonstrated how these technologies streamline machining processes and prevent damages which occur thanks to the advanced monitoring they allow with ToolScope, while reducing the risk of scrapping costly components, with KomFlex.

Once everyone had finished their demonstrations and all questions had been answered, customers were given fully documented training booklets containing information on the tooling, machine demonstrations and cutting data that they had used throughout the day. After that, the customers headed home. Following on from the training day, Vince helped West Pharmaceutical Services to implement changes to the current tooling and cutting data back on-site in Cornwall. These changes, influenced by the training day, had an immediate positive effect on productivity, cycle times and tool life.  Continuing their strong working relationship with both Vince and Iain, West Pharmaceutical Services is regularly visited by both CERATIZIT engineers for unmatched technical support and tooling recommendations.

Automated deburring of cross bores

Automating processes requires analysis of deburring methods, a factor often overlooked. Knoepfel AG identified this and sought a solution from HEULE Precision Tools in the production of highly complex mechanical components and cross bores.

Manufacturers depend upon external specialist partners with a high level of expertise. One of these manufacturers is Knoepfel AG from Walzenhausen in Switzerland. The 50 employee business is focused on the production of complex, high-precision mechanical components and thanks to its process-oriented approach and ‘zero error’ mindset, Knoepfel AG is not only a pioneer for series production, but also well suited to produce small batches.

In recent years, Knoepfel AG has transformed from a small workshop into a leading manufacturer in its field. The company is continuously streamlining processes and thereby improving the range of services for its customers. For this reason, Knoepfel AG invests in automation and the most up-to-date production technologies to enable reliable and cost-effective production strategies.

Such a strategy was required some time ago in the production of a wheel bearing made of high-tensile steel. A convincing machining concept was quickly presented to the customer, whereupon production of the hundreds of components per year was started. After a few months, Knoepfel AG recognised further automation potential. The workpiece has intersecting cross bores with a diameter of 7mm. Until now, the resulting burrs on the internal bore intersections were being removed manually with deburring scrapers and brushes, which was extremely time-consuming. Now, this process step is fully automated so that the high-precision components will come off the machine finished and burr-free.

Knoepfel already uses mechanical deburring tools from HEULE Precision Tools for various applications. The official representative of HEULE for the Swiss market, Eisenbart GmbH, was consulted about the feasibility of automatically deburring cross bores. Thomas Eisenbart accompanied Knoepfel AG closely during the application analysis and coordinated a visit to HEULE’s production site in Balgach, during which not only the various deburring options were presented, but also the first tests were carried out with the COFA-X tool from the X-BORES series. This tool concept is always customised by HEULE to suit the specific application requirements of the customer. It is suitable for intersecting bores with a main bore-to-cross-bore ratio of 1:1, as well as for applications with axial offset.

During tests at HEULE, it became apparent that the workpiece material itself presented the greatest challenge, as the surface hardens due to heat produced during cutting. The tests resulted in modifications to the tool, after which Knoepfel carried out further testing. The deburring results delivered a high-quality and process-stable solution. The X-BORES tool has now been fully integrated into the series production.

By eliminating the time-consuming manual deburring, up to 12 minutes are saved per workpiece, which amounts to around 280 hours per year based on a production quantity of 1,400 workpieces. The elimination of manual deburring also enables the reallocation of the employee’s skills to carry out more valuable tasks. Daniel Boehrer, CNC turning specialist at Knoepfel, is also impressed by the new solution and especially by the long blade life: “I always check the tool after about 300 parts. Most of the time, it shows that the blade is still working perfectly.”

Thomas Dietsche, Head of Production and Technology at Knoepfel, is particularly pleased with the stable and reliable process: “We no longer have to worry about burrs remaining and can focus our attention on other challenges.”

🎧- Insert evolution continues to take shape 

The introduction of the ISCAR HELIMILL in the 1990s marked a significant milestone for milling tools. It revolutionised the design of milling tools with indexable inserts, establishing a new approach that would shape the industry for years to come.

This breakthrough was achieved using a parallelogram-shaped carbide insert, featuring a helical cutting edge formed by the intersection of the insert’s helical side and shaped top surfaces (Fig. 1). The HELIMILL concept offers several advantages.

Firstly, the consistency of the rake and relief angles along the insert cutting edge when mounted on a tool reduces cutting force variations and ensures a smooth cutting action. Secondly, the uniformity of the insert cutting wedge enhances its strength. Lastly, the helical cutting edge’s proximity to the imaginary cylinder generated by a rotating tool improves accuracy compared to the straight edge found in previous-generation milling inserts. These advancements elevated milling performance to new heights.

Over the years, continuous improvement has led to significant changes in the classical HELIMILL inserts. The helix of the cutting edge has become more aggressive and the top surface topology has become more intricate. Combined with advanced carbide grades, these new designs have ushered in a new level of performance. However, the parallelogram insert shape limits the number of indexable cutting edges to two.

To maximise the efficiency of cemented carbides, a new round of insert development was initiated. The successful adaptation of the helical cutting edge to triangular inserts addressed this limitation. The triangular insert concept not only provides three cutting edges but also offers additional benefits. When compared to other shapes with equal cutting-edge lengths, the triangular shape provides a wider central area. This allows for an increase in the central bore size, enabling the use of a clamping screw with a larger thread. As a result, the insert security is strengthened, contributing to the overall durability of the milling tool assembly. Additionally, the triangular shape enhances the ramping-down cutting capability.

Overall, the introduction of the ISCAR HELIMILL and its subsequent advancements have advanced the milling tool industry. The use of helical cutting edges and triangular inserts has significantly improved performance, accuracy, and durability, pushing milling capabilities to new levels.

A proximate successor to the HELIMILL is the HELI-3-MILL, a family of milling tools introduced by ISCAR in the last decade, featuring triangular indexable inserts (Fig. 2). The advantages of the ‘helical triangle’ highlight why this family has gained popularity in the market. However, it is important to note that this does not mean the triangle shape will completely replace the traditional parallelogram contour with helical cutting edges any time soon. The parallelogram shape still possesses its competitive edge.

Paradoxically, the narrow width of the parallelogram-shaped insert, which is considered a drawback when compared to the triangular shape, also offers certain advantages. Firstly, a narrower insert allows for an indexable design suitable for smaller tool diameters. Secondly, this insert geometry reduces the depth of the chip gullet, strengthening the cross-section of the tool body. This feature is particularly important for extended flute cutter designs where higher strength and rigidity of the body are crucial. 

The parallelogram insert structure also permits increased corner radii. Additionally, the classical shape is well-suited for high feed milling (HFM) inserts, which can be mounted in existing pockets, effectively transforming a 90-degree tool into an efficient HFM cutter. Moreover, the ‘helical parallelogram’ has a smaller overall length compared to the ‘helical triangle’ for the same cutting length. Therefore, it would be premature and incorrect to dismiss classical parallelogram inserts.

As a result, the development of 90-degree indexable milling cutters harmoniously combines both approaches, utilising both triangular and parallelogram-shaped inserts. While the triangular insert concept dominates modern designs, the parallelogram insert principle remains relevant. The HELIMILL platform continues to be updated with new advantageous products. ISCAR’s recently developed products related to milling cutters with parallelogram-shaped inserts demonstrate that the traditional design approach remains effective and capable of meeting the demands of modern manufacturing. Milling high-temperature superalloys and titanium (ISO S group of applications), as well as difficult-to-cut austenitic and duplex stainless steel (ISO M group), present challenges. Effective coolant supply, particularly pinpointed high-pressure cooling (HPC), can significantly reduce the heat load on the cutting edge, enhancing lubrication and chip removal.

This, in turn, leads to higher cutting data and enables larger radial engagements, resulting in a higher metal removal rate (MRR). Moreover, HPC facilitates the production of tighter curled chips, allowing for tool designs with smaller chip gullets and higher tooth density. Taking these factors into consideration, ISCAR has expanded its HELI2000 family (the latest version of the HELIMILL) by introducing new tools that incorporate the HPC option within the tool body. The design of  these tools has been optimised using computational fluid dynamics (CFD). They are available in both integral-body configurations and as relatively small-sized exchangeable    heads with indexable inserts, which are compatible with ISCAR’s modular systems MULTI-MASTER and FLEXFIT (Fig. 3).

HELI2000 integrates the HELIMILL and HELIPLUS families, combining their latest developments into a single portfolio. This includes the introduction of two new highly efficient carbide grades: IC5600, designed for machining steel (ISO P group), and IC716, specifically tailored for cutting titanium. Additionally, the insert range has been expanded with new cutting geometries. This includes inserts with a high positive chipformer for milling titanium, chip-splitting cutting edges for productive roughing and other designs. Furthermore, the range now includes inserts with reinforced cutting edges for high feed milling of hard materials up to HRC 60 hardness (ISO H group, Fig. 4).

These new products are also part of ISCAR’s HELIALU family, which consists of milling tools with parallelogram-shaped inserts for machining aluminium alloys (ISO N group). The expansion of this family includes indexable endmill heads with threaded adaptations for both MULTI-MASTER and FLEXFIT systems providing the option for HPC. The screw-in design configuration of the heads significantly enhances the customisation capabilities of HELIALU tools, allowing for a wide range of MULTI-MASTER and FLEXFIT shanks, adaptors, extensions and reducers to be utilised. Therefore, the development of the ‘helical parallelogram’ has not ceased, and the traditional HELIMILL continues to gain momentum. This development follows a gradual upward helix, revisiting past turns but at a more advanced stage, much like in dialectics.

🎧- The impact of ESG reporting on manufacturers

The introduction of mandatory ESG (Environmental, Social, and Governance) reporting is set to have significant implications for engineering businesses. Keith Davidson, Environment Partner at law firm Irwin Mitchell discusses how the upcoming ESG developments, starting in 2024, will fundamentally change the business landscape for engineering companies.

Recent and expected ESG developments

Although the term ESG (Environmental, Social and Governance) has been commonly used since 2004, it has not been a priority issue for most SMEs. ESG is used as a measure of socially responsible investing and for the last two decades ESG has primarily concerned international financial market participants such as investment funds, banks, insurers, pension funds and listed companies. 

Significant changes are on the horizon. The business landscape is set to undergo a transformation in the coming years due to three key developments:

• The introduction of the first-ever internationally comparable accounting standards for accounting periods beginning in January 2024, so companies worldwide will be judged according to their ESG performance.

• Mandatory ESG reporting has been introduced for large companies in the EU from 2024, and the rules will gradually extend to non-EU enterprises that do business in the EU.

• Increased legal obligations to manage supply chain ESG performance, specifically addressing Scope 3 greenhouse gas (GHG) emissions from upstream and downstream value chains.

New global standards for sustainability and climate-related disclosures

On 26 June 2023, the  International Sustainability Standards Board (ISSB) launched two international disclosure standards that become effective for accounting periods beginning on or after 1 January 2024: IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures. IFRS S2 requires the reporting of Scope 3 GHG emissions.  

It is up to each country to endorse IFRS standards. The UK is currently consulting on the creation of UK Sustainability Disclosure Standards (SDS), which will address this matter. A decision is expected by July 2024. The Department for Energy Security and Net Zero launched a call for evidence in December 2023 to help inform the government’s decision on whether to endorse the ISSB’s standards in the UK.

Increased mandatory ESG reporting 

Since 2015, the Non-Financial Reporting Directive (NFRD) required reporting of certain non-financial and diversity information by very large public-interest entities in the EU with more than 500 employees. 

The CSRD entered into force on 5th of January 2023 and extends mandatory ESG reporting for a much broader group of companies. This includes non-EU companies that do business in the EU. 

The CSRD is being implemented in phases. 

• The first phase started in January 2024 and is applicable to listed companies in the EU with over 500 employees already subject to NFRD, with reports due in 2025. 

• The second phase will start on 1 January 2025 and will be applicable to EU companies with at least two of the three following criteria (a) more than 250 employees, (b) a net turnover of more than 40 million Euros and/or (c) a balance sheet of more than 20 million Euros, with ESG reports due in 2026 on 2025 data. 

• Third country undertakings (including UK companies) with net turnover above 150 million Euros in the EU and who have an office or subsidiary in the EU must report in 2019 based on 2018 ESG data. 

CSRD organisations need to report according to new European Sustainability Reporting Standards (ESRS) which includes Scope 3 value chain emissions.

Corporate Sustainability Directive

On 14th of December 2023, a consensus was reached between the EU Council and Parliament on the Corporate Sustainability Due Diligence Directive (CSDDD), which requires companies to identify and prevent actual and potential adverse human rights and environmental impacts. 

The new due diligence duty extends to large companies’ own operations and their subsidiaries and supply chains. The CSDDD will apply to EU enterprises with over 500 employees and a global annual turnover exceeding 150 million Euros and non-EU enterprises and parent companies with over 150 million Euros generated in the EU. There are lower thresholds (250 employees and 40 million Euros) for ‘high impact sectors’ – textiles, clothing, footwear, food manufacture, agriculture, construction and mineral extraction. 

Failure to prevent or end adverse impacts can result in contractual relationships with suppliers being terminated. National supervisory/regulatory bodies will have the authority to impose penalties on companies not complying with due diligence processes with potential fines up to 5% of the company’s global turnover. There is also the risk of civil liabilities where NGOs and trade unions will have five years to bring a claim. 

Although an agreement of the draft text has been reached, there is not yet an agreed date for the application of CSDDD and the final text could still be changed. It is forecasted that CSDDD will enter into force during 2024 and will start to apply to large companies around 2027.

Requirement for doing business

CSRD requires the management of Scope 3 value chain GHG emissions and CSDDD will introduce a new due diligence duty to minimise adverse environmental and human rights impact throughout a company’s international supply chain. Larger companies subject to ESG and carbon reporting will request evidence of climate action and ESG performance from its  value chain.

Failure to produce ESG policies and strategies could result in SMEs losing key customers and missing out on new business opportunities. It’s no longer a ‘nice to have’, ESG will become a requirement for doing business. 

Access to finance 

ESG performance is expected to have a substantial impact on access to finance in the future. Compliance with ESG standards will increasingly be requested and monitored by lenders, investors, competitors, civil society organisations and employees. 

Management systems

To get prepared for CSRD and CSDDD, companies will need to ensure that there are proper governance procedures and processes in place to measure and manage ESG issues. A management system approach will ensure continual improvement. Engineering companies are well placed for this approach as many have already implemented ISO: 14001 and ISO: 45001.

Due diligence in transactions

There will be increased demand in M&A transactions for ESG desktop searches and audits as part of technical due diligence and the need for ESG and climate clauses in legal documentation.

ESG real estate strategy

A large part of a company’s impact on the environment and the enjoyment of its workforce relates to the quality of its real estate assets. There will be an increased demand for ‘grade A’ accredited space and ‘Net Zero’ buildings and every stage of the property’s lifecycle from design, acquisition, occupation and disposal will need to consider sustainability issues. There will be a greater use of green leases and the focus needs to shift from data sharing to collaboration between landlords and tenants in terms of planning and costing of works.

Companies will be judged on ESG pledges

CSR (Corporate Social Responsibility) policies were often seen as a polish for corporate reputation. Now that ESG metrics and disclosure standard have been agreed in ESRS and IFRS and ESG performance can be compared between companies, ESG reports will be subject to greater scrutiny and ESG commitments must be put into action.

🎧- Green light for Nissan’s ambition 2030

Nissan’s devotion to electrification and manufacturing in Britain, is compelling. Huge recent investments underline the company’s green plans and long-term future in the UK. Will domestic suppliers benefit as the switch over to electric bites and new, high-volume components are needed? By Will Stirling

It’s June 2016 and the EU Referendum result is in. Shock: the British public voted to leave the European Union. Pandemonium ensues. Prime Minister David Cameron resigns. The cost of exports to the EU will certainly rise. A business story sharp in the memory was Nissan’s then Chief Executive, Carlos Ghosn, warning that the carmaker could stop investing in its Sunderland plant if EU export tariffs were imposed once the UK left the bloc. New PM Theresa May made a famous deal with Nissan to neutralise the effect of Brexit on its trading conditions. But for a moment, Nissan – with the UK’s biggest car plant – had a public wobble about its future here.

Fast forward to March 2024 and things could not be more different.

Carmakers are seemingly vying to be the greenest on the market, but Nissan’s net zero plan is surely hard to beat. Last November, Nissan heavily ramped up its EV36zero strategy, a roadmap to electrification that it had launched in 2021. The roll call of investments was eye-catching. The company will build three fully electric models at its Sunderland plant as part of a new £2bn investment, which is on top of the £1bn it had already committed under EV36zero to create an electric vehicle (EV) hub. 

More battery gigafactories are planned; with AESC Envision’s original battery plant, there will be a total of three gigafactories in Sunderland by 2030. “There will also be a renewable energy microgrid, that will deliver 100% clean electricity for both Nissan and the suppliers around the plant, further action to accelerate that journey to carbon-neutral manufacturing,” said a press spokesperson for Nissan Motor Manufacturing UK. The third gigafactory will be needed to supply the expanded Sunderland plant and may have the capacity to sell batteries to other OEMs. Prime Minister Rishi Sunak said of the investment: “This venture will no doubt secure Sunderland’s future as the UK’s Silicon Valley for electric vehicle innovation and manufacturing.”

Many UK customers know the Leaf, the first mainstream electric car to be built in the UK, and for EVs, Nissan also produces the Ariya and the Townstar small electric van. More than one million Nissan EVs have been sold to date, and more than one-third of their batteries were manufactured at the AESC Envision plant, in Sunderland. The ‘Nissan Ambition 2030’ strategy’s aim is that all passenger car sales will be EVs in Europe by 2030.

As well as the multiple carbon-cutting projects in Sunderland, where over 6,000 people are employed, Nissan recently unveiled three new head-turning concept electric vehicles (not for manufacture in the UK): Nissan Hyper Urban, Hyper Punk, and Nissan Chill-Out. The job of these futuristic concept cars is to inspire take-up of the new production EV models. In fact, Chill-Out will be the design for the next-gen Nissan Leaf.

At the launch event on 24 November 2023, Nissan’s global president and CEO Makoto Uchida, said: “Exciting electric vehicles are at the heart of our plans to achieve carbon neutrality. It means our UK team will be designing, engineering and manufacturing the vehicles of the future, driving us towards an all-electric future for Nissan in Europe.”

As a nod to the prevalence of greenwashing, Uchida-san spoke of ‘Nissan Ambition 2030’ being not a slogan, but a reality. “We have a vision of exciting electric vehicles, a vision where your car can help your community manage energy, a vision where Nissan becomes a truly sustainable company, where our actions have a positive impact on the environment.”

In addition to the late 2023 investment, the UK government awarded £15m of funding for a £30m collaborative project led by Nissan to support its carbon-cutting programme.

e-POWER offers a hybrid solution

And it’s not all about pure electric, as hybrid vehicles have proved popular while EV price tags remain high. Seen as Nissan’s answer to mild hybrid, e-POWER is its unique electric-drive powertrain that integrates a petrol engine that generates electricity, and a motor that transfers the power. Since its debut in September 2022, more than 100,000 vehicles powered by Nissan’s e-POWER have been delivered. e-POWER utilises motor control technology cultivated in past EV development activities, powertrain integration technology and energy management technology. By changing the combination of electric-drive motors and power-generation engines, it delivers quiet driving with excellent response over a wide range of vehicles from compact cars to minivans and SUVs.

Manufacturing and supply chains

By investing in three new all-electric models and the total £3bn now being invested in EV36zero; jobs and prosperity from Nissan Sunderland are assured for decades to come.

The batteries, the most substantial component in an EV by value, will be supplied by Nissan’s gigafactories. Britain needs more battery capacity to satisfy future production. As part of the three new EVs announcement, Nissan said it had initiated a feasibility study to explore potential further gigafactory investments in the UK. Nissan’s batteries are an NMC design, nickel manganese cobalt, rather than other primary mainstream battery designs like LPF – but in fact, both are lithium-ion batteries. This could potentially boost demand for UK-sourced lithium, from suppliers like Imerys British Lithium, because from 2027, materials and parts sourced outside the UK and EU will face tariffs under the EU Trade and Cooperation Agreement. A problem for UK and EU battery makers is the rising cost of materials, especially lithium.

 But these vehicles also need power electronics, motors, inverters, transmission systems, DC converters, charger ports and other electromechanical parts.

Nissan’s UK business supports hundreds of component suppliers and is hugely valuable to the UK automotive industry, and the economy of the North East. Tier one suppliers such as Adient (seating), Unipres, which make press-formed and hot-pressed automotive components and body mountings are co-located at the Sunderland site. Under the bonnet, however, electric vehicles need different and fewer components. How will the switch to EVs affect Nissan’s suppliers, which rely on tens of millions of pounds in contracts?

“Our work on just transitions suggests that workers in the North East are more confident about the transition to making EVs than workers in the West Midlands,” said Professor David Bailey, Professor of Business Economics at the Birmingham Business School and a senior fellow of the ESRC’s UK in a Changing Europe programme. “The commitment of Nissan to EV production and sourcing locally made batteries is a large part of that, with a benefit to the local supply chain.” 

 “And yet there are still challenges,” Bailey adds. “Nissan production has picked up from the lows of the Covid pandemic but is still at something like 2/3rds peak production back in 2016. Furthermore, looking forward to the switch to making EVs will need far fewer components than making ICE cars. That will mean fewer jobs in the local supply chain. Diversifying the supply chain will be crucial for maintaining manufacturing capacity and ensuring a just transition.”

Carmakers compete to be green

As sustainability is a much stronger criterion for consumer purchases now, car companies compete to show their low-carbon, sustainable business credentials.  In an analysis by information site Eupedia, that averaged the ‘green’ rankings of car and tyre makers by different organisations’ green monitors, including S&P Global and the Carbon Disclosure Project (CDP), Nissan ranked 9th among 22 car OEMs. It scored 100% on all CDP metrics but scored 70 on the CSRHub, while the top 10 scored from 82 to 95.  CSRHub provides ratings of Corporate Social Responsibility (CSR) using 12 indicators of employee, environment, community and governance performance. Nissan’s new Ambition 2030 is likely to pull up these scores when the green and governance actions have had time to bed in.

Certainly, Nissan’s devotion to green vehicles is a welcome boost to the EV industry, which is suffering. Private sales of EVs have slowed – 2023 orders were flat in 2022, according to the SMMT, the Society of Motor Manufacturers and Traders. A recent House of Lords Environment and Climate Change Committee report on the EV industry says the UK’s EV strategy needs a recharge. Some of this is due to a seemingly coordinated anti-EV campaign in the media. Quentin Willson, the former TV motor journalist, writes in Just Auto: “Anybody remotely involved with EVs, and electrification, will have seen relentless anti-EV narratives in the media over the last two years. Some papers run an anti-EV story every day – literally.” Public opinion and public relations to promote EV’s benefits both need to move for the important changes happening at Nissan UK and elsewhere to realise their full potential.

The power of apprenticeship support

The Close Brothers SME Apprentice Programme contributes to the funding of new apprentices in the manufacturing sector in and around the Midlands, helping local SMEs secure the skills they need for the future. 

Now in its ninth year, it demonstrates the funder’s long-established and continued commitment to helping SMEs and their local communities grow, succeed and thrive. Steve Gee, CEO, of Close Brothers Asset Finance, Industrial Equipment Division, provides insight into the Programme and the long-term partnership with The University of Sheffield Advanced Manufacturing Research Centre (AMRC) Training Centre.

The Close Brothers SME Apprentice Programme has partnered with The University of Sheffield AMRC Training Centre since 2015. How did this come about?

At MACH 2014, two main issues were being discussed – access to finance and new blood coming into the engineering industry.

 We came up with the idea of sponsoring young people to enter the engineering sector as SMEs were still struggling after the financial crisis (2008 onwards), which had impacted them a few years earlier.  We spoke to the Manufacturing Technologies Association (MTA) and they made the initial introduction to The University of Sheffield AMRC Training Centre – the rest is history!

Why have you been doing this, and what is in it for you?

It’s about giving something back. The Engineering and Technologies sectors are very important to us. We support them in many different guises, not only providing funding for new technology, but also as part of our responsibility to help address the social and economic challenges facing businesses today, and the apprentice sponsorship is a great example of this.

There’s been a noticeable positive shift in the attitude towards apprenticeships over the past years – why do you think that is the case?

I think at last it is getting the profile it deserves. It’s not cheap to invest in apprentices – and it’s important firms see it as an investment and not a cost. Handled correctly, apprenticeships can help an SME flourish and at the same time develop the individual apprentice.

University isn’t the right path for everyone – would you encourage school leavers to consider apprenticeships?

University is just one route available to young people and it’s a good one, but it’s not for everyone – my personal preference was to get out into the world and build experience and also some income! 

 If you speak to apprentices at the end of their apprenticeship, you will find many are more rounded than some people who’ve gone down the university route because of the practical, hands-on nature of their education – and they have five years more income to show for it.

According to the research, 90% of manufacturing and engineering firms feel that apprenticeships are at least partly the solution to the UK’s skills gap. What’s your view?

I agree entirely. There are skills gaps in most sectors – including engineering and finance. We need to embrace the ideas and practices of today’s younger generation – otherwise, we will stand still, which in today’s world means you can get left behind.

Many firms (60%) say that if more financial assistance was available, they would put someone forward to participate in an apprenticeship scheme. Would you encourage others to follow in close brothers footsteps?

It’s about seeing the bigger picture. I believe we all have a duty to look at where. As ‘UK PLC’, we need to concentrate our efforts and money. I would definitely encourage other companies to support apprentices – we know first-hand what a hugely positive impact they can have.

Renishaw to showcase British engineering excellence 

Over the last 50 years, Renishaw has established an ecosystem of end-to-end smart manufacturing technologies designed to transform shop-floor productivity, capability and efficiency. At MACH, it will exhibit its extensive range of smart manufacturing technologies.

“Globally competitive production performance and costs are inextricably linked to smart manufacturing. The manufacturing technologies are designed to maximise throughput and minimise costs and waste in all its forms. Renishaw will showcase these smart manufacturing solutions on home soil,” says Jonathan Archer, General Manager EMEA North & Director Renishaw UK Sales Ltd. 

“This year, we are particularly excited to demonstrate Renishaw Central, our factory connectivity and data-driven manufacturing platform. The software allows you to use actionable data productively for closed-loop CNC automation, visualisation, and the ongoing optimisation of processes to maximise output, quality and productivity.” 

Renishaw Central collects, collates, and presents actionable manufacturing process and metrology data, which can be used to monitor real-time performance across CNC machine tools, measurement systems and Renishaw additive manufacturing machines. Visitors will experience a real-time demonstration as Renishaw Central digitalises, visualises and controls CNC machining and integrated metrology processes on Stand 130 in Hall 18

In 1973, Renishaw’s co-founder invented a probe to automate measurement on CMMs. At MACH, an extensive range of technologies for automated process control and part verification will be on display.  

Making its UK debut at MACH is the world’s smallest wireless machine tool probe. Renishaw’s RMP24-micro measures just 24mm in diameter and 31.4mm in length. The probe offers exceptional repeatability and an ultra-low trigger force – ideal for use in compact machines that make precision miniature components. 

Other products on the Renishaw stand demonstrate the breadth of technologies available to support CNC manufacturing. The FORTiS™ range of enclosed encoders for challenging environments allows machine tools and systems builders to meet high performance and uptime requirements while achieving energy savings up to 91% without risks in reliability. Scale lengths up to 4.24m can now be supplied for larger CNC gantry mills, turning machines, or grinders. FORTiS encoder systems with industry-leading vibration resistance are being adopted widely across a range of CNC machine tools and new emerging applications such as giga-casting for the automotive industry. 

CNC machine calibration and performance optimisation products, including upgraded CARTO software, demonstrate the enhanced performance monitoring of precision machinery.  

Also on display will be the latest CMM technology with the REVO® 5-axis multi-sensor system, featuring an increasingly comprehensive range of sensors and probes for complex inspection applications on a single CMM. The system’s infinite positioning and rapid measurement also reduce the requirement for complex styli configurations and calibration time. The benefit to users is increased throughput and significantly reduced shopfloor and quality lab measurement costs. 

A special exhibit on the Renishaw stand is the track bike developed by the British cycling team for the 2020 Tokyo Olympics. Renishaw provided additive manufacturing expertise to develop and build innovative ultra-lightweight parts for the bike that contributed to the team winning seven track medals. This partnership has since been renewed for the development of a new model ahead of the 2024 Olympics in Paris. 

“It’s a privilege for us to host the British Cycling team’s key feat of engineering on our stand,” says Archer. “The delivery of this model represents the culmination of years of dedicated collaboration, innovation, and collective passion. This partnership aims to increase the bike’s speed and performance through enhanced design. And the result is the perfect union of British engineering and British Olympic talent.”

Hurco 5-axis focus 

Regarding Hurco Europe’s prismatic machining equipment at MACH 2024, the accent will be on 5-axis machining as well as automation of both 3-axis and 5-axis vertical machining centres (VMCs). There will be a Hurco ProCobot Profeeder assisting the production of parts on a VM20i 3-axis VMC and an Erowa Robot Compact 80 feeding a trunnion-type 5-axis model, the VMX30Ui. 

On Stand 180 in Hall 6, the ProCobot picks and places components and removes them after machining with the app running directly in the Max 5 control and visible on the screen. Minimal information needs to be entered to set a job, so changeover time can be as rapid as 30 minutes, making plug-and-play, small-batch automation a reality. The Erowa cell transfers the workholding as well as the part on a pallet. The choice of system depends on the application. Both solutions lend themselves well to Hurco’s typical customers. 

Hurco SRTi 5-axis VMCs are popular because they have a swivelling spindle head and flush rotary table, a configuration that can be used as a 5-axis production centre or a 3-axis machine that exploits the full working volume. A VMX42SRTi with 1,067 by 610 by 610mm travels will represent this range at the show. It has directly-encoded torque motors driving both the B-axis spindle and C-axis table. Linear scales and 20-bar coolant through the spindle are standard features.

Another Hurco 5-axis machining centre at the exhibition will be the cantilever-type VC500i. Ergonomically designed for easy operator access, it has a 520 by 450 by 400mm working volume and a ±100-degree swivelling trunnion carrying a rotary table, ideal for machining five faces of a component in a single set-up. As with any 5-axis centre, it drastically reduces the number of separate operations needed to completely machine a part compared with using a 3-axis machine.

A VMX60Ti 3-axis VMC equipped with a rotary-tilt table will demonstrate the versatility of this alternative 5-axis machining arrangement, particularly for prismatic machining of shaft-type components. 

In addition to the popular 3-axis VM10i, there will be a VM ONE 3-axis VMC with a smaller Z-axis travel of 356mm. It addresses a need, especially among subcontractors, for an entry-level machine that is super-compact, yet still capable of producing prismatic parts weighing up to 1,500kg.

Powered by proprietary WinMax software, the Max5 control includes a solid model import option that allows 3+2 routines to be programmed on the shop floor from an IGES CAD model imported as a STEP file. It is fast, uncomplicated and takes the load off the manufacturer’s CAM stations. 

For the last 20 years, Hurco Europe has been sole agent in the UK and the Republic of Ireland for sales of German-built Roeders machining centres. A 5-axis, ± 115-degree trunnion, HSK E40 model will be on the Hurco stand capable of machining workpieces weighing up to 60kg within a 500 by 500 by 300mm working volume. The RXP501DS achieves very fine surface finish on components thanks to its extremely rigid, 7-tonne construction.

A new range of four driven-tool CNC turning centres was launched by Hurco at the last MACH show, during which the 8-inch chuck version was exhibited. This year it is the turn of the 10-inch chuck variant to appear, the TMX10MYSi. All models include a programmable W-axis to position the tailstock or sub-spindle. 

The turning centres offer higher specifications and performance than the established and popular TMi and TMMi models. The major differences are higher power and speed plus a larger, heavier machine frame and the addition of a Y-axis to allow more versatile machining. 

Two smaller capacity Hurco CNC lathes with a chuck capacity of 8 inches will be on show, the TM8i and the TM8Mi with axial-driven tools. The latest models have a larger spindle bore than their predecessors, as well as roller guideways and a more compact footprint. 

Citizen reaffirms its position at MACH

Citizen Machinery will reaffirm its position as a leading supplier of bar-fed lathes, but also as a pioneer in automation technologies at MACH. The company’s patented LFV chip-breaking software, its wealth of options for automating production, and integral laser cutting in its Cincom sliding-head lathes are three examples.

In Hall 20 on Stand 361, the focus will be on Citizen’s proprietary LFV operating system software that ensures efficient chip breaking and every sliding-head mill-turn centre on the stand will have this functionality. 

A versatile variant has been added to the Cincom L20 sliding-head CNC turning centre range from Citizen Machinery. The L20-XII, which has a 135-degree swivelling B-axis mounted on the gang tool post for working at either of the opposed spindles, is now available with an ATC for swapping up to 30mm diameter cutters in a chip-to-chip time of four seconds. The total number of cutters that may be mounted in the working area of the Cincom L20-XIIATC is 34, providing considerable flexibility to ensure that components are machined in as few set-ups as possible, normally one. Visitors to the Citizen Machinery UK stand will learn that the configuration of the 12mm bar capacity Cincom L12-X ideally suits it to the production of dental abutments and implants, as well as medical industry parts in general. 

A modular tooling system has been adopted for the gang and back tool posts and an extensive variety of tooling layouts is possible, which includes the ability to drill angled holes. The maximum number of tools that can be deployed is 38. Unlike on other Cincom L12 models, a built-in 12,000rpm motor drives the counter spindle, reducing acc/dec times for higher productivity. 

Two Cincom lathes on the stand will have 32mm bar capacity, including the L32-VIII, which accepts 38mm stock if the guide bush is removed. It is one of four machines with exclusively gang toolposts in a modular range that allows a user to select a precise specification to suit the intended applications while retaining the option of adding extra functionality later. 

The other model is Citizen’s flagship sliding-headstock lathe, the 10-axis Cincom M32-VIII is a 10-station turret, which runs on hardened box ways, and incorporates a tooling system employing a single 2.2kW drive to power the live cutters. The gang tool post has been equipped with live tools powered by a 2.2kW motor, as well as a programmable, 9,000rpm B-axis to enable simultaneous machining in five CNC axes, while the back tool post with Y-axis has adjustable-angle tooling. 

One of the larger bar capacity CNC lathes in the Citizen Machinery product portfolio is the 12-axis Miyano ABX-64THY, a fixed-head model with twin-opposed C-axis spindles and three turrets moving over box ways for maximum rigidity. The turning centre is ideal for continuous production of components from bar up to 64mm in diameter. The maximum component diameter when chucking is 165mm. The three turrets, which have 80mm of Y-axis movement, can all be cutting simultaneously to achieve very high levels of productivity. 

The first fixed-head lathe in Citizen Machinery’s Miyano range to have the company’s LFV software in a FANUC control system was the 42mm bar capacity ANX-42SYY. It features 10 CNC axes including a ± 35mm Y-axis on both the upper and lower turrets in addition to X- and Z-axis movements, enabling the production of complex components to tight geometrical tolerances.

Complex components up to 65mm in diameter may be turned and milled from bar in a new Miyano fixed-head lathe. The eight-tonne BNE-65MYY is equipped with two turrets having Y-axis travel in addition to X- and Z-axis movements. Contributing to high productivity are fast rapid traverses up to 20m/min, plus main and sub spindles with generous power ratings of 18.5kW and 11kW respectively. Rotary tool specification is also impressive at 4kW 6,000rpm.

Building on the strengths of previous generations of Miyano fixed-head mill-turn centres, the BNA-42SY is one of Citizen Machinery’s latest additions to the range. The latest FANUC 0i-TF Plus CNC system with 10.4-inch colour LCD screen controls the machine.

The GN3200W is a twin-spindle, fixed-head lathe equipped with a high-speed loader for high productivity. The compact machine width is 33% narrower than previous Miyano models and the required floor space has been reduced by 27%, realising significant space savings. 

Colchester is turning up to MACH

At MACH 2024, Colchester Machine Tool Solutions will be emphasising why it has been a trusted and industry-leading manufacturer of machine tools for over 130 years. On Stand 240 in Hall 6, Colchester will be showcasing its latest product range with a varied line-up of CNC and manual machine tools, suitable for all milling and turning projects.

Leading the line-up is the Storm VL-550 VMC, the most compact model in the range utilising linear guideways technology and capable of the most demanding tasks with heavy-duty and precise machining.

New Knowledge Hubs initiative for MACH 2024

Reversing UK manufacturing’s poor record for adopting new technology will be tackled head-on at MACH 2024 as The Manufacturing Technologies Association (MTA) launches its new Knowledge Hubs initiative, showcasing how to adopt new technology to improve productivity and efficiency.

The programme showcases new technology that is readily available to UK manufacturers, helping them to understand the potential adopting such technology can bring to their operation.

The Knowledge Hubs initiative will have dedicated stands across the event, each focusing on a particular type of technology including automation and robotics, sustainable solutions, additive manufacturing, consumable tooling, and data and artificial intelligence. In recognition of the importance being placed on these hubs, each is being managed by one of the specialist centres from the High-Value Manufacturing Catapult, such as the Manufacturing Technology Centre (MTC) and the Advanced Manufacturing Research Centre (AMRC).

The Catapult network is recognised for its R&D work being conducted at its various centres.  The network collaborates with thousands of innovative businesses across a wide range of sectors, including manufacturing, space, health, digital, energy, transport, telecoms, the urban environment and many others.

The MTA, which organises the MACH event has been campaigning for greater adoption of new technology for some time. It will expand upon this at MACH 2024, which opens its doors at the NEC in Birmingham on 15th April, by explaining that implementing proven, readily available techniques in manufacturing processes is the fastest way to boost the UK’s output.

James Selka DL, CEO of the MTA, said: “The MTA is part of a united front of UK manufacturing organisations, along with the Manufacturing Technology Centre (MTC) and MACH 2024 Headline Sponsor Lloyds Bank, to increase the uptake of technologies such as automation and robotics. Only by embracing what the hubs are trying to achieve will the UK restore its position as a sovereign manufacturer, re-establishing itself as a major player on the global stage. To have brand-agnostic input from the High Value Manufacturing Catapult network, running our Knowledge Hubs, is an indication of the importance these organisations place on our initiative.  Combined with the ability to see advanced technology, live and in action, in a fully working state – MACH 2024 is a must-visit for all the UK’s manufacturing community.”

The need for this approach was recently brought into sharp focus in a new report highlighting the UK’s lack of investment in technology and its poor adoption of robotics in industry. The figures, from the International Federation of Robotics, showed the UK languishing outside the top 20 developed nations. 

MTC Chief Automation Officer, Mike Wilson, commented: “Robotics and automation is key to solving the UK’s productivity puzzle.  This underpinning technology will help manufacturers achieve high productivity and net zero aspirations while solving some of the UK’s labour shortage issues.”

The Sustainable Solutions Knowledge Hub, sponsored by Lloyds Bank, will guide manufacturers on how investing in energy-efficient technology now, backed by government incentives, can help offset energy cost increases, improve business fitness for the future and help balance the ‘cost of doing business’.

The Additive Manufacturing Knowledge Hub is designed to help visitors learn how to develop, adopt and use additive manufacturing and 3D printing technology in their processes.  Expert advice and wayfinding will be on offer from AM-UK on how to utilise the technology for making production parts and products directly from design data – building accurate components to obtain the final shape with minimal waste.

The Consumable Tooling Knowledge Hub is where visitors should head to receive impartial advice on how to optimise their machining processes and deal with machining challenges.  The Hub will offer advice on matching the most suitable cutting tool material and insert geometry with the workpiece material to be machined, through key considerations such as cutting data. 

The Data and AI Knowledge Hub will explore how SMEs can use this technology to drive growth and innovation in manufacturing by measuring the output of their current operation, looking for opportunities to improve and ensuring supply meets demand.  The Knowledge Hub aims to provide advice and wayfinding, addressing the manufacturing applications that can be supported by data, technology and automated processes.  

OPEN MIND sparks productivity gains for future

With a machine shop boasting over 40 machine tools that provide exceptional flexibility and capability, Future Advanced Manufacture (FutureAM) has carved an incredible position and reputation in the subcontract manufacturing arena. However, when the company found its existing CAD/CAM system lacking capability in several areas, the Cheltenham based business turned to OPEN MIND Technologies and its industry-leading hyperMILL CAD/CAM system. 

The shopfloor at FutureAM has a diverse mix of machine tools that include 3 to 5-axis machining centres and multi-axis turning technology from brands such as Doosan, Mazak, DMG MORI, XYZ, Colchester, Hardinge, Bridgeport, Correa, the YMT Hedelius and many more. Applied to projects with tier one suppliers across oil & gas, nuclear, marine, defence, aerospace, space and medical industries, the Gloucestershire company also offers a complete project management service from design, programming and machining to inspection and testing.   

Working closely with Future Advanced Manufacture, Justin Talboys-Cotton, a Sales Manager at OPEN MIND Technologies recalls: “When Future Advanced Manufacture initially came to us, they took a couple of seats and trained a few people, so hyperMILL could run alongside their previous system. This was a slow and managed integration but eventually, they decided to get one seat for each programmer. This has been supporting the comprehensive training plan where we slowly feed all employees through a training programme to learn hyperMILL. This provides a common footprint and thread through the machines and the programmers in the business.” 

Justin adds: “Previously, FutureAM had no graphical simulation and they were running programs to the best of their knowledge on the machines. By adopting hyperMILL Virtual Machining, FutureAM now has a full digital twin of the machines running full NC code simulation. It doesn’t just stop there; they have also invested in Optimizer module which will automatically work out the best and most optimal solution to fit their required tool path within the machine envelope. With their previous supplier, FutureAM were limited to milling only. hyperMILL has now also given this customer turning capability – all in one supply.”

Oliver Allen the Head of R&D at Future Advanced Manufacture says: “With our previous CAD/CAM supplier, 5-axis machining was more a bolt on to their CAD system whereas with hyperMILL, the 5-axis suite is incorporated into the system and OPEN MIND provide full support for this. Our previous supplier could not offer that.”

Adding to this, Justin says: “hyperMILL is an all-in-one system that has CAD and CAM together, whether that is 2.5D, 3D, 5-axis machining or turning. We are providing all of this in one package whereas previously FutureAM had two or three systems that they were dipping in and out of. With hyperMILL, the learning curve and daily operation are now much easier.”

Commenting upon this, Oliver continues: “Now that everyone here is using hyperMILL, it’s very apparent with productivity levels increasing and efficiency improving with the company subsequently making more money. Therefore, the board is extremely happy with their purchase of hyperMILL from OPEN MIND Technologies.”

Concluding on this, Justin says: “There is a lot more potential for future capability at FutureAM. Some of the machines are on post-processors and we now have virtual machining technology  on the new machines, so I think we will progress other machines on to  hyperMILL Virtual Machining in the future. We can also look at doing more advanced training plans. We have already conducted the standard training with additional staff working through the standard training program, but there is the opportunity for further bespoke and more in-depth training to make the staff at FutureAM true experts in programming to their specific needs.”

Many customers of Floyd Automatic will be familiar with Applitec’s TOP-Line twin screw insert program, which is the industry’s top-performing solution. There is no better compliment than to ‘copy’ the best, and therefore many competitors have now introduced their interpretation of the Applitec TOP-Line.

The exciting new PRO-Line is Applitec’s response to the arrival of competitor systems. Once again, Applitec has taken innovation to a new level with a solution that offers a lower-cost insert with the same Applitec quality – the recently launched TOP-Line range of PCD inserts. The new 730/740 series of PCD inserts have been introduced for the machining of non-ferrous materials like lead-free brass and aluminium. 

Concerning form tools solutions, Floyd will present the latest product lines from Schwanog. The machining of complex forms can be a significant challenge for manufacturers, but luckily, Floyd Automatic can now provide remarkably precise form tools for even the most challenging of materials. 

The scope for the Schwanog form tools extends way beyond ‘cut-off’ tools and the series is suitable for external and internal turning, grooving and much more. Regarding external turning, grooving has emerged as a more efficient solution compared to single-point turning for almost all machine types in numerous industries. For example, the Schwanog system can be created with OD grooving tools, OD grooving tools for Escomatic and rotary transfer machines, shaving tools, skiving tools, modular MSIK systems and DCI Swiss-type grooving systems.

Perfect for reaching the most challenging of surfaces when 5-axis machining, the 4101 Series is a 4-flute long-length tool with centre-cutting to reach the most inaccessible of surfaces – demonstrated by its 220 degrees of inclusive cutting. Manufactured with an AlTiN coating and a 30-degree helix, the 4101 Series is ideal for applications on steel, stainless, cast iron and aerospace-grade alloys. With ball diameters from 2 to 16mm, shank diameters from 6 to 16mm and an overall length of up to 100mm, the 4101 Series offers incredible rigidity, flexibility and surface finishes when machining the most challenging of parts. 

For trochoidal machining, ITC will demonstrate its extensive portfolio with the 5021, 5031, 5041, 6051 and 6054 appearing as just a few of the stand-out performers.  The 5021 Series is a long-reach Cupro-coated 5-flute end mill with harmonic fluting and a variable helix for unsurpassed performance under the most challenging of cutting conditions. Accompanied at MACH by the short-length 5031 and the necked 5041 Series, the end mills are available from 3 to 20mm in diameter. The 5-flute trochoidal tools will be accompanied by the 6-flute 6051, 6071 and 6054 Series which are perfect for machining steel and exotic materials. 

For the machining of aluminium, MACH will provide a launchpad platform for the 3301 and 3204 Series of end mills. The 3301 for heavy material removal is a long-length 3-flute series with a centre-cutting 38-degree helix geometry and impressive reach characteristics that are matched by its stability. Available in diameters from 6 to 20mm, the 3301 is available with an overall length of up to 150mm.

Guhring to premiere new products at MACH 

Guhring will premiere a host of new innovations at the MACH exhibition on Stand 331 in Hall 19. It will introduce new product lines alongside proven industry-leading ranges with a complete range of milling, threading, and drilling tools on show.

Guhring will give a MACH show premiere to the new RT100 InoxPro range of solid carbide drills for machining stainless steel and titanium alloys. When machining these challenging materials, tool wear can be a formidable opponent to your productivity and performance. The new RT100 InoxPro overcomes these challenges with its new geometry. This combines with an ultra-smooth Perrox coating that enhances wear protection and an optimised carbide substrate that provides a balance of hardness and toughness. Available with 3XD, 5XD and 7XD variants from 3 to 20mm diameter with 0.1mm increments, this through coolant series will improve feed rates and tool life by more than 50%. Guhring will also present its Micro Precision Drills, the RT100T and RT100XF as well as the HR500 reaming line and SpyroTec spiral fluted chamfer milling cutters at MACH.

The milling portfolio continues to rapidly expand. Since MACH 2022, the Birmingham manufacturer has added a wealth of innovations. This includes the new SkyLiner series of end mills for rough and finish machining of aluminium and non-ferrous materials. Especially suited for pocketing and wall applications with thin wall sections with depths up to 3XD, the new Alu RF100 SkyLiner F delivers surface finishes even at the highest feed rates. This 3-flute tool is offered in diameters from 6 to 20mm with axial through coolant ducts, a 0.2mm corner radius and a variable helix. Accompanying the Alu RF100 Skyliner F at MACH will be the Alu RF100 SkyLiner R. This series is the perfect solution for high-performance machining. 

Alongside these MACH debutants, Guhring will introduce favourites such as the RF100 Sharp, the ever-growing Diver Series of end mills and the RF100 Speed. The RF100 Sharp end mills made a MACH debut in 2022 and will return with an extended range to demonstrate how to address the issue of machining soft, tough and high-alloyed materials. The RF100 Sharp Series has an extremely smooth cutting action and profound chip removal capability. The smooth cutting action and the ability to be used in a wide variety of applications such as slotting, ramping, roughing, helical milling, finishing and trochoidal cutting, make the new RF100 Sharp the end mill of choice.

For the micro-machining sector, Guhring will showcase the RF100 Micro Diver. The micro-precision milling range is a universal tool for every material and application. Providing plunging and milling in a single tool, the RF100 Micro Diver is available in two variants, the 6808 and 6809. An innovative flute form that further enhances rigidity and eliminates vibration. The RF100 Micro Diver Series is suitable for cutting materials up to 48HRC at depths up to 5XD and is available with a cutting diameter from 0.79mm to 3.175mm. 

As well as demonstrating all the latest ranges, Guhring engineers will be on hand at MACH to discuss the scope of special tooling solutions that can be designed, developed, manufactured and trialled at the Guhring facility in Birmingham. Guhring UK has a team of expert engineers that can create productivity, cost, inventory and cycle time savings for UK manufacturers. 

As part of the stand at MACH, Guhring will also be demonstrating its extensive PCD cutting tool portfolio. The PCD milling tools are also available.

New tools for boring, milling, threading and turning

Paul Horn, the solid carbide tooling, carbide insert and tool holder manufacturer with over 25,000 standard products will introduce five new lines to the UK and Irish markets at MACH 2024. Wholly-owned subsidiary Horn Cutting Tools will be on Stand 210 in Hall 6 to explain the launches and exhibit a broad cross-section of its extensive tooling range.

An addition to the Horn Supermini boring, grooving and chamfering system will be announced, a variant with a precision-ground rake face designed for producing ultra-fine bores. The ground cutting edge is free from notches when viewed at a magnification of x200. It can be used to machine components with an inside diameter of just 0.3mm. Sharp insert geometry ensures process reliability, even with very small cutting feed rates. 

The Supermini Type 105 system insert requires only one tool holder for well over 1,000 insert variants. The carbide inserts are available coated or uncoated in various grades for a variety of applications, including hard machining up to 66HRc. The patented, droplet-shaped cross section has a vibration-damping effect and delivers repeatability during insert exchange. 

Horn has developed a new, solid carbide milling cutter range for machining stainless steel. The combination of substrate, macro and micro geometry, and IG3 coating exhibits high cutting performance and long tool life. The coating offers high-temperature resistance for machining steels alloyed with chromium, nickel and molybdenum.

The tools are offered in two types from stock. The DSHPR variant is suitable as both a finishing and a roughing tool and the geometry is adapted for trochoidal machining. Type DSR is suitable for very small parts and unstable workholding conditions, such as are frequently encountered in the medical and watchmaking industries. 

A new, high-performance SG3P carbide grade presents enhanced possibilities in terms of performance and tool life when whirling medical screws. It enables shorter cycle times for thread production thanks to higher cutting values. 

A long overhang can cause a turning tool to oscillate when boring internal geometries. In addition to causing chatter marks on the surface of the machined component, the vibrations can lead to a significant reduction in tool life. To help mitigate these difficulties, Horn has introduced a boring bar with adjustable damping so it can be set to match the amplitude of the oscillation generated by the machining process. 

The damping element, a carbide rod supported in O-rings, is adjusted from the outside by turning a screw to fine-tune the pre-tension of the rings. It allows the boring bar to be set accurately to minimise the vibration that is predicted to occur during a machining cycle. As standard, Horn offers the boring bars from stock in length-to-diameter ratios of 5:1 and 8:1. Higher ratios are available as special tools. In the case of grooving, Horn offers the S224 double-edged system. The manufacturer’s BK 224 cassette ensures a stable interface between the boring bar and insert. To increase process reliability further, the tools have an internal coolant supply.

Horn is also launching a new tool range for manufacturing brake discs. It includes solid CBN ISO inserts, mainly used for cast iron machining, and CBN-tipped full-radius and shaped inserts. Horn offers the solid CBN ISO S turning insert with eight cutting edges for roughing and finishing. Cutting speeds of well over 1m/min, depths of cut of several millimetres and feed rates up to 0.7 mm/rev are typical values. 

Additionally, Horn has introduced two different tool solutions for machining the heat dissipation grooves in the discs. The CBN-tipped S117 profile grooving insert is ideal in terms of cutting speed and longevity for large batch production. During the process, each groove is produced in just under two seconds in a single operation.

Heller to emphasise engineering support 

German-owned Heller Machine Tools whose factory in Redditch produces selected 4-axis and 5-axis horizontal machining centres will stress at MACH 2024 that this facility places it in an excellent position to provide customers with an elevated level of applications and service support. Celebrating its 50th anniversary in 2024, it is also a global competence centre within the group for top-level turnkey projects.

360-degree solutions is Heller’s name for its pre and post-sales services. Based on this principle, it provides users with solutions to maximise machine availability and productivity, helping them to produce parts reliably and at a competitive cost per part. 

The holistic Heller service includes time studies which are accurate to ±5%, evaluation of requisite workholding, consideration of automation and unmanned running requirements, built-in chillers for cooling the machine elements if they are required to achieve tolerance, tool life monitoring and broken tool detection.

A particular focus at the show will be Heller’s ability to supply turnkey cells for highly efficient machining of tough titanium and nickel superalloys, notably in the aerospace industry. In this connection, the machine manufacturer will stress the considerable range of different spindles that it manufactures in-house to suit a vast range of applications.

For example, the HMC on the stand will be an HF 3500 second-generation 5-axis model for which it is possible to select a DC (dynamic cutting) universal direct-drive motor spindle, rated at either HSK-A63 16,000rpm 56kW 180Nm or HSK-A100 12,000rpm 45kW 400Nm. There is also a PC (power cutting) spindle rated at HSK-A100 10,000rpm 45kW 360Nm and an HSK-A100 13,000rpm 45kW 228Nm SC (speed cutting) spindle. Two further options with an HSK-A63 interface are rated at 12,000rpm 45kW 228Nm (PC) and 18,000rpm 45kW 103Nm (SC). 

The 5-axis machine has a 710 by 750 by 710mm working volume. In this case, the machine will be exhibited without a DDT (Direct Drive Turning) rotary table and spindle locking function for turning tools.

To raise cutting performance, the Gen 2 design has a short distance between spindle nose and the centreline of the 225-degree swivelling trunnion and is available with twin motors and ballscrew drives for moving the trunnion/rotary table in the Z-axis, with position feedback via linear scales. The high-end PRO package offers more than 1G acceleration in all linear axes. 

Engineers will be on the stand to discuss the benefits of the new F 6000 5-axis mill/turn machining centre launched by Heller at the last EMO trade show, held in Hannover. It has been designed from the ground up following extensive research carried out amongst the manufacturer’s customer base.

Highlights of the new generation include new swivelling heads with integrated motor spindles d and an optional direct-drive torque table for carrying out in-cycle turning operations. A pallet changer is included, enabling easy integration later on of a rotary or linear pallet storage system.

To ensure that all of the above benefits are maximised in production, Heller’s design engineers have focused on clear and easy operation, as well as good accessibility to all work areas. Operation is simplified by the new Siemens Sinumerik ONE control, which is fitted as standard, and the convenient control unit in panel design with a 24-inch touch screen. At the same time, better access to the work area and the optional new SETUP-Assist software make it easier to prepare for the next machining process.

The main purpose of automated manufacturing in production centres is the reduction of idle times to optimise system availability. For this purpose, Heller offers proprietary automation solutions that can be optimally combined with its HMCs. 

Featured at MACH 2024 will be Heller4Industry, the group’s worldwide drive towards integration of its machine tools and controls into the Industry 4.0 environment. Within the multi-faceted portfolio is the HELLER4Services interface, which focuses on the transparency of digital manufacturing and maintenance. The module forms the basis for evaluating machine data and statistics to reduce downtimes. Additionally, visualisation of specific information such as status displays of axes and spindles enables a user to predict wear and implement preventive maintenance.

Starrag stand will be magic

At MACH 2024, Starrag will present new technologies that are yet to be seen in the UK. With so many machines receiving world premieres at EMO in September, the Starrag stand at MACH will be crammed with innovations. 

Stand 320 in Hall 18 will have everything from new machine technologies, virtual showroom platforms and the new global market position. The ‘meet and greet’ booth even promises light entertainment with a magician performing on the stand. 

At MACH, Starrag will be presenting its latest innovations from across the company’s diverse portfolio. From the Bumotec product range, Starrag will present its latest turn/mill product lines that can now be viewed in the company’s new virtual showroom (https://showroomvud.starrag.com/).

Destined to attract visitors is the new Bumotec 191neo that was featured at EMO in September. This complete machining solution enables manufacturers to produce parts from bars or blanks; and with new generation linear motors, 7-axes and 3 spindles with 5 simultaneous axes and up to 90 tools – this arrival will appeal to engineers visiting MACH. The new 191neo incorporates a new MMI touchscreen interface with a Windows-based PC and a host of additional features and automation solutions. 

Also new is the new Heckert H Compact Series. With the Heckert H Compact Series twin pallet horizontal machining centre, Starrag delivers the benefits of a horizontal with a compact footprint. The new Compact Heckert X series is fitted with a trunnion table that provides an impressive high-speed/rigid simultaneous 5-axis capability. It can also incorporate a high-speed table for turning with the Heckert T series. Designed with a monobloc mineral cast material base, the machine has been designed for high material removal rates. The machine has a complete range of spindles available from a 30,000rpm spindle for cutting aluminium through to high-torque or geared spindles for machining titanium as well as quill spindles for extended reach. 

Another newcomer to the Starrag family is the impressive STC1250 HD horizontal machining centre. As the latest addition to the renowned STC Series that has been designed to provide unrivalled economy in the machining of the most demanding aerospace structural parts, multi-blades and casings, the STC Series provides excellent static and dynamic properties as well as tried and tested rotatable head. The STC1250 HD offers a 1.25m by 1.25m pallet with a remarkably large work envelope for workpiece loads up to 5,000kg on the pallet. This is complemented by an X, Y and Z-axis travel of 2.2 by 1.5 by 2.1m with a swing diameter of 2.2m. The STC1250 HD is capable of reducing cycle times from Starrag’s current benchmark by a further 30% on large titanium and Inconel parts for the aerospace and power generation industries – making it the new benchmark for heavy-duty machining. 

The Starrag team will also be keen to present the merits of the new Droop+Rein FOGS HD at MACH 2024. Designed for large components, the Droop+Rein FOGS HD is a 6-axis overhead gantry-type machining centre available in a variety of dimensions with traverse paths from 3 to 31m in the X-axis, 3 to 6m in the Y-axis and 1.5 to 2.5m in the Z-axis. The Droop+Rein FOGS HD is an efficient 50 to 100kW powerhouse that delivers unsurpassed precision with fast and dynamic axes movement and an extremely high torque range from 2,400 to 7,500Nm.

🎧- NCMT celebrates 60th anniversary at MACH 2024 

NCMT is celebrating its 60th anniversary this year. In 1964, it was one of the first companies to sell CNC machine tools into the UK and Irish markets when it won the sole agency to sell and service Makino machining centres. Twelve years later, a second agreement was reached with Okuma, another Japanese manufacturer. 

In 2005, Makino-NCMT Grinding Division was established to develop and sell throughout Europe Makino machining platforms for creep-feed VIPER grinding of nickel alloys. Since 2015, NCMT has also been the Europe-wide agent for photo-activated adhesive workholding systems manufactured by Blue Photon in the US. 

NCMT has now signed an exclusive distribution agreement with Tritone Technologies, an additive manufacturing (AM) technology specialist in metal and ceramic applications. Typical AM parts will be available with representation on Stand 130 in Hall 19.

Rigid, thermally stable construction protects the Okuma Genos M560-V-e VMC from deformation, resulting in high machining performance for an entry-level machine. At the show, the 3-axis machine will be equipped with a Cellro X20 robotic.

The M560-V-e has a 1,050 by 560 by 460mm working envelope and a maximum table load of 900kg. The 15,000rpm BT40 spindle moves in the X and Z axes, with the table moving in Y. A 32-position tool magazine is provided. Software can be added, including Machining Navi to minimise chatter by finding the best cutting conditions. It employs a microphone to detect the onset of vibration and feeds information back to the control. 

The popular Genos M460-5AX VMC will also be at MACH and will be one of the first Okuma machines to be exhibited in the UK with the manufacturer’s new OSP 500 control. It was the original 5-axis machine in Okuma’s economical, series-built Genos range. The trunnion with a rotary table and 5-axis simultaneous control gives the machine the ability to produce highly complex components. The BT40 spindle is rated at 15,000rpm 22kW, which is served from a 48-position tool magazine. Features such as Okuma’s 5-axis auto-tuning system that accurately fine-tunes the geometry of the machine for ultra-high precision, and Okuma’s Absoscale linear encoders in the X, Y and Z axes, are all part of the standard specification. 

The competitively priced Genos L3000-e-MYW lathe from Okuma will be at MACH, fed automatically with shaft-type parts by a Cellro CoMate cobot. Maximum turning diameter is 300mm and the rotational speed of the 22kW spindle is up to 3,800rpm, all in a compact footprint of 2.5 by 1.9m. The turning centre has a sub-spindle and a 12-station turret with Y-axis and live tooling. 

With a 240-degree swivelling B-axis head and HSK-A63 (optionally Capto C6), 12,000rpm 22kW spindle for turning or milling components up to 1,500mm between centres, an Okuma MULTUS U3000 multi-tasking lathe will be demonstrated on the stand. The tool magazine has 40 stations as standard but is optionally available with a capacity of 80 tools. 

The machine is fitted with Okuma’s linear scales for high-accuracy positional feedback. Servo motors deliver feed rates of up to 50m/min in the X and Z axes, 40m/min in the 250mm Y-axis. Together with the C-axis on the main spindle, the machine is capable of fully interpolative, 5-axis (X, Y, Z, B, C) machining of freeform surfaces.

Next-generation Okuma control

The OSP-P500 CNC system, manufactured in-house by Okuma along with virtually everything else on its machines, will be on show for the first time in the UK. It combines highly productive and precise machining with ease of use, energy efficiency and safety features to protect against cyber-attacks. Particularly well suited to high-speed machining applications and achieving top-quality surface finishes, the CNC has twice the computing power of conventional machine control, shortening cycle times by up to 15%.

An on-machine Digital Twin facilitates high-precision simulation of machining processes, reducing set-up times and speeding production. By performing these simulations on the machine itself, production can start immediately afterwards. 

Ultra-fast 5-axis 

In a space on the shop floor of less than 3.3sq/m, the N2-5XA horizontal machining centre from Makino is capable of very high-speed machining of components up to 300mm diameter by 270mm high and weighing a maximum of 30kg, including fixtures. The machine is ideal for fully interpolative, 5-axis machining of complex components. 

Within its working volume of 300 by 300 by 230mm, the horizontal spindle design ensures that gravity assists swarf removal, prolonging tool life by avoiding the recutting of chips that are frequently harder than the parent material.

The show will also mark the first UK appearance of the Makino DA300 5-axis, trunnion-type, VMC configured as a production cell with 40 pallet positions on five levels for extended periods of lights-out running. Maximum workpiece size is 360mm diameter by 300mm tall for the eight positions on the top row of the store and 280mm tall on all other levels. Maximum payload per position is 60kg. The automation package includes an integrated chuck, pallet interface and Single Pro6 graphically-driven cell controller, via which it is easy to manage the machine and pallet system. 

Makino’s U6 H.E.A.T. Extreme wire-cut EDM centre will be on show. In addition to using standard wire from 0.1 to 0.3mm, it is optionally possible to run the largest diameter wire of any machine on the market at 0.4mm. The wire is coated and distinct from the uncoated brass wire that is commonly used in industry. 

Part of Makino’s popular U-Series wire EDM machine platform, the U6 H.E.A.T. Extreme uses Bedra copper core wire with a double-layer coating having controlled zinc donation. It has been optimised for use with Makino’s generator and is exclusive to the new machine, promoting fast cutting at a reduced wire speed, leading to lower manufacturing costs. Areas of application include aerospace and medical component machining, separating additively manufactured parts, machining tall moulds and dies and tackling tough nickel alloys.

The Makino EDAF3 die-sinking EDM machine on the stand features a rigid, precise structure and integral thermal cooling of the Y- and Z-axis cast components to ensure long-term accuracy. Table size is 700 by 500mm and the dielectric reservoir is built into the base casting of the machine to improve stability and minimise the footprint. The machine uses Makino’s latest Hyper-i control, which can be factory-ordered mounted on either the left or right, facilitating easy integration of one or more machines with a variety of commercially available electrode and work pallet handling robots. 

Exhibited on the stand will be the Blue Photon photo-activated adhesive system. The method is ideal for securing awkwardly shaped parts to allow maximum access to tools for tight-tolerance machining or inspection. The process involves applying an adhesive that is cured by ultraviolet light via an LED spot-curing system. After machining is complete, the adhesive contact points can be sheared to free the workpiece by rotating the gripper pins in the fixture plate with a spanner. The residual adhesive can subsequently be removed by the application of hot water.

FANUC to showcase new mill/turn option 

Industrial automation specialist FANUC UK will showcase a range of real-world robotic innovations at MACH 2024, including an affordable multi-axis turning and machining solution aimed at helping manufacturers in the aerospace, automotive, utilities and energy supply chains reduce cycle times, costs, save space and boost production efficiency.

As well as EDM wire cutting, aerospace cobot drilling and educational solutions, the centrepiece of the FANUC Stand 350 in Hall 6 will be an advanced ROBODRILL machine, equipped with a 24,000rpm spindle and mounted with a NIKKEN two-axis high-speed rotary table, featuring a built-in direct drive motor that achieves 1500rpm. In operation throughout the show, the demonstration cell will produce finished scroll compressor aluminium housings, showcasing the cost-saving and performance benefits to be gained from combining machining and turning processes.

“FANUC and NIKKEN have worked together to create a combined machining/turning cell with an extended range of functionality, offered at a fraction of the cost of machines with similar capabilities,” says Oliver Selby, Head of UK Sales at FANUC UK.

“At the heart of the solution is our D21LiB5ADV Plus ROBODRILL, which is a 3-axis machine in its core configuration. The NIKKEN table adds a further two axes, allowing users to turn and machine components on the same unit,” Oliver explains. “This is a real breakthrough, which brings the functionality of million-pound machines within reach of SMEs at a significantly lower cost, helping them to become more competitive and consider undertaking work that would previously have been unavailable to them.”

Less than 3m long and a little over two metres wide, the ROBODRILL/NIKKEN solution features a NIKKEN 5AX-201 tilting rotary table with pneumatic clamping, enabling difficult-to-hold components to be quickly mounted and changed. In addition, access from all sides means the majority of operations can be completed in one hit, optimising machine tool and operators’ time. 

Also available to visitors to the FANUC stand at MACH 2024 will be an aerospace drilling cell comprising a CRX-25iA cobot, a FANUC C600iC ROBOCUT wire EDM and an automated robot machine tool loader, developed in conjunction with YMT Technologies, alongside a D21MiB5ADV Plus ROBODRILL.

Finally, as part of the company’s ongoing commitment to encouraging a pipeline of new talent into engineering, manufacturing and automation, the FANUC stand will also host a turning and milling education simulator and a new-to-market ROBOT G-code solution with a FANUC Education cell. Controlled by a proprietary FANUC CNC unit, it features all the real-world functions required to teach core robotics programming and operating skills and help inspire the next generation to realise their career ambitions.

VR-supported product presentation for an extraordinary experience

McDowell Machine Tools Limited is offering an impressive view of the high-performance machine tools from WaldrichSiegen at its Stand 129 in Hall 18 at MACH 2024  this year. The turning, milling and boring specialist will be presenting a tour through a 3D machine: the high-precision vertical turning ProfiTurn V machine.

A Special Tool for Presenting Special Products

With the help of VR glasses, visitors will have the opportunity to take a unique look behind the scenes. From the inner workings of the machine to the design, 5-axis machining and automatic tool change system – the entire performance spectrum of the vertical turning machine is shown and brought to life in 3D directly at the booth.

“The dimensions of our products make an impressive and comprehensive presentation at a trade fair very difficult. Conventional media such as brochures or videos certainly provide some impressions – with virtual reality, however, it is possible to experience and present our products at close range,” explains Dr. Thorsten Mehlhorn, President & CSO of all HerkulesGroup companies. “Experiencing our impressive products at trade fairs and events creates a better understanding for our customers and enables us as a manufacturer to respond even more specifically to their requirements and problems,” Dr. Mehlhorn continues.

First-Class Machining System for British Steel Producer

Sheffield Forgemasters has entered into a long-term partnership with leading machine tool supplier WaldrichSiegen for lifetime support of its planned new machining facility. WaldrichSiegen will provide a ten-year contract for the full lifecycle and production support, design, supply, manufacture, installation and commissioning of 17 new machine tools that will produce high-precision, complex shapes for ultra-large steel castings and forgings.

The machining line will be installed in a new production facility at the Brightside Lane site and will include a series of large 5-axis vertical turning lathes, part of a recapitalisation investment of up to £400 million over ten years.

Dr. Thorsten Mehlhorn says: “We are immensely excited to be partnering with Sheffield Forgemasters and are proud to be their choice for this groundbreaking project as the company expands its capabilities in the manufacture of highly complex forgings and castings. This partnership is based on the principle of lifetime support and will produce the most advanced facility of its kind in the UK!”

The entire machine line-up includes seven heavy-duty ProfiTurn V Vertical Turning Lathes with table diameters from 5 to 8m, which will significantly shorten machining times for complex components and increase performance levels and production management on site.

The ProfiTurn V – Powerful Vertical Turning Machine for Special Requirements

Based on tradition and many years of experience in the construction of horizontal turning machines and portal milling machines, WaldrichSiegen is now setting new standards in the market with a new innovative machine concept. The ProfiTurn V vertical turning machine is characterised by precision, efficiency and reliability.

Features that clearly set the ProfiTurn V lathe apart from other concepts on the market are a significant increase in the precision and performance of this innovative vertical turning concept. The ability to integrate different technologies allows highly flexible machining of complex workpieces. The fully hydrostatic design in all main axes guarantees maximum cutting performance and accuracy.

The ProfiTurn V is also characterised by its energy efficiency and ease of maintenance. In conjunction with the fact that all machine components are of high quality ‘Made in Germany’, these vertical turning machines guarantee high productivity and minimised life cycle costs.

🎧- Versatile workholding ensures productivity and precision

TecnAir designs and manufactures an extensive variety of pneumatic cylinders, valve assemblies, linear drives, handling equipment, controls and other products. Located in Shipley, the company’s products are used for the assembly of standard and special automation solutions worldwide, predominantly in the transport, semiconductor, railway, marine and off-shore automotive industries. 

Characterising this activity above all else is the large amount of metal cutting involved in machining the parts, as well as the extreme accuracy to which they must be machined. To this end, since the early 2000s the manufacturer has entrusted component clamping on its machining centres to Chick workholding products, manufactured in the US and supplied through sole UK agent 1st Machine Tool Accessories. 

Steve Watson, CNC Operations Manager at TecnAir advised: “The accuracy of the sliding surfaces is critical on many of our components, so tolerances down to single-figure microns must be held to ensure they can perform many millions of cycles faultlessly. Similarly, the finish on ground, polished or roller-burnished sealing faces has to be very high, so the flatness and roughness of milled surfaces must be excellent to allow the low Ra values to be achieved as quickly as possible.”

“Fixturing is crucial, as any movement or vibration cannot be tolerated. Chick products have underpinned the required level of accuracy in our factory for the past couple of decades and continue to do so. Not only is rigid workholding ensured, which incidentally also prolongs tool life, but a high level of interchangeability of the various Chick clamping units also helps to minimise investment in the equipment.”

Monthly quantities are machined in batches of from 200 to 2,000 for TecnAir’s products, which account for 80% of turnover. Many thousands of component variants are involved, which are manufactured over a double shift pattern, five days a week plus at weekends if necessary. The remainder of throughput is subcontract design and production of parts for other companies, which involves machining anything from one-offs to a couple of hundred components.

Supporting the prismatic machining operations on the shop floor are 15 Chick QwikLOK units, which are used on five vertical machining centres (VMCs), three from HAAS and two from Yamazaki Mazak. Six of the units are dedicated to pendulum machining of relatively short pneumatic cylinder bodies from aluminium extrusion in three operations – rear-end cap machining, front-end cap machining and inlet and outlet port machining on a Mazak VTC-530. The resulting high-density workholding has the effect of maximising the use of the available machining area and reducing the overall number of tool changes needed for machining the components.

In addition, there are 11 MultiLOK towers deployed across three twin-pallet, 4-axis, horizontal machining centres (HMCs). They are a stand-alone Doosan HC400 and two Mazak HCN-4000s linked by a Palletech automated storage and retrieval system for 16 machine pallets. Materials processed are mainly aluminium and stainless steel, plus some brass, with castings accounting for 30% of throughput while the remainder is produced from either billet or extrusion.

The QwikLOKs use three jaws to secure two workpieces simultaneously against a fixed central jaw by turning a single handle, in contrast to a traditional vice that is only able to clamp a single part. Opposing forces are cancelled and a reliable reference point is provided for machining. The Chick jaws create a pull-down action when they close, ensuring rigid workholding. On every face of each four-sided MultiLOK tower, according to the size of the component to be fixtured, there is either a single-station or a dual-station jaw set. These employ Chick’s proprietary QwikChange snap-on/snap-off interface. Round and diamond pins in two bushed locating holes provide high clamping repeatability, leading to consistency of machining from one batch to the next.

Ideally, for maximum productivity and extended periods of unattended machining, components are set up on all four faces of a Multi-Lok. However, there are occasions when only two or three faces are employed, such as if components are longer than the tower width and overhang one or both sides.

Alternatively, instead of a jaw set, an aluminium faceplate can be snapped in seconds onto the QwikChange interface on any side of the towers. The repeatability of location is within microns, providing what is essentially a zero-point pallet exchange system. The faceplate is pre-machined and may incorporate other workholding devices to configure bespoke fixturing arrangements for securing awkwardly shaped and/or multiple components quickly in a single set-up. 

The decision to invest in a faceplate depends on the number of components to be produced and the frequency with which batches repeat. At TecnAir, a couple of dozen machined faceplates are stored for suitable jobs. An additional advantage of this approach is that workpieces can be fixtured offline, away from the machine tool, maximising its spindle uptime. 

It is similarly possible to put a faceplate onto a QwikLOK on a VMC if an application warrants it. Moreover, based on similar considerations regarding quantities of components involved and frequency of production, bespoke machined soft jaws can be held for use on the QwikLOKs to hold securely workpieces of difficult shape, often in multiples, such as round components that would tend to spin in a normal hard jaw set.

Mitutoyo to showcase automation and new CMM 

Celebrating 90 years of innovation, Mitutoyo will exhibit a range of metrology solutions at this year’s MACH show at the NEC in Birmingham on Stand 418 in Hall 18. Launching a new CMM alongside metrology automation within a production environment, industry specialists and live demonstrations will be available throughout the week.

Lantek brings ‘Expert’ suite to ‘Nest’ at MACH

Lantek, the specialist in sheet metal CAD/CAM and ERP software will be exhibiting its latest software at MACH 2024 in Hall 17 Stand 319 from 15th to 19th April.

Flexibility is one of the major improvements in Lantek Expert, making it easy to move nests of parts between different machines as production requirements dynamically change without the need for manual adjustments. New is the Assembly 2 Nesting software. Here, customers can import a complete 3D model assembly of parts. These are individually sorted and unfolded in the Lantek software, nested and then cut in the shortest possible time, without the user needing their own CAD system to do 3D model manipulation.

For tube and pipe work, Lantek Flex3D has seen some fundamental changes which reduce execution times. The software also helps eliminate collisions through hole destruction technology and aims for a ‘no scrap’ target with micro joints connecting parts to use up every bit of the tube material.

Lantek’s Machine Connectivity makes it possible to directly connect to different machines, gathering information from the machine automatically. This data is fed into the Lantek Control Panel app which provides a cloud-based interface to monitor the cutting machine state irrespective of its type or technology, without operator intervention, in real-time. The app can be accessed on a tablet or mobile device so that the collected and merged data can be viewed by managers giving them a real-time overview of the complete production process and manufacturing facility. The app also displays utilisation rates so that free capacity can be allocated and, gives warnings when unexpected events occur, so that remedial action can be taken without delay.

Adam Ball, Solutions Sales Manager for Lantek UK says: “This technology is particularly useful for companies that use a mix of different cutting technologies such as punching, laser or waterjet from different manufacturers. The real-time feedback will lead to significant productivity improvements, avoiding errors, and cost overruns and will optimise the use of available machine capacity.”

Lantek Integra ERP

The power of the Lantek software is in the way in which it is integrated into the overall manufacturing and management processes within a sheet metal company. Accurate and fast quotations directly impact the levels of business won. Lantek has the tools to minimise the work involved in creating quotations, using stored, calculated and historic data on material prices, operation times and material usage with products including iQuoting, Assembly 2 Nest and Lantek Expert. 

During production, Lantek Integra products including Lantek MES and Lantek WOS keep track of and monitor stock levels, material availability, capacity, delivery times and costs against targets, optimising the efficiency of the manufacturing process. The new Machine Connectivity tools further increase the accuracy, efficiency and automation of every aspect of this process. 

Over 35 years of development have been put into optimising the software to exactly suit sheet metal manufacture, giving Lantek the skills, knowledge and capability to maximise the efficiency and profitability of manufacturers.

Southern Manufacturing returns next month

From 6th to 8th February 2024, thousands of visitors will stream through the doors of the Farnborough International Exhibition & Conference Centre, where once again Southern Manufacturing & Electronics will host hundreds of firms offering products and services to manufacturers from all over the UK, Ireland and beyond. It is one of the most important and comprehensive engineering trade fairs in the calendar and the forthcoming show will set the record for the largest ever number of overseas exhibitors.

Since it all started in 1997 as a small, regional event, this annual celebration of all things engineering – both mechanical and electronic has grown into an expo of international importance, attracting exhibitors from all over the world. An interesting facet of the way the show is laid out is that, although the various technologies and industries covered are diverse, there are no physical barriers between the areas. This allows cross-over between the different engineering disciplines. Visitors say this is one of the show’s main attractions, as it often leads to the discovery of companies that would not normally be found. Technology Trails grouping firms having expertise in particular areas help to guide visitors around the aisles.

The event attracts big-name manufacturers, but it is also very accessible to SMEs. The show organisers operate a policy of open access, discouraging larger firms from dominating the space. The mixture of firms of various sizes operating in different disciplines gives the show a vibrant atmosphere that encourages an exchange of ideas and forges long-term business relationships. 

For visitors, it is the ideal venue to address multiple purchasing requirements quickly. It is the place to see all the latest in machine tools, tooling and workholding, additive manufacturing options and related consumables, plus test, measurement and inspection equipment. There will be companies selling these solutions and others already operating them that will be offering an extensive range of subcontract manufacturing services.

Mechanical, electrical, electronic, electro-mechanical, hydraulic and pneumatic components, assemblies and technologies will be everywhere. A myriad of firms will offer plastic injection and rubber mouldings, sensors, drives, rotary encoders and linear scales, fasteners, pressings, wire forms, springs, gaskets, and more. Other items to be promoted will encompass business and manufacturing software, production and planning aids, oil and coolant supply, waste removal and recycling, and freight services. To maintain high standards of cleanliness and order in factories, other companies will have equipment for dust and fume extraction and humidity control, and there will be workplace storage systems, bespoke case and foam manufacture and plastic packaging to keep things tidy.

Automation will be prevalent, driven by a skills shortage across Britain and indeed the whole of Europe. Manufacturing is struggling to recover from problems caused by Covid, supply chain disruptions, soaring energy costs and higher taxation. Consequently, many exhibitors will be showing solutions that will raise profitability and lower costs, such as Industry 4.0, end-to-end digitalisation, robot and cobot machine tending and other types of automation. Additionally, there will be renewed interest in the reshoring of production.

Alongside the exhibition and demonstration areas, there will be a programme of free technical seminars. The seminars will give visitors and exhibitors alike valuable learning opportunities, with a particular focus on the technical, managerial and environmental issues facing manufacturers today. Presentations will include advice for small manufacturers looking to improve their relationship with customers, how to enhance a sales team’s performance, CE and UKCA marking compliance, digital process management, sustainable practices in manufacturing, and skills training.

Southern Manufacturing & Electronics co-locates every year with AutoAero, a specialist theme within the exhibition devoted to aerospace and automotive engineering. Admission is free of charge.

🎧 FGP Turbo’s through complex work with Mastercam

Made up of three main companies, the FGP Group is a specialist Tier 1 subcontractor that provides services from design and manufacturing to surface coating, heat treatment, assembly, inspection, testing and more. As one of the three companies in the group, FGP Systems Ltd typically produces prismatic components for the aerospace industry – it is here that the company utilises Mastercam CAM software. 

Founded more than 45 years ago, the company bought      its first 5-axis machine, a DMG MORI DMU 50 eVolution   over   20 years ago – and 3 and 5-axis machining has since become the backbone of the Yeovil-based business. The company produces a vast array of components for aircraft and helicopters such as valve bodies, actuation parts and service components – with complex turbines increasingly becoming the mainstay of production on the shop floor.

Simon Griffiths-Hughes from FGP Systems Ltd says: “If we look back over 20 years ago, we had to stay competitive and to do that back then, the buzzword was 5-axis machining. We knew that was the future, so we decided to buy our first 5-axis machine. Our work is five-sided prismatic machining and we needed 5-axis machines to accommodate that. Since then, we have taken on more work like turbines – now we do a lot of turbines in various shapes and sizes.”

Discussing the complexities of machining turbines, Simon continues: “The complexity lies within the programming. A turbine, depending on its complexity has main blades and multiple splitter blades. This requires a lot of programming time and you must have safe and repeatable programming and machining strategies. To support what was the new 5-axis investment 20 years ago, we needed a CAM package to support that, and we chose Mastercam. We did our due diligence and went through a couple of CAM providers, but Mastercam were offering the full support we needed for full simultaneous 5-axis machining. We took the plunge straight into full simultaneous 5-axis machining from the off, and Mastercam was able to support us through that period.”

Alluding to the challenge of taking on both 5-axis machining and a new CAM system, Simon says: “At the time, we just had to get on with it, but the support from machine tool provider and Mastercam seemed to work very well – and this has grown with us as we have added to that portfolio of machines. We now have 15 5-axis machines with a total of 63 CNC machines across two sites, business has grown considerably down the years.”

Looking at how the workload has changed at Somerset-based FGP Systems Ltd, Simon adds: “If we look back 10 years ago, a customer came to us with the need to machine turbines of all different sizes and types. This ranged from scroll turbines and progressed to axial fans. The majority of those turbines at the time were cast and we were very keen to go to a billet solution, which makes it easier for us to start the process. The raw material yield from the casting is notoriously bad and if we go to billet form, it is far easier for us to work on that immediately to get a better yield and reduce cycle times. Once we machine the turbines, we can test them on-site with a spin test of over 100,000rpm.”

For the parts to perform, they have to be manufactured with impeccable precision. As Simon adds: “To get these turbines up to speed, they have to be balanced to within micrograms. If you look at a cast variant, it is very difficult and time-consuming to manufacture and balance with precision. The machining strategies we use on our CAM package, enable us to create a machining solution for titanium or aluminium turbines – and then migrate that solution across to the next turbine. The quality of our turbines is a cornerstone of what FGP Systems is about, and the CAM solution and machining strategies help with this.”

“Since we on-boarded ‘blade expert’ through Mastercam, that has taken our off-line programming time down from multiple days or even multiple weeks for complex multi-splitter turbines, down to just an afternoon’s work. It really is that simple to use. What this gives our business is improved turnaround times. The customers are always demanding shorter and shorter lead times. If we can off-line program a turbine in an afternoon rather than a couple of days – that is perfect for our business,” concludes Simon. 

🎧 Ready for ‘Lift-off’ with OPEN MIND

As the name would suggest, Hill Helicopters is a manufacturer of luxury light helicopters. Since its inception, the company has been on a fascinating journey that is seeing the team of 80+ engineers develop and manufacture a complete aircraft from the ground up. To achieve this, the Rugeley manufacturer has enlisted the support of leading manufacturers from the sphere of machine tools, cutting tools and ancillary equipment. When the company needed industry-leading CAD/CAM technology that is trusted by the aerospace industry, it turned to OPEN MIND Technologies and its groundbreaking hyperMILL CAM suite.

Discussing the foundation blocks of the Staffordshire manufacturer, Company Founder, Chairman and Chief Engineer at Hill Helicopters, Dr Jason Hill says: “Hill Helicopters are designers, developers and manufacturers of the HX50 5-seat turbine light helicopter. We are actually bringing light helicopter manufacturing back to the UK for the first time in 50 years. To sell an effective general aviation light helicopter, you really have to match the price point with high-end supercars. To do that, you really can’t turn to the existing aerospace supply chain. So, we’ve had to develop a vertically integrated manufacturing strategy where we manufacture everything in-house from scratch.”

Commenting on how the company has achieved this, Dr Jason Hill adds: “We have developed the entire machining capability and the whole composite capability – for a whole aircraft, transmission system and the gas turbine engine. That has been an enormous undertaking. We have a group of technology partners that have essentially helped us to drag ourselves up the learning curve. This has enabled us to physically machine parts, cast parts and make composite components. OPEN MIND Technologies and hyperMILL have been an instrumental knowledge and support partner in enabling us to program and manufacture complex machined components in a wide variety of materials.”

Discussing the start of the relationship between Hill Helicopters and OPEN MIND Technologies UK, Justin Talboys-Cotton from OPEN MIND Technologies UK says: “We were initially invited by Hill Helicopters to look at their compressor wheel, which is effectively an impeller. It was a very challenging component with very small gaps. It was a challenge they gave us, but from that point on, there has been a wide variety of parts the company wants to make. From there, the relationship has grown and as Hill Helicopters have bought more equipment and machine tools, they have increased their usage of hyperMILL. Being invited into Hill helicopters at such an early stage – before machines and programmers were here, it has been really exciting to be part of this helicopter development programme and watching it grow.”

The company is fast approaching 1,000 sales with 943 aircraft pre-ordered for delivery to 67 countries at present. It is currently looking to invest in a new facility to accommodate its growth, and every month new milestones are being reached in bringing the project to rapid fruition. Hill Helicopters has pioneered a new approach to delivering and supporting safe, exciting luxury private aircraft ownership at an affordable price, calling the new concept ‘General Aviation 2.0’. General Aviation 2.0 (GA 2.0) is what Hill Helicopters calls an ‘end-to-end ownership experience’ that is entirely customer-focused. 

It begins with a ground-up modern aircraft design while simultaneously meeting or exceeding the latest EASA and FAA airworthiness requirements. Beyond this, GA 2.0 also provides an all-new, safe and fully supported ownership experience. These factors ensure the new aircraft delivers low operating costs and maintains a stable high resale value, making personal helicopter ownership more attainable than ever before. As an aircraft, the Hill GT50 engine is a 400hp unit with a take-off power of 440hp to 10,000ft, a cruise speed of 140kts and a maximum range of 700nm. The company is also manufacturing a commercial variant, the HC50. The differences between the HC50 and HX50 are price, time to market and customer participation in the HX50 manufacture.  

Commenting upon the current stage of development, Dr Jason Hill says: “Fundamentally, at this stage, our sole objective is to get through the development of parts and sub-systems as fast as possible. Pretty much everything we do on every single machine here is a first-off, a one-off. So, we must manage the risk of programmer error or machine crashes as we are going through these development phases at pace. The Virtual Machine capability within OPEN MIND is absolutely crucial to us being able to do that with minimum risk and the maximum confidence possible – as quickly as possible.”

Justin Talboys-Cotton from OPEN MIND adds: “Virtual Machine optimiser on the gantry mill is ensuring that the customer covers things like rewinding automatically. As a programmer, this means you program as normal even though the machine is complex. Having the hyperMILL Digital Twin set up and Optimizer, we automatically ensure the processes are collision-free and it can run within the machining envelope comfortably. I believe the main aim here in regards to being efficient, is managing lots of parts and lots of design changes that are involved with the components passing through the process chain for the first time. hyperMILL is enabling Hill Helicopters to really optimise their programs, first of all as prove-out for ‘fit for function’ but also to make sure the parts are going to be valid for the production environment as well.”

Adding to this, Dr Jason Hill comments: “We program milling and turning with hyperMILL and it is absolutely instrumental for us to be able to rapidly develop literally, hundreds of complex components in a wide variety of materials to extremely tight tolerances.”

Concluding on the project, Dr Jason Hill says: “I have been dreaming about making this helicopter since I was a little boy, so to find myself 44 years later in a position where this thing is becoming physical and becoming real, where we are not far from actually flying – it is an amazing experience. I think the day-to-day requirements of building a helicopter and a jet engine from scratch is extremely demanding. However, seeing the joy in our staff and our 943 customers who are seeing this thing become real and taking its first baby steps into flight, more than offset that. It’s a journey that has definitely been worth it.”

🎧 Cutting the chatter

Productive Machines is on a mission to provide a 15-minute turnaround from receiving data on its cloud-based, artificial intelligence platform to delivering a click-and-play machining protocol that enables manufacturers to machine the best part, faster, first time. John Yates talks to the spin-out team whose software-as-a-service is driving step changes in productivity and sustainability.

Walking along the second-floor corridor to the Productive Machines’ workspace in the AMP Technology Centre, Rotherham, Dr Erdem Ozturk stops to look through the window at the Rolls-Royce Factory of the Future, whose 3,000sq/m of machining workshops were his research and development laboratory for more than a decade.

Erdem led the Advanced Manufacturing Research Centre’s brilliant Machining Dynamics Technology Group, which grew in the innovation environment enabled by Dr Sam Turner and AMRC co-founder Professor Keith Ridgway which propelled the Factory of the Future to global leader in aerospace milling.

Their success was achieved by adapting and refining the fiendishly complex mathematical models of machining research pioneers like Franz Koenigsberger and Jiri Tlusty whose ideas were turned into game-changing operational manufacturing methods by their former students, and now professors in their own right, Yusuf Altintas, Scott Smith and Tom Delio.

Perhaps the AMRC’s biggest success came in 2014 when they applied these theoretical models to vibration control, cutting tool design, and residual stress management in a SAMULET project that was to revolutionise the manufacturing of Rolls-Royce aero-engine discs and shaft components. 

The improvements in quality, alongside the time and cost savings achieved in the manufacture of the fan disc, have become folklore in the AMRC and the close-knit aerospace manufacturing community: a 50% reduction in cycle times and right-first-time production rates rising from 85% to over 99%. Coupled with cost-savings of £135m, this made UK jet engine production globally competitive, safeguarding 400 high-value-added jobs and unlocking a £300m investment in a North East plant.

Not content with this success, Erdem and his AMRC team, along with European partners, began harnessing the power of information technology to push the boundaries of the possible, creating state-of-the-art digital twins that combined machine tool dynamics, control loops, tool-path generation and machining processes, to boost productivity, extend tool life and eliminate chatter.

Productive Machines traces its lineage back to this remarkable pedigree. Formed in 2021, shortly before joining an elite group of start-ups on the ATI Boeing Accelerator programme – over 200 applicants from 44 countries were whittled down to just ten – the business was explicit from the start in its mission to maximise the productivity and sustainability of machine tools. 

“We are using our unique digital twin to simulate millions of combinations of machine settings to arrive at the optimum feed rate and spindle speed settings for a given process before manufacturing. This eliminates chatter vibrations and provides machining optimisation, preventative maintenance and part quality that may not be achieved by a human operator even with years of continuous improvement,” says Erdem, who now leads a growing international team of machining physics developers and software engineers from their base in the heart of South Yorkshire’s Advanced Manufacturing Innovation District.

Having raised a cumulative £3m investment, the company launched its Feed Rate Calculator and Spindle Speed Calculator apps in October and November last year respectively. This was followed by an early access programme for a predictive maintenance service for spindle health monitoring in December. 

In the next few months, they will be launching the fully automated cloud based system that achieves a 15-minute turnaround from receiving data on its artificial intelligence platform to delivering a click-and-play machining protocol that enables manufacturers to machine the best part, faster, first time.

“We saw there was a massive opportunity to turn our cutting-edge technology into a simple, straightforward Software as a Service (SaaS) product,” Erdem adds. “Using artificial intelligence and digital twins of the milling process, we can identify vibration-free parameters and automatically personalise the process to eliminate chatter. This opens up a future where cutting optimisation technology is accessible to all, regardless of the scale of operation”

One early client, Yorkshire headquartered Ficep UK, a leading supplier of structural steel and plate fabrication machine tools, has seen process productivity increase by 110%, with cycle times cut by 53% while reducing the magnitude of vibrations five times.

Other clients report reductions in machining design and set-up times of 20%; cycle times reduced between ten to more than 50%; operational and maintenance costs cut by 25%; and cutting tool costs reduced by 11% 

An additional benefit of this software-as-a-service is the way it can dramatically reduce manufacturers’ carbon footprint. “By finally solving the age-old and frustrating problem of machine tool chatter, we calculate that our technology could save a staggering 2.5 gigatonnes of carbon dioxide emissions between now and 2050,” Erdem says. To put this into perspective, 2.5 gigatonnes is equivalent to the UK’s total carbon emissions – every factory, fire, car, flight and light – for six years.

While work continues in developing and refining the AI platform for launch in the spring, it’s fascinating to learn that an essential piece of kit in this operation is one of the oldest in the toolbox: the tap test. Used in aerospace engineering since the 1950s, the tap test relies on simple physics: the kinetic impulse of a hammer strike dissipated as vibration and sound. 

However, where traditional tap testing relied on skilled individuals to interpret the sounds made by the struck object, such as a machine tool, today’s digital tap tests are much more sophisticated and precise. Instead of transmitting vibration responses to the ear as an acoustic sound wave, a digital tap hammer sends the vibration response as data to a computer for recording and analysis.

Specialist software then calculates the precise frequency response from those vibrations, considering parameters like the frequency, amplitude, and decay rate of the vibrations, and enables an exact analysis of that tool’s unique characteristics and condition. 

From its origins, the age-old practice of tap testing has not only endured but has evolved into an even more powerful tool in the era of smart manufacturing, becoming a critical component of quality control, material characterisation, structural health monitoring.

“Digital tap testing, enhanced by AI, is ushering in a new era of precision and efficiency in manufacturing. It empowers manufacturers to optimise machine tool performance, reduce waste, and enhance product quality. It is democratising condition-monitoring and predictive maintenance, enabling even small-scale operators to benefit from data-driven technologies without costly investments in sensors or infrastructure,” Erdem added.

Although focused on the future, Erdem is also a keen student of machining history and one of his go-to authors is the American Quaker Frederick Taylor, best known for bringing the ‘scientific method’ to the early factory system making it more efficient and productive. 

Taylor also wrote a book On the Art of Cutting Metals, published in 1907, which identified “chatter as the most obscure and delicate of all problems facing the machinist – probably no rules or formulae can be devised which will accurately guide the machinist in taking maximum cuts and speeds possible without producing chatter.”

Erdem smiles and says Taylor was absolutely right. “There were no formulae available to predict chatter vibrations until 1954 when Tlusty was able to formulate the absolute stability limit for chip width for turning operations. That meant if the process planner selected a chip width smaller than this limit, the process would be stable and there would not be chatter vibrations irrespective of the spindle speed used.”

Seventy years on since the formulation of Tlusty’s law for the identification of chatter stability lobes in turning processes, the Productive Machines team are coming very close to proving Frederick Taylor wrong by accurately guiding the machinist in making maximum cuts and speeds possible without producing chatter for machining processes. 

That, I suspect, matters as much to this team as turning a profit. 

It would certainly delight Keith Ridgway: “If I were starting the AMRC today, it would not be by constructing a huge machining research facility. It would be by harnessing the power of artificial intelligence, cloud-based data analytics and digital twins. Productive Machines are blazing that trail today from a small office on the very site where we set out on our journey.”

CERATIZIT adds more value 

Addmore Engineering Ltd supplies high-precision parts to the automotive, medical, oil and gas industries, and what started from a barn in Watford is now a company that employs 48 skilled machinists and runs 24 hours a day.  

Frank Vasquez started the Bedford company decades ago with two sliding-head machines, quickly building a solid reputation for the high-precision parts he was producing. Specialising in highly precise and intricately machined parts, Addmore turned to CERATIZIT over 20 years ago to help with their complex component and tooling needs. Regularly visited by an Applications Sales Engineer and a Technical Sales Engineer from CERATIZIT, a strong working relationship has been built over the years, which has had a profoundly positive impact. 

Whilst many of CERATIZIT’s inserts have been used by the company for such a long time that they have become machining staples, a recent switch to CERATIZIT’s Pentron Drill was made to increase tool life and save money on tool-replacement costs. The tool Addmore were using previously was the 2XD 46mm diameter C900 from CERATIZIT. Although this tool was completing the job, the inserts were getting pick-up and sticking to chips. After adjusting the cutting data to try and solve these problems, CERATIZIT suggested that Addmore try a Pentron drill on this machine. 

Immediate benefits were seen from using CERATIZIT’s 2XD 46mm KUB Pentron drill. Whereas the previous drill had an insert life of between 55 to 75 parts per edge, the Pentron drill increased this to 120+ parts per edge, an improvement of more than 50%. Shaun Thornton, Technical Manager for CERATIZIT UK, explains that: “This improvement is down to CERATIZIT’s SOGX 03 geometry and BK8430 coating in combination with the Pentron Drill. This specialist coating minimises chip-sticking and increases swarf evacuation due to its optimised flutes.”

As well as the cost-saving benefits which come from the extended insert life of the Pentron drill, switching to this insert also meant that machine cycle time was reduced by 10%, allowing for more parts to be machined per day. Addmore also has CERATIZIT vending machines on-site that allow them to access new tools as and when needed. This enables 24-hour access to tooling and parts to prevent machine stoppages.  

As a family business, Ben Vasquez joined the company when he was 17 years old and has since gained the same level of expertise that his father was known for. Once Frank stepped down as Managing Director, Ben took over his role and has been running Addmore ever since.  

Ben says: “I don’t want to look through a brochure and guess what the best solution would be. I want to talk to someone who understands what I need and recommends to me, then and there, the right tool for the job. This is where Drew and Warren have been outstanding. I know I can pick up the phone and speak to them if I have any problems. If these problems require tooling to solve them, then these are delivered the next day.”  

As a company that is growing, the future looks bright for Addmore Engineering Ltd. With 42 CNC machines, many of which are running 24 hours a day, the company continues to carry out the work that was started decades ago by Frank Vasques. Honouring his legacy, and even though Addmore is now a significantly larger operation than what Frank started with two machines in an old barn, it is clear to see that a passion for precision still goes into every part that is machined.

🎧 Innovation never stops 

Where Innovation Never Stops! is the slogan that appears on the walls of the production facilities at ISCAR headquarters and has been synonymous with the company for several decades. The Covid-19 pandemic did not interrupt the innovation process, and between 2020-2021 ISCAR introduced the NEOLOGIQ marketing campaign comprised of advanced cutting tools and tooling solutions for modern metalworking. 

Significant changes in manufacturing, such as intensive digitising, the shift to electric drive in the automotive industry, and growing precise workpiece fabrication, have emerged with new demands for cutting tools. Notwithstanding, the accelerated pace of changes sharpens the demands and requires more ISCAR NEOLOGIQ products that answer to modern-age machining. 

The CHAM-IQ-DRILL family of assembled drills that mount exchangeable carbide heads, is now upgraded with new heads in the diameter range of 33 to 40mm. These heads can be mounted on any drill possessing the appropriate pocket size. The main feature of the new heads is a multifunctional cutting geometry, which enables effective drilling of various materials such as steel, stainless steel, heat-resistant special alloys, and titanium – assuring hole precision within IT10-IT9 accuracy grades. 

The ISCAR LOGIQ-3-CHAM is also based on the concept of exchangeable carbide heads with 3 flutes for improved productivity. This is now supplemented by new carbide heads for achieving a nearly flat bottom hole. Flat bottom holes are necessary for screw head sockets, spring seats, washer ports and more. The heads ensure drilling up to an 8XD ratio without a pre-hole. The new design facilitates generating holes with a nearly flat bottom by use of a single pass. The heads are mounted on existing LOGIQ-3-CHAM tools that significantly expand the application range of the family and reduce inventory costs.

So, how do you increase the drilling depth? Use a longer drill? 

The MODUDRILL family of modular drills with replaceable carbide heads carry indexable inserts and provide an alternative solution. Mounting an exchangeable extension holder on a drill body increases the drilling depth by an additional 200mm when machining holes in a diameter range of 33 to 40mm.

Key aspects in turning

A modular tool concept is the way to reach high versatility. NEOSWISS is a new tool system with quick-change heads that follows this concept. The system is suitable for turning, parting, grooving, and threading applications. By use of a high-clamping-force mechanism, the heads are mounted on a toolholder. The mechanism provides an accurate cutting-edge position each time and utilises high-position repeatability. The system intended mainly for Swiss-type machines enables the removal of heads and replacement inserts within the tight confines of CNC machining centres.

ISCAR has developed a new lever dual lock securing mechanism for improved clamping rigidity intended for ISO turning inserts. The new design, referred to as the 

The LOGIQ-F-GRIP features a new highly advanced tool family for parting solutions. The central component is a robust tool block that mounts on a 4-pocket adapter. There are cases when the rib, a reinforcement element of the block, interferes and prevents clamping the block on typical turret positions. NEOLOGIQ overcomes this problem by providing additional blocks with the rib placed on the alternative side of the block. The revolutionary LOGIQ-F-GRIP parting system was designed to achieve extra stability and vibration-resistant high-productivity parting and grooving operations. The highly engineered LOGIQFGRIP is an assembled tool block that comprises a durable holder and a high-stiffness quad blade with pockets for mounting inserts.

The NEODO S890 is a family of 90° indexable face mills for rough and semi-finishing operations. The mills mount durable square double-sided inserts with 8 cutting edges. NEODO S890 facilitates face and square shoulder milling while providing an additional option for milling close to shoulders where there are workpieces or work holding fixture constraints. ISCAR customers have requested additional corner radii and tool diameters, therefore, this tool family was expanded with additional pressed-to-size inserts with a 0.8 mm corner radius and cutters in diameters 32 and 25mm including endmill design configurations.

Upgrading toolholders

The ISCAR SPINJET family of coolant-driven high-speed compact spindles for small-diameter tools is intended to upgrade existing machines to high-speed performers. It is now supplemented with the Micro 90 intended for miniature rotating tools in milling, drilling, countersinking, thread milling, engraving, chamfering and deburring operations. Micro 90, made of a solid titanium shell and assembled from only six parts, enables rotating velocities that range from 35000 to 53000rpm while the main machine spindle remains idle.

The chuck thickness is a factor that limits the working space of a tool. This factor often causes an increase in the tool overhang to reach a machined surface. A novelty in X-STREAM, a family of thermal shrink toolholders, is a series of slim design chucks to eliminate such a restriction. The new chucks follow ISCAR’s coolant jet channel technology providing direct coolant supply to the tool cutting edge.

Changes in metalworking technology place new demands on cutting tools. To meet these demands, cutting tool manufacturers develop new products to ensure increased performance. The industries’ response to the products sprouts new requirements.

🎧 Toolmaker dives into cost savings with Guhring

As a family-run business, Canterbury Tools Ltd has been involved in the design and manufacture of press tools since it was established almost 50 years ago. To optimise the production of specialist press tools, the Wallsall subcontract manufacturer utilises wire EDM machines from Sodick, machine tools from Hurco and cutting tools supplied by Birmingham-based Guhring.  

The West Midlands manufacturer specialises in the production of single operation tools, progression tools, transfer tools, as well as components and assemblies for automated and robotic processes in sectors as diverse as the agricultural and construction industries through to the medical, IT, aerospace and automotive sectors. To retain an industry-leading position, the ISO: 9001 manufacturer is always looking for opportunities to accelerate performance and productivity – and it is this determination to succeed that led the company to Guhring. 

At Canterbury Tools, the company utilises a selection of 3-axis machines from small capacity to 3m bed machines as well as simultaneous 5-axis machining. Discussing the daily operation of the business, Josh Bennett, the Operations Team Leader at Canterbury Tools says: “We pride ourselves on manufacturing high-quality press tooling and this includes everything from single operation to progression tools and small fine blanking work to automotive tooling. Press tools can be quite complicated projects, so we use a lot of different machine tools – and as technology has advanced, what was once done on manual machine tools is now moved to CNC machines.”

The company machines a lot of challenging materials that can rapidly erode tool life and profit margins if the correct tools are not selected. Alluding to this, Josh says: “We take massive pride in what we use in terms of cutting tools, as we have to cut very tough material daily. This means the tool life does make a difference. We do not cut materials like your everyday mild steel and aluminium where you can get away with using the same tools for a long time. When you are cutting things like D2 tool steel and running intricate forms with a high material removal rate, you really can burn through tools quite quickly.”

Alluding to how Canterbury Tools founded its relationship with Guhring, Josh continues: “We were introduced to Guhring at the MACH 2022 exhibition. We have always prided ourselves on being at the forefront when it comes to cutting tools. It is an ever-evolving industry, so you have to keep up with the technology. When we spoke to Guhring at MACH, they made promises that we have heard from many other cutting tool companies in the past. Guhring told us things like ‘We will improve your tool life’, ‘We’ll cut your tooling costs’ and ‘We’ll improve your material removal rates’. At the time, we were in the market to improve upon what we were doing and we thought we were already using very good cutters – but as always, were open to be proven wrong.”

Proving a Point

Discussing the first tool that Canterbury used from Guhring, Josh continues: “The first Guhring tool was the Diver Series of end mills. Guhring told us that it was the ideal tool for our applications and everyday use. We trialled the Guhring Diver against the tools we were using at the time. To our surprise, they annihilated the performance of the apparently high-end tooling that we were using at the time.”

“We found a 3X increase in performance compared to what our existing tools were doing. This was a massive surprise to our management team, the accountants who deal with the daily costs of our business and most importantly to the machinists on the shop floor. The machinists really saw a difference in what they were doing every single day with the new cutting tools. From this point, we took Guhring seriously and really put their tools through some rigorous testing. From the testing, we saw a threefold increase in our tool life when we ran at the same speeds and feeds as our old cutters. With help from Guhring, their Navigator system and their engineers, we honed our skillset and started to use this skill to push the cutters to within an inch of their lives.”

Commenting on the tooling performance after upskilling the engineers at Canterbury Tools, Josh adds: “We wanted to see exactly what we could get out of the Guhring tools. We were increasing our cutting depths and stepovers by 1 to 1.5 times as well as increasing our speeds and feeds while maintaining a much higher tool life than what we were previously getting.”

Discussing the switch to Guhring, Josh adds: “By switching to Guhring, we found a much higher material removal rate and this meant that jobs were on machines for less time. In the world of CNC machining, this is a massive. You always want the job to be ‘on and off’ the machine as quickly as possible. Additionally, not having to change the cutters as often has reduced the downtime incurred by tool changeovers. To remove, reset and replace tools is a process that can take anything from 5 to 15 minutes – the number of these tool changeovers has been drastically reduced. If you have a tool that you expect to change every hour, and then you change to a Guhring tool that gives you four hours of tool life, you have cut out three tool changes in just one job cycle. Additionally, you have slashed your tooling costs.”

Discussing the service provided by Guhring, Josh says: “Another main advantage with Guhring is their next-day delivery. The service is excellent and if we are really stuck, they can often help us with ‘same day’ delivery. Sometimes, we will have a customer with a breakdown. If it is an automotive press tool breakdown, it can be a very costly experience, so they will want items repaired or replaced immediately. We will pull late shifts, night shifts and work weekends to get everything done – but sometimes you may not necessarily have the tooling in stock to complete the job. So, being able to offer customers this rapid turnaround service and adhere to very short lead times is critical to our business – and it’s something we can only offer if we have the cutting tools and support available from Guhring for the job.”

Reaching for the stars

Superstar Components was started in 2006 with the single aim of cutting out the middleman and selling high-quality bike parts directly to customers at sensible prices. More than 15 years later, the company has grown from selling brake pads in a bedroom to a biker-run company with 3 warehouses, a large team and a wide range of products for both mountain and road bikes, building everything from gear rings and pedals to chain devices, brakes, bottle cages, seat posts, stems and more. Most of these parts are CNC machined in-house. 

The company now adopts hyperMILL CAM software alongside two Matsuura MAM72 machines, a Brother Speedio and a FANUC Robodrill as just a part of the plant list. The company recently adopted workholding technology from Hainbuch. Discussing the reasoning behind this, Neil Wilkinson from Superstar Component says: “I have been making hubs for mountain bikes for years, but one day one of our customers came to us and they wanted a very complex monobloc hub produced for a wheelchair wheel. It has carbon fibre leaf springs that are epoxy-bonded and this gives it a rough surface on the inside. Looking at the part, you would think it is a turned part, but it really is a round billet that is milled. So, we invested in a Brother Speedio MX140X1 from Whitehouse Machine Tools for a milled solution. The machine is more focused as a mill than a turning centre, but it can do all the things a turning centre can.”

Alluding to the Hainbuch solution, Neil says: “We fitted the machine with a Hainbuch mandrel – previously we were using a three-jaw chuck. This setup wasn’t very rigid, it was occasionally firing the part out and the surface finish wasn’t great. The hydraulically actuated drawbar inside the machine accommodates fully automated loading and unloading of the parts, so we can install a robot in the future if we desire.”

Highlighting the benefits of installing the Hainbuch MANDO T212 on the Brother machine, Neil adds: “The benefits are that because the system is clamping internally with the mandrel and it pulls down as well, it is always accurate on length, it’s always flat, it’s always concentric and it’s so rigid you get much better surface finishes. The surface finishes are unbelievably better than with the three-jaw chuck.”

Looking at the part, Neil says: “Our customer was previously making 14 different parts and there were a lot of warranty problems and component failures. Actually, there was so much handling that the process also cost a lot of money – as each part had to be loaded and unloaded repeatedly. This created a lot of risk and assembly time, as the parts had to be anodised. This all adds up to a very expensive bill of materials. You would think that a complex monobloc design is an expensive way of producing the part, but it was a massive down-cost for the customer and it meant that all of the tolerances are held in one place, there is no assembly and there are fewer parts to anodise. This results in a cost that is a fraction of what it was, and all the tolerances are much better. From my point of view, I could also reduce the cost as the part has a long cycle time with a lot of operator ‘walk away’ time. You can literally load the parts, start the machine and it just runs. The beauty of the machine is that it has an automatic door and a hydraulic drawbar that allows you to just take the part out and pop it back in without any need for a spanner. When you press go, the door shuts, the mandrel clamps and pulls down on the part – and it runs. I’m already loading the next machine by the time this machine has started running, so my tac time is literally 10 seconds.”

Zeroing in on setup savings 

Blending a passion for cycling with a career in manufacturing, Edward Mason founded Dward Design as a company that manufactures a range of titanium bicycle parts as well as undertaking general subcontract manufacturing. To speed up throughput, the Somerset company has invested in workholding technology from Lang UK. 

Located in Bath, Edward Mason used his engineering experience to start a small and successful machine shop manufacturing components for bicycles. Alluding to how the two blend together, Edward says: “Cycling and engineering go hand in hand together, and most of the cyclists I have ever met have some form of engineering experience. At Dward Design, we predominantly make drivetrain components such as chainrings, jockey wheels and parts that hold components that other manufacturers will make – like seat post clamps, top clamps for headsets and a range of other parts.”

Looking at the improvements that the company has made as it has progressed, Edward adds: “We made all sorts of improvements to our business. This ranges from having the facility to buy larger machines to having a 4th axis on a machine. The ability to change setups really quickly has also been instrumental. The ability to go from one set-up to another without having to change work coordinates and re-probe and re-align setups has been a major benefit, and Lang UK has been extremely supportive in helping us with that kind of work.”

Referring to the Lang UK solutions adopted at Dward Design, Edward says: “We are predominantly using the Lang zero-point system, so I have two 96mm plates and I also use a 52mm spacing on my 4th axis. This means I do not have to realign the 4th axis at all, and if I take the 4th axis completely out of the machine and then put it back in – I know my offsets will still be exactly the same.”

Looking at what the small business owner does with the 4th axis unit when removed from the machine, Edward adds: “I can release the Lang pins quickly and then the 4th axis is free. As I don’t have an overhead crane to lift the heavy unit out of the machine, I have designed and made a laser-cut hoist that picks the Lang and 4th axis system up and then slides it to the top of the machining centre where it locates into studs on the top of the machine.”

Referring to the benefits of having the Lang quick point plates and zero-point clamping system, Edward adds: “It’s a night and day difference. I have gone from 30 to 60 minutes of setup times to literally being able to change part setups in 10 minutes. When you have a lot of changeovers this is a considerable saving. Not only have I been able to reduce setup times between jobs, but I have also been able to reduce the number of setups per job. This is because I have more than one orientation that I need to hit, and with the 4th axis and the tombstone, I can make a lot of parts with fewer operations for each part.”

Discussing the payback of Lang’s workholding systems, Edward concludes: “For me personally, I don’t think I would be able to make the business that I run, work properly without the investment in the Lang systems. The investment has been easily worth it as it has drastically reduced set-ups and changeovers, saving significant time for my business.”

🎧 Making money in your sleep

Recently rising to the eighth largest manufacturing economy in the world, the route to continued ascension for UK manufacturing isn’t purely down to the well-publicised need for a national manufacturing strategy or government investment – a large burden of responsibility has to lie firmly at the feet of manufacturers and their reticence to automate. The International Federation of Robotics (IFR) frequently shines a light on how far the UK is behind other developed nations. The most recent report shows that 71,000 robots were installed in Europe in 2022, the UK accounted for just over 2000 of those installations. As a world leader in automation, MTD Magazine spoke with Leigh Tricklebank, the Sales Director for Western Europe at FASTEMS to find out why automation is still a cultural challenge for UK manufacturers. 

Ironically, our conversation with Leigh took place in Opmeer at RODIN Machining, a Dutch subcontract manufacturing business that has invested in a FASTEMS solution to manufacture anything from prototypes to low and medium production runs – with a high part and complexity mix. Not only were the MTD team astounded and excited by what we witnessed at RODIN, but we were also a little melancholy as to why we rarely see such levels of automation in the UK subcontract supply chain. 

Having a conversation with Leigh, he tells MTD magazine: “In the UK, there are upward of 5000 subcontract manufacturers using prismatic four and five-axis machine tools and there is an interesting demographic within that. There are small lifestyle businesses through to serious manufacturers making significant investments. All of these businesses have a similar problem, they need to get orders, they need to process the orders, manage the resources and deliver and serve on time. The level of process quality will differ between businesses, but the overall audience of 5000 companies is huge. Some of these businesses will have a perception that FASTEMS is a pallet automation system that can be expensive and is typically the reserve for OEM manufacturers. It’s painful to hear this in the UK, as these companies really need to look closer at what we do.”

“For example, we have been delivering Auto Load Devices for more than 20 years – only now we are seeing the gradual uptake of this technology in the industry. For the obvious benefits of increasing uptime, safety and consistency while reducing manual intervention. Auto Load Devices are now becoming increasingly important as we cannot find a generation of people that are willing to pick a part up, put it in the machine and hit the green button. It’s not only a monotonous job, but it’s a job that people don’t want. So, as years have gone by this has become more pertinent.”

“Reshoring work from overseas is a very real opportunity, but volumes are still typically low and complexity has increased tenfold with the need for diversity and JIT manufacturing. Complex parts, processes and problems are all there – but the volumes are low. It’s difficult for UK manufacturers to hear, but we are not even close to the G20 figures for robots per 10,000 people. Our position is something like the 22nd largest adopter of robotics in Europe – not the world. It is embarrassing. Ultimately, we have to share the word that automation is no longer a future vision – it’s a reality, and companies like RODIN Machining are embracing that reality. The ‘no-go’s’ for companies like RODIN was that they did not want manual data entry and manual actions – they wanted autonomy and automation. Subcontractors in the UK should be looking at these points and realising that they should be striving for the same goals.”

“There is a myth that FASTEMS is a system only for large companies and OEMs – it really isn’t true. We have shown that at RODIN Machining. It’s a start-up company with four guys. If you look at the areas where businesses generally have problems such as labour and skill shortages, we are taking all of these decisions off the shop floor. Businesses generally have problems on the application side of things on the shop floor, less so on the processing side of things like CAD/CAM. It’s the button pressers on the shop floor that can kill productivity. The challenge for these 5000+ subcontract manufacturers is that they take an order in good faith and calculate the recipe for manufacturing. After winning the order, subcontractors have to transpose that learning from the sales phase into the engineering department – determining what fixtures, tools and machines to use. This is where the challenges arise – challenges that FASTEMS can streamline and simplify.”

Building Strong Strategic Pillars

Looking more directly at the UK subcontract industry and overcoming the challenges, Leigh continues: “Subcontract manufacturers in the UK have several issues. These will range from not having scalability, struggling to increase profitability, and the inevitable chaos created by people – and FASTEMS can fix all of these things. To put it in simplistic terms, we have four pillars of People, Processes, Investment, and Profitability. Some companies can have a fantastic business, but it may be labour-intensive, regardless of having CAD/CAM, an ERP system, tooling and material databases, high-end machine tools and even an FMS. But what these businesses won’t have is an overriding process that autonomously takes billets from order to invoice and finished part. In the mix of 5,000 subcontract manufacturers adopting 4 and 5-axis machining, there are a lot of lifestyle businesses where owners do not want to be working over weekends or unsociable hours – they want to make money while they sleep. FASTEMS can provide that lifestyle business for UK manufacturers.”

Joining the conversation, Mikko Tuomaala, the Marketing Director for FASTEMS comments upon the pillar of ‘People’, Mikko adds: “What automation removes from the human is the ‘triple D’ of manufacturing processes – Dirty, Dull and Dangerous.  Nobody wants to do these jobs, particularly the younger generation. Additionally, if you think of a machine shop and the people that work there, if you don’t control the process and its intelligence, this will fall upon the staff and it will create a deviation in results. You want your highly skilled staff to intervene in the optimisation of processes and be more engaged in the business, leaving the mundane operations to the automation system. The understanding of the machining process doesn’t go away, it is just facilitated by the system and optimised by skilled engineers.”

Alluding to the pillar of ‘Processes’, Mikko says: “In UK manufacturing, there are particular islands of manufacturing, so at the beginning, there could be an ERP system or a CRM system – there is a wealth of data and machines that are often sat there doing nothing. To achieve faster throughput and improve costs, deliveries and quality – the process has to be fixed. What FASTEMS does with its MMS is it acts as the nucleus of the ecosystem bringing in the ERP, the MRP, encapsulating the machine tools, the materials and fixtures – it brings together the recipe to bake a great cake. FASTEMS gives customers the facility to control everything from the door where the material arrives to the finished part at the end, and we can visualise it with our situational awareness. We cannot fix bottlenecks, but we can give customers insights into why a bottleneck exists. We can identify what parameters are causing the chaos in a customer’s system – from this data, great engineers can fix the problems. Our software empowers engineers to identify problems and create solutions. Automation pushes manufacturers to realise what is obvious. The problem is often the process and not the machine tool.”

Discussing ‘Investment’ on a UK-wide basis, Leigh adds: “In the UK, we use terms like ‘manufacturing is culturally important’, but there has been little investment over the last 30 years. How do manufacturers get investment? They either go through the long-winded painful process of obtaining a grant and if that doesn’t work they get screwed by the bank on loans with personal guarantees against directors. The level of investment in the UK is embarrassing. We have more than 500 installs in Europe from around 200 customers and this is because our customers keep re-investing with us. We have RE Thompson at the RODIN event and they ordered a cell in 2007, a second system in 2008, and another in 2012. We have just won an order for a fourth cell that will keep their business running for the next 20 years. Our biggest customer in the UK is BAE Systems, the F16 should have been decommissioned around 10 years ago, but they have to keep the program running for the next 20 years on machines that are virtually obsolete – our FMS is managing that.” 

Looking at the pillar of profitability, Leigh continues: “Companies like RODIN Machining look at profitability completely differently from manufacturers in the UK. UK manufacturers often value automation as a third of the cost of a machine tool. For example, a company may buy a machine tool for £500,000 and they will accept that it will run for 12 to 16 hours a day. Then they realise they need lights out machining for the remaining 8 hours – and this is where the valuation of one third comes from. So, they will be prepared to spend £150,000 on the automation of the machine tool. If a manufacturer buys two machines, they have an automation budget of £300,000 – we can automate two spindles for this, but it’s a poor equation. At RODIN, they started the company with four machine tools and spent 1.5 times that on automation – and look at what they’ve achieved. They don’t care about the capacity of the CAM system, the machines and the people – they care about the capacity of the process. They want to create a drumbeat of creating constant cash flow, autonomously with automation, 24/7 and 365. It’s a completely different way of looking at the same problem. When UK manufacturers look at the problem from a different perspective, they’ll find the resolution to the issues of People, Processes, Investment, and Profitability through FASTEMS.”

Targeting the ‘Pinch Points’

Looking at the pinch points for UK manufacturers, Leigh continues: “We are intrinsically linked to new machine tools – and we shouldn’t be. Ideally, I would like FASTEMS to be linked with manufacturers and their existing machine tools. If we are linked with the purchase of new machine tools, we are there like Oliver asking for scraps from the begging bowl. We want to have conversations with manufacturers regarding their business problems, not the component problems. Most manufacturers will have business issues such as being too expensive, not being able to produce parts quickly enough, stock rates and production downtime being too high, unskilled staff and a struggle to meet customer demand. These are the issues that I hear regularly.”

“We are not here to sell machines and robots, we are here to solve business problems. At FASTEMS, we look at how we can set your business up for the next 40 years – we cannot do that by looking at the X, Y, Z and the A, B and C. The punchline is that at FASTEMS, we don’t sell a product – we sell change. When businesses have a goal and a vision, that is where we can help. The attitude across Europe is that ‘if we make this investment, we trust that we will achieve things’. In the UK, the attitude is very much that if we have an order, we have to get it completed by next week – how do we do it and how can we make the part faster? The next step is to run around the machine tool companies and pick a vendor. However, this is often done with no process, no people and no best practice – it’s just compounding the existing problem.”

“Almost all subcontract manufacturers have chaos, we want to have the adult conversations that look beyond the existing project and what manufacturers want to do over the next 5 to 10 years. OEMs do not have this level of chaos, they have strategic thinking that opens the lines of communication with FASTEMS.”

Adding to this, Mikko says: “It is like playing a sport, as you progress through different levels, you see the game differently. Manufacturers need to stop being in reactive mode, sit down and think more strategically about the things that will solve their challenges.”

🎧 Starrag HD reduces cycle times by 30%

Now available from Starrag Heckert, the STC1250 HD is the latest addition to the renowned STC Series that has been designed to provide unrivalled economy in the machining of the most demanding aerospace structural parts, multi-blades and casings. For those challenging components with long cycle times, the STC Series provides a whole host of practical options. The latest arrival, the STC1250 HD machining centre provides excellent static and dynamic properties as well as a tried and tested rotatable head, making it the new benchmark for heavy-duty titanium and Inconel machining.

Commenting on the latest addition to the portfolio, Lee Scott from Starrag says: “This is a 5-axis machine with a B-axis table that holds the component and an A-axis on the head, you can actually have an A and C-axis head as well. This new HD is predominantly for optimised roughing and high surface generation finishing of exotic materials.”

Discussing the differences between the new STC1250 HD and its predecessors, Lee adds: “What hasn’t changed from previous models is the head configuration. The head is very stiff and rigid and it has a compact design with a range of spindles, particularly geared spindles. We have an impressive drive system in the spindle, which is a gear-driven HSK100 unit and we also have a dampening brake, so we can lock the spindle and stop it from swivelling when undertaking very heavy rough machining. This also helps with dampening when machining in 5-axis mode. This provides very efficient heavy-duty machining capability that is perfect for aerospace structural components.”

Looking specifically at titanium machining, Lee continues: “In the UK alone, we have around 30 STC installations, it is a very successful range. What we have seen from customers is a desire to prove the roughing capability of the machine with no compromise on quality and accuracy. That is exactly what we have achieved with the STC1250 HD. This has been achieved by changing the linear rails to a hydrostatic system – do not get that confused with a box-way system. We have an advanced hydrostatic system, which is a box guideway with a continuous oil film between the two metallic parts that never drains away, so you have zero-friction with no ‘stick-slip’.”

The STC1250 HD offers a 1.25m by 1.25m pallet with a large work envelope for accommodating workpiece loads up to 5,000kg on the pallet. This is complemented by an X, Y and Z-axis travel of 2.2 by 1.5 by 2.1m with a swing diameter of 2.2m. With such a large work envelope, the new features in the STC1250 HD can offer astounding benefits for manufacturers with large parts that may have considerable cycle times.  

Discussing reports that the new features of the STC1250 HD can reduce cycle times in titanium by more than 30%, Lee adds: “At Starrag’s Aerospace and Turbine Competence Centre in Rorschach, we saw a 63mm deep cut with a porcupine cutter where buckets of swarf continually fall into the base of the machine. Traditionally, what would have been three or four passes with a tool can now be done with a single pass. The machine may draw more power in that single pass, but overall it has a significantly reduced cycle time when compared to the previous method of multiple passes.”

Highlighting how the hydrostatic system works, Lee adds: “There is a lot of oil in the system, but it is all contained in a recyclable system. On large guideways, there is a thin film of oil of 15 to 20µm. When a large structure moves around, it could theoretically displace the oil. To eliminate this, we have an innovative multi-pocket system that controls the functionality, pressure and volume of the oil to guarantee the accuracy of the entire machining system. Each axis is split into several pockets and by controlling each of the pockets, we can control the entire system within the machine. This is what ultimately enables this machine to take heavier cuts with better surface finishes whilst reducing the overall cycle time of components. Only launched in June 2023, after enjoying immediate sales for this product, Starrag has a lot of significant projects in the pipeline for the STC1250 HD and these will take some months to go through the process, but there is little doubt that the industry is already seeing the potential merits of the STC1250 HD.”

Getting a gripple on laser 

The purchase of a Nukon 2D fibre laser machine from Nukon Laser UK has brought vertical integration, product development and sustainable manufacturing benefits to Gripple, a manufacturer of wire joining, tensioning and suspension systems. The installation of a Nukon 2D flat sheet metal fibre laser machine at its recently opened Norfolk Bridge manufacturing site in Sheffield has reaped considerable benefits for Gripple.

With increasing global sales for its Fast Trak® bracket systems for mechanical and electrical service suspension, a desire to equip its Ideas & Innovation team with greater opportunities for new product development, and a drive to reduce its carbon footprint through greater vertical integration, Gripple took delivery of a new Nukon 2D fibre laser machine in 2022. 

Supplied by Nukon Laser UK, the sister company of Unison Ltd, the Nukon Eco 315 4kW fibre laser offers power and performance. It is equipped with solid-state American-made nLIGHT fibre lasers as standard. After considering several fibre laser machine manufacturers, Gripple shortlisted Nukon and another leading brand. With product quality and capability provided by Nukon machines, it was the commitment of Nukon Laser UK’s Sales Director, Steve Haddrell, to fully understand Gripple’s laser-cutting requirements, that secured the sale.

At Gripple’s Norfolk Bridge site, production surrounds the manufacture of the company’s Fast Trak® bracket systems, as well as solutions for the rail industry and utility solar applications. For this type of work, Gripple typically uses CNC-controlled punch machines. However, with an ‘Ideas & Innovation’ team continually looking to provide new solutions to the challenges faced by customers, and a company-wide drive to bring even more production in-house through a vertically integrated supply chain, it wasn’t long before the new Nukon fibre laser began making its mark.

“Following installation, our Nukon fibre laser machine quickly gained a key role in the cost-effective manufacture of our OSHPD OPA-2123-10 seismic bracing and blast protection systems – brackets developed for some of the most demanding environments in the world,” comments Claire Tunnard, production manager at Gripple’s 21,000sq/ft site. 

“The machine is also being used to produce components for our lightweight, easily transported solar cable hangers. The ease of programming, speed, accuracy and flexibility are also providing our Ideas & Innovation team with exciting opportunities for new product development. The Nukon fibre laser is being used to produce components for the manufacture of machine tools that will be based at other Gripple sites.”

Significant savings from cutting with air

From the outset, Gripple’s manufacturing team was impressed with the Nukon laser’s build quality, performance and precise cut. “Nukon Laser UK has shared a wealth of advice and technical knowledge with us, including specific production processes and the most cost-effective gas to use depending on the material being cut. For example, our solar cable hangers are cut exclusively using compressed air – an essentially free medium,” says Claire Tunnard. By cutting with compressed air, rather than costly nitrogen, which looks set to remain at historically high prices, Gripple is also benefiting from significant savings that help it remain competitive. 

Nukon Laser UK’s Steve Haddrell adds: “For us, it is all about supporting the customer, whether it’s advising on the best fibre laser machine, achieving a particular finish, or using a particular gas – and all with the highest levels of aftersales service as standard. We work closely with Gripple and will continue to do so.”

The Nukon Eco 315 4kW 2D fibre laser machine purchased by Gripple was specially developed for organisations wishing to add value to in-house manufactured products and for subcontractors either starting in 2D laser cutting or with demanding flat sheet metal cutting requirements. Nukon Eco machines offer high-spec features including advanced Lantek Expert CAD/CAM nesting software and American-made nLIGHT fibre lasers, with CutLine Adaptive Beam Shaping.

🎧 5-axis makes low-cost jobs financially viable

Many prismatic machining contracts are ideally fulfilled on a 5-axis machining centre that enables components to be produced cost effectively. This is because the two rotary axes are able to position the component quickly and automatically in various orientations for milling and drilling without expensive fixtures and multiple set-ups. A problem arises when the components do not command a high selling price, as most 5-axis machines are a considerable investment.

Subcontractor G&J (CNC) Services in Paddock Wood has apparently found a solution – the Leadwell V-30iT 3+2-axis BT40 machining centre from WH-Lead, Towcester. The entry-level price of less than six figures belies the 5-axis machine’s extensive capabilities. The hourly rate that the subcontractor charges based on the investment allows less complex prismatic components to be produced efficiently at prices that compare favourably with those quoted by competitors in low-wage countries.

The V-30iT has a novel configuration that consists of a 205mm diameter rotary table mounted on a swivelling trunnion driven from one side. It is supported on the other side by a similar unit built into the side of a 450 by 300mm fixed table. It is unusual on a machine that is already inexpensive to find such a major addition. The fixed table can be used to complete a 3-axis operation on a part weighing up to 50kg before it is transferred to the rotary table. By that time, the part must weigh no more than 35kg if it is to undergo machining at up to 45 degrees tilt, or 25kg if the trunnion position is steeper.

The owner of G&J (CNC) Services, Charlie Naismith, is in a good position to comment on the merits of the Taiwanese-built machine compared with more expensive, fully interpolating 5-axis machining centres of German and Japanese origin used at his other four engineering sites in the south-east. The group of companies, CTN Group, boasts around 100 CNC machine tools of which 10 are 5-axis models.

Mr Naismith said: “Depending on the value of the parts being machined, which is normally down to their complexity and the material used, you have to make sure the figures add up. Much of our throughput is fairly simple 3+2-axis work in mild steel and aluminium that customers will not pay a premium for, so the Leadwell machine is perfect.”

“We use it in 3-axis mode for much of the time, but the 5-axis functionality is there for when we need it, saving costs associated with workholding, handling and work-in-progress. At the same time, it helps with accuracy by being able to access parts with shorter tools and by cutting down on manual refixturing.”

He also appreciates the ergonomics of the V-30iT, pointing out that the rotary table when flat is at the same level as the fixed table, so there are no clearance issues. The machine is also well specified, with 800mm of X-axis travel, 460 and 387mm travels in Y and Z, roller bearing guideways, a 12,000rpm spindle, a 24-position tool magazine with 1.8 seconds cutter exchange and 48m/min rapids in X and Y, 36m/min in Z. 

Control is provided by a Fanuc 0i-MF Plus CNC system, although Siemens, Fagor and Heidenhain are optional, as are specification of 4+1 or full 5-axis interpolation. Another benefit of 3+2 CNC apart from the lower cost, according to Mr Naismith, is that engineers in the Paddock Wood factory can step up to 5-axis machining and build a portfolio of new work around the enhanced capability, while taking advantage of the extra 3-axis capacity for regular work.

The first Leadwell machine, which was also G&J (CNC) Services’ first 5-axis machine, was installed in 2021. Its purchase was prompted by the need to produce a particular agricultural industry component that would not have been feasible to put onto a 3-axis machine. 

A second, identical machining centre followed a year later to provide extra capacity and equipment redundancy. Both machines were available ex-stock from WH-Lead’s Towcester showroom and delivered within a fortnight, together with Renishaw tool and workpiece probing, Filtermist extraction and a post processor for the OneCNC CAD/CAM system. WH-Lead’s customary high level of ongoing after-sales service and support is being provided.

Generally speaking, parts that previously required four or five separate operations are now produced in two, sometimes without leaving the V-30iT if pre-machining is done on one of the tables. A typical component cited by Mr Naismith for a fluid transfer equipment manufacturer is produced in this way, resulting in a 30% shorter floor-to-floor time compared with when it was produced in four operations on different 3-axis machines. 

A further advantage of the new process route is that operator walk-away intervals are longer, allowing more meaningful work to be performed elsewhere in the factory while machining is in progress. As a result, it is likely that more and more jobs at G&J (CNC) Services will be transferred to the 5-axis plant as time progresses.

🎧 Offshore subcontractor takes off with Vulcan

Located in Moray, North-East Scotland, an area famous for its Scotch Whisky, Standfast Precision Engineering Ltd provides subcontract manufacturing services that are far more edifying than a tipple. The manufacturer continually invests in machine tools to serve its clients in the offshore and whisky distillery sectors. The latest investment is a Vulcan 710L VMC from the Engineering Technology Group (ETG). 

Located in Craigellachie where the River Spey meets the River Fiddich, Standfast has continually invested in new technology to enable the production of high quality components. Primarily working with the oil and gas industry, Standfast has witnessed significant growth in recent years as the offshore industry has enjoyed a renaissance. With a facility that incorporates everything from manual and CNC turning, milling and EDM machining, the company is evolving its business assets to satisfy the demands of its clients. 

The latest acquisition, a Vulcan 710L VMC with a 4th axis Lehmann rotary unit from ETG was purchased to provide additional capacity and increase the throughput of its smaller components. As Company Owner and Director Graham Wilson says: “We had a small bed 3-axis machine with a rotary unit, but the compact work area was limited even further by the 4th axis unit. This meant we could only process very small parts or we’d have to transfer components to our larger bed machines that are dedicated to larger jobs – disrupting our workflow and creating capacity issues. We spoke to Ross Milne at ETG’s Scottish distribution partner RAM Engineering & Tooling and he recommended the Vulcan 710L VMC.”

“We reviewed the market, looking for a machine with a Siemens CNC in a short lead time, as our workload was ramping up and the issue was causing a bottleneck. ETG provided the solution with the Vulcan, and it has been a tremendous asset since it was installed,” adds Graham. 

With a limited floor area, the compact Vulcan slotted straight into the shop floor. The outgoing machine only had a worktable of 500mm, which was too small to fit both a 4th axis unit and a vice for 3-axis work. However, the spacious work area of the Vulcan provides a worktable of 760 by 420mm. Commenting upon this, CNC Machinist at Standfast, Mr Scott Coull says: “With the space in the Vulcan, we can fit the 4th axis unit and a tailstock to stabilise larger parts.”

Operating the machine daily, Scott adds: “We program parts at the machine and the new Siemens CNC has a large touchscreen interface that improves programming speed by at least 30%. We typically produce batches from 10 to 20 off, so we can program 10 to 20 jobs each week with each program taking from 15 minutes to a couple of hours, so this saving in programming time is significant.”

Looking at the build quality and performance of the machine, Scott adds: “The Vulcan is a more rigid and robust machine than its predecessor and this enables us to undertake heavier cutting conditions. Furthermore, the previous spindle had a maximum speed of 8000rpm and the Vulcan provides 10,000rpm, this significantly improves our productivity.”

The family business owned and run by Graham and his wife Michelle has also witnessed improved surface finishes, product quality and reduced downtime since the acquisition of the Vulcan. Scott adds: “Whilst the Vulcan has a tool setting probe that eradicates our previous method of using a dial gauge on every new tool that we put in the machine. This can save us a couple of hours of manual tool setting on the machine each week. In addition, the rapid tool changer is at least 50% faster than the previous machine.”

Concluding on the acquisition, Graham says: “We needed a machine with a particular specification for our requirements that was going to deliver reliability and performance. The Vulcan machine from ETG has more capacity, more torque, and a streamlined 4th-axis system and it provides the space for us to machine relatively large parts in either a 3-axis or 4th-axis setup.”

GROB delivers automotive solution

With a forward-looking concept consisting of a GROB G350 Access, a flexible GROB GRC-R20 robot cell with integrated GRESSEL R-C2 clamping system and control software from PROCAM, thyssenkrupp Automotive Body Solutions can undertake flexible automated production. 

Located near the Luxembourg border, thyssenkrupp Automotive Body Solutions has been supplying the auto industry with its standardised and flexible solutions as an integrated body builder for decades. The company, first worked with GROB in 2008. 

At the end of 2008, thyssenkrupp Automotive Body Solutions invested in its first automation system with an integrated 5-axis machining centre. The robotic system was equipped with combined pallet and workpiece handling, as well as the possibility to integrate a second machine. Ten years later, this was expanded with a second 5-axis machine. “Here GROB was the only company willing to help us. Especially since there were already problems with the automation at that time,” remembers Production Manager of thyssenkrupp Automotive Body Solutions, Thomas Hahn. 

The solution was found with a GROB G550. After extensive tests, with additional integration of a new control system from PROCAM, it was integrated into the existing plant. The challenge for GROB’s tender designers was even more intensive and extensive for the second, extremely demanding task from thyssenkrupp. For its small parts series production, the company planned another 5-axis machine and automation for a wide variety of workpieces that can be flexibly produced in two setups. Despite the difficult conditions caused by Covid, GROB managed to successfully cooperate and closely coordinate with regard to an optimal solution. As with the first automation system, PROCAM’s control software technology was used for this system as well. For this order, too, the primary objective was to find an overall concept based on the customer’s requirements. “In this application, we not only had to meet the requirement of a flexible partial spectrum, but also as a general contractor we had to find a clever system of how to coordinate our G350 Access, the GRESSEL R-C2 clamping system and the control software from PROCAM with the customer’s requirements,” GROB  Technical Proposal Ralph Birkle explains. 

The GRESSEL robot gripper was used for six-sided machining of the part, as it can be used simultaneously as a gripper and a clamping system. This means that there is no need for pallets or many grippers. In sum, this system is not only highly flexible, but can also handle many different workpieces with just a few grippers. 

“At this point we favored the use of a pallet changer, so that loading and unloading of the GRESSEL clamping equipment is possible, and machine waiting times can be reduced to a minimum,” explains GROB area sales manager Jürgen Rieger. Another advantage is that directly after the first operation, the robot takes the clamp out of the pallet and moves to a reclamping station where another gripper is already located. This unhooks the gripper at the top, moves down and transfers the part, rotated by 180 degrees to the changeover gripper.“  

Developing an overall concept for such an automation system is one thing. Getting it up and running can only be done as a team, with an intensive exchange at eye level among each other and with a lot of know-how and experience. This successfully producing automation system is the result of intensive cooperation between GROB, GRESSEL, PROCAM and thyssenkrupp Automotive Body Solutions. 

Thomas Hahn, the Production Manager at thyssenkrupp says: “It was fascinating that the GROB calculations for the specified workpieces and their cycle times were correct so quickly. A clever solution, as we were able to become much more efficient than expected thanks to the pallet changer and the robot gripper as a vice.” 

Adding to this, Ruben Erbel, Application Engineer at thyssenkrupp adds: “I have been working on this machine since last year, from the setup to first acceptance. I am very satisfied with the G350 Access. We started with five to eleven parts in a small series. Now we are already at 20 to 25 components, which proves that everything works well.“

Dugard putts the hours in with golf club manufacturer

If you put an engineer with a love of golf together, you get Sink Golf – a company located in West Sussex that manufactures golf putters. This South Coast manufacturer has recently invested in a Dugard 760 machining centre from Dugard Machine Tools to machine its bespoke golf clubs. 

Discussing how the Littlehampton business started, Company Founder Olly Longlands says: “Four years ago I was living out in New Zealand and got into CNC manufacturing. I loved it so much that when I returned home to the UK, I bought a 2008 Dugard machine at auction – and I didn’t even know how to turn it on. I called Dugard and they were absolutely unbelievable, with their help and learning from YouTube videos, I managed to get my business up and running.”

Upon his return to the UK, the entrepreneur worked in the family sheet metal business whilst spending his evenings and weekends getting his business off the ground. Now, the small business receives enquiries from online channels like Instagram, Facebook and even LinkedIn. From the enquiry phase, Olly liaises with customers on their bespoke requirements and then designs the putters using FUSION 360. When a final design is confirmed, Sink Golf will programme the putter in FUSION 360 and send the programme to the Dugard machines on the shop floor. 

Discussing the arrival of the latest Dugard 760 machining centre, Olly adds: “I decided in January to run the business full-time and it has just gone from strength to strength. I got so busy that I couldn’t keep up with orders with just the one machine, so I went out and bought a new machine – and it wasn’t going to be anybody else other than Dugard.”

“We are machining two types of material, 303 stainless steel and mild steel. Now I have two machines, I can do the first operation on the new machine and then do the facing on the older machine. I enquired about the machine and from there it all happened so fast. Mark from Dugard was brilliant, and he told me that Dugard had a machine coming in. From order to delivery and installation, the process was so fast and easy, it was just brilliant,” says Olly. 

The benefits of the new Dugard 760 3-axis machine installation are evident. As each club is bespoke to the individual golf enthusiast, production times differ from club to club. “Some clubs will have four hours of machining time and another we just produced was a Damascus club (a process where multiple metals are joined in layers under extreme heat) that took more than 32 hours. So, the processing time varies. However, the rigidity of the new machine enables us to run our tools faster and harder whilst improving our surface finishes and tool life. This makes us 40% more productive and secondary hand finishing times are reduced.”

The new Dugard 760 has a 20-tool ATC and when combined with the 16 tools in the older machine, this reduces set-ups, tool changeovers and downtime. As an example, the rough machining time on the previous machine would be 1 hour 15 minutes and the new Dugard 760 has reduced this to less than 40 minutes, a 40% saving. Furthermore, tool changeovers on the ageing machine are 11.2 seconds and the new machine can change tools in just 2.4 seconds. 

Commenting upon the benefits of the new machine compared to its predecessor, Olly concludes: “The new machine has a swarf conveyor that saves a lot of time and I can keep the machine running for longer throughout the day without downtime for cleaning and removing swarf. With regards to machine running hours, this can depend on how finely detailed the build of the golf club is. Sometimes the machine can run for up to 8 hours a day and other days it may be just 3 to 4 hours. I recently did a job to create an accessory for golfers to use on the green. To produce this, the machine was running constantly day and night for four days – the machine ran superbly with no problems. If I ever did have any problems, I know that Dugard be there to help as the service from them is brilliant.”

🎧 Prima Innovations are shear class

In the November issue of MTD magazine, we reported on our visit to the Prima Power factory in Seinäjoki in Western Finland. We toured the manufacturing facility and were absorbed by the efficiency of the plant. In this issue, we take a closer look at the ‘Tech Centre’ – the showpiece for the developments coming out of the Scandinavian facility of Prima Power. By Rhys Williams

In 2022, the MTDCNC crew were lucky enough to get an invite to the Prima Power headquarters in Turin. Like the architecture of northern Italy, that facility was incredibly impressive with multi-axis lasers, additive manufacturing and automation. It was truly like nothing we had seen before – that was until we landed in Prima Power’s Seinäjoki plant in Finland. 

In our November issue, we noted how the state-of-the-art 20,000m2 Seinäjoki factory was the daily commute for 250 staff while another 150 employees would primarily work remotely from other parts of Finland or serving customers around the globe. The largest department in the Seinäjoki company is production, employing 40% of the total staff (including the installation group and customer training). The second largest department is R&D, pushing the boundaries of product development. The tech centre is the epicentre of that innovation.

As the centrepiece of the state-of-the-art Seinäjoki facility, the 7000m2 centre demonstrates a complete armoury of solutions. During our visit, this included the Laser Genius+1530 with the PSR (Picking and Stacking Robot) and the new EBe 2720 servo-electric driven panel bender that demonstrates the company’s latest API technology. The EBe 2720 panel bender in the facility forms part of a complete PSBB (Punch, Shear, Buffer and Bend) automation solution in the Tech Centre. At one end, this colossus automation system that stretches some 40m, has the Combi Genius CG1530 laser and punching machine that is fed by the Night Train Genius automation system that has more than 60 storage cassettes – each able to hold 3 tons of sheet steel. 

Completely configurable to the demands of the end user, the impressive Night Train has the CG1530 at one end and at the other, a PSBB line including a Shear Brilliance 1530. Sheets fed to the Shear Brilliance 1530 are then transferred to a buffering station where sheets and parts can be removed, added or flipped over for transfer to the final station, the EBe 2720 panel bender. During our visit, the exceptional level of flexibility and automation was demonstrated with a complete kit of parts being manufactured for an office furniture assembly.

Taking a walk around the Tech Centre with Prima Power UK General Manager, Mr Barry Rooney, he showed us the new EBe2720 (Express Bender) servo electric panel bender. The standalone EBe2720 is one of several models that vary to support different sheet dimensions. Capable of loading automatically from the loading table with precut blanks or being connected to a PSBB (Punch, Shear, Buffer and Bend) for complete automation, the EBe2720 has evolved to deliver low running costs, low maintenance requirements and most importantly in today’s current climate, very low energy consumption. 

With the machine having a seamlessly endless number of options to maximise flexibility, the EBe2720 offers a complete array of tooling designs to accommodate complex profiles. Here, the additional tools and bending blades for small and/or special bends allow small parts to be bent and corrected from a sheet with particularly narrow channels. It is here that the Advanced Profile Inspection (API) technology, a relatively new advancement from Prima Power stands above the innovation of its rivals.

Describing the API technology, that is available on a number of the Prima bending machines, Barry Rooney says: “The API system is not completely new, but it is well proven. The API system has a light source and a camera, it uses the light source to see the shadow of the part very accurately. It determines from that what the measurement actually is and then corrects the part. It is like a visual recognition where the machine can identify a measurement and apply a correction. When the system applies the correction, it then watches for spring back and other deviations, so it may do two or three corrections before it gets the right angle. Once it has that angle, it knows what the cumulative correction factor is – and it uses a correction factor again for the next bend. So, it may take two or three strikes at the first bend and the intelligent system will then apply the correct K Factor (ratio between material thickness and the neutral fibre axis) to subsequent bends. When it comes to the second bend, the system intelligently knows the K Factor, but still measures the bend. The time it moves on to subsequent bends, the machine intelligently knows exactly what factors to apply. Once this is in place, an operator can set the machine to check every fifth or tenth part, for example, to ensure it is adhering to quality-control factors. Our system is unique, other solutions may use a process that checks the measurements, but these rival systems don’t learn from the material and processes. We have a patent on this technology, which can measure and correct the part in real-time.”

Alluding to the UK customer uptake for machines with these new features, Barry says: “We have a lot of customers that want the API technology for its automated quality assurance whereas the DNP is a game changer for companies producing small, narrow profiles such as frameworks and edgings alongside other, larger parts. Other features that have been added to the machine are typically generational updates such as the control system and process optimisation.”

Shear Brilliance

Upstream from the EBe2720, is a buffering in balancing station. Here, parts can be removed, added or flipped over before processing on the EBe2720. This balancing station is necessary for the technical centre, as upstream from the EBe2720 is the Shear Brilliance SB1530 – a punching and shearing machine that can churn through the work with a strike rate of 1300 holes per minute. 

Launched at the Euroblech exhibition last year, the Shear Brilliance machine in the tech centre has 30 turret stations, 30-tonne punching force and a staggering 210m/min axis speed. As Barry adds: “Both the Shear Brilliance and Shear Genius are machines that are so quick, they are typically embedded with our automation solutions. You have to have automation for the high number of parts that can be produced in such a short time – otherwise, customers would be continually loading and unloading material, so the machines are designed and optimised for an automated environment.”

“As our high-performance machine, the Shear Brilliance can punch 1300hpm at a 1mm pitch and has a 30 station turret. This exceeds the 16 and 20 stations on the Shear Genius machines. On 16-station turrets, a large index tool and/or multi-tool can be allocated to each position whereas on the 20-station turret, only every other position can accept an indexable multitool. However, on the 30-station turret on the Shear Brilliance, we do things differently. We have a larger number of stations and every other position will be up to size D indexable multitool and the smaller positions accommodate single tools, however, as with the 20 stations on the other machines, we can put multi-tools in the small positions.”

“We can hit the correct tool as the intelligent RAM will work with the multitool to select the correct punch inside it. The intelligent RAM and an indexing multi-tool will work together to optimise positioning and maximise productivity. A fixed non-indexable station can also accommodate a multitool – you may not be able to turn the tool, but you can turn the RAM and this will select whichever tool it needs. The overriding aim is to create optimal flexibility for all scenarios, thereby eliminating tool changeovers except for sharpening. On many of our competitor’s machines, they don’t have this flexibility so they need to frequently change tools. Some machines rely on tool changing, or tool changers to create the capacity – on our machines, the tooling is in the turret at all times and ready for use. This means we can sit with customers and work out what their production requirements will be and set up the turret around the customer.”

The Brilliance and the downstream EBe2720 are both fed by the Night Train automation system. Discussing this, Barry adds: “On the system in our Tech Centre, the Night Train works with our TULUS user interface software and the NC Express CAM software. TULUS is the user interface and office software that comes in many guises, so customers can select production and process monitoring, it can be interfaced to an ERP system via the TULUS office that offers different levels of connectivity. TULUS can work with an ERP system to do all the scheduling and the programming, so when it comes to production – everything has been done and the CAM software has prepared all of the parts and the nests.”

“The Night Train and connected machines interface into that system and it will then know what parts it will produce on specific dates and times. The system can even be set to schedules where it can run filler parts in between production runs to maximise utilisation and minimise scrap. You can literally automate the system to connect to the customers’ ERP and the CAM software and TULUS can take care of everything from scheduling and nesting to material management, process tracking and production reporting. Furthermore, the Night Train is a storage system – so it can drastically improve factory layout and inventory management. We have one customer that has bought the Shear Genius and he has opted for a tower system, as this will take all of his material off the floor and optimise his floorspace.”

Set parallel to, and working in conjunction with the Night Train was the Combi Genius 1530. Utilising the same technology as the punching machines in the Prima Power portfolio, the CG1530 incorporates indexable forming, tapping and marking to increase process possibilities. The fully servo-electric machine is equipped with a 3 or 4kW fibre laser head and this enables the CG1530 to utilise the laser to replace conventional slitting tools to increase material yield using common edge lines, or allow more complex geometries to be cut. “The Combi Genius is an extremely popular machine due to its flexibility and capability, which is emphasised in the configuration of the tooling turret. 

Standing alongside the Combi Genius 1530 in Seinäjoki was a 2D Laser Genius LG+1530. We reported on this high-performance 2D fibre laser machine during our visit to Prima Power Turin last year. However, the Laser Genius LG+1530 in Seinäjoki was connected to the latest Picking & Stacking Robot (PSR). As Barry continues: “The PSR isn’t anything new for our company, but the PSR connected to the Laser Genius+ has been newly developed for that machine. Essentially, the materials are sorted and passed through the tower and then out to a station where parts are picked and stacked from laser-cut sheet. What we are doing is taking the cut sheets away from the system. This works outside the laser, so the laser can continue cutting whilst the PSR sorts the components, takes the skeleton sheet back to the tower, and then gets ready for the next sheet. If there is any issue that prevents a part from being lifted from the skeleton, the intelligence of the system sees this as it detects the sheet being lifted with the part. If the part does not separate from the skeleton, the PSR will shake the skeleton to separate the part. After a preset number of attempts, if the part is not separated from the skeleton, the PSR will move on to the next part – but the machine will know that the part has not been cut correctly and it notifies the operator that the part is still in the skeleton.”

The Future

Looking to the future, Barry says: “The current trend in the global marketplace is a scarcity of manpower, skilled manpower is even more scarce. Furthermore, energy and raw material costs are increasing and the quality of the material supply isn’t necessarily what it used to be. We are incrementally removing the need for highly skilled staff to alleviate our customers of this very real concern. Our full range of integrated solutions optimise processes, automates production, enhance efficiency, and support growth through modular and scalable solutions. Our technology is continually being developed to be more environmentally efficient whilst delivering productivity and cost benefits – we have been at the forefront in delivering technology to support these market requirements for more than a generation, and as you can see, this pace of evolution is only accelerating.”

🎧 Collaborative R&D helps take the weight off civil aerospace

Engineers’ obsession with weight and strength is reaching new heights in the aerospace sector. A range of technologies are being developed for manufacture, many with research centre support, that are designed to cut weight and carbon in aviation. By Will Stirling

It was a good landing at the end of 2023. Commercial aircraft orders and deliveries are flying high, and up in 2022 by some eye-catching margins. It seems like aerospace production is back to pre-pandemic levels. According to aerospace group ADS, 2,430 total aircraft orders have been placed globally to 6th December, a 43% increase on the same period in 2022. Single aisle aircraft account for just over 80% of orders placed this year, demonstrating the rapid recovery in the domestic and short-haul travel industry post-pandemic.

Airbus had recorded 1,395 net orders (gross orders minus cancellations) by the 30th of November, beating its full year 2022 orders (1,041) by 350 aircraft with a month to go. Deliveries to date are 623, again set to beat FY 2022 deliveries of 663. Boeing booked 114 gross orders in November, taking orders to 1,207 by 13th of December. The US plane-maker has delivered 461 aircraft to date – orders and deliveries both up on 2022 numbers. Boeing’s official backlog goes from 5,239 last month to 5,324 as of November 30th and like Airbus, its single aisle aircraft – in particular the 737 family – are the most popular type. To show the comparison with Covid and pre-Covid demand, Airbus has not had such a strong order book since 2014 (1590 orders) while in 2020, it received just 373 orders, about one quarter of 2023. The two main primes are chasing a production rate of about 65 aircraft a quarter, in fact Airbus has stated it wants ‘rate 75’ by 2026.

In November the government announced an Advanced Manufacturing Plan with £4.5bn of funding for sectors including automotive and aerospace, for five years starting in 2025 – a bit sneaky to project the cash forward, given that a new government will have to honour this future spending pledge.  £975m is earmarked to support the development of energy-efficient and zero-carbon aircraft technology.

Primes and tier ones are straining to develop low carbon technologies in aviation such as lighter but equally strong parts, sustainable aviation fuel, hydrogen, lighter wing skins, 3D printed structural parts. These endeavours are backed by the Aerospace Technology Institute, a government agency that has granted funded £1.9bn to aerospace companies, near-match-funded by industry, which has a new drive to cut carbon in aerospace called Destination Zero – see below.

Here are some exciting low carbon programmes and components in 2023. 

First transatlantic SAF flight 

On 28th of November, the first flight by a large passenger aircraft powered only by sustainable aviation fuel (SAF) completed a flight from London Heathrow to New York’s JFK airport. Hailed a success, observers remarked the shortage of SAF supply is a barrier to adoption and more lightweighting and propulsion technology will be needed to hit emissions targets.

50% lighter landing gear

Think of the incredible forces that go into landing gear when aircraft land – the huge mass of the plane, hitting hard into the ground at speed. Now remove half the weight in the landing gear. That’s what TISICS Metal Composites of Farnborough have done – in one key component of the gear, to begin with. It uses metal composites, a blend of titanium or aluminium with a ceramic matrix, to remove up to 50% of the weight but retain the component’s full strength. This year, TISICS won an Aerospace Technology Institute (ATI) award for the product. 

Part of a project backed by £2.5m in R&D funding from UK Research and Innovation (UKRI) and Innovate UK, in collaboration with Safran Landing Systems, with its UK base in Gloucester, Light Land is the world’s largest metal composite component for commercial aircraft. Currently, aircraft are made of 50% metal components, but replacing these metal components with TISICS’s lightweight and high-strength metal composites, aircraft can become lighter and more fuel-efficient.

A TISICS composite part weighing the same as a packet of crisps (36g), will be able to carry an astounding 5,000kg. The metal composites technology, applied to landing gear, claims to reduce carbon emissions by 9m tonnes annually, and save airlines £650,000 in fuel costs per aircraft per year. TISICS says that by replacing more traditional metal components with metal composites, the aerospace industry can slash carbon while creating 240 UK jobs by 2028.

Wing of Tomorrow’s 17m wing skin

Since 2018, a team of engineers at the National Composites Centre (NCC) in Bristol have quietly toiled away on a new composites deposition process: a fully automated, wing skin lay-up using novel high-rate deposition technologies. By the end of 2022, they had achieved a world-first, full scale 17 metre integrated wing skin infused in a single step. This is part of Airbus’s Wing of Tomorrow programme.

Composite materials enable wing components to be fully weight-optimised and produced with heavily reduced or eliminated sub-assembly and post-manufacturing costs. They also enable faster production cycles. The NCC was tasked with developing technologies and processes to produce three, full-scale, wing cover demonstrators.

The new deposition technology was designed to specification and supplied by UK automation integrator Loop Technology with collaboration from Güdel and Coriolis. It comprises two bridges, weighing 45 tonnes and 24 tonnes, 7m high by 13m wide, running along a 26m track. These bridges position automated end-effectors to enable cutting and deposition of dry fibre materials to high levels of quality and speed.

The automated process begins at a 20-metre table positioned inside the cell where an ultrasonic cutter profiles the carbon fabric to shape. An algorithm then selects the correct end-effector to pick the material up and then lay it onto the tool. Once lay-up of all the plies, processing and integration is complete, the component can then be infused with resin and cured.

For Wing Cover 3, the complete ply stack of dry fibre piece parts – approximately 170 individual dry fibre pieces – was deposited using the NCC’s Ultra High-Rate Composite Deposition, with no manual intervention. The real wings that will use this process will be incorporated in the next generation of single aisle aircraft, the timing of which is unknown.

Recyclable fibre tape for more sustainable composite manufacturing

The Multipurpose Fibre Reinforced Thermoplastic Tape (FRTT) Development Cell at the University of Sheffield Advanced Manufacturing Research Centre is being funded by a £1.7m grant from the Engineering and Physical Sciences Research Council. Such a material has huge potential. While aircraft are using more composite materials to reduce weight, their recyclability has remained frustratingly low. Sustainable thermoplastic composites are exciting due to their ability to be recycled, re-moulded and reused time and time again – once perfected.

“With regards to recycling, thermoplastics can be ‘remelted and remoulded’, making it far easier to recycle these materials over thermosets. You usually keep the fibre in the polymer, as it provides the strength,” said the FRTT cell project lead at the AMRC.

ATI’s Destination Zero

The ATI launched its Destination Zero programme in 2021 to achieve net zero carbon emissions for commercial aircraft by 2050, supporting the industry in sustainable design, manufacture, assembly and operations of future aircraft. Its three pillars are to focus on developing 1. Overt zero emission flights, using new propulsion like hydrogen, 2. ultra-efficient aviation, using existing engines that are more efficient, such as Rolls-Royce’s UltraFan engine platform, and 3. enabling technologies, capturing lightweight components etc. 

Recently the ATI launched two new programmes, a hydrogen capability network and – of special interest to MTD readers – a new SME Programme to assist smaller companies – see below.

Elsewhere, Airbus has developed and recently manufactured a cryogenic superconducting electric propulsion system purposely built to aerospace specifications, that should transfer more current and therefore power in an electric powertrain. And Rolls-Royce recently completed a successful run of its UltraFan technology demonstrator at maximum power at its facility in Derby, using 100% SAF fuel.

Manufacturing and Engineering SMEs undecided about impact of artificial intelligence

Despite the significant rise in the profile of artificial intelligence (AI), the UK’s Manufacturing and Engineering SMEs are largely undecided about the impact it will have on their business, sector and jobs. The findings are taken from the latest independent research from Close Brothers Asset Finance and Leasing. 

Seven in 10 of respondents are of the view that AI will have a bearing on their business, but are undecided about the scale, with 25% (UK average: 20%) thinking it will have a large impact compared to just 6% (UK average: 9%) who say it won’t have a measurable impact. 

Q: How much of an impact, if any at all, do you think the increasing presence of artificial intelligence will have on your business?

Business owners are split about whether to incorporate AI into their business processes, with 47% (UK average: 41%) saying they will against 36% (UK average: 40%) who have no intention of doing so. The remaining 17% (UK average: 19%) haven’t yet made up their minds. 

The key question about potential job losses brought about by AI also divided the crowd, with 42% (UK average: 42%) saying AI will lead to large-scale job losses in their sector; 43% (UK average: 43%) are of the opposite view while 15% (UK average: 15%) are unsure.

While many see AI as a potential threat, more of the UK’s Manufacturing and Engineering SME business owners see the technology as something that will present opportunities for growth and employment in their sector than those who do not.

The business areas (in order) most at risk from Artificial Intelligence according to respondents are: 

1. Customer service

2.  Administration

3. Marketing

4. Operations

5. Accounting

6.  HR

7. Sales

8.  Legal

Our view

Matt Roper, CEO of Close Brothers’ Commercial Business, said: “Artificial Intelligence already impacts us on a daily basis in hundreds of ways, from route mapping to using chatbots to answer questions, and it’s only likely to become more prominent in the coming years.”

“Our research is telling us a number of things. Firstly, there’s an understandable lack of consensus about AI’s current and potential impact, largely because it’s only gained traction in the public imagination fairly recently. There’s also no agreed definition of what AI actually is.

“Secondly, there’s a recognition that it could present opportunities for firms to use AI to their advantage, particularly in those sectors that are more reliant on digital innovation.

“And lastly, firms aren’t yet sure quite how to incorporate AI into their business processes.”

🎧 Subcontractor gets a grip with ITC

Like any fledgling company, the wind of change can blow qui🎧ckly through a business, and this was certainly the case for Shropshire Precision Engineering (SPE) Ltd. Initially set up as a ‘part-time’ business, it wasn’t until Technical Director Robin Chisnall joined the Shrewsbury business in 2017 that the company set about upgrading its machine tool and cutting tool technology – with XYZ Machine Tools and Industrial Tooling Corporation (ITC) proving the partners of choice. 

As an engineer who has been in the industry for almost 50 years, Robin sold his previous business for a life of happy retirement back in 2016, but when he got the call from fellow Director and Company Founder Chris Mills only a year later, the love for the industry was too great a pull. Investment in XYZ machines has improved productivity and throughput, but its the reliance upon cutting tools from ITC that has delivered production consistency, impeccable surface finishes, and reduced waste and costs whilst making a major contribution to productivity improvements.

When the ISO: 9001 certified business was founded in 2014, the workload was primarily centred around the automotive industry. Nowadays, 90% of the workload is focused on serving the rapidly growing and high-demand semi-conductor sector. The company provides a complete manufacturing, cleaning, assembly and packaging service as well as testing and production control. As Robin recalls: “When I joined the company, it was primarily using cutting tools from distribution companies. The issue was a several-day lead time for some standard tools with no guaranteed delivery date. We often had to take jobs off machines because we didn’t have the tools available. Another area of frustration was in the cutting tools themselves. A repeat order for an end mill would sometimes be a different brand, coating or geometry – this completely ruined our performance and efficiency. I had worked with ITC in the past and I knew that their service, support and delivery times were second to none. They are also a UK manufacturer that can manufacture special tools as well as standard products. I called the ITC representative and we set about standardising our tool library and consumption.”

A lot of components produced at SPE are small delicate stainless and inconel parts. To machine these, SPE implements ITCs 5021 Series of long length centre cutting 5-flute end mills with harmonic fluting and the 5041 Series of 5-flute extended reach end mills. As Robin adds: “Instead of changing between roughing and finishing tools, we trochoidal mill with the ITC 5-flute Cupro coated tools at high speeds and feeds with a low depth of cut. The surface finishes are incredible and the tool life is 50% better than any tools we have used before. We have recently started three new machinists and they are all struggling to comprehend the remarkable tool life we get from the ITC end mills and the reduction in tool changeovers.”

The tool life is a huge benefit to SPE, as are the improved surface finishes. “Before we started using ITC tools, surface finishes were inconsistent and we used to undertake significant hand polishing – this is no longer the case. This is saving our company a lot of labour hours every week.”

From a productivity perspective, the range of ITC trochoidal 5-flute end mills and also the 2152 Series of 2-flute ball nose end mills that are used from 1 to 8mm diameter for steel machining, have improved throughput significantly. As Robin adds: “All of our jobs are small volumes, so we can’t always track cycle times. However, when we first moved cutting tool suppliers, there were several jobs with 20 or 30-minute cycles that were reduced to less than 10 minutes with ITC tools.”

As well as using a complete array of ITC’s UK-manufactured cutting tools that range from end mills and drills through to taps and reamers, the Shropshire manufacturer has also invested in BIG KAISER tool holders from ITC. 

Alluding to this, Robin adds: “When we moved to ITC, we could conduct trochoidal milling at much higher feeds and speeds. However, the increased cutting forces were pulling tools from our milling chucks. To retain and extend these productivity gains, we needed high-quality chucks. We spoke with the ITC engineer and we bought the BIG KAISER Hi-Power BBT milling chuck with dual face and taper contact. The slim-line design gave us the reach we needed and the clamping forces eliminated tool ‘pull-out’. Additionally, the BIG KAISER chucks improved our rigidity and stability, this allowed us to run our ITC tools at even higher speed and feed rates.”

Alluding to the quality of BIG KAISER toolholding systems, Robin continues: “We have a lot of tight tolerance work and one job requires a series of 6mm diameter reamed holes at a 70mm pitch. We would have to do test runs on parts like this to avoid scrap. This deviation was not down to the machine or process reliability – but the toolholders. To eradicate this issue, ITC suggested we try the BIG KAISER MEGA New Baby Chuck for drilling and reaming the holes. We trialled a reamer with the new MEGA New Baby Chuck and it was reaming to a concentricity and precision level within 3µm. The runout of the previous chucks would never have held such tight tolerances.”

Concluding on the overall service from ITC, Robin says: “We have guaranteed next-day delivery on standard products, excellent technical support and an unfathomable diversity of special products. In fact, with every special tool, ITC will create a product code. This means that we can order the specific code and we will get repeat orders of our special tools that are all manufactured in the UK. This consistency is of critical importance to us. Some of our parts have a value that exceeds £12,000 – to scrap one of these parts because of tool ‘pull-out’, or the run-out on a precision feature is outside tolerance due to an inferior collet is not acceptable for our business. That is why we have chosen ITC as our cutting tool partner.”

🎧 SMEs need financial help and an industrial strategy to support manufacturing recovery

Tata’s £4bn battery gigafactory and a £600m investment in BMW’s MINI factory headline big investments and rising orders across manufacturing in 2023. But the pincer effect of high inflation, high interest rates and high demands from recovering OEMs is putting cash pressures on SMEs. Can they get the help they need to service the recovery and benefit from it, asks Will Stirling

2023 was a year of strained recovery for the manufacturing sector. After severe component supply delays caused by fallout from the Covid-19 pandemic and the Russia-Ukraine War, 2023 edged back to normality – or a new, more expensive normal. But as the orders returned, crippling inflation and high interest rates bit hard. Tata Group delivered a wonderful present to British industry and the beleaguered Tory government when it confirmed it would invest £4bn in a new battery gigafactory in England, understood to be Somerset, with a £500m Treasury subsidy. With the near collapse of Britishvolt’s plan to build a gigafactory in Blyth and no news of the proposed West Midlands battery plant, the huge investment brings jobs and shows the UK’s viability to other volume electric vehicle battery makers. The big question: will the plant manufacture high-value battery components, or simply be a giant assembly plant for parts made abroad?

Staying with automotive, BMW announced a huge £600m investment in the MINI factory near Oxford to build electric cars. Production of two new electric MINI models is due to begin in 2026. As well as safeguarding the 4,000 jobs across Mini’s two UK sites, it was a relief to many observers who thought that post-Brexit BMW might offshore Mini production wholesale to Germany. It could be interpreted as a strong example of recent efforts, led by Germany, for easier trade arrangements between the UK and the European Union.

Sustainability and carbon reduction have returned as the number one business agenda, or number two after surviving inflation. Whatever your politics on fossil fuel and renewable energy, drilling approval of the Rosebank oilfield will also bring hundreds of jobs and a fortune in tax revenue, although the government showed ill-judged myopathy when setting a low guaranteed price for new wind power electricity prices. This meant just a few MW of new wind farm licenses were purchased in the latest offshore wind auction with Greenpeace dubbing it ‘the biggest disaster for clean energy policy in the last eight years’. Also in September, business group Make UK’s annual analysis of manufacturing numbers showed the UK is now the 8th largest manufacturing nation in the world. The media and social media went berserk, with ‘8th biggest’ setting LinkedIn alight. The UK’s margin over the new 9th placer, France, is small and the numbers are fluid, meaning while it’s cause for celebration it should not be taken as a long-term sign of ladder climbing.

The aerospace industry is recovering strongly. Global aviation capacity should exceed its 2019 record by the end of 2023, as the airline industry returns to long-run econometric trends. Passenger demand recovery as measured by ‘revenue-passenger-kilometres’ is, industry insiders say, largely due to the reopening of China’s domestic market. Aerospace business group ADS says there is now a record backlog of orders for aircraft and engines – over US$1 trillion out to 2031, meaning aircraft production is ramping up to previously unknown highs.

Airbus directly employs nearly 12,000 across all its manufacturing divisions and was on track to hire hundreds more in 2023. The company indirectly supports 79,000 jobs in the UK. “Like many in the industry, Airbus has had to navigate operational complications stemming from lagging post-Covid factors, including availability of material and skilled resources,” is what Paul McKinlay, Senior Vice President and Head of Wing Major Component Assembly, Airbus told MTD exclusively. “[However]… our supply chain is still subject to the challenges of recession, inflation, energy price volatility and of course, geopolitical tensions.

Saying that, we have progressed well across all business lines in 2023 and the demand for commercial aircraft remains strong as evidenced by more than 800 orders announced at the Paris Air Show this summer.

He adds: “Airbus continues to invest in our supply chain network, spending £3.9bn on goods and services last year in the UK with around 3,000 suppliers right across the country, 50% of which were SMEs. This gives us a solid degree of resilience in our supply chain as we execute our ramp-up on all commercial aircraft programmes (A220, A320 family, widebody family). We announced that we intend to ramp up our A320 wing production in North Wales to an unprecedented 75 aircraft per month in 2026.”

All good news, right?

SMEs squeezed as production rates ramp-up

The flipside of much higher production rates is pressure applied to SMEs in the supply chain – including MTD’s readers. “In the supply chain, surviving the Covid-induced downturn was difficult; but as always predicted, for many smaller businesses surviving the upswing, with all the cash demands that brings, is at least as tough,” says industry veteran Andrew Churchill, of JJ Churchill in Market Bosworth. “Having cut employment during the downturn, a fifth of suppliers are now reporting vacancies and they have difficulty recruiting. There are currently 90,000 vacancies in the UK manufacturing sector.” He adds: “This, together with the much higher borrowing costs, higher energy bills, escalating raw material costs and often deferred capex investment means that many of the aerospace primes’ suppliers will be the weak link when it comes to delivering the rate ramp-up.” It’s a sadly familiar trend – the boom-bust cycle of the industry, while arguably far smoother today than the giddy 1980s-2010s, means SMEs struggle to grow into mid-sized companies with the critical mass and diversification to survive a big downturn without shedding staff and expertise.

Despite the high vacancies, manufacturing created a lot of jobs in 2023. BAE Systems is on track to hire more than 2,600 new apprentices and graduates in 2023, a 43% increase on the careers intake in 2022. Manufacturing in the UK still employs 2.6 million people, which has remained reassuringly static for several years. It could be higher if the labour market was blessed with the skills and experience many engineering companies need. 2023 was disappointing for many companies and industry advocates who desperately want an industrial strategy with a long-term, 10+ year horizon. This elusive strategy, and a minister for manufacturing, have been heavily campaigned for on social media by people including Andrea Rodney, Managing Director at Hone-All Precision in Leighton Buzzard. Sadly, and staggeringly, the government “still fails to recognise the damage that the lack of a cogent long-term industrial strategy does to sector investment. The UK is the only major economy not to consider this as important,” Andrew Churchill says.

In the automotive industry, all the numbers are up, up, up on 2022 – and praise the Lord. In August, the latest month with complete numbers, total car manufacturing was up nearly 12% on 2022 (to date), and car exports were up 14.4%. Commercial vehicles up 14.4% on 2022 to August, and exports were up 23%. Over 450,00 cars were built here in the first six months of 2023 (Source: all the SMMT). As reported in October, the rapid expansion of clean energy, electric cars and heat pumps means that energy-related CO2 emissions are likely to peak by 2025, according to the International Energy Agency.

Lies, damned lies, and statistics. One can always find numbers to support your argument – or discredit it. While recovery is still the watchword for 2023, some numbers tell a different story.

Figures and news from automotive, aerospace, medical and oil & gas sectors support the upswing. But the number of companies trading in manufacturing, across all sub-sectors, has fallen in 2023 since 2021 by 3% or 4,265 companies. That’s a lot of firms to lose in two years. The biggest category for insolvencies: “Manufacture of fabricated metal products; except machinery and equipment. This is down 15% or a whopping 4,195 companies. It doesn’t quite match the message of record order books in aerospace (aircraft and engines) and the storming return in automotive as seen above, as well as the high growth in electric vehicles – 23.2% of all new cars in the UK are either electric or plug-in hybrid,” says ZapMap.

The curate’s egg: Manufacturing in 2024

So will 2024 fare better than 2023?

Paul McKinlay emphasises Airbus’ strong pipeline, as it ramps up to 75 aircraft per month. “In being clear and communicative with our supply chain network about this pace, we’re laying the groundwork for ensuring quality performance and missing parts reduction.” But he adds: “However, the challenges we’ve seen in 2023 are likely to bleed into 2024. We need to see greater support for our UK SMEs partners, giving them the financial security they need to scale operations. That’s how the UK will be able to drive competitiveness over the next decade.”

Andrew Churchill’s 2024 glass is half-full, as he concludes: “Despite the ‘curate’s-egg’ that UK manufacturing represents, I remain optimistic. For the first time in six years, we have climbed the world ranking of manufacturing nations from 9th to 8th – overtaking France, 41% of all UK R&D is from the manufacturing sector and our goods account for an amazing 49% of total UK exports. Just think what we could achieve with a long-term industrial strategy, affordable and secure industrial energy, a full review of the Apprenticeship Levy and a clear path to helping manufacturers de-carbonise!”

Just think…. Are you listening Sir Keir Starmer?

MACH is on the horizon

MACH 2024 is just around the corner with the exhibition kicking off from the 15th to the 19th of April, so MTD invited James Fudge from the MTA to the studio to give us an update on the UK’s premier manufacturing exhibition. With less than six months to the exhibition, the anticipation is building.

Speaking with MTDCNC, James Fudge says: “After EMO, many of our exhibitors can work out what equipment they will have on their stands at MACH 2024 – as it will have been showcased and tested on the European market. With Easter falling on the last day of March, the opening of MACH 2024 will be after the Easter break – this will be good for both exhibitor and visitor numbers.”

Looking forward to the event and discussing what will be new, James tells us: “One of the things we are looking at this time, is why do our visitors come to the show? We get a lot of visitors who say they only come to MACH, rather than any other UK exhibition. This is because they want to look at new technology and equipment and find out what is going on in the industry. Additionally, engineers are trying to find solutions, so what we’ve said is how can we signpost that in the main areas that people come to. For example, tooling accounts for 26% of our visitors and automation is a large part of our visitors requirements. We’ve always had automation throughout the show, but we want to put knowledge hubs in place so visitors can identify what they need based on their particular business. The knowledge hubs will signpost visitors to other exhibitors in the show that are showing that type of technology, they can go and get the answers.”

Expanding on the knowledge hubs, James says: “They are independently run in conjunction with the MTA and a lot of the High Value Manufacturing Catapult Centres. If you go to the additive manufacturing knowledge hub or the automation knowledge hub – they will be run by the MTC. The tooling knowledge hub is being run by the AMRC and we will also looking at an energy reduction hub. The idea is that you go along to the hub and there will be some examples of the different types of technology in that area.”

Discussing the return of exhibitions after the Covid pandemic, James continues: “We opened sales for MACH 2024 at the 2022 show, and we came away with more bookings than we’ve ever done before. What was interesting about the last show is that visitors and exhibitors were saying ‘I haven’t seen you for four years’, this is quite interesting as some people only ever see each other at MACH. MACH is not a five day show, it’s a two-year cycle and the show is critical in keeping those relationships alive over the two-year cycle.”

Alluding to new exhibitors and updates for the show, James continues: “We have quite a few new companies exhibiting at MACH following visits to the show in 2022. It’s also fascinating to see the technology change from the same exhibitors from one exhibition to the next. It shows the speed of change in the market. I also think the knowledge hubs a large part of our show, as will our seminar speakers talking about the rate of change.”

Commenting upon the Engineering Supply Chain Show running concurrently with MACH, James adds: “There was a soft launch last year and this year it’s going to have its own hall, so it will sit in Hall 7 as a three-day show. It is the only co-located show with MACH and this exhibition is for showcasing the UK supply chain. So, companies have to be UK-based and it’s about really looking at the capability and capacity of the UK. This is because what we find is a lot of big companies come to our show such as OEMs in the auto and aero industries, their procurement teams turn up but sometimes they are not looking to invest in new equipment they are looking for capacity – that is what we are trying to showcase. We have the community in place for one week, why wouldn’t we do that?”

The MTA and the MACH exhibition is renowned for its MACH dinner, discussing this James says: “As we have the whole manufacturing community and all of the MTA team there, it makes perfect sense to have the MTA dinner at the event. This will be held on Thursday evening at the Vox, which is on-site of the NEC, so people can walk straight to the dinner from the exhibition – and tickets are available for engineers to make the most of the networking in a less formal setting.”

🎧 The state of play

At the recent EMO exhibition, there was a lot more on offer than innovative products and technical insights. Here, we provide you with an overview of the global machine tool market, which was presented in Hannover by CECIMO – The European Association of Manufacturing Technologies at a press conference during the exhibition.

At the conference, there were representatives from all the major machine tool associations – whose manufacturers account for more than 80% of global machine tool production. At the gathering at EMO, the respective associations demonstrated their resilience and strength in the face of a wide range of global challenges. Despite a stable outlook for 2023, projections for the global machine tool industry are tempered by various international and economic challenges. Building on the collective strength of the sector; collaboration, innovation and adaptability will remain key as the industry continues to navigate this evolving landscape.

The event united machine tool industry leaders from the United States, China, Japan and Europe. The opening remarks at CECIMO’s Press Conference at EMO Hannover 2023 from Dr Heinz Jürgen Prokop, CECIMO’s President were: “At a time of profound political and economic uncertainty, the promotion of international cooperation is imperative.”

Mr Marcus Burton, Chairman of CECIMO’s Economic Committee, highlighted CECIMO’s commitment not only to lobbying for favourable conditions for the sector but also to fostering international cooperation with machine tool associations around the world. In that context, he also unveiled key insights from CECIMO’s recently published Global Machine Tool Report 2022, which could not have been produced without such cooperation. Based on the latest database update, Mr Burton highlighted that Global MT (machine tools) production reached a level of €79.2bn in 2022, reflecting an annual production increase of 11.9%.

In the same year, MT production in the CECIMO countries recorded an increase in production of 12.8%. With a level of €25.3bn, CECIMO maintained its share of 32% of global machine tool production. On the consumption side, CECIMO countries accounted for almost a quarter of global machine tool consumption, with a total value of around €18.7bn in 2022, a 25% increase compared to 2021.

During his presentation, Mr Burton also revealed the latest estimates for 2023 for global and European production. While he highlighted that MT production in the CECIMO countries is expected to grow by around 5.5% to reach a level of almost €27bn in 2023, global production is expected to remain more stable, slightly below the 2022 level. In his concluding remarks, he pointed out that: “In light of current developments, we have slightly downgraded our expectations. Nevertheless, we remain optimistic about the positive growth in European production in 2023 and our initial indications for 2024 are positive”.

However, he also highlighted the significant challenges on the horizon, including the headwinds of slowing global economic growth, rising interest rates and geopolitical shifts resulting from the ongoing conflict in Ukraine. These factors collectively inject a notable degree of uncertainty into the short-term demand landscape for the machine tool industry.

In reference to the Chinese machine tools sector, Mr Mao Yufeng, President of China Machine Tool & Tool Builders’ Association (CMTBA), pointed out that: “From January to July 2023, sales of metal cutting machines dropped by 4.3% to USD$10.76bn compared to last year. On the other hand, sales of metal forming machines went up by 6.9% to USD$6.16bn”. He also stated that 2023 has witnessed heightened endeavours in industrial restructuring and shifts within China’s machine tool consumer market. Among others, this includes a decline in overall automotive production, but a notable increase in the use of new energy vehicles. In addition to shifts in consumer markets, he highlighted several significant challenges that contribute to the uncertainty surrounding the outlook for the machine tool sector. These challenges include a fragile economic recovery, persistent inflation, financial market instability and increasing debt pressures.

Looking at the Japanese metal cutting machine tool sector, Mr Kazuo Yuhara, President of Japan’s Machine Tool Builders’ Association (JMTBA) highlighted remarkable growth for the Japanese metal cutting machine tools sector in 2022. Total orders surged to a record-breaking Yen JPY 1,759.6bn, a 14.2% increase on the previous year. Production of metal-cutting machine tools increased by 20.5% in 2022 over the previous year to JPY 1,078.8bn, with a strong growth trend in both export and import levels. Looking at the most recent period of January to July 2023, he noted the decline in order volumes for metal-cutting machine tools. However, he highlighted positive expectations for the impact on demand of investments in green, digital and resilience-related areas.

Reviewing the American Machine Tool Industry, Mr Douglas K. Woods, President of AMT – the Association for Manufacturing Technology in the USA, emphasised continued stable conditions for the American Machine Tool Industry in 2023 and 2024. This follows a year of near-average consumption of USD$9.6bn in 2022. In 2023, the impact of tightening US monetary policy has become apparent, leading to a slight decline in machine tool consumption. However, indicators for 2024 suggest a recovery in machine tool production and imports, while exports stabilise, leading to an increase in consumption.

🎧 Siemens slashes machine development time for PTG Holroyd

As a machine tool builder, Rochdale-based PTG Holroyd is regarded as a world leader in the creation of highly sophisticated rotor milling, rotor grinding and friction stir welding machines. With three divisions in the company, each with a highly sophisticated niche, the manufacturer has further evolved its longstanding partnership with Siemens following the arrival of a new CNC control system for its machine tools.

As a business, Holroyd has been producing machines in Greater Manchester since 1860 and is a world leader in the design, build and supply of high-precision gear, rotor, screw and thread milling and grinding machines for the manufacture of ultra-precise helical components – and it is here that the relationship with Siemens is reaping rewards.

Commenting upon the evolution of the relationship, PTG Holroyd Sales Director, Mr Mark Curran says: “We have worked together with Siemens for more than 25 years. When we discussed with Siemens that we were creating a new design of machine, they informed us that there was a new control system coming to market.”

The new machine development is the PTG Holroyd HG350-G helical grinding centre for the production of gears and threads up to 350mm in diameter. The first machine tool from PTG Holroyd to use Siemens’ new SINUMERIK ONE future-proof CNC, the HG350-G offers greater levels of flexibility for manufacturers of precision spur gears, helical gears, worms, screws and rotors. The HG350-G is a self-contained production cell that features an extended machine bed to accommodate screws and worm shafts of up to one metre in length with uncompromising levels of precision finish.

“When we discussed with Siemens that we were creating a new design of machine, they informed us of the new control and we decided it was a good time to partner with Siemens with the SINUMERIK ONE control,” says Mark Curran.

Looking at the reasons for working with Siemens, Wayne Hallam, a Project Engineer at PTG Holroyd says: “We chose to work with Siemens because of the support that they give us. Additionally, the system enables us to combine many different software suites into one package – as it is a modular system. With the power of the Siemens Digital Twin ‘Create MyVirtual Machine’, it is easy to commission all software packages off-line and then prove them on our machines once they are built.”

Create MyVirtual Machine is a virtual CNC with behaviour identical to that of an actual CNC within the machine. Not to be underestimated, a CNC is adapted to a particular machine tool based on several thousand items of machine data – and this is where many simulation suppliers fall down. As CNCs in their software solutions only simulate to a sufficiently accurate degree, the testing of CNC programs is only possible to a limited extent – and the measurement of runtimes is impossible. Create MyVirtual Machine from Siemens has a clear advantage, as CNC programs are tested with exactly the same CNC setup as in the machine. This enables the CNC program runtime to be measured with an accuracy above 90%.

As Mark Curran continues: “We wanted to future-proof the machine because of the software we are developing. Our platform enables multiple suites of software on the machine, so we needed a very powerful system. Currently, SINUMERIK ONE is the most powerful control on the market.”

Discussing this future-proofing, Siemens Application Engineer Garry Mepham says: “It’s future-proofed because we offer enhanced connectivity possibilities with additional PROFINET interfaces, OPC/UA interfaces and increased performance. We can do this as the CNC is now up to 50% more powerful than the previous control and the PLC is 10 times faster. This is thanks to the newly integrated state-of-the-art 1500 PLC. SINUMERIK ONE boasts compatibility with previous versions, so from an operator point of view it is very familiar – it’s just the interface that is slightly enhanced. It still boasts all of the open architecture and possibilities that people come to know with Siemens and this leads to the possibility to program modular design concepts that are important to modern machine tool builders and their concepts. SINUMERIK ONE also boasts increased security in terms of the connectivity between the networking components in the system and the HMI on a control panel as well as external devices such as servers, PCs and the internet with completely encrypted security that is certified for the modern environment.”

As Mark Curran continues: “With previous machine tool developments, we have had to have the machine on the shop floor to start the software development. With the ‘Create MyVirtual Machine’, we have been able to almost completely create all of the software and the PLC software before the physical machine becomes available. This has reduced the lead time significantly.”

Siemens Application Engineer Garry Mepham adds to this, saying: “The digital twin forms part of the many digitalisation offerings Siemens has. In the case of SINUMERIK ONE, we have two products. These are ‘Create MyVirtual Machine’ and ‘Run MyVirtual Machine’. Create MyVirtual Machine is aimed at the machine tool builder and Run MyVirtual Machine has been developed for the end-user of the machines. With the digital twin, the key features of Create MyVirtual Machine are the ability to test the concept remotely through to safely develop and test the reaction, should a fault occur on the machine. This enables users to speed up the commissioning process by up to 30% if not more.”

“For the end-users utilising Run MyVirtual Machine, they can verify their toolpaths and machining processes by running this software package. This system gives operators confidence that when they verify a toolpath, they have a very accurate representation of the cycle time. This enables the user to be confident that when it is issued to the physical machine, the part is right the first time with no collision risk. Using SINUMERIK ONE in conjunction with Create MyVirtual Machine or Run MyVirtual Machine, some of the key benefits include a significant saving on resources. For example, we can do our testing, verification and development in a virtual environment rather than in a real machine, so energy efficiencies and cost savings are there to be made. These help machine tool builders achieve their sustainability goals whilst compressing product development.”

Concluding on the SINUMERIK ONE and its relationship with Siemens, PTG Holroyd Sales Director, Mr Mark Curran concludes: “The HG350-G doesn’t only bring new levels of flexibility to our customers but with the Siemens Sinumerik ONE control system – it represents a new era for machine tool manufacturing.”

🎧 People, Process, Principle

An aerospace parts supplier in Wichita, Kansas, US has built a business on the three pillars of People, Processes and Principles – and it is the VERICUT toolpath simulation and optimisation software from CGTech that helps support the second principle.

The company applies integrity and experience, consistent performance and clarity of purpose as words to live and work by, no matter what the vocation. They are the guiding philosophies behind Trinity Precision Inc.’s motto, ‘People, Process, Principle,’ and ever since founders David May, Steve Ford, Dave Tice, and Chris VanNover opened the company’s doors in 2014, they’ve stood by them.

“When we started Trinity, it was important that we establish the foundations needed to assure success for the company and its employees,” said VanNover, Trinity Precision’s Vice President of Operations. “One of these was the use of robust programming technology, which includes accurate, productive toolpath simulation. VERICUT has filled that role since day one.”

CNC Programming Manager Merritt Stuever has worked for the company for the past five years. Like VanNover and the rest of the company’s management team, he also has great respect for VERICUT. Including his time at Trinity Precision, he’s been using the product for nearly two decades. “After running a program through VERICUT, you’re not only assured that the G-code is consistent with a good part, but you also eliminate any chance of a crash,” he said. “Considering the cost of replacing a spindle and the machine downtime that comes with it, it’s a simple choice. VERICUT is a no-brainer.”

Trinity Precision is heavily into aerospace work and its customer list includes Boeing Commercial and Defense, Northrop Grumman, Gulfstream and Textron Aviation. These are OEMs with zero tolerance for deviation in part quality or missed deliveries. As such, strict adherence to established processes is critical, which helps explain the aerospace supplier’s early focus on ‘the three Ps’ in its logo, along with its reliance on sound programming.

VanNover explained that Trinity Precision president David May purchased an existing ‘mom and pop’ machine shop as a starting point for the new business. The previous owners were using a well-known brand of CAM software and had a single seat of CATIA from Dassault Systèmes that was gathering dust. May and his management team hit the reset button.

“We knew from previous experience that implementing change once you’ve reached a certain size can be difficult, so we took the opportunity early on to build everything right from the ground up,” he said. “We stayed with CATIA because that’s what most of our customers require. VERICUT does everything that we need it to do, and seeing as we were looking forward to a lot of new CNC equipment back then, also liked the fact that we can develop our own machine tool models. It gives you a lot of flexibility.”

Today, Trinity Precision boasts 32,000sq/ft of manufacturing space and a fleet of advanced CNC machinery. It has also enjoyed a four-fold revenue increase since those early days. VanNover noted that, like most in the aerospace industry, the pandemic-related slowdown in commercial aviation gave them ‘a pretty significant haircut’ over the past two years, but that tide appears to be turning, and Trinity’s 70+ employees stand ready for future growth. However, that growth depends on robust processes, something Stuever and the rest of the engineering team spend their days developing. Every CNC machine tool has a standard tool list, greatly reducing setup time and eliminating the chance that an operator will place a cutter in the wrong position.

In addition, all feed rates, cutting speeds and other machining parameters are similarly standardised within CATIA. Offline presetting is used, and many of the machine tools employ tool breakage detection for automated operation. Every job goes through VERICUT before leaving the programming office, a requirement that Stuever noted has saved the company countless hours of rework and even scrap.

“We’re mostly a high-mix, low-volume shop, so we might have a couple of dozen new part numbers in a week,” Stuever said. “Since none of us can read and visualise hundreds of thousands of lines of G-code, VERICUT is the best way to check for interference, gouging, leftover material, and any of the other everyday programming scenarios that can lead to a bad part or worse. And since you know the software will catch things like that, it makes the programming process both easier and faster.”

Stuever’s also quite pleased with CGTech’s support level. He’s taken several classes over the years and attended multiple VUE sessions (VERICUT Users’ Exchange). Because of this, he’s come to know many of the people in the software developer’s Irvine headquarters. “They’re very helpful and always take the time to make sure any issues or needs are resolved. As far as technical support goes, there are only two companies that I rank extremely high. CGTech’s one of them,” he said.

VanNover offered similarly high praise: “The rest of the management team and I have worked in shops where machinists were out there changing programs, selecting their tools and pretty much doing their own thing, but you just can’t operate like that anymore, especially with the available labour force. This is why we’ve taken most of that responsibility and put it in the programmer’s camp, making it critical that you have the right software tools. And so even from the very start, this was a non-negotiable aspect of our desire to lay the right foundation; VERICUT is a big part of that foundation.”

🎧 Thinking Big

Last month, MTD magazine visited RODIN Machining in Holland, a company that claims their entire customer process – from customer registration and work preparation to production and invoicing is almost 100% automated with sharp delivery dates. We went along to see what was behind this manufacturing utopia – it turns out that FASTEMS is a crucial factor in achieving this nirvana. By Rhys Williams

About an hour north of Amsterdam in the town of Opmeer is RODIN Machining, a Dutch contract manufacturer that is said to be the first fully automated turning and milling company in the world. To achieve its incredible levels of automation, the company has fully embraced robotisation, self-learning software and artificial intelligence. This was the perfect setting for RODIN and FASTEMS to host an Open House event to demonstrate what can be achieved with the visionary application of leading technology. Along with 300+ guests and dignitaries, MTD magazine couldn’t wait to take a look around!

A start-up business like nothing ever seen before, RODIN is aptly named after François Auguste René Rodin, the 19th century French sculptor who is considered the founder of modern sculpture. An artist with a craftsman-like approach to his work with a unique ability to model complex shapes – the parallels between the artist and the Dutch company are not coincidental. To celebrate the opening of the new facility, the company was presented with one of Rodin’s most famous sculptures, ‘The Thinker’. And this is where the story starts….

The Thinkers and the Drinkers

Founded by Gem Bot, Dennis Oud, Paul Mooij and Ruud Appel, the expertise of the entrepreneurs resides in software and data engineering and subcontract sheet metal manufacturing. As owners of a successful sheet metal business, the entrepreneurs asked why the sphere of machining had yet to reach the levels of end-to-end automation found in the sheet metal industry. The concept was borne, and the entrepreneurs set about turning the idea into a reality.

Coming at the challenge without machining expertise provided a fresh approach that was met with an element of bemusement at EMO 2021. The team laid out their vision and spoke to several exhibitors at the show – and the vision of an automated factory was met with an almost dismissive condemnation. The entrepreneurs presented their plan to Mazak at EMO and confirmed that if they would support RODIN’s journey, RODIN would buy their machines. As RODIN Director Ruud Appel tells MTD magazine: “We wanted to create an autonomous factory without people and only robots. Everyone told us that it wasn’t possible, but we wanted to stretch the bounds of what was possible. So, we started gathering a group of leading suppliers like FASTEMS in CNC automation and asked them searching questions – ‘Have you thought about doing it like this?’ and ‘Why do you always do it like that?’. We wanted to know why everybody thought that historical processes were the only way to proceed. We really wanted to change the mindset.”

Without a customer base or a factory to work from, RODIN decided to take the ‘leap of faith’. “We needed machines that were as versatile as possible and we needed FASTEMS to create the integrations and automation with cutting tools, tool data, workholding, grippers, chucks and software like ERP and CAD/CAM. RODIN and FASTEMS worked together to calculate how to get the most machines into the factory space and create the optimal workflow. There were many iterations and when we were settled upon a final design layout, we set about building the factory and teamed up with our partners to realise the project.”

“We are all about partnering. We needed machines, automation, robots and software – and software and database integration was one of the most important things,” says fellow director Paul Mooij, who is truly superb with software, AI, data management and creating one big loop. “FASTEMS, Mazak and our other partners have done this hundreds of times before – but we wanted to make it smarter than ever before. Smart in a way that all systems communicate with each other. We have only improved upon the existing tricks, not developed them. Along the way, we were met with a lot of ‘you can’t do that’, ‘that is not possible’ and ‘it’s always been done like that’. Our team and our partners agreed that every time we heard those negative phrases, the perpetrator would have to buy the drinks. A lot of people bought beers –which usually yielded solutions, and we managed to change the mindset and have the project delivered.”

How it works

According to RODIN, the process is as simple as signing up as a customer online and then uploading your part design. Talking us through the system, Ruud says: “Customers can upload their 3D design and a PDF file with the tolerances 24/7 and then select material type, quantity and delivery date. A quotation will be delivered in 30 seconds. Upon quotation approval, automated manufacturing starts immediately. Your project is put into the ERP system and as automated as possible, it is turned into machine and robotics programs by the CAM engineers. There are limitations on part sizes, and we typically produce volumes from tens to thousands – but that is it. We are not about shaving seconds off volume production, but creating a steady high-mix flow that will run 24/7 unmanned. While a typical CNC machine runs 1500 to 2000 hours a year, the FASTEMS logo says ‘8760’ referring to the hours in a year – and that is where we want to be with our spindle hours.”

  As a start-up, RODIN already works with a wide variety of clients in the construction, machine building, coachbuilding, furniture manufacturing, shipping, automotive industry and petrochemical industries. The components are as diverse as you could imagine, producing everything from simple to complex with a huge volume, material and dimensional mix.   

What’s on the shop floor

Factory construction only started in September last year with rigging for the machines commencing in January 2023. Now, the new shopfloor has a state-of-the-art FASTEMS Agile Manufacturing System (AMS) running down the centre of the factory, capable of highly autonomous production in advanced milling and turning applications.

Material is purchased in pre-cut billets and manually loaded to pallets that have jig plates to accommodate different-sized billets. The pallet then enters the AMS where material is stored until it is called by Fastems’ Manufacturing Management Software (MMS) as part of a production order. The FASTEMS system will then determine which machine is available and then deliver the raw material pallet to it while set-up changes are completely automated. Discussing this, Ruud adds: “We have to have human interaction while creating the CAM file, loading/unloading the AMS and also pre-setting the cutting tools – but more than 90% of the process is automated.”

Once parts are programmed with CAM software, they are dropped into the FASTEMS MMS that will automatically generate a production plan based on order due dates, inventory balance or recurring batch runs to ensure the timely delivery of parts. The MMS forecasts the optimised production workflow, days in advance by preparing resources to minimise machine waiting times and WIP. The MMS also provides real-time production monitoring, tracking key performance indicators from OEE, machine tool utilisation and available resources.

Once the CAM programme is in the MMS and the billets are loaded, the parts are then scheduled for production. When called, a pallet capable of holding up to 1000kg will travel through the 512 pallet FASTEMS AMS to one of the machining cells. The AMS is configured with a two-machine milling cell on one side of the AMS and a two-machine turning cell on the other side.

The milling cell incorporates two 5-axis Mazak Variaxis C-600 machines that receive components from a robotised part-loading cell: the universal smart fixture devices are automatically prepared and delivered by another robot to the Variaxis machines to eliminate human interaction. The cell has a complete range of SCHUNK robot grippers that are automatically changed depending on the workpieces being scheduled and delivered to the machine.

You would typically think that this level of automation has everything covered, but it doesn’t end there. The system is capable of automated re-gripping for flipping the parts over from OP10 to OP20 – before re-entering the machining cell for complete 6-sided machining. Of course, RODIN doesn’t want to have an operator manually inspecting the parts, so intermediate probing and adjusting the finishing pass is typically part of the cycle. Once the part is completed, it is returned to its pallet. When the pallet is full, it is returned to the FASTEMS AMS where it will reside until its scheduled delivery date.

Like always, the cutting tools must be monitored and changed with optimal frequency. Here, RODIN opted for a fully integrated tooling solution where the Variaxis’ 30-position ATC acts as a short-term buffer and the robot proactively loads/unloads tools from an 800-position long-term storage unit that is part of the FASTEMS AMS. Once tools have reached their designated machining hours, they are automatically moved to a tooling station where they are manually removed, replaced, re-set and re-installed for the robot to collect new tools.

On the opposite side of the FASTEMS AMS is a two-machine turning cell with Integrex i-350H S turning centres supported by a FANUC robot. Configured slightly differently from the milling cell, the robot runs between the two machines loading/unloading components, cutting tools, interchangeable chuck jaws as well as its different gripper configurations to produce a wide array of parts. The cell will also automatically machine soft jaws to accommodate pending jobs.

Whilst the FASTEMS AMS at RODIN currently has a two-machine turning cell and a two-machine milling cell on each side of the AMS, the system has been configured for RODIN to add four additional machines on each side. With the next phase of ordering machine tools set to commence in 2024, RODIN will determine the type and size of Mazak machines to add to the FASTEMS AMS based on its clients and workload – all of which is being continually monitored by the ingenious FASTEMS MMS software the company utilises. Whilst the four entrepreneurs remain tight-lipped about the future of the business, not wanting to divulge more than the obvious plans for filling the Opmeer facility to its capacity of 12 machines that will run virtually unmanned 24/7 – it is evident that RODIN has sculpted a blueprint for automated success with FASTEMS that is completely scalable. In the next issue of MTD magazine, we speak with FASTEMS Sales Director for EMEA, Leigh Tricklebank to discover what the pain points are for subcontractors – and how to overcome them.

Choosing the right cobot

Paul Richards, Global Customer Coordinator Europe, Cobot Market, FANUC Europe

When the International Federation of Robots (IFR) first started collating collaborative robot data in 2017, this new breed of robot had a market share of just 2.8%. The IFR’s latest report showed that by 2021, that figure had leapt to 7.5%, with the number of newly deployed collaborative robots growing by 50% year-on-year to 38,966 units globally.

Cobots are gaining popularity for several reasons. Firstly, they provide a solution to many challenges that manufacturers are facing. In terms of flexibility, the cobot sits between an industrial robot and a human. This agility is valuable for accommodating shorter product lifecycles and the high mix and low volume approach to manufacturing.

As demand for cobots has soared, the number of players in the market has proliferated and there are now over 60 cobot manufacturers worldwide. Whilst more competition can mean greater choice and better value for customers, it can also mean more confusion. This is particularly salient when you consider that cobot sales in the UK are being driven by SMEs, who seldom have the in-house resources and expertise to thoroughly assess numerous different makes and models. To aid the decision-making process, FANUC has compiled a checklist to help first-time buyers navigate the complexities.

1. Establish the business case

Determine whether your operation would benefit from a cobot. Start by identifying the pain points hindering growth. If staff reliability, RSI, health & safety, a lack of labour, or the limitations of hard automation are on your list – cobots are a route worth exploring.

2. Identify potential applications

The next step is to identify the applications associated with these pain points. What are the tasks that are causing RSI? Which tasks don’t humans want to do?

3. Evaluate the applications

Score each application based on the following considerations: Is it a precision task? Are there uncomfortable motions involved? Does it result in high rejection rates? Does it involve heavy loads? Is a constant human presence needed? Does the human operator add any value? What speed does the task need to be performed?

4. Cover off safety concerns

Assess safety. Does the cobot need to be guarded or part-guarded? Part guarding or other safety devices can be employed to enable cobots to work alongside humans at higher speeds. However, if the application requires full guarding, making it less flexible and adding to the cost, a cobot may not be the right solution.

5. Protect your investment

The IFR considers the average lifespan of a robot to be 12 years. To protect your investment, buy from a brand that is still going to be around in 13, 14, 15 or more years. Ask potential suppliers for the predicted life of their cobot.

6. Calculate payload

and reach

Do not go too low on the payload. Don’t assume that if a cobot has a payload of 5kg it can lift an item weighing 5kg. To work out your payload requirement, calculate the total load on the end of the arm (part + gripper + fingers etc) whilst taking into account offset payload and inertia. When calculating reach, bear in mind that working at full reach limits the cobot’s movement in the robot’s wrist, so build in additional margin.

7. Select sensors and ancillary equipment

If your application requires 2D or 3D vision, consider where you want the camera (remotely or on the cobot). If the cobot will always pick from the same area, a camera is best mounted over the pick area.

8. Evaluate your environment

If you want a cobot in a food production environment, you will need to think about IP rating and washdown protection. If the cobot is intended for use in a dusty or dirty environment, you will also need a high protection rating (IP67 or above). When enquiring about IP ratings, make sure that they apply to the entire unit (including the controls), not just the arm.

9. Consider connectivity

Does the cobot need to communicate with other equipment, such as CNC machines, part feeding systems, grippers or vision systems? If so, specifying your cobot with the same communication protocol as peripheral equipment will save cost and integration time.

10. Plan for the future

Finally, think about how flexible the cobot is for meeting your future needs. Will it be able to accommodate new applications and growth? Does it have software that can be updated and supported? As well as driving productivity, a positive experience will pave the way for further automation of more profitable applications and inspire employees as you continue on your automation journey.

🎧 Prima packs a punch

Prima Power, the brand born from the union of two industry leaders Prima Industrie and Finn-Power, has been synonymous with the sheet metal industry for over 50 years. MTD Magazine visited the factory in Seinäjoki in Western Finland to see how this sheet metal powerhouse manufactures machines that lead the industry in innovation. By Rhys Williams

Founded in 1969 as a subcontract manufacturer, Finn-Power Oy evolved down the generations to become one of the industry’s leading manufacturers of punch presses, press brakes and automation systems. With hundreds of UK installations over the years, legacy customers will be pleased to know that after our visit, the Finnish company of the Prima Power brand is bigger and better than ever before – and legacy customers can still be serviced and supported extensively in the UK.

As a global group, Prima Power has eight factories and R&D centres, employing more than 1900 people to develop the next technologies, manufacture existing product lines and service and support the 15,000+ machines installed around the world. Located in the South Ostrobothnia region of Finland, Finn-Power Oy started as a subcontract business and developed the first crimping machine for the hydraulic industry in 1973. As a serial entrepreneur, company founder Jorma Lillbacka needed sheet metal parts for his crimping machines, and rather than buy a machine or subcontract manufactured components – he developed a turret punch press in 1983. After selling the first turret punch press machine at a Paris exhibition, the company built more machines and developed its first automatic material handling system in 1985, which was rapidly followed in 1987 by its first combination laser and punching machine with stacking and sorting systems following in 1988. Then its first ‘Night Train’ FMS arrived in 1990. This global growth trajectory earned the company a Finnish Export Prize from the Finnish Prime Minister in the 1980s. Simultaneously, Jorma Lillbacka also grew the crimping machine business alongside the sheet metal company.

The growth continued throughout the 1990s with company acquisitions, the opening of new factories, more laser-punch combi machines, the arrival of servo-electric punching technology and a new generation of machines. Whilst the company was evolving at a rapid rate, the entrepreneurial founder set up a transportation and logistics business to ship the machines worldwide. Whatever Jorma Lillbacka required to expand his empire, the serial entrepreneur started his own business rather than rely on an external supply chain. Jorma sold the Finn-Power business in 2002 to EQT and in 2008, the Prima Industrie Group became the proud owners of a world-leading brand that perfectly complemented their laser cutting technology.

After the acquisition, the group re-branded its machinery division as Prima Power in 2011 and it has made huge leaps forward with new energy-efficient technologies. It has also introduced the market-leading Genius series of machines and made the 2018 move to the new purpose-built Seinäjoki factory. As for Lillbacka, now in his late 70’s, he followed his childhood dream of building an amusement park in Finland.

Factory Tour

The 2018 move to the new 20,000m2 Seinäjoki factory enabled Prima Power to accommodate its spares, assembly, testing, warehousing, shipping, 24/7 worldwide support department and showroom – all under one roof. The rationale of the new facility was to create a new factory layout that would enable Prima Power to streamline assembly and subsequently increase output by 40%. It now ships more than five machines (with automation) every week – each one is bespoke to the customer.

Touring the facility with Prima Power Manager for Sales Support, Mr. Antti Rintaniemi, he confirmed that more than 250 staff work at the site with another 150 employees working remotely on service, installation, R&D and additional support functions. The facility focuses on assembly and testing with the majority of production conducted by a local supply chain. Highlighting why the company chooses to only assemble on-site, Antti says: “You have to look back at our history. In the 1990s, we still did everything ourselves from design and manufacturing to assembly and commissioning, but over more recent years we decided that as a business you need to focus on one area. We decided to focus on the design and assembly. We used to retain elements such as welding, but the output wasn’t high enough to automate the process and deliver optimal efficiency. So, we decided it was more efficient to outsource these services to specialist manufacturers.”

“We have very long-standing relationships with our subcontractors. For example, as we manufactured everything internally in the 90s, we gradually sold divisions of the business and these companies still serve us today. Now, it is only manufacturers of specialist products like linear guideways that are supplied to us from outside Finland,” says Antti. For owners of legacy machines that date back to the 1990s and beyond, it is certainly reassuring to know that OEM parts are still available with service and support in the UK.

Looking at the multitude of assembly lines on the shop floor, Prima Power manufactures more than 5 machine types at the facility with a complete array of product variants that can all be connected to a labyrinth of automation solutions. Alluding to this, Antti tells MTD Magazine: “We have basic machines but there is always some sort of punching machine variant. For example, there is a combination machine that combines laser cutting and punching or shearing and punching. Some customers only want the punching machine. So, there are six models and each of them has two or three size variations. Then we have the automation to include. Some of the automation systems are common, so a variety of machines could use the same system, but there are upwards of 10 different automation modules. We then have different sizes for each of these modules, so the number of models and variants can be very diverse. Even with our Night Train storage system, we have two different models, one accommodates 1.5 by 3m sheet while the other holds sheet up to 2 by 4m.”

“We manufacture the punching, combination machines and automation, but we are also building automation systems for 2D lasers and panel bending systems as well for our parent company in Italy. We are always trying to sell bigger installations to our customers, so we are integrating complete systems that can include panel benders, lasers and punching machines that are incorporated into a single cell that is harmoniously automated around the needs of the customer.”

“All the machines we build are already sold; we produce nothing for stock. This is primarily because there are so many options for our machines. For example, the tooling turrets have a range of different tool sizes and stations, so even if we do have a customer – the machine in stock would never be precisely what they need. This enables us to avoid post-production modifications. Despite building bespoke machines to order, the lead time can be as little as eight weeks – this is because the annual forecast has been established and submitted to the supply chain in advance. For large systems with automation, we have to book a timeslot for R&D work and these tailored solutions can have a lead time upward of 8 months. However, we also test all of our machines before shipping, this eliminates issues during installation and commissioning. Our suppliers keep a stock level of components, and this ensures a rapid supply of parts to our assembly lines on a Just In Time basis whilst ensuring we do not need to keep stock items.”

Looking to the future, Antti says: “There are plans for expansion in the future, but nothing has yet been decided. The factory floor works two shifts, and this covers production for 18 hours a day from 6am to 12am. Concerning technology, we are continually advancing the business and our product lines with new developments that are exceeding the customers’ expectations with an ability to outperform technology from our rivals.”

This technology is on show in the 7000m2 technology centre that is the centrepiece of the state-of-the-art Seinäjoki facility. Here, Prima Power demonstrates its complete armoury of solutions from the Laser Genius+1530 with the PSR (Picking and Stacking Robot) to the new EBe 2720 servo-electric driven panel bender that demonstrates the company’s latest API technology. In fact, the EBe 2720 panel bender forms part of a complete PSBB (Punch, Shear, Buffer and Bend) automation solution in the Technology Centre. At one end, this colossus automation system that stretches some 40m and has the Combi Genius CG1530 laser and punching machine is fed by the Night Train Genius automation system. The Night Train in the Technology Centre has more than 60 storage cassettes – each with a capacity to hold 3 tons of sheet steel.

Completely configurable to the demands of the end user, the impressive Night Train has the CG1530 at one end and at the other, a line that feeds the Shear Brilliance 1530 punching and shearing machine. Sheets fed to the Shear Brilliance 1530 are then transferred to a buffering station where sheets and parts can be removed, added or flipped over for transfer to the final station, the EBe 2720 panel bender. During our visit, the exceptional level of flexibility and automation was demonstrated with a complete kit of parts being manufactured for an office furniture assembly – but we’ll take a closer look at this technology in the next edition of MTD Magazine in January.

Brother provides unattended production

A lack of skilled engineers and a desire to work a 4-day single shift week played a part in prompting JWA CNC to purchase a Brother 30-taper M200X3 mill/turn centre with an integrated BV7 component stocker and robotic handling to automate its production. Installed in early March 2023 at one of the subcontractor’s two factory units in Leicester, the turnkey cell was supplied by the Japanese manufacturer’s sole sales and service agent for the UK and Ireland, Whitehouse Machine Tools.

JWA CNC produces a lot of prismatically machined components in mainly non-ferrous materials to single-figure micron tolerances. They are required in relatively limited quantities from 3 to 100-off, sometimes fewer if they are for R&D projects, so the company needs automated production systems that are fast to change over to a new batch run.

Operations Director at JWA CNC, Pete Wood said: “Automation of lathes is easy using bar magazines and we have numerous turning cells on our shop floor. However, autonomous production of milled components is more problematic because of the high diversity of shapes and small batch quantities.

“The typical selling price of prismatic parts going through our factory does not justify the purchase of a machining centre with a pallet storage and retrieval system, as they tend to be expensive and are also space-hungry. So robotic handling into and out of the machining area was a necessity.”

An early move towards this type of automation was made three years ago when the company decided to add a 6-axis cobot to a 4-axis BT40 machining centre on the shop floor. Operating with a single tray of parts, it works well unattended but has a couple of drawbacks. First, it is relatively slow to exchange a finished machined component for a new billet, taking around 3.5 minutes; and second, the automation takes up a lot of space.

In contrast, the Brother system avoids both by executing component exchange in well under half a minute and by compressing the machining centre complete with its automation into a 3.5m by 4.1m footprint.

The integral robot has four CNC axes, three rotational and one linear into and out of the machine via an automatic door. It carries twin grippers with the end effectors opposed to each other at 180 degrees. They load and unload parts into and out of a pneumatically actuated fixture on the rotary table mounted on a trunnion that swivels from +120 to -30 degrees.

Three notable aspects of the Brother M200X3 are that it is the third BT30 machining centre in the factory but the first with a face-and-taper spindle; the second 5-axis model on-site; and the only milling centre with a torque table capable of turning components in the same set-up. Several parts produced by JWA CNC require pre-turning before prismatic machining, so there will be a saving by performing both operations on the Brother, especially if the subsequent 5-axis milling and drilling allows parts to exit the machine in fewer set-ups, or perhaps even one.

An often overlooked additional benefit of a 30-taper machine over a 40-taper model is that, due to the former’s high productivity, a typical part is produced faster and therefore with less energy. Combined with numerous efficiency measures within the machine, such as reduced air consumption, hybrid drive motors with power regeneration, high-efficiency pumps and auto-off functions, it results in less power being consumed per part manufactured. Brother claims an overall reduction in energy consumption of around 80% compared with using a 40-taper machine to produce any given component.

Miyano is a cunning fox for Vixen

Located at the foot of Snowdon, Llanberis-based Vixen CNC Ltd is a specialist manufacturer of PPE equipment and height safety systems. With a plant list that includes a range of sliding head turning centres, turning centres from Mazak and Nakamura and Mazak machining centres, one of the latest acquisitions is the new Miyano ANX42SYY from Citizen.

Founded in 1999, the ISO: 9001 manufacturer that sits in the beautiful Snowdonia National Park is a typical subcontract manufacturer with customers in the automotive, marine, military, medical, motorsport, and offshore power generation sectors – but what sets this company apart is its investment in high-end machine tools. Commenting on its latest investment, Ricky Jones from Vixen CNC says: “We wanted to bridge the gap between our investment in fixed head and sliding head machines – that is why we have just bought a Citizen Miyano ANX42SYY.”

“On a 316 stainless component that we are making out of 1.5-inch diameter bar for the oil and gas industry, the new technology on the Miyano ANX42SYY has made the running of the part a lot better. This job used to get produced on our sliding head machines, but now that it is done on the Miyano ANX42SYY, we are getting improved unmanned running, the tool life is significantly improved – and the job just runs a lot better,” says Ricky.

“Another reason why we invested in this Miyano ANX42SYY is because of the FANUC CNC control system. All of our sliding head machines are FANUC controlled, which has made the programming a lot easier to copy over from the sliding head machines to the new Miyano machine. The intuitive control has features such as a display for the power output and also the regenerated power that it is accumulating. This sits well with our business and how we have also just invested in solar panels on our roof. Since March, we have reclaimed 45MW,” says Ricky.

Looking at another challenging component where the Miyano ANX42SYY has made an improvement, Ricky continues: “On this job, I had an issue with swarf building up on one of my drills. When I first set the job up, I had to stop it every 10 parts. Now, I can run the LFV swarf control system and the drill will process 400 parts without removing the swarf once. I have had full backing from the Managing Director on this machine. Only the other day, he asked me not to run lights out because he was nervous that something would go wrong. I told him that the job would be fine and we could run lights out – the job worked perfectly overnight and unmanned. This machine is the first large project that I have been given and the support that I have received from Citizen has been excellent. Obviously, living in North Wales which is quite far from most manufacturing industries in the UK – Citizen have always been at the end of the phone. This is particularly the case with Stewart, the applications engineer who has always been helpful every time I have had an issue.”

“One example of a challenge the Stewart to help me with was an LFV issue. The LFV wasn’t working because one feature was not turned on, I phoned Stewart late that evening and by 10am, the issue was resolved and the machine was running. The improved cycle times and the unmanned running has been the thing that has impressed me the most with the Miyano. This makes my job a lot easier as I can get parts off the machine and out of the door sooner than we initially planned. We can then get the next job onto the machine. At the end of the day, ‘time is money’ and if we can get things off the machines quicker, that benefits our business,” concludes Ricky.

🎧 Factory 33 supported by Hurco from day one

Located in Carterten, Factory 33 is a family business headed up by Martin Krzywina, and Karina Ringer-Krzywina. With more than 10 years of experience in manufacturing precision components for the F1, aerospace, nuclear, medical and cryogenic sectors; this was immediately the target area for the engineers when they started the company in 2015. The journey started with two machines from Hurco.

Managing Director Marcin Krzywina says: “We make everything from aerospace to motocross parts and we also supply most of the F1 and Formula E Teams. These are typically high-precision critical components. The first two machines we bought were a Hurco TM8i lathe and a Hurco VMX30i machining centre. At the time of starting the business, the building was under construction, but we laid out the factory as a lean manufacturing facility.”

“We approached Hurco about a year before we decided to open the doors for business. So, we approached several machine tool suppliers but Hurco were the ones that really did take us seriously. They were on board with our concept and plans and they wanted to support us as a new business – other companies did not.”

Looking at the Hurco VMX30i machining centre, which was the first machine to land at Factory 33, Marcin says: “It’s a great piece of kit with a huge stroke in the X-axis and we have added a 4th axis unit to this machine. We have through spindle coolant and we can do a lot of great parts on this machine – it has all the bells and whistles like full probing, it has the full package. What you see with Hurco is what you get. The machine you see in the showroom will be delivered with the same specifications.”

Another machine the company specified was the full simultaneous 5-axis Hurco VMX30UDi, alluding to this, Marcin continues: “We needed this machine because our customer components were getting more complex and the 5-axis gives us the edge of making these parts quicker, more accurately and with a better finish. This is because the machine is a direct drive spindle with 15,000 rpm. Some machines are belt-driven, but this one in particular is a direct-drive machine that creates less vibration. With Hurco, the parts and the finishes are impeccable.”

The cleanliness of Factory 33 is incredible. Part of this is down to the Lean Manufacturing philosophy where every tool, collet and accessory has a storage place. However, it is also down to good housekeeping. As Marcin adds: “We have to keep our facility clean because when we are being audited by medical companies, we have to be on our best behaviour – it’s just what the industry demands. We are trying to operate on the level of Formula One. An extremely clean machine shop is our goal.”

Asking Marcin for his opinion on what makes a good machine tool, he tells MTD: “It’s all about the axes. Everything in a 5-axis machine shop is about the axes. On this 5-axis machine, we have a 250mm diameter capacity and we can get to the centre of the table rotation with only 125mm of the tool protruding from the spindle. This is excellent and ensures we will have no collisions whatsoever. When I’m looking for a machine, I am looking for the complete package – I want as much included in the package as possible. When you look at some brands, you could be missing an air gun, the coolant wash down or another feature – these are typically extras but with Hurco they come as standard.”

Alluding to what makes life easier, Marcin says: “When we are looking for machines, we want to see the retailer selling the complete package. It makes life a lot easier when everything is included – as much as it can be.” Looking at software, the Managing Director continues: “The software side of the machine also has to be straightforward. With the Hurco brand, everything is straightforward – we love the WinMAX control and the graphics. You can manipulate the graphics in any way that you want. The graphics don’t only show the solids, but also the tool paths. If you have any gouges on a component, you can go back to the control. If it’s simulated incorrectly on the control, that means you need to go back to your CAD/CAM system and fix it.”

🎧 Embracing a ‘one-stop-shop’ supplier

Full 5-axis capability plays a pivotal role in Maycast-Nokes’ production processes. Situated in Halstead, Essex, the company invested in their initial 5-axis machine over two decades ago—a HAAS VF-2 vertical machining centre equipped with a trunnion unit. Sales Director at Maycast-Nokes, Mr Dave Blower explains: “This marked our first investment with HAAS. Although initially intended for a specific project, it had a tremendous impact on our entire machine shop.”

Adding to this, Dave says: “At the time, we did not possess any other 5-axis machines on-site. However, we found the transition to be seamless, and the HAAS control system proved to be highly intuitive. Opting for a 15,000rpm spindle reduced our cycle times by 50% when combined with the 5-axis.”

Since the 1950s, Maycast-Nokes has functioned as a foundry and progressively evolved into a comprehensive engineering business through gradual technological investments. Financial Director Derek Redgwell states: “Our workforce now comprises 120 individuals, including ten apprentices working across various departments.”

All ten milling machines in Maycast-Nokes’ facility are HAAS CNCs, with seven of them being UMC Universal Machining Centres. Dave proudly shares: “We purchased one of the first UMCs in the UK, and it perfectly suits the majority of our component requirements. We were so impressed that we continued to invest in them.” The UMC-750 models utilised by Maycast-Nokes boast a 15,000rpm spindle, a 40+1 side mount tool change capability and simultaneous 5-axis machining.

Dave further adds: “With each new machine, we have observed ongoing upgrades and refinements from HAAS. They consistently strive to enhance their products. For example, the door size has been redesigned to allow more natural light into the workspace, the control position has been optimised for improved user-friendliness, and the addition of a touchscreen has proven to be highly convenient.”

HAAS 5-axis machining has been enhanced with the introduction of TCPC (Tool Centre Point Control) and DWO (Dynamic Work Offsets). TCPC allows the machine to precisely control the position of the tool’s centre point, ensuring accurate machining regardless of the part orientation. It eliminates the need for manually calculating offsets, greatly simplifying programming.

DWO dynamically adjusts work offsets in real time during the machining process, compensating for any machine or fixture deflection. This capability ensures consistent part quality and reduces the need for manual adjustments or recalibration. With TCPC and DWO, HAAS 5-axis machining has become easier than ever, allowing operators to achieve intricate geometries and complex machining tasks with confidence and precision.

“We’ve just taken delivery of a UMC-500 and UMC-1000. The footprint of the UMCs is the reason we can fit so many into the workshop. With the speed of the machines, we can be more competitive in our quoting, which brings in more work, enabling us to invest again. It’s a circle which is very successful for us.”

Given the precise nature of the castings, primarily targeted for the aerospace and defence sectors, maintaining tight tolerances is paramount. Dave explains: “Each casting has full dimensional reports and needs to pass inspection before it leaves us, so repeatability is essential. The HAAS machines are great for consistency and accuracy.”

Over the years, Maycast-Nokes has nurtured a strong relationship with their HAAS Sales Manager. Dave comments: “Don Cole is always willing to visit us whenever we need anything. He has assured us of unwavering engineering support, and that is precisely what we get. We chose HAAS for their competitive pricing, but it is their exceptional service that has fostered our loyalty.”

🎧 In safe hands with CMZ

Founded before the First World War, Tybro Bros (Sutton in Ashfield) Ltd has evolved over the last century. Formed in 1914, it has progressed from a business with motor and electrical engineers to precision engineering. The company has a reputation for its excellent standards – something underpinned by its investment in machine tools from CMZ.

A family business spanning more than four generations, the Kirkby-in-Ashfield company is a typical subcontractor that serves all industry sectors. With a customer base that boasts brands like Thorntons, OTIS, the UK Atomic Energy Authority and Transport for London, the company was instrumental in the redesign of the stop switches on the London Underground and the contract remains in place more than 40 years later. In fact, it was the father of the current Managing Director, Mandy Tyler who designed and developed the London Underground stop buttons.

Describing the business, Mandy Tyler, Managing Director of Tybro Bros Ltd says: “We specialise in machining, fabrication and assembly; manufacturing components for critical industries – we push the boundaries of those industries. We are producing components that have never actually been made before from drawings that have never been designed before, and that is why there is so much skill involved in our business. We also need the machinery to support our skilled engineers.”

The company purchased its first CMZ machine in 2011 and the relationship has continued from there, as Mandy adds: “The first machine was a single spindle lathe and as the years have progressed, we have gone from single spindles to sub-spindles and Y-axis machinery. This progression has been based on the type of components that we manufacture.”

Adding to this, Mandy says: “We deliver to key industries that demand critical parts, so we absolutely need the machinery to be robust and reliable for us to deliver to our customers on time. I have great confidence in the CMZ machines as they hold tolerances very well – and this is critical, as the drawings we work to have very tight tolerances. We machine a variety of materials from plastic through to mild steel and superalloys, and when it comes to materials like Inconel, it is very handy to have the extra power of the CMZ TA Series.”

Mandy continues: “Since investing in our first CMZ machine in 2011, we found that the brand has just worked for us, so we have invested time and time again. Our most recent purchase was a CMZ TD35 turning centre that was bought purely to keep up with customer demand, as we are busier now than we have been in the last  six years.”

The TD35 is a CNC lathe that allows multiple configuration options that can be adapted to the demands and particularities of each production process. All models have a turret with a built-in motor offering 12,000rpm driven tools and integrated spindles. Laser compensation is also a standard feature on all TD Series machines with automation of both short and long batches possible via the GL20 and GL100 Gantry robots that will lift to 100kg.

“One of the unique features of the CMZ machine is the turret design. It has a 12,000rpm driven motor, which has 13kW of power. So, when you cut materials like nimonics, the Y-axis is like a machining centre with incredible power. Tybro now has four machines from CMZ and this is due to the accuracy and performance over a prolonged period. This is important to Tybro, as the company specialises in machining difficult materials for critical industries,” says a member of the CMZ team.

As Mandy concludes: “As the demands have grown in our turning department, and since we bought our first CMZ machine, our machinists have found CMZ machines to be fantastic to use and very intuitive. For this reason, we have invested time and again in CMZ machines, so that we can have standardisation in our factory.”

🎧 Cutting costs with a fluid solution

By Rhys Williams

Founded back in 2011, Cwm Engineering is a subcontract manufacturing business that has grown at an exponential rate since its inception. The relentless growth trajectory for this West Wales manufacturer is a credit to its approach to continuous improvement and delivering impeccable quality for customers. So, when the Crosshands company was having challenges with its cutting fluid, it turned to Oemeta for a solution.

Like any subcontractor that has a diverse range of manual and CNC machine tools employed to process a wide variety of materials from plastics and aluminium to steel and heat-resistant alloys, the challenge is finding the optimal ‘factory-wide’ cutting fluid solution. As the company has expanded and acquired more advanced machine tools, machine uptime and productivity is critical – as are health and safety and the well-being of staff. Unfortunately, previous cutting fluids and the respective suppliers have been detrimental to the ISO: 9001 certified company and its goals.

Discussing past challenges, Company Founder and Managing Director Malcolm Walters says: “We were using fluid from a world-leading brand and we found the performance was diminishing with our acquisition of higher-end machine tools. The cutting fluid was delivering poor sump life, bad odours and it was creating skin irritations for staff. We then moved to another high-end brand that had no nasty chemicals. This eradicated workshop odours and skin irritation for our staff. Whilst the new fluid initially had a better sump life than its predecessor, performance was inconsistent from one machine to the next. Furthermore, customer support was poor and we were undertaking all of the fluid testing and topping up internally. Ultimately the fluid cost was also increasing drastically – we needed to find another solution.”

A Timely Knock on The Door

Serendipity played its role when Ryan Aviles, the regional sales engineer for Oemeta made a chance call upon the West Wales business. Inviting the Oemeta representative for a conversation has paid dividends for Cwm Engineering. Initial consultation regarding the machine tools, type of machining, material types and the issues with existing products provided Oemeta with a scenario of what was required. The cutting fluid company narrowed the solution down to two products and it was the Oemeta NOVAMET 760 water-miscible metalworking fluid that was identified as the optimal choice for Cwm Engineering.

With more than 12 machine tools on the shop floor, Cwm Engineering and Oemeta initially agreed to trial the fluid in one machine, a Mazak VTC-530C vertical machining centre. The results were immediate. The first two fluid brands offered a sump life of 2 to 4 months, a huge variation in sump life that Cwm Engineering or the fluid suppliers couldn’t diagnose. The Oemeta NOVAMET 760 has now been in the Mazak VTC-530C for over 12 months with no issues, increasing the fluid life by more than 70%.

With the results of the first machine being so evident, Cwm Engineering agreed on a staggered approach to incrementally phase out the previous fluid and install Oemeta’s NOVAMET 760 in all its machine tools.

Service With a Smile

Commenting upon the implementation process, Cwm Engineering’s Systems and Operations Manager Andrew Ritchie says: “We have a company to conduct annual health and safety audits and we pay due diligence to all H&S aspects. With our previous fluid, the well-known supplier provided a poor level of service. I would spend up to 3 hours each week conducting pH and calibration tests on all machine sumps. We had to buy calibration kits, incubation tubes and an incubator and during testing, we would have to leave the fluid in incubation tubes for 48 hours before testing the bacteria levels. We had to buy a £350 bacteria kit and pay a £30 fortnightly subscription for test tubes and dip slides. The cost and effort expended was excessive and added to this, there would be another couple of hours spent topping up the machines.”

“Despite dedicating significant time and resources to our coolant management, the previous fluid performance would incrementally deteriorate and then ‘fall off a cliff’ overnight. We even tried ozone generators to oxidise the coolant and kill bacteria. Unfortunately, there was no explanation for the fluid behaviour and the support was very poor. In contrast, Ryan and the Oemeta team have been fantastic.”

Whilst Oemeta emptied and cleaned the sump on the first Mazak machine, rather than empty the sump of each subsequent machine, the technical experts at Oemeta identified if NOVAMET 760 would be compatible with the existing fluid. Once this was clarified, NOVAMET 760 was then used to top-up existing fluid levels in the rest of the machine shop to minimise disposal costs for Cwm Engineering. Oemeta also implemented its fluid management protocols at Cwm Engineering. This has included fluid management instructions on each machine tool along with a service record card. Most importantly, the Oemeta engineers visit the Carmarthenshire company every fortnight to undertake fluid management activities that include testing the pH level, bacteria, fungus and sump levels and concentration.

The Savings

Introducing Oemeta’s NOVAMET 760 has been an incremental process over the last 12 months – and it is only now the true level of savings can be fully quantified. From a cost perspective, the previous cutting fluid was costing upwards of £2600 a barrel and the 12-employee business was buying up to 6 barrels a year with a cost of more than £15,000 per annum. The Oemeta fluid costs almost 50% less than its predecessor, making an immediate saving in the region of £7000. At least that would be the case if they were used in equal measure. With the remarkable fluid life improvement, Cwm Engineering is only purchasing 2 to 3 barrels a year – a fluid life that will inevitably improve further when the remainder of fluid from the previous vendor evaporates from the machines. There is potential for the subcontract manufacturer to reduce fluid purchasing costs by more than 80%.

What goes in must come out

Not only are Cwm Engineering making huge savings on coolant costs and the associated cost of weekly testing and the labour hours involved, but they are also making savings on fluid disposal. Cwm Engineering has two 1000-litre IBCs that are filled with waste coolant and disposed of two to three times a year at a cost of up to £2400. Not only is there a significant financial cost, but also an environmental impact. With fluid life increasing by more than 70%, inevitably, disposal costs will also fall by 70% – this is estimated to save an additional £1600 in disposal costs for the company. Furthermore, with the previous fluid almost turning rancid overnight, machines would have to be emptied and cleaned for £600 – a frequent cost that has also been eliminated.

Benefits beyond the wallet

The cost reduction of implementing Oemeta’s NOVAMET 760 has been staggering for the family business, but the benefits are far further reaching. As Andrew Ritchie adds: “We have taps near each machine and we have a barrel of NOVAMET 760 with a mixer on a trolley that can be wheeled to each machine. Once the barrel and mixer are connected to the tap, we can easily top up the fluid in any of our machines. Simply doing this has saved us hours every week and with Oemeta managing the condition of our fluid every fortnight, we are saving significant man hours on fluid testing too. There is also no need to have machines down for sump cleaning any longer, which can be a huge inconvenience to our business.”

The performance of the fluid is also improving quality and productivity at Cwm Engineering, as Malcolm Walters concludes: “Oemeta provides a long and predictable sump life which is critical to our machine shop and keeping our spindles turning. The soluble Oemeta cutting fluid has significantly reduced fluid consumption, extended tool life, reduced machine downtime and massively reduced waste disposal costs. Moreover, our surface finishes have improved and staining on particular types of aluminium is now a thing of the past. We have witnessed situations where parts that need to be aesthetically pleasing have been stained by coolant and this has resulted in scrap – this is now a thing of the past. We are delighted we made the change to Oemeta, we cannot speak highly enough of their products and service.”

🎧 The right tool for the right CNC

The history of computer numerically controlled (CNC) machines dates back seven decades. During the 1950s, CNC technology was difficult to introduce due to manufacturers’ scepticism. Today, it is hard to imagine the world of manufacturing without CNC machines. In material removal processes, a CNC machine has become the central link that determines the functional capabilities of a manufacturer.

CNC machining centres are complex machines that continue to evolve and improve. The advancement of CNC technology is based on the progress in various fields such as the main spindle and its bearing units, machining slideways, high-velocity drives, computer engineering, hydraulics, electric motors, robotics, sensors and much more. When compared to a conventional machine with mechanical parts, the share of modern digital CNC machines is significantly higher.

CNC technology will continue to be the backbone of machining methods in the near and far future. The development of CNC machines is intended to increase the versatility, productivity, stability, reliability and accuracy of a given machine. These targets are ongoing milestones that assure contemporary machining results. The leap forward relates to machining centres that combine subtractive and additive technologies that are both CNC machined and 3D printed. At the same time, a complete rethink of CNC advancements has been brought about by Industry 4.0 and the concepts of smart manufacturing. In a smart metalworking factory, there is a continuous information exchange between the real world of CNC machines and the virtual world. This world functions according to the features of the machined parts and their respective theoretical characteristics. Smartly balancing on the boundaries of these worlds and analysing the real-time information is the ability to make decisions and corrections that are made by computer-controlled units.

One element that is much smaller, substantially cheaper and considerably less complicated when compared to a CNC machine tool, is a cutting tool. The tool is the link that directly removes material from a workpiece and closes the process loop of ‘machine and workpiece’. Due to objective reasons, the cutting tool element is subjected to less fundamental changes and the cutting tool is frequently identified to be the weakest link in the processes. Something that also limits system capabilities. Therefore, appropriate upgrading of cutting tools should be considered as an integral part of the progress of CNC technology.

A conventional approach to making cutting tools relates to designing innovative cutting geometries, using advanced cutting materials and applying leading production technologies that are intended to improve tool life, ensure greater material removal rate (MRR), provide higher accuracy, and increase reliability. Nevertheless, Industry 4.0 trends in the development of CNC technology are placing ever greater priority on the digital component of the cutting tool.

Information has constantly accompanied cutting tools even before Industry 4.0. Catalogue data, tool drawings and recommendations regarding applications were provided in printed formats and later in electronic formats and these continue to be essential for the typical metalworking machine shop.

Computerisation has affected customer support by providing expanded capabilities in the form of data. Various software applications have enabled the selection of optimal tools and the ability to estimate tool life under specific machining conditions. The combination of ISCAR’s NEOITA and its Power Consumption applications enables a quick calculation of cutting forces, bending load and power consumption. It also enables the user to find suitable cutting material grade, the right tool for a specific application and provide an analysis of competitors’ products alongside other useful functions. Customers can easily access data and related information through computers and mobile devices, but now, advancements in network communications have introduced the world of metal cutting to the virtual electronic world.

Digital twin technologies complement manufacturing processes. Machining modelling, collision checking and process optimising to find the best cutting strategies are only some examples. In a smart factory, the digital twin is the most significant brick of the foundation. Understandably, only a tool having its digital twin is acceptable for the smart factory’s toolroom.

The progress of CNC technology leads to new demands for cutting tools. A tool manufacturer is expected to be a provider of a product that ideally combines a cutting tool as a material object, its real-time digital twin and an appropriate software environment. This allows the seamless incorporation of the tool data in the CAD/CAM and virtual manufacturing environment, directly transmitted by Internet of Things (IoT) networks – tool packages and virtual assemblies.

To make tool representation clear for various computer systems, the ISO: 13399 standard was developed and ensure the platform’s independence. This standardisation is necessary for other digital components of the tool package to unify data related to tool life, calculated loads, machining conditions and lots more.

ISCAR’s digital tool component, which is based on the ISO: 13399 standard, includes the following characteristics:

A rapid pace of industrial digitising takes CNC technologies to new heights. This gives a boost to appropriate changes in the product range of a tool manufacturer and demands strong links between a cutting tool and its virtual digital component.

The view from Quickgrind

In 2023, the UK’s manufacturing sector has navigated global challenges and evolving economic factors. Quickgrind, one of the UK’s leading solid carbide tooling manufacturers, has adeptly steered through these challenges with innovation and resilience. MTD magazine sat down with Quickgrind’s leadership team to gain insights into the state of the country’s solid carbide tooling and manufacturing markets, while also discussing broader economic factors affecting the industry.

MTD magazine asked Quickgrind Managing Director, Mr Ross Howell for his assessment of the UK market in 2023.

Ross Howell said: “Through 2023, the UK’s solid carbide tooling industry has continued to demonstrate resilience and growth. With a strong focus on precision engineering and manufacturing, the sector has evolved to meet the demands of cutting-edge industries such as aerospace, automotive and medical. Advances in technology such as CNC machining and 3D printing, have enhanced production processes, delivering innovative, high-quality durable tools.”

“Sustainability is increasingly important and this is leading to the rise of eco-friendly materials and recycling initiatives. In terms of R&D, the UK remains a global hub for research and development in carbide tooling, fostering innovation and international collaboration. Yes, there continue to be challenging factors such as Brexit, the war in Ukraine, volatile interest rates and supply chain disruptions, but I would say that the solid carbide tooling industry in the UK – and UK manufacturing in general, is thriving and at the forefront of global competitiveness. This has certainly been our experience here at Quickgrind where we continue to innovate, invest and expand.” 

MTD magazine asked Brian Pearce, the Sales Director for UK & Ireland at Quickgrind to tell us more about the challenges faced by UK manufacturers of solid carbide tooling?

Brian said: “Like every serious business, we continue to face challenges in domestic and international sales, including factors such as global competition, access to some markets, distribution logistics, skills shortages and price pressures. Forward-looking companies like Quickgrind are responding positively to these challenges with improved quality assurance procedures, technological advancements, investment in people and customer relationships and also tool customisation.”

Adding to this, Ross says: “As Brian says, we are finding that our agility in terms of tooling customisation is an attractive proposition to our client partners. Our ‘Infinite Possibilities’ customisation programme ensures we can meet the specific tooling needs of our clients. This is attractive to them as they look to respond to their own manufacturing challenges that are machining-specific and often involve difficult materials in very specialised sectors such as aerospace, automotive and medical. Furthermore, there is the demand for high tolerance levels and repeatability, and of course short lead times. It’s not unusual for our clients to see annual machining savings of 30, 40 or even 50% by adopting the right tool for the right job, which more than outweighs their initial investment.

MTD magazine: Is there anything else you have done to respond to market challenges this year?

Brian responds: “Although we are perhaps best known for our customised tooling, we have also introduced a 400-strong standard tooling range. This means we are now able to offer the same, high-quality tooling that people have come to expect on a next-day basis. We’ve developed the range using our extensive experience and knowledge of the kinds of tools that are needed most often. These tools are of the same quality, precision and repeatability as our bespoke tooling.

Ross says: “Yes, the breadth of our product range offers a sense of security for our customers. They can rely on us to supply the critical tooling they need when they need it.

Making hard turning easy

The machining of hardened materials beyond 55HRc is becoming increasingly commonplace in the industry, so it stands to reason that manufacturers need the right cutting tools to handle these tough machining jobs. Ceratizit recently launched its new HardCut selection of indexable inserts to ensure that these demands can easily be met, so MTD magazine has taken a tutorial from Ceratizit on hard turning to educate our readers.

Hard turning, as an alternative to grinding, comes with many advantages. Whilst eliminating grinding sludge and the need to use cooling lubricant, Ceratizit’s HardCut inserts increase productivity by shortening set-up and machine production times. The increased process flexibility means that internal and external machining on the same machine is possible, whilst also increasing the ease at which complex geometries can be produced. So, let’s take a closer look at hard turning…

Extremely hard cutting materials above 55HRc enable manufacturers to machine hardened cast iron materials with geometrically defined cutting edges. At the top end of the cutting material hardness scale are polycrystalline diamonds (PCD) and cubic boron nitride (CBN), which is usually the first choice for hard machining.

Cutting material – hardness comparison

PCBN is one of the hardest materials in the world. In addition to many other exceptional properties, it is this hardness which makes the material ideal for machining hard, abrasive components. PCBN has greater chemical and thermal stability than diamond, which reacts with iron and has a maximum temperature limit of around 700°C. PCBN is resistant up to temperatures exceeding 1000°C.  and is therefore ideal for the high machining temperatures generated when hard turning.

The materials being machined can have a hardness of up to 67HRc. Case-hardened steels are subject to soft pre-machining (unhardened) using carbide indexable inserts. After hardening (minimum hardness of steel 55HRc) areas showing hardening distortions and also the running surfaces must be reworked. When finish machining with PCBN, surface finishes up to Ra0.2 and close tolerances can be achieved, often eliminating the need for grinding. By eliminating the grinding process with hard turning, customers can reduce cycle times, reduce the number of operations required and even conduct several machining operations with a single tool.

The Principles of Hard Turning

The softening of the chip thanks to high cutting speeds is the basis of hard machining. Shear chips can be created on hardened steel as a result of the cutting energy introduced (high temperatures). Carbide indexable inserts have a higher flexural strength than PCBN and are therefore more suitable for soft machining. From a hardness of 50HRc, the temperatures generated during machining are so high that the wear of the carbide indexable insert is uneconomically high. The reason for this is the insufficiently elevated-temperature hardness of the carbide. In contrast, PCBN has a higher hardness than carbide and can still be used cost-effectively at high temperatures.

Segmented chip with chip thickness

If machining with a reduced width of cut of hm>0.02mm, the material (chip) is cut out and upwards, and the individual chip segments remain stuck to one another – forming the typical saw tip structure.

Continuous chip with small chip thickness

If machining with a reduced width of cut hm<0.02mm, a continuous chip is created and typical cracks are not created at this width of cut. The chip is evacuated across the tool cutting edge so that there is no swarf breakage and a continuous chip forms.

Application

The basis for hard machining is the softening of the chip as a result of the high cutting speeds. Ideally, the chip is red hot. This can be recognised by the medium-grey tempering colour on the cooled-down back of the chip. Under optimal processing conditions,  the resulting shear chip is brittle and can easily be crumbled between the fingers.

The foundation blocks

To undertake hard turning, conditions have to be optimally suited to the application. Starting with the foundation block – the machine, this should be a robust machine design that is ideally a machine for hard turning, as extensive stress can lead to unstable processes on unstable machines. A turning centre with backlash free guides with a spindle run-out of less than 0.7μm with axis repeatability of less than 0.8μm is preferable. The machine should be well maintained and it is preferable to select a machine with hydrostatic bearings. Ignoring these factors can cause the indexable insert to break uncontrollably, hindering the dimensional accuracy of the workpiece.

A steady rest and tailstock should be used if the required surface quality cannot be achieved. In fact, they are absolutely necessary for long or thin-walled workpieces. Concerning the tooling setup, operators should avoid unnecessary overhangs and clamp the tool as short as possible. Equally important is the workpiece clamping configuration. Operators should observe a length-to-diameter ratio of approximately 2:1 to minimise vibration.

Material effect on hard machining

When machining hardened steel (hard machining), the process involves self-induced hot machining. Here, a defined high temperature of 550°to 750°C is needed in the shear zone. This required temperature is obtained by converting the existing energy into heat. This energy is available in the form of cutting speed (vc), feed (f), depth of cut (a)p and the chamfer geometries F-M-R of the PCBN cutting edges. Cooling is usually not necessary. For self-induced hot machining with Ceratizit’s PCBN grades, the ideal hardness is in the shear zone at 40 to 45HRc.

Cutting edge preparation

The stability of a cutting edge increases as the chamfer angle and chamfer width increase, but at the same time the cutting force increases and subsequently the temperature in the process rises. A larger chamfer distributes the cutting force across a larger area of the cutting edge. This increases the stability of the cutting edge, thereby facilitating higher feeds. If process stability and constant tool life are the highest priority, then we recommend choosing a large chamfer. If the highest priority is to achieve a very good surface quality and optimum dimensional accuracy, then it is advisable to use a small chamfer for the manufacturing process. Vibration, cutting forces and temperature are hereby reduced. Hard turning in most cases is the finishing of the workpiece, the optimum cutting-edge preparation is a deciding factor in reliably producing high-quality components with a long service life.

Advantages of hard turning over grinding

In the past, grinding was a common method used to finish components made of hardened steel. Today, hard turning is considered an efficient and cost-effective alternative. Hard turning can increase productivity massively and offers significant environmental benefits.

The benefits:

There are a multitude of additional factors to consider when looking at hard turning. Additional points to consider include the monitoring of wear – and the type of wear on the cutting tool, what insert coatings should be considered, defining when to change an insert, calculating the surface quality and much more.

🎧 Support milling with the right tools and know how

When outsourced manufacturing processes such as milling are brought back in-house due to the uncertainty of supply chains, up-to-date engineering skills and fresh know how are often required. The general trend to increase productivity and improve profitability may be timeless. However, when it comes to current trends, it is easy to lose sight of the big picture. The selection and use of the right tools and tool holders are critical as they determine the quality and efficiency of the end result. So, wouldn’t it make more sense to consult a cutting tool manufacturer?

If the crises of the past few years have made one thing clear, it is how fragile our supply chains are and how quickly they can be disrupted. The result is that business is done by those who can deliver. Manufacturers and production companies are therefore bringing back in-house manufacturing processes that they outsourced overseas years ago for cost reasons. The trend has been evident for some time. However, a problem arises if the knowledge and expertise have also migrated with the processes.

Bringing back manufacturing processes

In general, the successful machining of steel and, in particular, the precise and efficient milling of steel are impacted by a multitude of factors and their complexity can quickly become overwhelming. Tool manufacturers who can think in terms of the application are therefore a necessity – especially when they are also willing to provide advice on complex production processes.

The Swabian medium-sized company of Karl-Heinz Arnold GmbH with its brand name of ARNO Werkzeuge is known for its first-class turning and parting-off tools. It has been a constant player in these processes for many years. What is less well known is that the family-run company also develops innovative milling tools that are manufactured in Germany. “With a high level of vertical integration, our development expertise and global sales structures, we manufacture high-performance milling tools that are deployed worldwide for efficient milling,” says ARNO marketing team leader Christian Kimmich.

Support often incorporates systems such as a tool holder for corner milling and HFC indexable inserts, a multi-functional system for HFC and corner milling, a face milling system and solid carbide cutters. In particular, a new system for face milling has been introduced and it incorporates a recent new development. “One trend among users is towards smaller machining allowances for workpieces that run faster and at higher feed rates,” says Marco Staiger, Application Engineer at ARNO Werkzeuge.

This is precisely why ARNO has developed the new, stable FT face milling system 09, a system that focuses on the application. The FT system is very stable and features a smooth cut and very quiet running. This provides the spindle with maximum protection and is the result of a large flat face on the holders, a positive rake angle despite the negative mounting position and a differential pitch of the flutes.

More teeth and smaller double-sided indexable inserts

The new FT 09 milling system consists of two variants of stable tool holders covering a diameter range of 20 to 125mm and it is equipped with eight flutes and matching smaller indexable inserts. The differential pitch of the tool holders ensures a quiet and low-vibration milling process. Especially with small allowances, ARNO promises a higher chip removal rate due to the higher feed rates.

“Since we managed to achieve a narrower pitch in the tool holder, even though it has a small diameter, we can now place more teeth on the tool,” Staiger explains. This means that up to nine indexable inserts can be fitted, where only six were possible before. Despite the narrower dimensions, users do not have to dispense with cooling.

Staiger adds: “Through the internal channels for cooling media, cooling lubricant or air for dry machining are fed directly to the cutting zone and ensure significantly longer tool life and optimum chip removal.” A particularly convincing feature is the optimal utilisation of the flute with smaller in-feeds up to a maximum of four millimetres. This means users no longer need to discard half-used indexable inserts.

The large pool of applications demonstrate engineering competence

Those who do not want to opt for ‘fast’ or ‘fine’ machining are best advised to use Arno’s FD milling system. The nickel-plated long-life basic holders for corner milling and the HFC indexable inserts with four efficient cutting edges per insert can combine to achieve a high feed rate. These tool holders also have a differential pitch that reduces vibration and results in smooth surfaces. The system ensures a long service life and is easy to handle.

Most users set their machining priorities with indexable inserts in sizes 10 and 15. The smaller insert achieves high surface finish credit to its large wiper geometry. By contrast, the 15mm inserts are ideal for roughing since they are extremely stable. ARNO offers different geometries and grades to flexibly adapt machining to the application in question. This is precisely where ARNO excels. It draws on the experience gained from a huge pool of applications and can advise on the most suitable tooling system for each case. The precision-manufactured positive chip breakers on the indexable inserts ensure a soft cut. Since they are also peripherally ground and polished, the PMA geometry can cut both aluminium and non-ferrous metals.

With solid carbide cutters, ARNO also has tools in its portfolio that achieve optimum production processes with reduced downtimes thanks to fewer tool changes. The solid carbide metal cutters are made of an extremely fine grain carbide grade between 0.1 and 0.5µm. The consistent material properties are impressive and depending on the design, they are TiAIN, TiCN or AlCrN coated.

ARNO’s FE milling system is an alternative to solid carbide metal cutters. Manufacturers can opt for efficient shoulders or high speed during HFC milling. “In both cases, users benefit from high feed rates, extremely smooth running and excellent cutting ability,” promises Staiger. This is due to the highly positive mounting position of the indexable inserts and the spiral shape of the flutes, ensuring smooth material cutting.

It is also an ideal situation if the tool supplier can adapt to the needs of its customers with special product lines. With the Basic Series, ARNO Werkzeuge offers efficient, rock-solid tools with many grades and geometries that are suitable for a wide range of machining tasks. On the other hand, the tools in the ‘Major’ series are used when surfaces need to be outstanding. Every minute counts when it comes to tool life and difficult-to-machine materials or large production runs. The tools can be individually adapted with a selection of coatings or tool holders.

Conclusion: Milling tools benefit from turning experience

With its carefully designed and well-engineered milling tools, ARNO Werkzeuge has no reason to hide its light under a bushel. This is because it also benefits from the turning and parting-off expertise as well as from its application experience. We were impressed by how the milling systems are precisely developed for different applications and yet offer the greatest possible flexibility. With its extensive portfolio, ARNO serves the trends in milling.

Nuttall install large, twin column vmc

Jones Nuttall Precision Engineering has recently specified a Hurco DCX22i twin-column, bridge-type, VMC with a working volume of 2.2m by 1.7m by 750mm and an eight-tonne table load capacity. This makes the new Hurco the largest item of prismatic machining equipment on the shop floor at the Warrington-based company. The machine is well specified with a 40-station tool magazine, 12,000rpm 18kW spindle and rapids of 32m/min in the X and Y-axes and 24m/min in the Z-axis.

This latest addition to the plant list has considerably expanded the size and range of work the firm can take on. Much of it is carried out by a separate division for Network Rail, London Underground, ScotRail and other well-known names in the rail industry. Repair, overhaul and testing of mechanical/electrical components are a speciality, as well as the manufacture of new components and assemblies to OEM standards and specifications.

Additional prestigious customers include Bombardier, Linde Group and many in the pharmaceutical, energy, oil and gas, petrochemical and defence sectors. Overall, more than 60 employees in the Warrington factory supply more than 30,000 different components to over 250 customers every year. The DCX22i brings to 12 the number of machining centres in use at Jones Nuttall, all of them supplied by Hurco, there being eight VM30i models and other VMCs also in operation. Additionally, a third of the lathes on site are Hurcos, both of them barfed. The TM10 has a 10-inch chuck while the 8-inch chuck TMM8 includes live tooling and a C-axis. 

Metals processed include Inconel, titanium alloy, stainless steel, steel, brass, aluminium, copper and even silver. Engineering thermoplastics such as nylon, acetal and PEEK are regularly machined, as well as composites such as Railko, Tufnol, epoxy glass and polyester. Batch sizes range from one-offs to runs over 1,000. Founded in 1971, Jones Nuttall has been dealing with Hurco since 2000, at which time the subcontractor decided to progress from manual tool change mills to machining centres. It opted for Hurco equipment due to the high build quality and spindle power of both the machining centres and lathes. 

The manufacturer’s proprietary Max5 control is also a bonus, especially as so many operators are familiar with using it these days. Cutting cycles are prepared quickly using the drop-down, touch-screen menus, which helps ensure economical production if only a few parts are to be produced.

Geoff Brown, a machine operator at Jones Nuttall commented: “Hurco machines are very easy to program, set up and use. The twin-screen control on the DCX helps, as I can program and edit on one screen while the other screen displays the component and toolpath. Programming of all the Hurco machines is the same, so often one operator can run two or three machines.”

The constantly changing demands of the railway industry require Jones Nuttall to adapt accordingly. That is why in addition to subcontract machining the firm has a fabrication department with spot, MIG and TIG welding capabilities, plus arc welding machines, punching equipment and guillotines. Many of the finishing processes are also completed in-house, including shot blasting, powder-coating, painting and varnishing, as well as heat treatment and a range of plating, polishing and anodising processes.

🎧 A&M ‘Turns and Burns’with Sodi-Tech EDM

A&M EDM Ltd is an engineering solutions company always striving to maximise its service to clients in the aerospace, motorsport, automotive, marine, medical, rail, defence and general subcontract sectors. To achieve this, the West Midlands company has invested in a diverse range of technology that spans from 3, 4 and 5-axis machine tools and laser welding to laser calibration and more. However, the foundations of the company stem back to its 2002 inception where it all started with a Sodick wire EDM machine from Sodi-Tech.

Wind forward more than 20 years and the Smethwick manufacturer has upward of 60 machine tools with 36 of those supplied by Sodi-Tech. This includes a complete selection of Sodick wire and die-sink EDM machines, EDM hole drilling and high-speed machining centres. Like many subcontract manufacturers, A&M EDM machines a variety of materials that include stainless steel, mild steel, aluminium, inconel, titanium and exotics with a variety of production demands from bespoke one-offs and short runs through to longer run batches for its customers – but one thing that has remained a constant from day one is the technology and support from Sodi-Tech.  

A&M EDM Ltd Owner and Managing Director Mark Wingfield says: “My relationship with Sodi-Tech dates way back to the very start. At the moment, we have 36 Sodick machines and this includes a complete variety of machines. A&M EDM specialises in lots of products. We make everything from parts that go into the ocean to parts that go to Mars. The machines have to be reliable because of the accuracy of the work we do. When you spend so much money on machine tools, you want the machines to last. The Sodick machines are very reliable and rarely break down – if you look after the machines, they will look after you. Having used other machines as well as Sodick machines, I always felt that Sodick are the best machines for me. The brand has made this business what it is today. We have taken this business from two people up to 78 people working here. So, I can only speak very highly of the machines, you really are paying for the best kit on the market.”

Adding to this, Lee Finch, Production Director at A&M EDM says: “We offer next day turnaround and if the machines are not running efficiently, or running overnight as we planned them to, we simply cannot offer that service. What I love about the Sodick machines is how user-friendly they are. You can get jobs up and cutting very quickly without having to go into any extensive technical depth with the machine. However, there is the facility for advanced technical operation in the background, but if you just want a quick fix where you can get the machine up and running for a quick turnaround job, the machines are so easy to operate.”

Bal Dulay, Account Manager at Sodi-Tech says: “It’s great to see so many of our machines on the shop floor. In fact, A&M EDM is the largest user of our machines across the UK and Europe. A&M EDM trusts our machines, so they know that the parts they are producing are of the highest quality. This gives A&M EDM the confidence to know that their customers are getting what they need. This is not a customer-supplier relationship, this is a partnership that A&M have with Sodi-Tech. They trust us and know that we will supply a machine that will do the job and support their goals for the future.”

Over the years the company has acquired everything from the AQ537L, AQ750L, AQ750LH and AQ900L through to the AG60L, AG80L, AG100L, AQ35L, AL60G and the most recent ALC600G.

Looking at the latest ALC600G machine that is just been installed, Lee Finch continues: “This machine offers us a new facility where we can ‘turn and burn’ using full 8-axis controlling. When we are looking in the market for new machinery, myself and the other directors at A&M will evaluate what we are looking for and what we are trying to offer to our customers. We also need to identify how our business is going to get the benefit from that purchase. The more advanced technology that Sodi-Tech can offer, then there is more technology that we can offer to offer our customers – and this is how we have arrived at this 8-axis ‘turn and burn’ machine. It gives us the facility to offer a new service to the market.”

Sodick’s ALC600G range of machines that are referred to as ‘turn and burn’ comes with a new standard – the ‘iGroove’ edition with a wire rotation mechanism. This patented innovation rotates the wire during the skim-cut operation so that workpieces are machined from top to bottom with the ‘unconsumed’ surface of the wire. Conventionally, wire electrodes are controlled solely by tension and running speed, while being constrained by a die. Sodick’s iGroove rotation mechanism provides additional control over the wire, resulting in increased surface quality and improved geometric accuracy, whilst at the same time minimising wire consumption.

From a specification perspective, the machine incorporates linear motors and absolute precision linear scales in the X, Y, U and V axes with an X, Y and Z axis travel of 600 by 400 by 350mm and a U and V axis movement of 150 by 150mm. With a maximum wire speed of 420mm/sec that cuts with speed and precision in a 1050 by 710mm work tank, the ALC600G is a precision high-speed performer with a compact footprint to suit any machine shop.

🎧 Robot loaded Nakamura just keeps running

UK subcontract machine companies don’t get much bigger than Metaltech Precision Ltd in Somerset. As part of the Expromet Technologies Group, the Metaltech facility has been expanded on multiple occasions to reach its expansive 50,000sq/ft site that is home to more than 40 CNC turning centres, more than 15 machining centres and a wide variety of conventional machines, fabrication equipment and metrology technology. However, the latest machine to be installed was a Nakamura-Tome WT-300 with an automated robot loading facility from the Engineering Technology  Group (ETG). 

As a company that operates in the aerospace, defence, automotive, marine, oil and gas, rail and marine industries, the Chard-based company has more than 80 staff that are dedicated to delivering exceptional quality products from prototypes and small volume work to larger production runs on its sliding head turning centres.  

Discussing the acquisition of its latest machine tool, the Nakamura-Tome WT-300,  Steven Ward from Metaltech says: “We purchased the machine last September and it was installed by ETG along with support and ancillary equipment from Hydrafeed.”

Alluding to why the company needed the machine, Steven continues: “A customer approached us with a substantial contract. We identified the requirement to machine a significant number of parts. Although we have existing fixed head and sliding head turning centres, we are conscious of how we utilise our personnel and the hours available to us in a normal working week. The Nakamura solution allows us to operate well outside our normal operating window. The cell works on the basis that the Nakamura with its performance monitoring along with the Hydrafeed Robojob system allows us to palletise either billets or we can bar feed the machine. That enables us to extend our running for lights-out machining, as our normal operating window from 6am to 6pm leaves us with a 12-hour dead period.”

With through spindle bar capacity options for bar feeding of 65, 71, 80 or 102mm and a maximum turning diameter of 270mm, the twin-spindle twin-turret Nakamura-Tome WT-300 is perfect for accommodating the bar turning and billet loading demands of Metaltech. Available with an option of the 15/11kW or 18.5/15kW spindle motor on the main and sub-spindle and a maximum turning length of up to 780mm, the heavy-duty Nakamura-Tome WT-300 is the perfect all-rounder for any machine shop that demands the utmost in precision and productivity on a sturdy foundation that will inevitably improve component quality and consistency. 

Discussing if the automation route is the only way to remain competitive, Steven adds: “I think businesses must consider automation in general. You have two expensive assets in the business, one is your machinery and the other is your personnel. You have to consider how you best utilise both of those assets. Considering the skill set of staff, you have to understand and ask if they are better utilised on more complex tasks that are maybe smaller batch volumes or 1 and 2-offs. In essence, do you need them to stand there and do a 1000-off, putting a cherry on the cake.” 

Highlighting how the staff are utilised with the Nakamura-Tome WT-300 automation cell, Steven says: “We have several people in the machining section trained to come up to check and monitor the machine. The machine itself has a very stringent monitoring facility within it, so even the slightest problem and the machine will alarm out. We are also able to operate outside normal working hours because we have remote access to the machine via its software. So, we can actually see what is going on via the axes loading technology and deal with any issues from there.”

Looking more specifically at the Nakamura-Tome WT-300 and why it is the ideal solution for Metaltech Precision Ltd, Steven adds: “We gave consideration to other manufacturers before going down the Nakamura route. However, there were a number of factors that came into it and it was not necessarily a cost-based decision. Our decision was based on performance and availability and how that fits into the model of our business.”

🎧 The wait is over

The EMO exhibition in Hannover has finally arrived. From the 18th to the 23rd of September, the world of manufacturing will descend upon the German state of Lower Saxony for what promises to be a very welcome return for the show after a four-year hiatus. As Europe’s most prominent machine tool exhibition, the bi-annual event will open its doors under the motto ‘Innovate Manufacturing’ and more than 1,750 exhibitors from 42 countries will be presenting their latest innovations, strategies and solutions that stretch the full spectrum of business, connectivity and sustainability topics in the production engineering arena. 

Show organisers VDW embarked on a ‘world tour’ throughout the summer to emphasise both the relevance and importance of the exhibition to the global manufacturing industry. When the touring party hit the UK in May, Dr Wilfried Schafer, the Executive Director of EMO organiser VDW (German Machine Tool Builders Association) was keen to emphasise the importance of the show on the world platform and how the technology could have a positive impact for UK manufacturers. 

As the world’s leading trade fair for production technology, the international event claims to think way outside the box in both social and technological terms. To this end, EMO Hannover is focusing especially on the megatrend of sustainability – a topic that is of particular importance globally. Alongside the optimisation of numerous organisational processes, the complete machining of components is one of the main technological solutions for making production more efficient and consequently more sustainable. Under the ‘Future of Sustainability in Production’ banner and on the joint stand of the same name, EMO Hannover 2023 is dedicating itself to the topic of sustainability as a task that society as a whole needs to address.

Climate, environmental targets and the scarcity of certain raw materials are now making a rethink necessary – and all will be discussed in the ‘Future of Sustainability in Production’ trend topic at EMO. Based on the current production technology methods, the manufacture of steel, aluminium, plastics and cement alone would generate about 800 gigatons of CO2 in the 21st century, calculates Prof. Dr Holger Kohl, Deputy Director and Head of the Corporate Management business unit at the Fraunhofer-IPK (Institute for Production Systems and Design Technology), Berlin. This would mean that the two-degree target of the Paris climate agreement would already have been missed. That is why it is so important for such materials to be recycled in some kind of circular economy, emphasizes Kohl, who is also a member of the German Academic Association for Production Technology (WGP). 

As a rule, machine tools are already designed to give many years of trouble-free profitable operation. However, in the case of lathes. milling or grinding machines, the following also applies: “The amount of time it takes for the precision and reliability levels to diminish depends on the basic design of the machine, how heavily it is used and how well it is maintained,” explains Paul Kössl, Global Head of Business and Marketing at the international United Grinding Group, headquartered in Switzerland, which will be showcasing various brands at EMO. 

Of course, EMO isn’t all about sustainability – but it is becoming increasingly prevalent. If you’re making a trip to the show from the UK, you need it to be justifiable to your business – and this is why process optimisation and productivity will be on the lips of most exhibitors and visitors alike at the biannual tradeshow. Most precision tool specialists and manufacturers of grinding and machining centres are very familiar with process optimisation. So, at EMO industrial and scientific experts will be showing which manufacturing technologies are available for the complete production of even highly complex components via a complete programme of seminars. 

In Hannover, visitors will be treated to practical presentations on a huge variety of technically optimised processing possibilities that are aimed at making production more sustainable and profitable. Around 30 member companies of the VDMA Precision Tools and VDMA Measuring and Testing Technology have registered to deliver presentations at EMO on the topics of machining, clamping technology, measuring and testing technology, OPC UA and digitisation. So, if you are heading over to Hannover this month, it may be worth taking in some of the technical presentations as well as seeing the almost endless range of innovative new technologies.

Reducing vehicle emissions

“Reducing mass is an effective way to reduce vehicle emissions,” according to the International Council of Clean Transportation (ICCT)’s Fact Sheet Europe Report. The onus is on automotive manufacturers to produce more weight-efficient components. Yet heavy cast iron and forged steel remain popular and manufacturers must design and engineer these ‘heavy’ metals into being weight-efficient. Here, Sangram Dash, Product Application Manager for Indexable Milling at Sandvik Coromant, explains why lighter and closer-cutting shoulder milling and face milling tools are the answer.

Further to the ICCT’s findings, McKinsey & Company’s ‘Lightweight, heavy impact’ report offers in-depth calculations as to how lighter vehicles emit fewer CO2 emissions:  “Lightweighting measures can help reduce CO2 emissions to a certain extent (approximately 0.08g CO2 reduction per kilogram saved). If an OEM manages to reduce the vehicle weight by 100kg, it saves approximately 8.5g CO2 per 100km.”

In response to findings like these, automotive manufacturers are turning to ‘lightweighting’ to facilitate better fuel efficiency and handling. Lighter metals like aluminium and magnesium can help in this regard, but lightweight is about more than simply choosing whichever material weighs less – especially when heavier materials are still widely used in vehicle manufacturing. 

Manufacturers must design and engineer these metals into being a weight-efficient and strong alternative to lighter metals. This means producing more complex, near-net-shaped parts based on more complex designs, which is tough when producing ISO-K materials that are more difficult to machine. What’s more, all cast irons contain silicon carbide (SiC), which is very abrasive to the cutting edge. When there is a need to produce a variety of components – shoulder milling is the best approach. The basic-yet-versatile milling application ensures a lighter cutting action that minimises impact on the tool and ensures the component stays in shape. With shoulder milling, the tool creates a plane and shoulder surface, simultaneously. 

A ‘light touch’

Generally, 90-degree milling angle inserts have eight edges – four on the front and four on the back to produce the shoulder and plain simultaneously. Sandvik Coromant felt there was room for a new shoulder milling concept; one that would bring greater productivity, tool-life advantages and economic benefits for OEMs.

In response to the above challenges, Sandvik Coromant developed its CoroMill® MF80 inserts. Designed for automotive milling applications in ISO-K and ISO-P materials, the inserts have eight cutting edges, chip protection and an optimised micro geometry. The tools are designed to be ideal for thin-walled components and machine setups with limited stability. The cutting edge is inclined for smooth cutting action and to promote low cutting forces. This gives better security and chip evacuation, as well as a wiper edge for a superior surface finish.

CoroMill® MF80 isn’t entirely new, but based on a technology platform similar to Sandvik Coromant’s existing Coro-Mill® 345. This new milling concept offers a 40% lighter cutter body with shim protection and a high number of inserts for secure and stable machining, even in vibration-prone overhang applications. 

Performance tests 

In one case, CoroMill® MF80 was run against a competitor’s mill in a rough shoulder milling application to produce pump and valve components from an ISO-P carbon steel part. The mills were run with identical cutting data with one exception, the competing mill was run at 375mm/min and CoroMill® MF80 was run at 600mm/min. The CoroMill® MF80 gave a productivity increase of 60%. The competing mill produced nine components while CoroMill® MF80 produced 15. As for tool life, the  CoroMill® MF80 gave a tool life increase of 67%. The key advantage for the customer was that the mill’s shim protection and the high number of insert edges can lower the cost-per-part in roughing or shoulder milling.

Automation supports growth

An increase in annual turnover from £3m in 2016 to £8m has been reported by contract machining specialist Unicut Precision Engineering, Welwyn Garden City, which has spent £1.7m in the last two years on new production and inspection equipment. 

About half of the investment went on two more Cincom sliding-head lathes and two additional Miyano fixed-head lathes from Citizen Machinery UK, bringing the totals of the bar-fed lathes on site to 24 and 11 respectively. The remaining funds were used to purchase three new items of inspection equipment and to extend the automatic pallet storage and retrieval system linking three 5-axis machining centres on-site.

Jason Nicholson, Owner and Managing Director of Unicut commented: “Efficient production is not just down to automation but also depends on how well you monitor the machine tools on the shop floor and use the data to make informed decisions. We use PSL Datatrack to help with this and will shortly be progressing from manual extraction of production data from our machine tool controls to directly downloading it over a network for remote monitoring.”

Regarding turning, which currently accounts for 85% of Unicut’s turnover, he said that standardisation on Citizen lathes with their user-friendly, intuitive Mitsubishi controls greatly helps to mitigate the current shortage of skilled setter-operators, which he sees as a worldwide problem. The use of this CNC system throughout the factory also speeds up the training of staff and allows operators to swap easily between machines. 

The latest turning centre additions were two 65mm bar capacity Miyano BNE-65MYY models, each featuring a pair of Y-axis turrets and the latest Mitsubishi 15-inch touchscreen control. They joined five smaller fixed-head lathes in the same series to form a seven-machine cell for producing hydraulic and pneumatic components in large volumes, typically from 2,000 to 10,000-off. 

Mr Nicholson continued: “Flexibility of production in a contract machining environment is crucial, as it is the key to profitability and to being able to compete with subcontractors in low-wage countries. Having two Y axes in the latest BNEs rather than one enables the preparation of programs that closely balance front and back working cycles at the main and sub spindles. 

Each turret has 12 live stations, so an extensive variety of milling, drilling and other driven tool operations can be carried out in-cycle, almost always enabling one-hit production of parts. Sometimes prismatic machining accounts for more than 90% of a cycle, so at first glance, the components look as though they have been produced on a mill. Mr Nicholson is also a long-time user of sliding-headstock lathes from Citizen Machinery, having bought his first one in 2000. In 2018, he was an early adopter of the lathe manufacturer’s LFV (low-frequency vibration) software, which was included in the operating system of the Mitsubishi control on one of two 12 mm capacity sliders bought in that year. 

At the time, he said that the ability of the programmable function to break stringy swarf into shorter chips was eliminating the need to periodically stop the lathe to clear away clogged swarf, raising productivity. The LFV lathe was therefore left with the confidence to run unattended, including overnight and at weekends, even when turning ductile metals and plastics, increasing throughput further. Impressed with the trouble-free performance, he bought two similar, improved versions of the lathe with LFV in 2022. 

Mr Nicholson concluded: “On this type of machine, productivity is all about getting the material to chip because otherwise, you have to keep stopping the spindle to remove swarf from around the workpiece and tool. On a fixed-head lathe, it is possible to increase the feed rate to promote chipping, but that is not possible when turning smaller diameter parts on a slider. With LFV programmed correctly, the swarf never fails to chip whatever the material, even when OD turning long components.”

Shop floor monitoring boosts productivity

Remotely checking the status of machines on the factory floor is helpful for production managers to understand the reasons for idle times. One subcontractor using monitoring software that feeds data back from the shop floor to an office is aerospace subcontractor Automatic Industrial Machines (AIM) in Clevedon, North Somerset. Its three 5-axis machines (YCM, Hedelius and Mikron) and nineteen 3-axis and 5-axis stand-alone machines are all controlled by Heidenhain CNC systems that have been networked using the StateMonitor software.

Detailed knowledge and data collection for immediate troubleshooting and analysis has increased output considerably. Stoppages can be rectified quickly, while analysis over time allows the company to try out different methods for increasing throughput. Operators know the software is installed and relaying information on their actions over the network, so productivity tends to be higher. Long-term records are also useful for planning machine maintenance. Rob Kendall, Managing Director of AIM said: “Having access to data in real-time is what Industry 4.0 is all about.”

One automated YCM NFX380 5-axis machining centre served by an Erowa Leonardo pallet storage system showed that over 24 hours of unmanned running, depending on the components and the cycle times was often idle for the last three to four hours as it had run out of work. Six extra Erowa pallets were purchased, bringing the total capacity to 66 positions. This enables the cell to run for a full 24 hours. The extra parts produced per day have quickly started to amortise the cost of the additional pallets.

Mr Kendall is a long-time user of Heidenhain-controlled machines and the subcontractor was chosen in 2018 as a beta test customer to evaluate an early version of StateMonitor. Since then, Heidenhain has invested heavily in the development of StateMonitor software. The product is now fully fit for purpose and when it was presented to Mr Kendall in the latter part of 2022, it had progressed to such an extent that AIM was happy to evaluate it again. By January 2023, the subcontractor had purchased 22 licences for all the machining centres on the shop floor.

Heidenhain provided a turnkey service, during which the software was installed on AIM’s server where all programs are resident. Every machine’s Heidenhain TNC control is connected by an Ethernet cable. Two of six factory units communicate with the other four units over Wi-Fi to allow server access to data from remote machines.

85% of AIM’s turnover comes from the aerospace sector with the company producing aluminium structurals such as stringers and skin panels up to 6.5m long. The subcontractor additionally supplies the automotive, motorsport, electronics, food processing and fluid control industries.

Dave Kinch, Operations Manager at AIM, takes a pragmatic approach to his use of StateMonitor. Although 22 machining centres are connected, he tends to focus on five or six, notably the three automated cells, one or two stand-alone 5-axis machines and a machine devoted to titanium aero components. Regarding the latter, he noticed cutting parameters were 1% below optimal and adjusted them accordingly. It represented a small rise in metal removal rate, but over a year it is adding up to a measurable increase in throughput. 

A vast amount of additional data is available, including job changes, program status and run time, tool changes, spindle speed and feed rates, override settings and other machining parameters, all of which may be useful for some companies. 

“I have calculated that the YCM NFX380 5-axis production centre, served by the recently expanded Erowa Leonardo store with 66 pallet positions, is already 26% more productive due to the changes we have implemented based on information collected from the StateMonitor software.”

He added that the output from stand-alone machines is more difficult to assess, but he estimates that they are producing parts during the day shift for 83% of the time, versus an industry average of 65%.

A prototyping powerhouse with HAAS at its core

Located in the scientific hub of Cambridgeshire, Velocity Precision has recently undergone significant expansion under the guidance of its founders, James Brown and Glen Dawson. With a decade of experience and the initial purchase of its first HAAS machine funded by personal loans, the company has now grown to a team of 15 and has effectively doubled the size of its premises.

Specialising in prototyping for the high-tech and scientific industries, James and Glen work closely with design consultancy companies taking CAD drawings to the finished product. The pair were working together at a local company when they decided to set up their own business. “We wanted the independence to make our own decisions and to progress our careers. We had both worked on HAAS CNC machines previously, so we knew them to be dependable and user-friendly. HAAS was the obvious choice for us and our first machine purchase was a Mini Mill,” explains James.

Velocity Precision has a state-of-the-art facility and a focus on precision and innovation. This enables them to meet the needs of their clients with high-quality, dependable results.

“Our customer base is increasing, so we have been investing in more machines,” James stated. They began with their original Mini Mill and progressed to a HAAS VF-2 VMC, followed by a Super Speed VMC with a 12,000rpm spindle. They also installed two HAAS lathes, to make use of Glen’s turning expertise. Additionally, 4-axis rotary tables and 5-axis trunnion units have been added, and the latest acquisition, a HAAS UMC-500, uses the skills honed on their existing machines to gain the full potential from the machine’s 15,000rpm spindle, full 5-axis capability and 30-station side mount tool changer.

“Our first step into 5-axis machining was with the HAAS TRT160 trunnion. The impressive surface finish and increased speed it gave us translated into more enquires for that kind of work. We can use high feed rates on 3D machining and the speed is phenomenal; we can do so much more in one operation. Word gets around quickly, and we’re winning quotes simply by owning the machine. The footprint is the same as our VF-2, a small mill, so it takes up very little space for the parts it produces.” 

HAAS’ Tool Centre Point Control (TCPC) and probing capabilities are powerful tools that enhance precision and efficiency in machining. TCPC allows the machine to precisely locate the centre of rotation for rotary axes, which is crucial for accurate 5-axis machining. Meanwhile, probing enables the machine to quickly and accurately measure workpieces, tool lengths, and even detect broken tools, all without manual intervention. By automating these processes, HAAS machines can achieve greater precision and speed, reducing setup times and minimising errors. 

Velocity Precision’s prototyping services encompass a wide range of applications, from the development of specialised robots that can spray insulation under floorboards to the production of a torsion bar for the new Ford GT. “We made the prototype bar and the customer was so impressed they have just signed a massive contract. Being able to offer 5-axis machining has allowed us to win that business,” explains Glen.

 “HAAS have always made machines which are easy to use; the controls are universal so moving from one to another is a breeze – even from mill to lathe. The bed is just the right height and the windows let in a lot of light. Now with the Next Gen control, they’ve gone to the next level. The increased memory means more programs can be stored and we can create directories now, which keeps everything tidy. We can keep all our regularly used programs on the machine, even for 3D parts. It’s like storage on a computer in that respect. We use the VM-3 for the highest tolerance work because it has the tightest ballscrew pitch. We’re machining up to 0.001mm.” The VM-3 vertical mould maker has a generous work envelope, a multi-fixturing table and a 12,000rpm inline direct-drive spindle.

🎧 Tow-Trust raises the bar with Bystronic

Evolving from a husband and wife ‘start-up’ company to the UK’s leading manufacturer of towbars, the 30-year journey to success for Tow-Trust has been built upon an ethos of providing products of unparalleled quality at competitive prices. Starting with little more than a small ambition and tremendous drive, Ian and Elaine Miller grew the business from its small single unit in Atherstone to a 60,000sq/ft site – and the mantle is now being taken forward by sons and fellow directors Tom and Alan Miller. 

Since its 1991 inception, the business has grown exponentially in terms of staff, product lines, components and market share. The Warwickshire manufacturer now employs 86 staff and produces towbars for all leading vehicle and motorhome brands with an accessory list that encompasses everything from spacers and steps to height couplings, adaptors, connectors, bumper protectors, chassis extensions, tow balls, socket plates and much more. With a continually expanding business and a position as the UK’s marque towbar manufacturer, the company has invested heavily in the latest technology and automation – this includes a multitude of machines from Bystronic. 

As the CEO of Tow-Trust Towbars, Tom Miller says: “We manufacture over 3000 part numbers and ship hundreds of thousands of units every year. The manufacturing process starts at two different times, we have the hollow stock section and the sheet steel divisions. The sheet steel division runs the very latest in technology with laser cutting and automation. From here, we pass the products through press braking and welding sections to the ‘work-in-progress’ holding area.” 

The sheet steel division is home to a wealth of technology from Bystronic with the area having three Bystronic press brake machines, the Xpert 40, Xpert 80 and Xpert 200 all lined up next to a Bystronic ByStar Fiber laser cutting machine.  Adjacent to the four machine line-up is another ByStar Fiber laser cutting machine, this machine is continually processing sheet steel credit to the Bystronic ByTrans 3015 extended automated sheet metal loading facility that minimises operator intervention.

The company also has a ‘hollow section’ division. Discussing this area, Tom continues: “This department also runs the latest technology. Here, we have the automated Bystronic ByTube 130 for cutting round and square tube material stock and alongside this is a custom-built AMOB CH120 semi-automated machine for tube bending. This gives us complete control over our product, which is essential as we work to very tight tolerances and we require the ultimate in quality.”

“When all the products have passed through our manufacturing phase, and the hollow section and sheet steel division complete their parts, components are then moved to the work-in-progress area. Here, we construct sub-assemblies and undertake our quality control process. This feeds our welding shop where we have 10 manual welding bays for small intricate parts and low-volume production parts. We also have four robotic bays for high-volume production.” 

Above the production shop floor resides the Design Centre and Test Division, it is here that the Tow-Trust team work closely with customers, vehicle manufacturers and its network of national dealers. Alluding to the role of this department, Tom adds: “Our in-house design team will always start by applying for the vehicle mounting point data from the vehicle manufacturer. Once we have this, we have the criteria to design and manufacture a product. From here, we will design a specimen and run it through FEA at the intended loads to check the product is capable of safely fulfilling its requirements.”

“When this has all been completed, we will fully check the manufacturing process through the Bystronic software. When we are happy that we can manufacture the part and that it will achieve its load requirements, we will then make a sample. We will get a vehicle to our facility and check the parameters, and we do this for every vehicle on the road. Once we have met all our stringent manufacturing criteria, we will put the system through its type approval phase. We have a single-axis test machine, which conducts 2 million cycles and we have a Carlos test machine that is a 93-hour test – safety is paramount.”

When all the parts have moved through the production cycle, they are then shot blasted, pre-treated and e-coated (Electrophoretic coating) with an industry-leading e-coat finish that has 1200-hour salt spray corrosion performance. Upon completion, the part is then passed to the packing division, as Tom continues: “We pass parts down our bespoke automated packing line where we weigh the product, band it, and send it through a heat shrink tunnel. The parts are then transferred to our warehouse where more than 30,000 items are held in stock at any one time. We have commissioned our in-house warehouse management software to give us complete control of our stock management where we scan all inventory in and out from point-of-sale to goods in the lorry – we are in complete control.”

Concluding on the business, Tom says: “The company has come a long way since 1991 when it was founded. My parents set the business up in a small workshop in Atherstone, and with the continuous improvement and investment plans that we have put in place, we have become the UK’s largest towbar manufacturer, which we are extremely proud of as a family-run business.

🎧 Dugard delivers the solution

Founded in 2005, DGF Engineering Ltd has been on a continuous growth trajectory and at every step of the way, the Hertfordshire manufacturer has turned to Dugard for its industry-leading machine tools. The company started its investment in Dugard machines with the Dugard 1000 3-axis VMC – this has since been followed by a SMEC SL 2000M turning centre and now a smaller Dugard 550 machining centre. 

The acquisition of the SMEC SL 2000M turning centre in 2022 was due to the turned components at DGF Engineering Ltd increasingly needing secondary milling operations on machining centres. To free up milling capacity, the Royston-based subcontractor that produces a diverse range of components for a variety of industry sectors believed the Dugard SMEC would make a major difference – and it has. 

Recalling why the company invested in a live turning centre, Liam Fernard from DGF Engineering recalls: “Turning work with milled features were tying up our CNC milling department for too long and we needed a solution with live tooling. As we were happy with the service that we received from Dugard on our Dugard 1000 3-axis VMC, we naturally looked at their lathes and the SMEC SL 2000M turning centre ticked   all the boxes.”

With the service, support and reliability of Dugard being as robust as the machines, the company turned to Dugard once again when it needed additional milling capacity. Discussing the latest acquisition, Liam says: “We bought the Dugard 550 for several reasons, one being the small footprint. We didn’t have a huge amount of room and the machine that the Dugard 550 replaced was only a small machine. A lot of the work we do is quite small components, so we didn’t need a big bed and big footprint machine like our Dugard 1000. So, this machine ticked all the boxes and it fits exactly where we wanted it.”

Discussing the work the company is machining at present, Liam says: “As a subcontractor, we will typically machine anything, but our main industry focus is the scientific, liquid and gas testing industries – but then we could also be doing work for a farmer down the road.”

Looking at the materials the company machines, Liam continues: “We machine a wide range of materials that include aluminium and stainless steel, and for a small machine the Dugard 550 handles stainless very very well. The machine has a 10,000rpm spindle, the horsepower is very good and it will cut all day long.” 

Referring to why the company has purchased yet another Dugard machine, Liam adds: “We have been really impressed with the first two Dugard machines we bought and the service has been great. The machine it replaced was getting a little bit old and the spindle was only 6000rpm, so it just wasn’t machining how we really wanted to. From experience, the first place for us to go was Dugard to see what they had available – the Dugard 550 ticked all the boxes.”

From order to delivery, the machine was on the shop floor in a matter of weeks. As Liam continues: “The machine was a stock model in their showroom and as soon as we were interested, we paid a deposit and it was just a case of sorting things out here to make sure we could get the machine placed. Dugard delivered the machine and took the old machine away and they re-sited another machine for us – it was all done and dusted in 1 ½ hours. As a company, Dugard understands we have to make money and downtime loses money, so they do everything in their power to get us up and running as quickly as they can.” 

The company is programming its machines with an off-line CAM system, alluding to this, Liam says: “The latest machine fits in easily, just like the other machines. There is a post-processor for the machines, so you don’t have to make any changes. Additionally, we have a mist filtration system on the latest machine. We were debating whether we needed a filtration system, but to make sure we were compliant with legislation, we installed a Dugard filtration unit on the Dugard 550 machine.”

In conclusion, Liam says: “The machine was delivered with the filtration system already fitted, and as we were very happy with immediate results, we asked Dugard to retrofit filtration systems to our other machines. This was done a day after the Dugard 550 machine was delivered and installed. The service has been fantastic and whenever I speak to anyone who is looking for a machine, I always recommend Dugard because they haven’t put a foot wrong for us. There is nothing that is too much trouble for them and they will help you out as much as they can.”

Armeg is tooled for success

As a brand, Armeg power drilling tools are stocked on shelves in hardware stores and retail outlets the world over. With a product range that encompasses everything from masonry, wood, metal and tile drills to hand and power tools, saw blades, screwdriving products and more, Armeg has been designing and manufacturing products since 1973. 

With over 600 products in its armoury, Armeg is utilising sliding head turning centres from Star to enhance its throughput. Looking at one specific product that has given the company manufacturing issues for several years, Armeg’s Paul Bentley says: “The product is very challenging to make and we used to produce it in three operations that included turning, then shanking it, and we had issues getting it off the machine. It was costly and a challenge to serve our customers, and we pride ourselves on price, quality and service. We can now produce the party in one operation.”

“We have also just launched a roofing bolt driver and if it wasn’t for the Star machines, we wouldn’t have been able to get that part to the market. It is a price-sensitive product and the cycle times and technologies on the machine have enabled us to get that roofing bolt driver to market.”

Looking at how investment in a Star SR and two Star SW machines has brought business to Armeg, Andrew Grafton from Armeg says: “If I am trying to secure new business and we come back to the factory and we cannot physically manufacture it, that can be down to simple manufacturing capabilities we cannot accomplish. It could be that we cannot manufacture the parts cost-effectively, or we may simply not have the capacity.”

Discussing the process of buying sliding head turning centres from Star, Andrew says: “We originally invested in a Star SR machine which we got for a certain product. It was fantastic. We realised how versatile the machine was and we were loading it with new products all the time, but we quickly discovered that capacity was filling up on the SR machine. We needed to relieve capacity and we discovered that the Star SW-20 machine was a lot better suited to some of our new products and the geometries of those parts.”

Alluding to this, Andrew says: “The SR machine is very versatile and will let us go up to physically larger components to 38mm diameter and on the smaller components, it is like a jack of all trades. We need to churn the products out at a much higher rate and the SW-20 machines allow us to do that. They have more axes and more capabilities. The machines have three-channel programming and machining that essentially allows us to have three different cuts on the material simultaneously. So, on a standard sliding head lathe your cycle time may be five minutes, but with the SW-20 you can reduce that by two-thirds by having three cutting tools working simultaneously.”

The company initially bought one SR machine and within a year, it bought a second machine. Mentioning this, Andrew continues: “We went for the SR machine originally, which was fantastic but with new product lines – the SW machine was better suited to our parts. There was one product we took on only because we had the SR machine – and we managed to produce it in three minutes. The SW machine sliced that cycle time in half, but as we released more products and need more capacity, we needed to buy another SW machine.”

The company also utilises the Step Cycle Pro (SCP) feature on its Star machines, as Andrew adds: “We are now starting to run low on capacity on the new machine, so we had to go for SCP. This swarf control system works via oscillation to control the length of the chips. The main problem running these machines lights out is swarf control, so the operator may set the machine and an hour after he has gone home, the machine stops due to swarf issues. We have worked out that over our vast array of components,   SCP actually increases our capacity by five hours every single night of the week. This is extra capacity that will help us to grow our business.”

🎧 EKC Group buys 25 machines from XYZ for apprentice training

When the East Kent College (EKC) Group was awarded £500,000 of government funding for the integration of the new 2-year T-Level courses that are taken after the GCSE stage, the astute leadership team at EKC Group invested wisely – buying 25 manual and CNC machines from XYZ Machine Tools. 

The T-Level courses have been developed in collaboration with employers and education providers, so the content meets the needs of the industry – preparing students for entry into skilled employment, an apprenticeship or related technical study. Following a tender process that was instigated by EKC Group, it was decided that the best route to preparing young learners for a future in engineering would be training them on machine tools from XYZ.

Undertaking everything from teaching, training, maintenance, health and safety compliance and learner engagement, Craig Munn, Deputy Head of Engineering at Canterbury College says: “Our campus has approximately 1500 students and in the engineering department we have 155 students and nine staff. In 2021, we received £500,000 in government funding towards the new T-Level qualification. This has resulted in us buying computerised CNC machines that will get our learners ready for industry. The best way to use this funding was to invest in XYZ machines, so we purchased 25 machines from them. The machines are dotted across the Canterbury, Ashford and Dover campuses of the EKC Group.”

“Whilst there are similarities between the machines that create familiarity, they differ in their capabilities. This means the machines are perfectly placed for their intention of preparing students for integration into the industry. This familiarity also enables our learners to seamlessly work across different campuses and use all of the different machines,” adds Craig.

Tom Marshallsay, the South East Area Sales Manager for XYZ Machine Tools comments: “The college came to XYZ as they realise we are very well established in the educational sector as well as in industry. The EKC Group compiled a tender where XYZ was put against other machine tool companies. As we engaged with the college more during the process, there was a realisation that there were considerable benefits from working with XYZ.”

Looking at the different machine tools and packages supplied by XYZ, Tom continues: “There is a mixture of ProtoTrak and Siemens CNC control systems across the machine tools. This provides integration with industry-standard platforms. From a machine perspective, we have the XYZ 500 LR machining centre and the XYZ CT52 LR turning centre both at Ashford and Dover campuses. Ashford also has an array of manual machine tools. We also have another couple of machines in Canterbury, such as the XYZ RMX 2-OP and the XYZ 1530VS manual lathe.”

Alluding to why XYZ won the EKC Group’s business, Tom says: “The reason we won the business is largely down to the control systems and the simplicity of the machines. The fact that the machines and the control systems are industry standards means that students can come to the college, become competent and confident with the machines and then go straight to industry and run machines, which is perfect for both college and employers. Many engineers didn’t get that opportunity when they were at college, so this is significant for learners in the area. In addition, the service and support that XYZ provides to college staff and how we train the staff to use the control systems is a huge benefit.”

The Apprentice Opinion

Serving his apprenticeship at the renowned MJ Allen Group and undertaking training at the college, Takudzwa Chauruka says: “I drive from Ashford to Canterbury College to study machining, which I do on the new XYZ CNC machines. The machines are very good as you don’t have to excessively concentrate on programming, as the CNC machines are mostly conversational. So, all you have to do is put in the numbers and parameters you want, and the machine will do the rest. What else is really good is offline programming. You can program on a computer remotely and then send the program directly to the machine.”

“From the perspective of the manual machines, we get to learn the fundamental basics and with the CNCs, we get to do more complex tasks like rigid tapping, which you mostly cannot do on a manual machine. The CNC machines also help apprentices learn how to make complex parts that may have concave profiles. One of the things I love about the XYZ ProtoTrak is that it has a DXF converter that makes it easier to use when programming. All you have to do is import your drawing, and the machine then does the rest.”

“Compared to the machines I use at work, the XYZ machines are much easier to use as they are smaller and easier to work with. In the future, I am hoping that we can have some of these machines at MJ Allen.”

Adding to this sentiment, fellow college trainee Liam Harkett, an apprentice at Instro Precision in Sandwich, says: “I am an apprentice machinist using manual lathes, milling machines and CMMs. I have a basic understanding of the XYZ machines and I use them for machining small and relatively simple parts. I’m learning to set datum points, program the machine and also understand how to use conversational programming. By using this, I can tell the machine what to do and it writes the programme for me. I prefer this over the previous method where you would have to input the exact programming instructions into the machine – this makes programming a machine much easier and more efficient. The ProtoTrak control panel is very user-friendly and it is an excellent concept for apprentices to use.”

Liam continues: “In my workplace, we have a wide range of CNC mills and lathes and this includes 3, 4 and 5-axis machining centres and a 3-axis live tooling lathe – but none of them are as easy to program and set as the XYZ machines at the college. This is down to the XYZ ProtoTrak and the conversational programming.”

Looking at the primary benefits of installing XYZ machines at the different campuses across Kent, Craig Munn from EKC Group concludes: “We have installed these machines to train the next generation of engineering employees and employers. We also need to fill the skills gap that is currently in the market. We chose the XYZ machines because they really work everywhere. They have equipped our apprentices and our full-time learners to be able to get a job in any machine shop out in the industry. XYZ has also provided excellent technical help with the training of our staff, teaching the learners and being on hand with any technical issues we may have.”

“The learners were itching to use the machines from the day they were delivered – and the machines haven’t failed us, they have been superb machines to use. We are certainly happy that we have chosen XYZ,” concludes Craig.

🎧 PCD is no bore

When the Schlote Group built a new factory in Harzgerode, it was designed to mass-produce only a single part and MAPAL supplied all the cutting tools. By optimising the tools, the foundation has now been laid for a future with new products.

Schlote’s story begins in 1969 as a small workshop in Harsum, where the company is still headquartered. Today 11 companies with 1,800 employees belong to the Group. The OEM has eight factories in Germany and further manufacturing facilities in the Czech Republic and China. Schlote Group customers include big car manufacturers, system integrators and foundries with turnover stemming from engines, transmissions and chassis.

Successful cooperation with Trimet Aluminium already existed at other sites, manufacturing finished car components from cast blanks. The awarding of a contract for a major OEM component with very high quantities led to a joint venture between Schlote and Bohai Trimet in Harzgerode.

More than 4,000 clutch housings per day

The part being manufactured in Harzgerode is a clutch housing made of die-cast aluminium for two-litre engines. The bell housing connects the transmission to the engine. While the transmission side is the same on all the clutch housings, the other side is adapted to the respective car manufacturer’s engine. The differences are small, so the bell housing construction is 99% identical for all cars.

Schlote Harzgerode GmbH is producing 4,000 parts per day. At over 80% productivity, the modern factory exhibits a very high degree of automation. Around the clock five days a week, 120 employees work at the site. Production can be expanded to six or seven days a week if need be.

“The part is not only an adapter flange, but also the back of the transmission. The bearing seat thus requires the highest degree of precision”, explains Sebastian Swiniarski, Work Preparation Team Lead at Schlote. The part requires many bores with different tolerances.

MAPAL is entrusted with supplying PCD milling cutters, tap drills, reamers and an array of diverse drilling tools. “We offer our customers comprehensive solutions including the development of entire processes”, says Stefan Frick, MAPAL’s technical advisor to Schlote.

Successful improvement process

A watchful eye was kept on the implemented tools from the very beginning. Since Harzgerode went into operation, analyses have been performed continuously to find possible weak points and optimise manufacturing. Within the context of this continuous improvement process, Schlote and MAPAL have together managed to achieve longer tool lives, lower tool expenditures and higher production quantities over the years. While 3,600 parts were produced at most per day in the beginning, the limit has now been raised to 4,500 parts – without the need for further machines.

The newest optimisation involves deep-hole drilling for oil channels used to change gears in the automatic transmission. “We evaluate every month with our tool management system which tools have to be exchanged how often”, Swiniarski reports. “Time and again, the deep-hole drills have proven to be particularly sensitive. As these drills are relatively cost-intensive, we have concentrated on them to further cut our tool costs.” 

In this particular case, two of five deep-hole bores are involved with a diameter of 8mm and cutting depths of 180mm and 141mm. They run through the part from the side up to the bearing seat in the middle. Solid carbide tools were used for this up to now, which is standard for deep bores. Schlote was able to achieve a tool life of 2,500 parts in this way. The load monitoring of the machine already registered tool wear starting at 2,000 parts though, and burrs could be seen at the bore exit.

Significantly longer tool life with PCD

When it came to optimising the deep bore, Plant Manager Tino Lucius, a former MAPAL employee, suggested PCD variants. And so, the partners developed the idea of deploying a PCD tip for the deep-hole drills. There was a lot to consider during the implementation, Frick relates: “It is not possible to construct this type of drill entirely out of PCD. Besides the high costs, the brittleness of the material is a problem. There is also always the danger of chipping off the cutting edges during interrupted cuts. Good cooling must also be ensured as PCD is heat sensitive.”

For the new tool, MAPAL started with the existing solid carbide drill and inserted a PCD cutting edge at its tip. The structure of the tool is reminiscent of a concrete drill with a carbide tip. The manufacturers in Harzgerode are very happy with the PCD deep-hole drill’s tool life. While the solid carbide drill’s tool life ends after 2,500 parts, the PCD version keeps going reliably up to 15,000 parts. There is further scope for improvement in machining challenges, such as blowholes in the material and varying casting quality. The partners are currently working on this together. “We have occasionally been able to achieve a tool life of 40,000 parts. Naturally, we want to make this ultra-long tool life the norm,” Frick stresses.

The cutting data is the same as that of the solid carbide drill at a spindle speed of 8,700rpm, a feed of 0.3mm/rev and a cutting speed of 218m/min. The new drill’s potential lies in its considerably longer tool life, the resulting lower tool costs and the higher process reliability. Fewer tool changes also mean less machine downtime.

Production at Schlote in Harzgerode involves a total of ten manufacturing cells. Each cell is made up of three machines from the manufacturer SW, two W06 double-spindle machines and a one6 single-spindle machine. The parts are machined in three clamping setups, whereby the double-spindle machines handle the first two setups and finishing takes place during the third.

The future is electric

Clutch housing manufacturing at the site was planned to last at least eight years with a peak output of 1.1 million parts per year. This peak was surpassed in 2020. Production has been ongoing for five years in the meanwhile with 900,000 parts produced per year.

Due to continuously improved productivity and lower production quantities, there has been time to address future trends and produce different parts. The factory is already being modified for this purpose. The first of two new projects involves six different parts that Schlote is to produce for a hybrid model of a super sports car manufacturer.

In the other project, Schlote’s expertise as a clutch housing manufacturer is once again called for – this time for an electric car. Schlote draws from the trend toward electric mobility by supplying e-cars with transmissions as well. For an innovative model with three gears, the connection between the engine and transmission is to be produced in Harzgerode. Half of the factory capacity is currently being converted. The production of parts for combustion engines is to be ramped down to 50%. In future, hybrid cars will account for 10% and purely electric mobility for 40%. Schlote has already produced the first parts of the new projects.

🎧 Subcontractor ramps up productivity with DMG MORI

As part of the British Engines Group of companies, BEL Engineering was established in 2012 as a project-managed CNC machining business to cater for the growing demand for precision subcontract machining. Operating from its integrated manufacturing facility in Newcastle upon Tyne, BEL can manufacture components from as small as 3mm diameter to 50-tonne components for customers in a wide variety of sectors, including civil nuclear, defence, aerospace, marine and oil & gas. When the company needed to increase its productivity on a long-running project, it turned to DMG MORI for a solution. 

Discussing the solution, Paul Robson, General Manager at BEL Engineering Ltd says: “The cap-ex on the machines here is about £2.5m which is quite a substantial investment in the business. We purchased six DMG MORI NLX machines, two of them are gantry machines and the other four are barfed machines. We specified gantry-type machines for specific products to go through those machines and the longer we have those machines, the more we see what they are capable of. Realising the capability of the DMG MORI NLX Series has opened up more opportunities for us to put more products through the machines. They are capable of doing unmanned machining which is a great bonus to our productivity. The footprint of the machines is very small considering the amount of material that they can hold and the parts they can machine.”

Looking at a brake body that BEL produces for a sister company in the group, Phil Westgarth from BEL Engineering says: “The main problem with this part is that it needed around five operations to reach completion. There are a couple of turning operations where the dimensions and tolerances are tied. It then goes to a drilling operation where once again the holes are tied to each other and the diameters. After that, there are two grinding operations to hit the flatness and parallel tolerances. This used to cause a problem in processing times and backlogs were created in other areas. We were pushing parts onto machines that already had high workloads – this created a lot of bottlenecks. Our grinding cell was virtually overloaded, as was the milling cell and we were just pushing more work into those cells. There was also the issue that every time you had to reset a job there was another opportunity for error to creep into the process.”

Phil Westgarth adds: “Looking at the part, we were searching for an opportunity to complete them in a single process. This was the overriding aim of this journey. We needed to make sure that whatever process we put in place, was capable of meeting all the design tolerances required by the customer – ideally in one operation. The fact that the DMG MORI machines have a Y-axis allows us to machine all of the features in a single hit. This eliminated any need for further machining on the mill, and the Y-axis provides far better accuracy than just a C-axis lathe would do. On the DMG MORI NLX machine, it’s a full C-axis and it isn’t belt driven. This gives you higher accuracy and faster processing times.”

Looking back at how the company has evolved, Paul Robson says: “We were a little apprehensive about lights out machining and worried that we might come in the next day to hundreds of parts that would just go in the bin. However, we had support from DMG and we have worked through the processes and we are getting repeatability. This is positively affecting the productivity coming out of the machines and the quality we are delivering to customers.”

“It is these factors that are a reflection of why DMG MORI was chosen as our supplier. Initially, we weren’t sure if the machines could meet all of our capability demands, but the sales team and the engineers assured us that the machines could do the job – and they delivered.”

Managing Director at DMG MORI UK, Mr Steve Finn says: “One thing that impresses me at this company is how they have embraced one-hit machining. They don’t just machine parts from the main spindle to the sub-spindle, they also embrace workpiece handling with the gantry loading system as well. Parts are coming in as raw material and leaving the machines as finished components that are ready to deliver to the customers. This is super efficient.” 

Phil Westgarth continues: “Batch quantities are pretty high for our business and we don’t necessarily want somebody standing next to the machine for every job that comes off the machines. This is why we wanted accurate and capable machines that could control the process. It had to be a machine capable of giving us what we wanted and could hit all the tolerances in one go without any further operations. We are very pleased with the machines we have invested in. The DMG MORI gantry-type machines are for our larger parts and the four bar-fed machines are ideal for our smaller components. It really transforms the production of these parts, it is ‘night and day’ from where we were previously. We are now running 24 hours a day and five days a week in most cases – and the machines just do what they need to do.”

Subcontractor reaches new standard with Mitutoyo

Cwm Engineering Ltd has been on an acquisition trail over the last few years to target growth in high-tech industry sectors. As part of its journey, the West Wales company has invested in five machine tools in the last three years. Now, the company is implementing a dedicated inspection department with high-end metrology equipment – that is why it has just installed a CMM and a surface roughness machine from Mitutoyo.

With a machine shop full of turning centres and 3, 4 and 5-axis machining centres, Cross Hands based Cwm Engineering is aiming to expand its work with aerospace OEMs and Tier 1 manufacturers. To do this, it has just built a dedicated temperature-controlled inspection department with a Mitutoyo Crysta-Apex V 7106 CNC Coordinate Measurement Machine (CMM) and a Mitutoyo surface roughness machine. 

Founded in 2011, the ISO: 9001 certified company started its metrology journey like all subcontract businesses – with precision hand tools. In 2014, the business bought a manual Mitutoyo CMM. This was subsequently followed by two shop floor CMMs to allow operators to inspect at the side of the machines to prevent potential bottlenecks on the Mitutoyo CMM. However, Cwm Engineering realised that to win business from its OEM and Tier 1 target audience, it needed to stand out with a dedicated temperature-controlled facility with high-end metrology technology. 

Commenting upon this investment, Cwm Engineering’s Managing Director Malcolm Walters says: “To set ourselves apart from other subcontract companies, we recognised the importance of investing in a dedicated temperature-controlled quality assurance department. We are fully aware that when potential customers visit a subcontract manufacturer, they want to see a dedicated metrology department to instil confidence in their supply chain choices. When it came to selecting equipment for this dedicated department, Mitutoyo was the standout brand for our business. Mitutoyo is a brand that everyone knows and respects as an industry leader, and our previous experience with Mitutoyo gave us the confidence that it was the brand for our business. Our previous experience with Mitutoyo was exceptional.”

Cwm Engineering invested in a Mitutoyo Crysta-Apex V 7106 CNC CMM that was delivered in April along with a surface roughness machine. Alluding to why the company invested in the Mitutoyo Crysta-Apex V 7106, Malcolm adds: “We chose this machine as it has a measurement range of 700 by 1000 by 600mm that is packed into a small footprint. The compact footprint is perfect for our inspection department and the work area covers the diverse dimensions of the work we undertake.”

The Mitutoyo Crysta-Apex V 7106 is crammed with the latest technology and this includes Mitutoyo’s ABS linear scales, SMS capability for status and service monitoring and Mitutoyo’s renowned MCOSMOS software. The Crysta-Apex V 7106 is extremely accurate and fast with high acceleration rates which are credited to its lightweight bridge construction, temperature compensation sensors and the UC480 controller that supports the multi-sensor and SMS functionality (Smart Measuring System). With a digital step of 0.1µm, the machine has an accuracy maximum permissible error of (1,7+0,3L/100)µm with a 3D acceleration rate of 2,309mm/s2.

Discussing how the Crysta-Apex V 7106 will streamline throughput at Cwm Engineering, Andrew Ritchie, the Systems and Operations Manager adds: “When we are programming parts offline with our CAM system, we can simultaneously send the files to our CMM for programme creation. This ensures that the CMM programme is prepared and ready to inspect the parts whilst they are in production.”

As well as investing in the Crysta-Apex V 7106, Cwm Engineering also purchased a Mitutoyo surface roughness measuring machine. Alluding to this, Andrew adds: “Historically, we have used a sample gauge and this has proven reasonably accurate. However, our variation of work can require surface finishes from as high as Ra3.2 in general subcontract work to as low as Ra0.4 for parts in the electronics, communications and ultrasonic industries. In some instances where customers subsequently surface coat or treat parts, they require a surface finish of ‘“That” and not better’ – the new testing machine will certainly support us in such instances.”

🎧 Subcontractor’s success balloons with Ceratizit

The modern history of Ritchie Engineering Solutions began with J.A Ritchie in 1986, an engineer with a successful career in the design and manufacture of gas turbine jet engines. This engineering passion led the business to involvement in a host of pioneering projects from world record-breaking aviation attempts to the design and production of Victorian steam machinery. As the business has evolved, so has its plant list – but one thing that has remained a constant over the last 15 years of evolution is its relationship with cutting tool manufacturer Ceratizit. 

Now run by J.A Ritchie’s two sons, Alasdair and Duncan, the family has subsequently continued to run and develop the business with the same passion for engineering. Nowadays, the Manningtree-based company operates in a host of sectors that range from autosport and automotive to aerospace and other markets that demand high-end manufacturing capability. To manufacture high-quality components competitively, the company has invested in 3, 4 and 5-axis machining with technology from Bridgeport, Kitamura, HAAS, Mazak and Matsuura that is supported by CAM software from OPEN MIND and Renishaw probing for everything from job setting, in-process and post-process inspection.

Taking a look at the company, Duncan Ritchie from Ritchie Engineering Solutions says: “The business started with our father who initially designed and made steam engines in a shed that he built at the bottom of the garden. From there, he got involved in Richard Branson’s transatlantic hot air balloon crossing in the late 1980s, working on the thermodynamics of the burner design and the pressurisation of the capsule. We then started to commercially offer the hot air balloon manifold that burns propane – and to this day if you see the burner unit above the pilot’s head, that is where it all started for us.”

More recently, the Essex company has been involved in machining parts for automotive OEMs, motorsport rally clients, Norton motorcycles, aerospace OEMs, lighting companies and many more. Discussing how the company evolved to its current position, Duncan says: “Down the years there has been a lot of hard work and sleepless nights, but in practical terms, you progress and build on your quality and make quality your selling point. A key part of this is your relationship not only with your customers but also with your suppliers. That would be everything from your material supplier, tooling and suppliers of the machine tools, but significantly it’s going to be the cutting tool suppliers. We have been very lucky and fortuitous to have a fantastic supplier in Ceratizit and a support network via Adam Cross from Ceratizit.”

Looking at the 15-year relationship with Ceratizit, Duncan adds: “Back then we were in little more than a shed in a country lane that would put many suppliers off, but Adam turned up and he saw us for who we were. He absolutely assisted in supporting us with the right tools for the right job and he has continued to do so throughout our journey.”

The subcontract manufacturing company has a complete armoury of Ceratizit products and the Ceratizit vending solution, alluding to this, Duncan continues: “The vending solution is twofold effective. It’s fantastic that we can have the bread-and-butter tooling such as the inserts and regular end mills. This means we can program complex components with the knowledge that we have spare cutting tool products immediately available. We have a small workshop where space is at a premium and we don’t have the financial capacity to necessarily stock everything, so having the vending machine stocked up and ready to go is fantastic.”

Looking to the future and the ongoing relationship with Ceratizit that is so critical to the company’s success, Duncan concludes: “The relationship with Ceratizit will definitely continue for the next 15 years and beyond. It is nice to show the journey of where we have been and how we started, but it’s more important to look at the focus of where we are going. We are working towards various accreditations to have a trusted tool supplier like Ceratizit is an essential part of that jigsaw. They can help us to make our growth journey happen. It is a team effort that involves our personnel and our suppliers – and Ceratizit is a major one of those elements on our team.”

Ritchie gets a grip on automation

Livingston-based Ritchie Precision is a precision engineering business that specialises in the laser, medical, photonics, oil & gas, ultra-sonic, optoelectronic, and scientific instrumentation sectors. New investment in the most up-to-date DMG MORI CNC machines and Lang Technik Robo-Trex robotic palletisation system has almost doubled capacity and assured quick turnaround of prototypes and production parts for this Scottish manufacturer. 

With high tolerance critical components manufactured on-site, the manufacturing and QC areas are both temperature controlled to ±1°C. Working to tight tolerances, the company has invested in a range of DMG MORI DMU and DMC machining centres and NTX1000 mill/turn machines that are complemented by DMG MORI turning centres as well as a range of Hexagon metrology equipment. 

With a high-volume long-term contract being awarded to Ritchie Precision for the manufacture of intricate, multi-feature medical components, the company invested in DMG MORI’s DMU eVo series machine tools. The machines were specified with advanced features such as coolant-preheaters to help eliminate the manufacturing inaccuracies caused by coolant ‘shock’. So challenging were the precision specifications of the components, the new machine tools were installed in a newly refurbished, temperature-controlled factory.

The final elements that enable the new components to be produced in the required high volumes and within the specification are the highly efficient Lang Technik Robo-Trex automation systems that now serve each of the company’s new universal machining centres.  Working unattended and fed by the Lang Robo-Trex systems, the company’s DMU eVo series machines run throughout the day.  Then, before the end of each day shift the Robo-Trex trollies are restocked with batches of workpieces, enabling each machining centre to run unmanned throughout each night.

Discussing this, Greig Anderson from Ritchie Precision says: “We learned from our mistakes when we started working on tight tolerance jobs on machines without robots. We have to run the machines 24 hours a day once the machines are set, otherwise, temperature control can be a challenge and the sizes can deviate. This results in parts being scrapped. With the robots, we found the temperature control in the factory, and with the robots running the machines constantly that we can achieve the tolerances required at high volumes. We have guys that run the machines on a day shift and when they leave, it runs lights out every night and we can return in the morning to good parts.”

Ritchie Precision has identified that just a short stop in production for as little as 20 minutes can create a temperature deviation and the company has to then re-run the warm-up cycle before restarting production. With the Lang automation system accommodating two component trolleys, one trolley of parts can be removed whilst the second trolley is being utilised for production. As Greig adds: “We can be running the robot all day and when we get to the end of the day, we can pull the trolley out while the machine is still running and reload the trolley and put it back in the automation system, where it is set and ready to go again. This means there is no downtime.”

Looking at the setup of the automation system, Greig comments: “It’s a retrofit system where DMG MORI and Lang set the system up quite seamlessly. We can run programs that we have had for years and simply add a sub-program to initiate the robot. Everything was easy to set up and run – it was as simple as adding a sub-program and loading everything into the robot trolley and ‘off you go’.”

Incorporating a simple-to-operate touch panel enables easy control of the automated Lang Robo-Trex system and, as external access to the trolley is possible, production remains seamless as machining cycles do not need to be interrupted. Control of the zero-point clamping system can be performed pneumatically through the machine tool or mechanically through the robot.

Explaining the benefits gained, Greig adds: “By enabling our machining centres to work around the clock without stopping, our Lang Robo-Trex systems have allowed the maximum productive potential of the machine tools to be realised and impressive volumes of parts to be produced”. 

🎧 Milling for high surface finishes

In the metalworking industry, ensuring a high-quality surface finish has always been one of the main focus points in cutting tool development. This is also true for indexable face milling cutters. Despite significant improvements in the high surface quality of milled components, tool designers still believe that available resources have not yet been exhausted and that intelligent applications of the latest generations of advanced milling cutters can substantially improve surface texture further.

When considering an indexable milling cutter, the key factors that determine the quality of a generated surface are the cutter’s geometry and accuracy. Both characteristics are mainly related to inserts carried by the cutter.

Powder metallurgy advancements have enabled the production of carbide inserts with complex shapes to ensure optimal cutting geometries while maintaining substantially increased accuracy of sintered inserts. Not surprisingly, such advancements in technology have significantly improved the surface finish in face milling. However, when indexable milling cutters were successfully applied to machining high-strength materials, and manufacturers started to notice hard milling as an alternative to grinding, the metalworking industry started to demand higher surface finishes through their milling applications – obviously led by the cutting tool.

An indexable face milling cutter is a multi-tooth tool. More teeth = more productivity. This is an undeniable advantage of the cutter. But, in terms of surface texture, a large number of teeth may be a problem. A fine distinction in teeth protrusion leads to irregular feed for the teeth and contributes to chatter, which will ultimately affect the surface finish.

It is perfectly clear that insert accuracy can considerably be increased by grinding. Moreover, grinding provides a sharp cutting edge that is very important in maintaining cutting action and preventing plastic deformation of the metal in fine milling, which features shallow depths of cut. Ensuring a highly accurate cutting edge requires grinding both the top and side surfaces of an insert. This may cancel the advantages of powder metallurgy in generating complicated surfaces to provide the required rake and clearance angles along a cutting edge. To avoid such an adverse impact, tool engineers should be very resourceful when designing the inserts intended for fine grinding.

This may cancel the advantages of powder metallurgy in generating complicated surfaces to provide the required rake and clearance angles along a cutting edge. To avoid such an adverse impact, tool engineers should be very resourceful when designing the inserts intended for fine grinding. 

 An important factor regarding the tooth accuracy diminishing is the insert pocket in a cutter that has its own dimensional and form tolerances.  As a result, even for ideally precise inserts, teeth protrusion will vary within acceptable limits. Although it cannot ensure an extra fine surface finish when compared to grinding. A way to overcome this problem is by using a fly cutter that carries only one insert. The fly cutter that is successfully used in various milling applications facilitates a smooth and clean cut, providing excellent surface texture parameters. But then again, productivity, in this case, is far below multi-tooth indexable face mills.

How do we solve a difficult situation and find an acceptable balance between surface quality and productivity? The cutting tool manufacturer has developed several answers to this challenge.

An integrated wiper flat with a specially shaped minor cutting edge is a classical element of various milling inserts. Its width should be greater than the feed per revolution. Despite being called flat, the minor edge sometimes has a complex geometry to compensate for the negative effect of wear development. When an insert is mounted on a cutter, the wiper flat sits parallel to the machined surface. Hence, the surface will be formed by the most protruding insert of the cutter. Introducing a wiper flat in an insert design is an effective way to improve the surface finish.  And even today, rough milling inserts may have an integrated wiper. 

ISCAR’s DOVEIQMILL family face mill carries double-sided inserts with a wide wiper flat. These tools are intended for rough and semi-rough milling with a surface roughness that usually features semi-finish to finish passes. The DOVEIQMILL cutters have successfully delivered the hopes of their designers – and the adoption of the cutters in various processes has resulted in the cancelling of finish milling operations. The cutters provide a roughness Ra up to 0.4µm (16µin) when milling steel and cast iron.

Increasing the number of teeth in large-diameter face mills and fine pitch cutters determines the appropriate growth of the integrated wiper width, which has a natural bound due to the design and dimensional limitations. In such cases, a high surface finish can be achieved with the use of a specially designed wiper insert (or two inserts for large-sized tools), whereby the wiper flat is significantly wider than the standard one. This insert is mounted in the same pocket but protrudes several tenths of a millimetre axially relative to the standard insert.

Very good results can be reached by applying adjustable milling cutters that utilise different mechanisms to adjust the position of an insert cutting edge within very strict limits (only several microns). But the beneficial adjustability of cutting tools also has a flip side as well; it is spider work, which takes time. 

A desirable solution looks like a tool that after mounting an insert has no adjusting requirements needed to achieve high surface quality grade. That is why improving accuracy and advanced geometries remain the mainstream aim in updating indexable cutters for finish face milling.

At the same time, cutting tool manufacturers offer unique solutions that attract attention with their originality. An example is ISCAR’s TANGFIN family of milling cutters with tangentially clamped inserts with wide integrated wiper flats. The inserts are positioned in a TANGFIN cutter with a gradual displacement in both radial and axial directions, and therefore, each insert cuts a small section of the machined material providing an extra fine surface finish with roughness Ra up to 0.1μm (4μin). 

For ensuring a high surface quality in milling relatively small faces, mainly bounded by shoulders, ISCAR has developed dedicated exchangeable solid carbide heads in the diameter range of 12 to 50mm for its MULTI-MASTER and T-FACE families. The heads are fully ground and provide high precision, facilitate a sharp cutting edge and enable a greater number of teeth when compared to mills with indexable inserts of the same diameter. In combination, these features guarantee high-performance and high-quality finish milling.

A tendency to decrease machining allowance due to the active introduction of technologies for precise workpiece production and 3D printing makes the issue of obtaining a high surface finish by face milling particularly relevant. Can toolmakers find a prompt, simple, and effective answer to the new needs of manufacturing? 

As well as having concerns over surface finishing, another issue for the modern machine shop is the selection of the right tool for the right application. Like with the surface finish challenge, it can be difficult for manufacturers to determine whether a standard tool or a special tool is preferable. The ideal tool selection is contingent on various factors, such as the nature of the business situation, the manufacturing program, the production type, and sometimes personal preferences. Standard cutting tools, produced by a specific tool manufacturer, offer high versatility and are appropriate for machining a diverse range of parts that come in different shapes.

Furthermore, the tool exhibits excellent performance capabilities when cutting various engineering materials. To ensure seamless production processes, it is crucial to have the cutting tools delivered promptly. This is why standard tools are the foundation of tool stock management on metalworking production floors.

A special cutting tool is designed for specific operations on a particular part, made of a specific material, and used on a machine that requires a specific workholding fixture. This custom-engineered tooling solution aims to provide the best possible performance and outcome. However, there is a downside to this solution as it limits the tool’s versatility, making it less adaptable to different applications. As a result, special tools are primarily used for high-volume mass production, especially in the automotive industry.

Special tools vary in their design complexity. Some are simple modifications of standard tools, such as changes to the corner radius or tool length. These modifications fall under the category of ‘semi-standard’ products, which can be manufactured relatively quickly. The design complexity of a special tool is determined by a pre-design study that assesses the customer’s manufacturing limitations, accompanied by cost calculations and production time. The results of the study determine the limits and cost-effectiveness that correlate to the special tool’s delivery time. However, there are additional ways to reduce the delivery time of special tools, such as using solid tools with exchangeable heads, bodies of indexable cutters, or replaceable inserts. The tool manufacturer’s delivery times and production abilities play a significant role in the final decision on how to proceed.

One alternative to engineered special tools is modular tooling, such as ISCAR’s MULTI-MASTER. It features rotating tools with exchangeable solid carbide heads. This tooling system includes a wide range of tool bodies, adapters, extensions, and reducers that enable the configuration of the required tool for diverse machining operations. 

Additive manufacturing also presents new opportunities for special tool solutions. This technology allows for the quick production of tools with complex profile designs. Although finish cutting and grinding operations are still necessary, the fast manufacturing of pre-shaped products that are very close to a final shape is fascinating. Additionally, 3D printing can be used to fabricate carbide inserts without the need for a die-set, which significantly reduces production time and costs. This process is an excellent way to create insert prototypes during the development stages and produce low-batch special inserts. AM of carbide inserts and heads is gaining momentum and is highly capable of ensuring fast delivery of customised tools and their components.

Hepco moves forward with Mills

In the last four years, HepcoMotion has installed six new Doosan/DN Solutions machine tools from Mills CNC to strengthen the company’s in-house machining capacity.

Mills CNC supplied HepcoMotion, a leading manufacturer of linear motion systems that is part of the Hepco Group of companies with six new Fanuc-controlled CNC machine tools. The machines comprise five DNM VMCs and this includes four DNM 6700 models where two are extra-long bed variants. These are accompanied by a DNM 5700 as well as a VT 1100M VTL with driven tooling.

The machines have been installed at the company’s Headquarters in Tiverton, which has a 4,800sq/m production facility with approximately 40 CNC machine tools organised into discrete production cells for the respective milling, turning and grinding technologies. The Tiverton site also boasts a sizeable assembly operation, a heat treatment facility, a dedicated ring cell and a linear slide processing line. It is here that cutting, straightening, chemical blacking and grinding operations are undertaken.

Taking a closer look at the company, HepcoMotion’s Engineering Manager Mr Ryan Berry says: “We are a vertically-integrated, self-sufficient company. Controlling the methods and means of production in-house helps make us more agile, cost-competitive, productive and better able to meet the needs of our domestic and overseas customers.” 

With its linear and rotary guide systems that feature the company’s innovative V-Guide technology, HepcoMotion is a world leader in linear motion technology that is utilised by specialist machine builders, systems integrators and end-users across a wide range of industry sectors.

As Ryan Berry continues: “We are always looking to improve and regularly monitor and benchmark against KPIs to identify areas within our manufacturing processes that need to be strengthened. When and where issues are identified, we act quickly and decisively to address them – investing in new technology as required.”

To help meet the growing worldwide demand for its linear motion technology solutions, HepcoMotion made its first investment in Doosan machine tools from Mills CNC in 2019. As Ryan adds: “We needed to increase our in-house milling capacity and capabilities, primarily to machine high-accuracy aluminium components used in our linear motion systems. We also needed to upgrade our ring cell where we machine large-diameter circular rings for our PR2 curved rail and track systems. These are made from steel and stainless steel plate and forgings. Although we had not previously invested in Doosan machine tools from Mills CNC, we knew that both the machines and the company had a good reputation in the market. As part of our decision-making process, we approached Mills with our requirements and were introduced to technical, applications and service staff within their organisation as well as having technical presentations on the machine tool solutions recommended. In this instance, a DNM 6700XL for our milling department and a VT 1100M vertical turning lathe for the ring cell.”

The DNM 6700XL is a rigidly built, large-capacity 3-axis VMC equipped with a BT40 spindle that has an 18.5kW 12,000rpm spindle motor. To meet HepcoMotion’s specific production requirements, the machine was supplied with through-spindle-coolant capability, a 4th-axis interface and Renishaw probing systems.

Says Ryan Berry: “The DNM 6700XL has a good-sized worktable with an extended X-axis stroke that enables us to machine large and/or multiple smaller parts in one set-up. The integration of a 4th-axis rotary table has increased our flexibility and, as a consequence improved productivity.”

Such has been the reliability and high performance of its first DNM machine, acquired back in 2019, that the company has subsequently invested in another four DNM machines in the last three years. These include models with 4th/5th-axis units and one with linear scales.

Discussing the VT 1100M large-capacity 32” chuck vertical turning lathe, Ryan continues: “The VT 1100M has helped improve part accuracies and increase our process reliability. The driven tooling capability means we can mill ID and OD features quickly in one set-up without having to transfer parts between machines.”

The six Doosan/DN Solutions’ machines installed at HepcoMotion’s machine shop are in constant use, operating 24/7, machining components in a range of batch sizes from prototype up to 500-off. Mills has also supplied a sister company, Braintree Precision Components (BPC) in Essex, with three turning centres over the last nine years, further cementing its preferred partner status with the group.
