Yamazaki Mazak will be showing its ‘entry level’ machine tools on Stand 350 in Hall 20. Mazak will showcase cost-effective technology such as the CV5-500 5-axis and the 3-axis VCE Series machining centres and the QTE turning centres.
This blend will demonstrate how the quality, technology and productivity is perfect for newcomers and seasoned experts – credit to the user-friendly Mazatrol Smooth CNC system. The CV5-500 entry-level 5-axis machine has been designed to combine high-speed precision machining with ease of operation and its bridge construction with a fully supported trunnion table provides uncompromising rigidity for precision machining.
The trunnion table with roller gear cam on the B/C axes and roller linear guides provide a stable and robust platform and the rolling motion of the cam gear eliminates backlash. The result is an ability to contour or index in 0.0001-degree increments. Offered with a 12,000rpm 18.5kW spindle or with an optional 18,000rpm high-speed spindle, the CV5-500 incorporates a 30-tool magazine with a 1.3 second tool-to-tool ATC and the Mazatrol SmoothX CNC system. With an X, Y and Z-axis stroke of 730 by 450 by 470mm and a BT40/CAT40, the new machine can accommodate a maximum table load of 200kg. The envelope and table capacity give the CV5-500 the ability to produce everything from small to relatively large components.
Complementing the CV5-500 will be the VCE-600 3-axis VMC. Designed and built in the UK, the VCE-600 has an appealing price-point whilst incorporating a variety of new technologies. With a spacious 1.3m by 600mm table and X, Y and Z-axis travel of 1050 by 600 by 600mm, the VCE-600 has a 12,000rpm 18.5kW dual winding spindle with 119.4Nm of torque that provides exceptional power for heavy-duty milling at the low-speed range whilst at high speed, the spindle retains a high-power output. The 7/24 No40 spindle with through coolant is supplied with cutting tools by a quick-change 24 position ATC. As well as a class-leading spindle, the VCE-600 has rigid linear roller guides on all axes that emphasise the ability to perform both heavy-duty and high-speed machining. This is complemented by direct drive servo motors on all axes and fully ground pre-tensioned ball screws that deliver precision and repeatability.
The new Mazatrol SmoothEz CNC control system on the VCE-600 with its intuitive 15inch touch screen display can offer ‘Ez Operation’ with its ability to be operated like a smartphone or tablet can be customised with the positioning of data to suit the user. For ‘Ez Setup’, the SmoothEz enables all manufacturing data, such as programs, fixture setup, machine models, tooling data and coordinate systems to be synchronised by Smooth Project Manager to SmoothCAM Ai. Having all this in an entry-level machine defines why Mazak leads the industry. Appearing alongside the machining centres will be the QTE Series of turning centre that ranges from the extremely compact QTE100SG that has a maximum machining capacity of 290mm diameter through to the QTE300SG that offers a diameter up to 350mm with a workpiece length up to 1063.5mm. The variant on show at MACH will be the QTE200SG that can accommodate parts up to 290mm diameter with a maximum workpiece length of 285/520mm. The QTE200SG is a highly compact workhorse that provides productive turning capability.
The QTE200SG is driven by an integral 5000rpm high-performance 15kW stepless spindle motor that requires no transmission via belts, pulleys or gears. This minimises vibration during high-speed cutting to improve tool life whilst delivering exceptional power throughout the speed range. The QTE200SG has a servo-driven 12-position tool turret with a capacity for 25mm diameter tool shanks that minimises non-cutting time with its non-lifting indexing. Optionally, customers can select an 8 or 24 tool turret as well as milling spindles that can be found on the M, MY, MS and MSY variants.
Separating the QTE200SG from other machines in its class is the Mazatrol SmoothEz (Easy) CNC interface. Similar to other Smooth controls in the Mazak portfolio, the SmoothEz defines ease of use and productive solutions with fast set-up times. For ‘Ez set-up’ the data on the machine can be synchronised with a PC in the office via Smooth Project Manager, creating virtual machines to duplicate factory floor production. As an entry-level machine, the Quick Mazatrol provides ‘Ez operation’ with its ability to quickly and easily create, check and edit programmes by displaying the 3D model of the workpiece on the customisable touch-screen display.
