Guhring Speeds Milling Innovations to MACH 2020
At the MACH exhibition, Birmingham based Guhring will be demonstrating its milling expertise with the arrival of a multitude of next generation cutting tool innovations. In Hall 17 on Stand 400, the globally recognised manufacturer will be introducing its new RF100 5-Speed and RF100 7-Speed solid carbide end mills alongside a number of established industry leading milling tools.
Developed for the machining of very tough materials, the new RF100 5-Speed and RF100 7-Speed solid carbide end mills take cutting speeds and process reliability to a new level. The increased tooth number of the five-fluted 5-Speed and seven-fluted 7-Speed generate high metal removal rates with stable process reliability, even when processing the most difficult-to-machine materials. Providing high-performance roughing even at high cutting depths, the two new ranges maximise feed rate parameters during large metal removal rates. As part of the highly dynamic Guhring Trochoidal Cutting (GTC) series, the new RF100 5-Speed and RF100 7-Speed are perfect for machining tough stainless steels, special alloys and a wide variety of steel and cast-iron grades.
At limited machine speeds or cutting speeds limited by the material, the RF 100 5 and 7-Speed ensure high feed rates and long tool life thanks to the increased number of teeth. The new arrivals are particularly suitable for difficult-to-machine materials under stable conditions and they can conduct trochoidal cutting at an ae rate of up to 10%.
The optimal cutting conditions for the RF 100 5-Speed is applications on all tough materials up to 1200N/mm² and where a ramping angle of up to 10° is required. The new innovation is also perfect for slotting with cutting depths up to 1XD and helical milling. Whilst the RF 100 7-Speed is also the perfect choice for tough materials up to 1400N/mm², the seven fluted variant is also ideal for helical milling at in-feeds of up to 0.05XD ap per cycle. From a dimension perspective, the new RF 100 5 and 7 Speed are available with cutting diameters of 6, 8, 10, 12, 16 and 20mm with a necked diameter that permits cutting depths from 20 to over 60mm depending upon diameter selected.
Also, on show from the Guhring milling stable at MACH will be the new Ratio® line of roughing end mills. With flat crested geometry and an optimised roughing profile that demonstrates 60% longer service life, the new Ratio® high-performance roughing cutter has several geometry adjustments aimed at providing performance far beyond competitor products. The Ratio® drastically increases material removal rates with its asymmetrical cutting flutes that reduce cutting pressure compared to smooth cutters. This soft cutting action allows the Ratio® to perform exceptionally well on low powered machine tools or machines with unstable fixturing. Large flutes ensure optimum chip removal and high process reliability.
Alongside the Ratio® will be the extremely popular RF100 Diver series of end mills that have been identified as an industry benchmark in terms of performance. With optimised internal cooling channels and continued program expansions that support ramp drilling, grooving, rough finishing and finish milling, the RF100 Diver has been designed for customers with constantly changing requirements. This means it is suitable for five operations with just one tool. The front and peripheral geometry of the RF100 Diver has been FEM optimised to improve coolant delivery and chip removal efficiency. This optimisation delivers 40% longer tool life on sticky materials and stainless and heat resistant materials.
As well as demonstrating an extensive range of innovative solid carbide tooling solutions, Guhring engineers will be on hand at MACH to discuss the remarkable scope of the 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 100m2 stand at MACH, Guhring will also be demonstrating its extensive PCD cutting tool portfolio. In 2019, Guhring published a new ‘High Performance Tools for Machining Modern Composite Materials’ brochure and products from this 24-page publication will also be on show at MACH. The extensive range of PCD milling tools include 2, 3 and 4 cutting edge PCD slot drills and end mills with through-coolant that are all available with a wide variety of shank forms and tolerances, surface finishes and coatings, helix and rake angles and cutting edges.
