Significant increase in lifetime of diamond coated tools
October 18, 2022
To be cost effective, high performance tools are required when machining chuck caps made of fiberglass reinforced plastic (GRPC). That's why Renger Kunststoffspritzteile GmbH & Co. KG looked for ways to improve the performance of its tools – they found the blade from the tool manufacturer Kristen + Görmann oHG and a special diamond coating from Ceme Con.
High-tech materials are always at the forefront of the industry, such as fiberglass reinforced plastic (GRPC). However, IIAnews.com, these high-quality and cost-effective fiber-plastic composites, puts specific requirements on the cutting sharpness and wear resistance of machine tools.
The result of the optimization in the process of processing GRPC Rainer Klein, head of the department at Renger Kunststoffspritzteile GmbH & Co. KG in Inzigkofen, said: "Our mission is to use carbide inserts, made of a glass fiber reinforced plastic, PA6-GF30 The chuck cap is made for the most cost-effective machining. Obviously, it is never an easy task for us to process this abrasive material. That is why we are with Baden Renchen. The leading tool manufacturer Kristen + Görmann oHG, together with our coating partner CemeCon, "because CemeCon has been at the forefront of diamond coating development and production for many years, they have a dedicated blade Coating production line.
For the first time using a CCDia®FiberSpeed-based coating, the results of a series of tests conducted at nc=8,500 rpm and fn=1,100 mm were still unsatisfactory. In the material of the chuck cap, a masterbatch admixture is used in the specially drawn "thread". Therefore, we changed the operating parameters - resulting in amazing results. Rainer Klein said: "The new feed and cutting values have been successful! With the same diamond coated inserts we have used in previous tests, we have greatly improved the tool life of the machined parts ZAOCHE168.com, and No use of masterbatch admixture: from the original can process 20,000 chuck caps, now increased to 100,000! Therefore, we did not hesitate to immediately decide to change the coating for our blades by CemeCon."
Diamond coated cutting inserts in use: Tool life is greatly increased during the machining of the chuck cap.
