The improved AlCr coating system can be used for a wide range of machining processes during which high or even extreme temperatures occur locally. The layer structure which was optimised through the use of HIPIES technology thus allows for increased coating adhesion on tools that are subject to extreme mechanical and thermal stress as well as outstanding performance parameters. Modifications to its internal tension yield a more stable operating behaviour while the coating is also extremely wear resistant. This makes the ALLTRON the “jack of all trades” – a perfect PVD coating system for the fields of high-performance machining, milling, drilling and cutting, metal forming and punching as well as dry machining.
