Stainless steel, titanium or hardened steel: materials that are difficult to machine do not allow large cutting depths and can therefore lead to complications in HPC (High Performance Cutting) milling. The large wrap-around not only results in vibrations, but heat and high cutting forces also develop. Although the machining process can be implemented at low cutting speeds, it is clearly inferior to other production processes in terms of economic efficiency.
In order to still be able to machine titanium and co. with a large metal removal rate, HSC milling (high-speed cutting) offers a sensible alternative. HSC milling is characterized by low cutting depths and high feed rates. The cutting forces are thus significantly lower and the heat development is also at a very moderate level. The basic principle of HSC milling is based on generating thin chips in order to increase the tooth feeds.
