Hitachi Tools (Headquarters: Tokyo) has expanded its product lineup of the "Epoch TH Power Mill" series of end mills for high-hardness steel processing. This time, 18 types of "short edge models" with a blade length of 4.5 to 30.0 mm, 9 types of "mid blade models" of 15.0 to 55.0 mm, six types of "long blade models" of 25.0 to 75.0 mm, and 35 kinds of fillet radii have been added. It is a "rounded corner" of 0.2 to 3.0. Together with the "standard model" with a blade length of 8.0 to 22.0 mm, the series has a total of 86 types.
The Epoch TH Power Mill series improves the rigidity and chip discharge by working on the shape, and at the same time improves the wear resistance and oxidation resistance by coating a TiSiN-based protective film composed of nanocrystals. The initial oxidation temperature was 1100 ° C and the protective film hardness was 3600 HV. Suitable for roughing, groove processing and final processing of high hardness steel. It is also suitable for dry cutting due to less heat generation during cutting.
