    Influence of Carbide Volume and Size on Machinability of Cold Working Die Steels  [in Japanese]

    Shimizu Takayuki , Ozaki Kozo

    … The influence of carbide volume and size on endmilling machinability of cold working die steels have been investigated. … The volume of large primary carbide (M7C3) and small spheroidal carbide (M23C6,M7C3 and M6C) is controlled by carbon and chromium content. … (1)Tool life of endmilling is prolonged by decreasing carbide volume. …
