摘要 |
Hard composite material for tools, comprising a substrate of CBN sintered body containing more than 20 % by volume of cubic boron nitride or diamond sintered body containing more than 40 % by volume of diamond. The substrate has at least one layer of hard heat-resisting film consisting mainly of Ti, Al and at least one element selected from a group comprising C, N and O on a portion or portions of said substrate where cutting participate. Improved in strength of base material, wear-resistance and oxidation-resistance, less reactive with iron and showing longer tool life comparing to known cutting tools and usable in wider applications such as hardened steel, cast ion and simultaneous cutting of cast ion and aluminum alloy. |
