传统的硬质合金刀具材料均为WC基，后来出现了TiC基。近年又广泛使用TiCN基硬质合金。TiCN基合金有一定优越性。本文对TiCN基硬质合金刀具的切削性能与机理进行了研究，并对国内外同类产品进行了对比。
Traditional cemented carbide tool materials are WC-based, followed by the emergence of TiC-based. In recent years, extensive use of TiCN-based cemented carbide. TiCN-based alloys have some advantages. In this paper, the cutting performance and mechanism of TiCN-based cemented carbide tools are studied, and the similar products at home and abroad are compared.
