摘要

A diamond cutting tool has a tool substrate (21) and a cutting edge member (22). The cutting edge member (22) is formed of a material having a three-layer structure or a diamond composite material. When the material having a three-layer structure is employed, the cutting edge member (22) is formed by a vapor-deposited diamond layer (11) defining a rake face, a layer (12) of a composite material of vapor-deposited diamond and a metal or ceramics, and a layer (13) of the metal or ceramics. The metal is prepared from Mo, W, Cr, V, Nb, Ta, Co, Ni or Fe, while the ceramics is prepared from cBN, SiC, Si3N4, WC, TiC, TaC, NbC, Cr3C2, Mo2C, VC, TiN or BN. The cutting edge member (22) is brazed to the tool substrate (21) through the layer (13). When the diamond composite material is employed, on the other hand, the cutting edge member (22) is formed of a composite material of particles or fibers of AlN, cBN or SiC and vapor-deposited diamond. The diamond cutting tool is excellent in heat resistance and durability. IMAGE
