Polishing method of polishing plate and diamond material for diamond polishing material

摘要

PROBLEM TO BE SOLVED: To provide a polishing machine for polishing a diamond material, which can polish the diamond material at high speed with high surface precision.;SOLUTION: In the polishing machine for polishing a diamond material, at least a polishing surface of the polishing machine is formed of diamond particles and a binder. The diamond particles adjacent to each other are connected to each other to form a continuous structure, and the binder is formed of a diamond sintered body including at least one kind of element selected from a group of Ni, Co and Fe, at least one kind of element selected from a group of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W, and a carbide of at least one kind of element selected from the group of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and W.;COPYRIGHT: (C)2013,JPO&INPIT
