DIAMOND GRINDING MATERIAL FOR METAL BOND GRINDING STONE

摘要

PURPOSE:To improve a holding force generated by means of the metal bond of grinding grains and to improve grinding characteristics, by a method wherein a diamondlike rigid carbon material layer is formed on a diamond grinding grain surface. CONSTITUTION:A diamondlike rigid carbon material layer is formed in a film thickness of approximate 2-5mum on a diamond grinding grain surface to provide a desired diamond grinding material for a metal bond grinding stone. By means of a diamond grinding material by which the carbon material layer is formed, adhesion between diamond grinding grains and a metal bond can be improved, and the frequency of peeling of the diamond grinding material during a grinding work can be decreased. Since a diamondlike carbon material layer itself is actioned as 8 grinding material, the grinding power of a metal bond grinding stone formed by a diamond grinding stone can be improved.
