FIELD: grinding of different materials by means of grinding discs of superhard abrasives, namely designing optimal structure of grinding discs and selecting optimal grinding modes. SUBSTANCE: method comprises steps of using grinding disc including grains of superhard material and binder whose wear in zones arranged in front of grains of superhard abrasive material exceeds wear of those grains and causes loss of their stability. Wear of grinding disc caused by stability loss exceeds wear of grinding disc caused by grain rupture. EFFECT: enhanced efficiency of grinding process. 2 dwg, 1 tbl, 1 ex
