FIELD: manufacture of grinding discs of superhard abrasive materials and designing optimal structure of grinding discs. SUBSTANCE: method comprises steps of using grinding discs with abrasive grains having maximally possible strength; determining wear rate of binder of each grinding disc in zone arranged in front of abrasive grains; selecting as optimal concentration of abrasive grains in grinding disc with minimum wear rate of binder. EFFECT: simplified determination of optimal concentration of abrasive in grinding discs. 2 dwg, 1 tbl
