FIELD: manufacture of abrasive members. SUBSTANCE: abrasive dust is placed between cermet backings and submitted to the effect of high pressure and temperature within the range of thermodynamic stability of abrasive; a mix of synthetic diamond dust with a particle size within 80 to 200 microns and natural diamond dust with a particle size within 10 to 30 microns, their weight ratio being from 20: 1 to 1: 1, is used as abrasive. EFFECT: facilitated procedure. 1 tbl
