FIELD: metallurgy.
SUBSTANCE: disposal graphite press mould is manufactured with through holes, which forms and sizes correspond to lower projection of bit matrix sectors section. During diamonds laying, loading, formation and matrix charge pressing, under graphite press mould placed is a base which upper surface reproduces profile of surface of matrix sectors lower part. At sintering in vacuum furnace the base is removed. Under each bit matrix sector placed are pellets of treated metal or alloy, so that treatment was performed from bottom to top.
EFFECT: providing self-adjusting and homogeneous dosing of treated metal or alloy in all the matrix sectors, matrix uniform density, improving yield ratio, excluding metal lapping on tool housing.
