FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to fabrication of tools with metal binders containing the diamond powders as cutting grains. Claimed process comprises making the briquette from the diamond-bearing mix and impregnating said briquette with impregnation material. Note here that the mix composition includes extra alloying metal powders which, when impregnated, tend to form, with the impregnating material, the adhesive-active alloys relative to the diamond powder. Note here that said alloying metal powders used feature the grain size of 4-20 mcm.
EFFECT: higher wear resistance and lower labour input in tool fabrication.
