FIELD: machine building.
SUBSTANCE: building-up welding of the hard alloy layer on back surfaces of axial cutting tools using the method of electrospark alloying is performed, which comprises the creation of carbide titanium or tungsten layer, or titanium boride or tungsten with cobalt or nickel binder with the width 80-90 mcm. The sharpening of back surfaces of the tool is performed with the rough tolerance for processing 20-30 mcm and the roughness Ra 0.8 mcm and additionally using the method of finishing plasma hardening a diamond-like silicon oxicarbonitrite-based coating with the width 1.5-2 mcm and with the hardness 53-54 GPa is applied.
EFFECT: increase of tool resistance and service life.
