FIELD: electric tools.
SUBSTANCE: invention is related to the field of abrasive processing and may be used for manufacturing of electroconductive discs for electroerosion abrasive polishing on ceramic binding agent made of powders of natural and synthetic abrasive materials, for instance, diamond, cubic boron nitride, silicon carbide, fused corundum, etc. When abrasive tool is manufactured, preliminarily baked item on ceramic binding is saturated in gas phase by products of carbon-containing gases pyrolysis. Saturation is carried out at temperature of 300-1350°C and pressure of 0.0001-3000 atmospheres with provision of depositing of mentioned products on the pores walls of porous structure of abrasive item, which allows to impart to the latter electric conductivity, which is sufficient for conduction of electroerosion abrasive polishing process.
EFFECT: increase of mechanical strength and chemical resistance of tool.
