FIELD: machine building.
SUBSTANCE: grinding-abrasive device contains grinding grains inserted in each other as per a "nested doll" principle, and a composition for their securing to a rigid or flexible base. The grinding grains have a cone shape tapering towards the base, and in clearances between them to the height below the height of the grains the said composition is located ensuring the grains securing with each other. The free space from the top of the composition to the top of the grinding grains is filled with a coolant-cutting fluid ensuring the device cooling during treatment.
EFFECT: increased stability of the grinder and quality of the treated surfaces.
