FIELD: process engineering.
SUBSTANCE: invention relates to abrasive tool. Proposed material with binder shaped to abrasive wheel comprises ceramic shaped abrasive particles retained by binder. Every said ceramic particle is confined by polygonal base, polygonal vertex and multiple faces connecting said base and said vertex. Note here that adjacent faces are connected by appropriate ribs with mean radius of curvature smaller than 50 mcm.
EFFECT: lower working temperature, hence ruled out thermal damages.
