FIELD: mechanical engineering. SUBSTANCE: abrasive article is in the form of sheet. Located on its working surface is multiplicity of abrasive composite pieces which are precision in shape, but not all precision shapes are similar. Described in invention are method and working tool for manufacture of abrasive article. Abrasive tool is intended for finishing treatment of products with high productive capacity and relatively high cleanliness of treated surface without leaving any marks or scratches on treated surface. Due to different dimensions of adjacent composite pieces of precision shape, stopped and/or prevented is occurrence of vibration resonance. This adds to higher productive capacity and to higher cleanliness of worked surface. EFFECT: higher efficiency. 19 cl, 8 dwg, 2 ex, 1 tbl
