FIELD: machine building.SUBSTANCE: invention relates to abrasive processing and can be used in production of abrasive tools for high-speed grinding. Invention comprises an abrasive body comprising a binder in an amount of not more than about 15 vol% of total body, abrasive particulate material comprising abrasive agglomerates and non-agglomerated abrasive particles and pores constituting at least about 42 vol% of total volume of abrasive body. Ratio of amounts of non-agglomerated abrasive particles in body to agglomerates ranges from 3:1 to about 1:3.EFFECT: improved technical characteristics of bonded abrasive articles, enabling use thereof in operations of high-speed grinding.18 cl, 10 dwg, 2 ex, 5 tbl |
