Title: Abrasive member of bonded aggregates in an elastomeric matrix

Abstract: Abrasive grains rigidly bonded to each other form aggregates which are dispersed in a resilient matrix of an abrasive wheel so that the aggregates do not significantly interfere with each other's individual movement under grinding stresses against the resilient restraint of the matrix. The wheels remove metal from a workpiece much faster and lose less abrasive material than corresponding wheels in which the same abrasive particles are individually embedded in the same matrix.
