(57) A method of manufacturing an abrasive member (10a, 10), in particular having the general shape of a disc such as a cutting or grinding disc, comprises
- arranging a reinforcing insert or reinforcing member (24, 13) into a mold between a layer of curable abrasive resin compound, in particular a layer of curable abrasive granulate, a backing member (16) such that at least a section of the reinforcing insert or reinforcing member (24, 13) is in direct physical contact with the curable abrasive resin compound, the reinforcing insert or reinforcing member (24, 13) is at least partially covered by the backing member (16) and at least a section of the backing member (16) is in direct physical contact with the curable abrasive resin compound;
- bonding the reinforcing insert or reinforcing member (24, 13) and the backing member (16) by curing the curable abrasive resin compound, wherein the cured abrasive resin compound forms an abrasive layer (12) of the abrasive member (10).
