ABSTRACT:
Resinoid-bonded grinding tools are prepared by applying a liquid thermosetting resin to the circumferential surface of a disc-like base member and then after coating metal-coated abrasive grains with a liquid thermosetting resin, mixing the coated grains with a powdered thermosetting resin. The mixture of the coated grains and the powdered thermosetting resin is press-formed upon the surface of the base member and then thermally set by heating.
