ABSTRACT:
A grinding wheel has a series of deep and narrow circumferential grooves between circular grinding sections having radially convex surfaces for forming serrations in a knife edge. The grooves are filled with a non-abrasive substance to strengthen the wheel and prevent a build-up of serrating grinding off-fall as well as providing an indication by sound and feel when grinding of the serrations in a knife edge is completed. One embodiment has a plurality of abrasive discs mounted on a holder with smaller diameter non-abrasive discs between each of the abrasive discs, to form grooves therebetween. The holder forms a hub for mounting the assembled wheel on a spindle. A second embodiment has a vitrified abrasive which is pressed to form a blank with a cylindrical outer surface and a hub portion for receiving a spindle. The blank is fired to a relatively low temperature so that it may be mounted on a spindle as narrow annular grooves are cut through its cylindrical surface, and the outer faces of the abrasive sections between the grooves are dressed to a convex radius half the thickness of the abrasive sections. The grooves are then filled with a non-abrasive material to a diameter less than that of the abrasive sections and the wheel is fired to a relatively high temperature to give the abrasive sections desired hardness.
