Abstract

Procedure for manufacturing a grinding wheel or a rotating abrasive body, characterized in that a wheel provided with a central hole based on abrasive grain, binder and, preferably, active and inactive filler material, is placed in said hole, after the hardening of the binder, a rigid mold ring whose outer diameter is less than the diameter of the hole in the grinding wheel, a synthetic foam material, for example polyurethane foam, is injected into the space between the mold ring and the grinding wheel, it lets expand and cure said foam material, to form the hub of the grinding wheel, and the mold ring is removed from the hole in the grinding wheel.
