ABSTRACT:
A method of making grinding wheel mounts by molding a central hub onto a thermoset plastic abrasive disc is provided. An aromatic polycarbonate thermoplastic resin is molded to form a hub on a cured thermoset plastic abrasive disc. It is believed that the polycarbonate forms both a mechanical and chemical bond with the thermoset plastic to provide an efficient method of producing grinding wheels.
