IMPROVED THROW-AWAY ADAPTORS FOR GRINDING WHEELS ABSTRACT An improved throw-away, or single use, adaptor par- ticularly useful with depressed center grinding wheels is described. The adaptor comprises a hollow mandrel having an internal threaded portion for attaching the adaptor to the shaft of a grinding machine. The hollow mandrel has a saucer-shaped disc portion extending axially from the outer portion of the mandrel. The saucer-shaped disc portion has a concave surface and a convex surface. The concave portion is equipped with a plurality of internal rib members and has a flange around the periphery thereof to contact the side of a grinding wheel. The flange portion has a plurality of protrusions, or bosses, thereon adapted to be received in corresponding orifices in the grinding wheel. In operation, as the grinding wheel contacts a work piece, the torque, or stress, is directly imparted to the adaptor, as the adaptor is threadably attached to the shaft of the grinding wheel. The torque, in turn, is distributed in an equitable manner, through the combination of rib members and protrusions in the adaptor to the grinding wheel.
