ABSTRACT:
A grinding wheel mounting in which the wheel has a mounting hole of polygonal form into which is removably and coaxially inserted a corresponding polygonal shaped portion of an elastically deformable plastic body engaging the internal polygonal surfaces of the wheel. The body has a flange at one end in engagement with one side of the wheel and screw threads at its opposite end threadedly engaging with a slight interference fit, a threaded end portion of a grinding wheel spindle having an annular surface in clamping engagement with an opposite side of the grinding wheel. Upon screw threading the body together with the grinding wheel to the spindle, the grinding wheel is axially clamped beteen the flange on the body and the annular surface on the spindle and the body is slightly deformed radially by the interfering threaded portions thus eliminating axial and radial play, friction, slippage, wear and abrasion of the spindle threads.
