ABSTRACT:
A grinding tool is provided that is especially designed for the accurate and efficient grinding of overhead camshaft motor valve clearance discs. The tool hereof includes a tool outer casing adapted for retainment in the clamping fixture of a grinding machine, a disc retaining head rotatably carried by the housing, and an axially aligned release rod shiftably carried within the retaining head and housing. In operation, the disc is retained by a lubricated force fit within a retaining head counterbore, and the grinding tool positions the disc in grinding contact with the generally planar grinding surface of a rotatable grinding wheel. The rotational mounting of the retaining head within the tool housing allows for rotation of the disc relative to the grinding wheel surface, thereby enhancing the even grinding of the disc.
