ABSTRACT:
Valve seat grinding apparatus having a rotatable drive wheel of disk shape, a plurality of independently rotatable satellite wheels carried about the drive wheel with the respective radial planes of satellite wheels being disposed at a selected included angle with respect to the axis of drive wheel and disposed at a selected radial distance away from the axis of drive wheel. A plurality of slide blocks intermediately connect the drive wheel with satellite wheels. The selected included angle is selected in a range including 90 degrees. The drive wheel is provided of a shape, material and thickness to resist any deflection which would change selected included angle by forces within the range of operational forces applied through the drive wheel to satellite wheels.
