ABSTRACT:
A top and face grinder for a circular saw blade including an indexing apparatus which interposes a stop into the path of the teeth of the saw blade from a position laterally displaced from the plane of the saw blade. This stops rotation of the blade and permits a grinding operation to take place. At the end of the grinding operation the stop is retracted to permit continued rotation of the saw blade. The grinding stroke position of the grinding wheel is adjusted by rotating a cam which passes through the fulcrum of a rocker arm providing reciprocal motion for the grinding wheel.
