ABSTRACT:
An indexing system for a saw regrinding machine includes a rotary shaft on which a circular saw is mounted and an index stop assembly which stops rotation of the blade to position the teeth thereof for a regrinding operation. The stop includes an index finger interposed into the path of the blade by an air cylinder which is controlled by a timing cam. The air cylinder includes an output piston that pushes a counterweight causing it to rotate about a pin. A finger member is attached to the counterweight and at appropriate times rotates about the pin to intercept a particular saw tooth in a position to permit it to be sharpened by a grinding wheel.
