ABSTRACT:
A synchronous operation control apparatus for rotating a grinding wheel and a gear to be ground thereby in synchronism to grind teeth of the gear to a nicety. A pulse generator is connected to a rotational drive source for rotating the grinding wheel, and a counter is connected to an output terminal of the pulse generator. A division error is calculated from the number of teeth of the grinding wheel and the number of teeth of the gear which have been supplied in advance, to produce data for correcting the division error. A rotational drive source for rotating the gear is energized by frequency-divided pulses issued from the counter with a count as corrected by the data.
