ABSTRACT:
A machine for automatically grinding a helical gear. The machine comprises a first rotational drive source for rotating a grinding wheel, a second rotational drive source for rotating a helical gear in mesh with the grinding wheel, a third rotational drive source for displacing the helical gear and the second rotational drive source in unison. Pulse generators are operatively connected to the first and third rotational drive sources. An output signal from one of the pulse generator is subtracted from an output signal from the other pulse generator to produce differential pulses which serve as drive pulses for the second rotational drive source.
