PURPOSE:To improve efficiency by detecting a pulse of a rotary whetstone and a pulse concerning teeth of a work, and storing the number of the pulses. CONSTITUTION:A pulse generator 42 for generating a pulse in responce to revolutions of a cutting tool is connected to a counter 64 while connected from the counter 64 to a count memory circuit 74. Information of a pulse generated from the pulse generator 42 and that of a pulse detected by rotation of a work 20 are introduced into the count memory circuit 74 via the counter 64 and compared with pulse information already stored. A second rotation driving source is controlled by an output signal of the compared result. In such a way, efficiency and processing accuracy can be improved.
