Abstract

PURPOSE:To hold high accuracy of finish despite wearing of a grindstone, by changing an abrasive condition of abrasive time or the like in accordance with a quantity of polished works counted by a counting means. CONSTITUTION:When the polishing program for a polished work is finished, an end signal of one pulse is generated from a signal line 20a, and a counter 21 operates decrement while a counter 22' operates increment. Here the counter 21 gradually increases an abrasive time through an NC control main unit 20 as its counting number, that is, a number of polished works increases. While the counter 22', if its counting number reaches a prescribed number, operates a stopper moving motor 30 through circuits 24, 25.... This motor 30 is actuated cooperatively with the NC control main unit to correct the protrusive amount of a grindstone.
