Abstract

PURPOSE: To achieve cylindrical grinding control with high accuracy by making a contactor contact a work on the other side of the side contacting a grindstone, detecting location of the contactor while making correction of bend of the work and finishing the dfiameter according to the thus detected value.
CONSTITUTION: When a target value is set to a radius setting device 26, a signal from a differential amplifier 27 presses a grindstone 1 against a work 6 to start grinding. At this time, as a bend is caused to the work 6, pressure detectors 12 and 13 detect different values, and an output of the difference of voltage is made by a differential amplifier 6. Similarly, pressure detectors 14 and 15 also detect different values, and an output of the difference of voltage is made by a differential amplifier 17. An addition amplifier 18 adds the aforementioned signal to a serbo valve 22 to shift a piston 21 a for correction of bend. And then, the grindstone 1 is pressed against the work 6 to resume grinding, and when the grinding reached the target value, a sliding plate 3 is stopped to end grinding.
