Abstract

PURPOSE: To effectively prevent a work from bending by presseing a work rest against a work appropriately in accordance with pressing force of a grindstone.
CONSTITUTION: A work rest 7 is provided with a supporting body 8 which is capable of shifting freely in the direction perpendicularly to the pressing direction and of supporing fixedly in the pressing direction. Pressure of 2 pressure chambers, located in the aforementioned pressing direction of a static pressure bearing which supports with its shaft a chuck holding a work, is detected by a pressure detecter. Control signals with polarity and magnitude corresponding to deviation of these detected signals are issued as outputs from an amplifier. On the basis of these control signals and by driving the aforementioned supporting body 8 with cylinders 17 and 19, the work rest 7 is shifted so that the aforementioned deviation becomes zero. And by applying to V-shape pressing section of the work rest 7 an appropriate pressure according to the pressing force of a grindstone in operation, a work being ground is prevented from bending. In this manner, a work can be ground with high accuracy.
