TRUING DEVICE AND TRUING METHOD FOR GRINDING WHEEL

摘要

A truing apparatus for a grinding wheel is provided with a correcting tool which is held so as to rotate, and the grinding wheel which is rotating is corrected by the correcting tool. The correcting tool includes a peripheral surface truer having a truer surface formed on its rotating peripheral surface, and an end surface truer having a truer surface formed on its end surface in a direction of a rotation axis thereof. The rotation axis of the correcting tool is arranged substantially perpendicularly to a rotation axis of the grinding wheel so that an end surface of the grinding wheel may be corrected with the peripheral surface truer, and a peripheral surface of the grinding wheel may be corrected with the end surface truer.
