DOUBLE END FACE TRUING DEVICE, DOUBLE END FACE TRUING TOOL, AND DOUBLE END FACE TRUING METHOD

摘要

A double end face truing device, wherein first and second cylindrical base bodies are axially projectedly formed on both side faces of the disk-like base of a double end face truing tool, and first and second abrasive grain layers to which a large number of diamond abrasive grains are adhered with a binder are formed on the outer peripheral surface of the first base body to form first and second end face correction parts. The rotating axis of the double end face truing tool is tilted by a specified angle relative to the rotating axis of a grinding wheel in an approximately same plane. Since the double end face truing tool is moved to the rotating axis of the grinding wheel, the first and second abrasive grain layers trues up, in the state of being supported prior to the first and second base bodies, the both side end grinding faces of the grinding wheel to sharp grinding faces having appropriate irregularities under the approximately same conditions. Thus, the both side end grinding faces of the grinding wheel can be trued up to the sharp grinding faces having appropriate irregularities under the approximately same conditions.
