Abstract:
An ELID centerless grinding apparatus comprising: a blade for horizontally supporting a rotator workpiece and having a slant surface inclined outwards and downwards; and a regulating wheel driven to rotate around a horizontal shaft center, the apparatus performing ELID grinding of a workpiece outer surface by using a conductive grinding wheel,an outer peripheral portion of the regulating wheel including a conductive elastic member and abrasion resisting particles held in the conductive elastic member, the apparatus further comprising: an electrolytic electrode provided in close vicinity to an outer peripheral surface of the regulating wheel; and an electrolytic power supply for applying an electrolytic voltage between the electrolytic electrode and the regulating wheel, thereby, a conductive electrolytic fluid being caused to flow between the electrolytic electrode and the regulating wheel, the conductive elastic member being removed by the electrolytic dressing to cause the abrasion resisting particles to project while the abrasion resisting particles being brought into contact with the outer peripheral surface of the workpiece to rotate around its shaft center.
