PURPOSE: To continuously apply uniform polishing to even a wide belt plate having a large area for a short time by installing a nozzle for continuously supplying electrolyte between an electrode and, a polishing head and the belt plate which make the electrode contact with the polished face of abrasive, and arranging a revolution shaft different from a rotation shaft at the polishing head.
CONSTITUTION: Grinding oil such as, e.g. water soluble cutting oil, etc is supplied onto a belt plate from a nozzle 10. For example, one of grindstones 5A is rotated clockwise and the other 5B is counterclockwise by means of drive motors 8A, 8B. Moreover, a revolution shaft P is provided at the center of a frame 6, a drive motor 8C is connected to this shaft P to be intended to be rotated thereby, and Revolution movement round the shaft P in addition to rotation is applied to the grindstones to perform uniform polishing.
