Abstract
An end face polishing method provides an end face polishing apparatus having a main body, a jig board mounted on the main body and supporting at least one workpiece, a polishing board mounted on the main body for undergoing rotational and revolving movements relative to the main body, and abrasive members each removably connectable to the polishing board for rotational and revolving movements therewith. Each of the abrasive members has an abrasive surface with a hardness that is either higher or lower than the hardness of the abrasive surface of the others of the abrasive members. An end face of a workpiece is successively brought into pressure contact with the abrasive surface of each of the abrasive members in descending order of hardness of the abrasive surfaces while rotating and revolving the polishing board to thereby successively polish the end face of the workpiece.
