Abstract
A method and an apparatus for providing an optical fiber connector or similar workpiece formed of, e.g., glass, ceramic or plastic with a mirror-finished convex tip efficiently is disclosed. While a film-like abrasive tool is conveyed in contact with the wall of a groove formed in a stage, the workpiece is caused to rotate about its axis (and to move in a reciprocating motion). By the resulting grinding operation, the sectional shape (arcuate) of the abrasive tool contacting the wall of the groove is transferred to the end of the workpiece. As a result, the end of the workpiece is provided with a convex tip. The abrasive tool is replaced with an abrasive tool for finishing, as needed.
