Abstract:
A polishing method and a polishing film are provided for automatically performing multi-stage batch polishing on an end surface of a workpiece. An end surface of a workpiece and a polishing plate are moved relative to each other while bringing the end surface of the workpiece into contact with a polishing film of the polishing plate. The end surface is moved in a circular motion with a diameter 2 R relative to the polishing film; the center of the circular motion is moved linearly by a distance S on the polishing film; the polishing film is provided with first, second, and third polishing surfaces; and the polishing film is further provided with cleaning surfaces between the polishing surfaces so that the range of the distance S in which one rotation in the circular motion crosses over different polishing surfaces is reduced, or does not cross over different polishing surfaces.
