ABSTRACT:
A method and apparatus for finishing a surface of a commutator of a motor, in which a distance between a surface to be finished and a reference position is measured in advance prior to the surface-finishing, and thereafter, turning, cutting or buffing is performed. The data of distance measuring is utilized for the surface-finishing later. Opposite ends of a shaft of the commutator are supported and the supported ends are rotated at uniform speeds. The commutator during the turning is variably controlled in accordance with a turning position.
