Abstract

PURPOSE: To provide a roundness exactly at a polishing device for a cylindrical commutator for a miniature DC motor by rotating a rotor upon depression of a polishing tape to the commutator of the rotor and sequentially feeding the polishing tape at low speed while reciprocating the tape laterally to the left and right to thereby precisely polish the surface of the commutator.
CONSTITUTION: A rotor 1 is rotatably carried on a pair of V-shaped blocks 4, and an endless belt 11 is pressed from above to thereby rotate a rotor 1 and a commu- tator 2. A polishing tape 19 is introduced through a guide 21 under pressure downwardly to the commutator 2, sequentially fed at low speed by feed rollers 24, and reciprocated axially of the commutator 2 via a drive unit and eccentric rollers separately provided. Thus, it can polish precisely the surface of the commutator 2 and improve the roundness of the commutator 2.
