[0002] Miniature commutators are key components in miniature DC motors, and their surface finish and precision directly affect the motor's performance and lifespan. Before leaving the factory, miniature commutators require polishing of different parts. Traditional polishing of miniature commutators relies mainly on manual operation, which lacks precise positioning and clamping of the commutator, resulting in low efficiency, poor consistency, and unstable polishing quality. Furthermore, high labor costs make it difficult to meet the demands of large-scale, high-precision production. Therefore, developing a new automated polishing machine for miniature commutators is of great significance. Utility Model Content
