[0002] Metal fittings play an important role in industrial production, and their quality directly affects the performance and service life of products. In order to improve the surface finish and corrosion resistance of these metal fittings, polishing treatment is necessary.

[0003] Metal fitting polishing machine is specially used for fine polishing of metal surface, usually through clamp to fix fitting on polishing table, and through left and right or front and back movement of clamp to adjust the position of fitting. However, for circular metal fittings, especially the polishing of the circumferential outer wall, the existing equipment has obvious deficiencies.

[0004] Due to the special structure of circular metal fittings, it is difficult to fully cover the outer wall by linear movement of the clamp, resulting in the following problems:
