Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a polishing and grinding device for metal parts. Background Art

[0002] Polishing is a processing method that reduces the surface roughness of a workpiece through mechanical, chemical or electrochemical effects to obtain a bright and smooth surface. During the polishing process, finer abrasives or grinding tools are used to rub against the surface of the object, so that the uneven parts are gradually smoothed, thereby improving the flatness of the surface.
