[0002] Metal strip polishing equipment is a specialized industrial machine used for precision polishing of metal strip surfaces. Its main function is to remove oxide layers, burrs, scratches, oil stains, and other defects from the metal strip surface using physical or chemical methods, thereby obtaining a smooth, flat surface with high reflectivity or a specific roughness to meet the requirements of subsequent processing or direct application. This type of equipment is widely used for continuous polishing of metal strips such as stainless steel, copper, aluminum, titanium, and alloy steel, playing an irreplaceable role, especially in industries such as precision electronics, automobile manufacturing, home appliance decoration, building decoration, food machinery, and medical devices.
