JINZHU Metal finishing machines are specialized automated or semi-automated industrial equipment designed for processing the surfaces of various metal workpieces. Their core function lies in efficiently and precisely enhancing the smoothness, flatness, and luster of metal surfaces, as well as removing surface defects such as scratches, oxide layers, burrs, and weld marks. 
By applying mechanical friction (such as using polishing wheels, abrasive belts), chemical action (chemical polishing), or electrochemical principles (electrolytic polishing), polishing machines can significantly enhance the aesthetic appearance and tactile comfort of metal products, as well as improve their corrosion resistance, wear resistance, and adhesion for subsequent treatments (such as electroplating and spraying). 
Modern sheet metal finishing machines are widely used in various manufacturing fields such as automotive manufacturing (wheels, exhaust pipes, decorative parts), hardware tools, kitchen and bathroom appliances, medical devices, electronic components, aerospace parts, building hardware, and various metal handicrafts. With a high degree of automation, they can effectively replace the heavy manual polishing work, significantly improving production efficiency, ensuring consistent processing quality, and at the same time reducing labor costs and improving the working environment. They are indispensable key equipment in modern precision manufacturing and surface treatment processes.
