Workpieces such as wheel rims, hubs, bearing housing seats, flat plates, and shells, which are cut by casting and machining, are usually made of high-quality steel or aluminum alloy and the like. Their surfaces will have casting lines, machining tool marks and angular burrs. Before use, the surfaces of these workpieces need to be polished, ground and deburred. The conventional process is to use equipment such as scrapers, brushes, cloth wheels, and sand belts for polishing and deburring operations. However, these equipment have low efficiency, poor polishing effect, and require manual polishing and grinding. The polishing dust is large, the efficiency is low, the dust pollution is serious, and the danger coefficient is high, and the environmental pollution is large. To solve this deficiency, someone has invented a polishing and deburring machine using polishing liquid and zirconia balls as the medium in the market.
