Surface polishing process: Surface polishing is commonly used in daily necessities. It involves removing burrs from metal products. For example, when we produce a comb made by stamping metal parts, the edges of the stamped comb are very sharp. We need to polish these sharp edges into smooth surfaces so that they will not cause harm to the human body during use.
1. Spray Painting Processing: Hardware factories use spray painting processing when producing large hardware products. Spray painting prevents hardware parts from rusting, such as daily necessities, electrical housings, handicrafts, etc.
2. Electroplating: Electroplating is also one of the most common hardware processing techniques. By using modern technology to electroplate the surface of hardware parts, it ensures that the product does not mold or rust after long-term use. Common electroplated items include screws, stamped parts, battery sheets, vehicle parts, small accessories, and so on.

Polishing is used to smooth these sharp edges so that they do not cause harm to the human body during use.
Turning the outer cylindrical surface is the basic method for processing outer cylindrical surfaces in hardware processing, using a lathe. In general machinery factories, lathes account for about 40% of the total machine tools. Turning is the main method for rough and semi-finish machining of outer cylindrical surfaces of various materials and is the final finishing method for materials that are not suitable for grinding.
For single-piece or small batch production, turning the outer cylindrical surface is generally done on an ordinary lathe. For mass production, multi-tool semi-automatic or automatic lathes are widely used. Large disc-shaped parts should be processed on vertical lathes. Large long shaft parts need to be processed on heavy-duty horizontal lathes.
