1. Chemical polishing

Chemical polishing is mainly used on some small batches of complex parts and products that do not require high brightness. The main advantage of chemical polishing is that it can effectively polish complex parts with high efficiency. After chemical polishing The parts have better anti-corrosion properties, and the use of chemical polishing requires relatively less investment in processing equipment. The disadvantage is that the brightness of the processed parts is not high, and gas is produced during the process, which requires ventilation equipment, and there are certain difficulties in the heating process.

2. Electrochemical polishing

Electrochemical polishing is mainly used in some high-end products and imported and exported products. The advantage is that the processing technology is stable and the operation is simple, and electrochemical polishing can keep the mirror surface of the workpiece shiny for a long time. The disadvantage is that the investment in processing equipment is relatively large, and cooling facilities are required to assist in a large number of operations.

3. Mechanical polishing

Mechanical polishing is currently mainly used for simple parts and small-volume products. The advantage is that it has better flatness after processing, good polishing effect, and high brightness. However, the disadvantage is that it causes serious pollution, is very labor-consuming, and cannot handle complex and complex surfaces. Parts with high process requirements are polished.
