For Sanitary Valve, there are three commonly used polishing methods: mechanical polishing, chemical polishing, and electrochemical polishing. Each of these three methods has its own advantages and disadvantages.

1. Mechanical polishing.

Its advantages are good flatness and high brightness of the parts after processing. Its disadvantages are high labor intensity, serious pollution, and complex parts cannot be processed, and their gloss cannot be consistent, the gloss is not maintained for a long time, and they become stuffy and rusty. It is more suitable for processing simple parts, medium and small products.

2. Chemical polishing.

Its advantages are low investment in processing equipment, complex parts can be polished, fast speed, high efficiency, and good corrosion resistance. Its disadvantages are poor brightness, gas overflow, ventilation equipment is required, and heating is difficult. It is suitable for processing small batches of complex parts and products with low brightness requirements for small parts.

3. Electrochemical polishing

Its advantages are long-term mirror gloss retention, stable process, less pollution, low cost, and good corrosion resistance. Its disadvantages are high pollution resistance, large one-time investment in processing equipment, tooling and auxiliary electrodes for complex parts, and cooling facilities are required for mass production. It is suitable for mass production and is mainly used in high-end products, export products, and products with tolerances. Its processing technology is stable and the operation is simple.
