Three methods of stainless steel polishing

For stainless steel parts, the commonly used polishing methods include mechanical polishing, chemical polishing, and electrochemical polishing. Each of these three methods has its own advantages and disadvantages.
1. Mechanical polishing:

The advantage is that the processed parts have good leveling and high brightness. Its disadvantages are high labor intensity, serious pollution, and the complicated parts cannot be processed, and its gloss cannot be consistent, the gloss retention time is not long, and it becomes stuffy and rusty. More suitable for processing simple parts, medium and small products.

2. Chemical polishing:

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

3. Electrochemical polishing:

The advantages are that the mirror gloss remains long, the process is stable, the pollution is less, the cost is low, and the corrosion resistance is good. The disadvantages are high pollution prevention, large one-time investment in processing equipment, tooling and auxiliary electrodes for complex parts, and cooling facilities for mass production. Suitable for mass production, mainly used in high-end products, export products, products with tolerances, and its processing technology is stable and easy to operate.
