Advantages and disadvantages of three polishing methods for stainless steel
The polishing methods commonly used in stainless steel are 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 finished part has good leveling property and high brightness. The disadvantages are that the labor intensity is high, the pollution is serious, and the complicated parts cannot be processed, and the gloss cannot be consistent, the gloss is not kept for a long time, and the stagnation and rust are caused. More suitable for processing simple, medium and small products.
2. Chemical polishing.
The advantage is that the processing equipment has less investment, the complicated parts can be thrown, the speed is fast, the efficiency is high, and the corrosion resistance is good. The disadvantage is that the brightness is poor, there is gas overflow, ventilation equipment is needed, and heating is difficult. It is suitable for processing small batches of complex parts and small parts with low brightness requirements.
3, electrochemical polishing
The advantage is that the specular gloss is kept long, the process is stable, the pollution is small, the cost is low, and the corrosion resistance is good. The disadvantages are high anti-pollution, large investment in processing equipment, complicated tools, auxiliary electrodes, and mass production facilities. Suitable for mass production, mainly used in high-grade products, export products, tolerance products, stable processing technology and simple operation.
