Advantages and disadvantages of three polishing methods for stainless steel coil plate

The commonly used polishing methods of stainless steel coil are mainly mechanical polishing, chemical polishing and electrochemical polishing. These three methods have their own advantages and disadvantages.

Mechanical polishing is the advantage of the smooth parts after processing, high brightness. The disadvantage is that the labor intensity is high, the pollution is serious, and those relatively complex parts can not be processed, the luster after polishing is not consistent with the luster after the mechanical polishing is not long, giving a person the feeling is dull, rusty, more suitable for processing simple parts, small and medium-sized products.

The advantage of the second kind of chemical polishing is that the processing equipment investment is less, some complex parts can also be polished, polishing speed, high efficiency, polished stainless steel anticorrosion is good. The disadvantage is that the brightness is poor, there is gas overflow, the need for ventilation equipment, heating is more difficult, suitable for processing small batch complex parts and small parts of stainless steel products with low brightness requirements.

The third is electrochemical polishing, electrochemical polishing is the polished stainless steel mirror luster to maintain long, the process is relatively stable, less pollution, low cost, good corrosion resistance. Its disadvantage is high anti-pollution, processing equipment one-time investment is relatively large, complex parts to tooling, auxiliary electrode, mass production also need cooling facilities. This polishing method is suitable for mass production, mainly applied to high-grade products, export products, products with tolerances, its processing technology is stable, simple operation.
