How to do polishing stainless steel cnc parts ?
The polishing methods commonly used in stainless steel are mechanical polishing, chemical polishing, and electrochemical polishing.
1. Mechanical polishing. The advantage is that the finished part has good leveling property and high brightness. The shortcomings are labor intensity, serious pollution, and complicated parts can not be processed, and the gloss can not be consistent, the gloss retention time is not long, boring and rusting. 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. The advantage of electrochemical polishing is that the specular gloss remains long, the ceramic steel pipe process is stable, the pollution is low, the cost is low, and the corrosion resistance is good. The shortcomings 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.
