Polishing methods of seamless steel pipes are as follows:
1. The advantage is that the parts are smooth and the brightness is high after processing. The disadvantage is that the intensity of labor is too great, resulting in serious pollution, and can not process complex parts, the gloss can not be consistent, the holding time is not long, mechanical polishing is suitable for processing simple parts, and small and medium parts.
2. Chemical polishing
A little bit is investment equipment, complex parts can be polished, fast, high efficiency, good corrosion resistance, the disadvantage is poor light, need ventilation equipment, heating difficulties. Suitable for small batches of complex parts and small parts that do not require high brightness.
3. Electrochemical polishing
The advantage is that the specular gloss is kept long, the process is stable, the cost is low, and the anti-corrosion is disadvantaged. The disadvantage is that the equipment has a large investment at one time, the complicated parts have to be tooled, and the auxiliary electrode is mass-produced, and the cooling device is needed. Suitable for mass production, mainly used in high-grade products, export products, tolerance products, stable processing technology and simple operation.
