Mechanical polishing of the inner surface of the stainless steel hose

There are rotating and linear polishing. Here is an example of rotary mechanical polishing: mechanical polishing equipment is relatively simple, power and polishing discs and polishing equipment are relatively simple, power and polishing discs, and polishing wax. The cloth disc and cloth disc made of graded fine sand are polished back and forth multiple times on the inner and outer surface of the tube, and the finish can reach Ra≤0.2-0.4μm.


Compared with electrolytic polishing, mechanical polishing has simple equipment, low technical content, easy to master, low cost, and will not damage the tube and cause scrap, so it is widely used. However, the corrosion resistance of the printed layer on the surface of electrolytic polishing is much better.
