The composite polishing technology used by stainless steel polishing machine to process workpieces adopts the most advanced stainless steel polishing machine for polishing, which has high polishing efficiency and precision and meets the requirements of mirror polishing. Stainless steel polishing machine can process not only stainless steel workpieces, but also other metal workpieces.

(1) Because the composite polishing is an anode process and is carried out in the passivation zone, a good passivation effect can be obtained on the metal surface. The porosity measured by blue dot method is less than 2, and the film is dense and uniform, which is better than simple chemical passivation.

(2) The compound polishing eliminates the stress concentration on the equipment surface, eliminates the Bayer layer formed by grinding the metal surface, and improves the reliability of equipment operation.

(3) High surface accuracy can be obtained by compound polishing. Because of its electrochemical leveling ability and bright effect, composite polishing has a surface roughness of Ra0.00 1 and a surface reflectivity of over 95%, and its appearance is as beautiful as an ornament. In this way, the phenomenon of hanging materials on the surface and sticking to the wall can be eliminated, and at the same time, a good decorative effect can be achieved.

(4) The surface quality of composite polishing is better than that of chemical polishing, and there is no local corrosion, which eliminates the uneven polishing and excessive corrosion caused by the time difference between import and export during chemical polishing of large equipment.

(5) The electrochemical planarization process of composite polishing is a non-uniform dissolution process, so the surface is rich in chromium, and the chromium content of the surface is 3%-5% higher than that of the base metal, thus enhancing the metal passivation ability. The breakdown potentials all moved to above 150mv, and the pore sensitivity range was greatly reduced.

(6) The composite polishing solution is nonflammable, non-toxic and pollution-free, and the process is relatively simple, so it can be operated on site.

(7) Composite polishing does not have any side effects on the substrate, and there is no hydrogen permeation phenomenon. Composite polishing is an anode process, and there are no new ecological hydrogen atoms on the anode surface. According to the ferrite measuring instrument, composite polishing does not produce hydrogen-induced martensite transformation process.
