Mirror roll specific manufacturing process: procurement of Raw materials-conditioning-rough car accessories assembly-test balance-heat treatment-finishing-roller surface-electroplating-finishing-polishing-finishing-quality inspection-packaging and so on. In the process of mirror roller, quenching and tempering and heat treatment are to improve the performance of the material, so as to achieve the desired effect. In order to improve the function of anti-rust, anti-wear and anti-adhesion of the roller, the surface of the roller is electroplated with chromium according to its GE. The finishing and grinding of the later stage are the key factors to ensure the flatness, balance, roundness and coaxality of the mirror roll. In addition, according to the use of mirror roller environment, roller internal design of different channel structure, can be in and out of the water on both sides or the same side. At present, we produce mirror roller, Surface finish up to RA0.01.
