Problems solved by technology

Polishing is an important process in stainless steel processing and production. Traditional mechanical polishing tends to damage the workpiece. Local high temperature and hardening tend to occur during friction, which in turn changes the original metallographic structure of the metal surface and affects the further processing of stainless steel. Electrolytic polishing overcomes the disadvantages of mechanical polishing very well, but the existing electrolytic polishing technology has high temperature requirements, usually above 90°C, to ensure the quality of electrolytic polishing, which undoubtedly increases the production cost. In addition, air bubbles are easy to be generated during electrolysis, which affects the surface quality of the polished workpiece, and the method still needs further improvement
