What are the methods for polishing the surface of stainless steel?

The surface of the stamping parts made by stamping processing needs to be polished to make the surface of the workpiece smooth, smooth and beautiful, and improve the quality of the product. So, do you know what treatment methods are available for stainless steel surface polishing? Now let's learn this together. Stainless steel surface polishing treatment methods are mainly divided into mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing, fluid polishing, and magnetic abrasive polishing. 1. Mechanical polishing Mechanical polishing is a polishing method that relies on cutting and plastic deformation of the surface of the material to remove the polished convexities to obtain a smooth surface. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, mainly manual operations, special parts such as rotation For the surface of the body, auxiliary tools such as a turntable can be used, and the method of ultra-precision polishing can be used for the surface quality requirements. 2. Chemical polishing Chemical polishing is to make the surface microscopic convex part of the material in the chemical medium dissolve preferentially than the concave part, so as to obtain a smooth surface. The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency. 3. Electrolytic polishing The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, by selectively dissolving tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the influence of the cathode reaction can be eliminated and the effect is better. 4. Magnetic Grinding and Polishing Magnetic grinding and polishing uses magnetic abrasives to form abrasive brushes under the action of a magnetic field to grind the workpiece. This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions. 5. Ultrasonic polishing Put the workpiece into the abrasive suspension and put it in the ultrasonic field together, relying on the vibration of the ultrasonic to make the abrasive grind and polish on the surface of the workpiece. Ultrasonic machining has a small macroscopic force and will not cause deformation of the workpiece, but it is difficult to manufacture and install tooling. Ultrasonic processing can be combined with chemical or electrochemical methods. 6. Fluid polishing Fluid polishing relies on high-speed flowing liquid and the abrasive particles carried by it to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, hydrodynamic grinding and so on.
