1. Fluid polishing: relying on the high-speed flowing liquid and the abrasive particles it carries to scour the surface of the workpiece to achieve the purpose of polishing. Driven by hydraulic pressure, the liquid medium carrying abrasive particles flows back and forth across the surface of the workpiece through the sandblasting gun at high speed. The medium is mainly made of a special compound with good fluidity at low pressure and mixed with green silicon carbide, and its silicon carbide powder can be used.
2. Mechanical polishing: it is a polishing method that relies on the plastic deformation of the surface of the diamond cutting material to remove the polished convex part to obtain a smooth surface. The polishing sheet is mainly operated by hand. For special parts such as the surface of the rotary body, auxiliary tools such as turntables can be used. , the method of ultra-fine grinding and polishing can be used if the surface quality is high.

3. Electrolytic polishing: the surface is smoothed by selectively dissolving the tiny protrusions on the surface of the material. Compared with chemical polishing, it can eliminate the influence of cathode reaction, and the effect is better. The electrochemical polishing process is divided into macro leveling and micro leveling.
4. Chemical polishing: Let the microscopic protruding part of the surface of the material dissolve preferentially in the chemical medium compared with the concave part, so as to obtain a smooth surface. It can polish workpieces with complex shapes without complex equipment, and can polish many workpieces at the same time, with high efficiency. The core problem of chemical polishing is the preparation of polishing fluid.
5. Ultrasonic polishing: Put the workpiece into the emery suspension and place it in the ultrasonic field together, and rely on the oscillation of the ultrasonic wave to make it 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 machining can be combined with chemical or electrochemical methods.
