precision parts processing, large castings, large machinery, used for mechanical processing, CNC processing. Each mold is made up of many parts, one of which is the process part and the other is the structural part. The process parts have a direct impact on the quality of the molding products. The final quality of the process parts is finished by the finishing means in the present die processing manufacturers.
    and then look at the surface treatment of the precision parts of the die together: the content of the formed surface treatment, including the surface of the steel, such as no pores, uniform hardness, small anisotropy, low inclusions, and the stress concentration of the surface in the machining of the parts. Therefore, after processing, surface hardening is needed, and mechanical potential is eliminated through mechanical polishing, fitter grinding and polishing. Useless edges, sharp corners and orifices are obtuse. Generally, the surface of the electric machining will be 6 ~ 10&mu of the hardened and hardened layer; about M, with a gray and white color. The layer is brittle and with residual stress. The hardened layer should be fully eliminated before use. The method is to polish the surface and polish the hardened layer. To obtain high quality polishing effect, the material, shape, hardness and surface quality of the workpiece should be fully considered. It is necessary to have high quality polishing tools, high quality polishing materials, correct polishing process, rigorous personnel quality and good cleaning environment.
