Stainless steel has become a widely used engineering material because of its excellent corrosion resistance, good mechanical properties, processing performance of plane grinding and polishing machine and better welding performance. At the same time, through different polishing methods, the surface of various stainless steel plates, pipes, bars and profiles can have different levels of surface finish, which greatly improves the appearance of stainless steel and achieves aesthetic effect. For different metal materials, different use occasions and different requirements on the surface of metal workpiece, different grinding methods or combination of several grinding methods must be used to grind the workpiece to meet the requirements of use.
The "chemical grinding" of plane grinding and polishing machine is a process that makes the convex part dissolve preferentially, improves the metal surface roughness and obtains smooth and bright surface by comparing the tiny convex part and concave part on the ground surface. "Mechanical grinding" is the process of removing the convex part of the ground surface by cutting, abrasion or plastic deformation to obtain a smooth and bright surface.
