Most people think that stainless steel is not rusty, actually , it just like many other metals, if you touch it or it contact with air or affected by the environment would be oxidize and other stainless steel surface after machining, such as welding, punching, winding, such as heat treatment process After generating a layer of black oxidation of hardening layer, At the same time,it forms many naked eyes and invisible tiny burrs and acute Angle burrs, Normally, it is difficult to remove them with mechanical methods, because it would affect the performance of the workpiece material itself. In order to solve these problems, people make use of various methods of stainless steel and other metal surface grinding polishing treatment, is classified as follows:
1.Mechanical polishing:
A: Grinding polishing B: sandblasting POLISHING C: Grinding polishing D: Extrusion polishing
2.Chemical polishing:
A:Electrochemical chemical polishing; B. Chemical grinding and polishing
Compound grinding and polishing: mechanical method and chemical method of the combination of two grinding methods
For different metal materials, different use occasions, different requirements on the surface of metal workpiece, it is necessary to adopt different grinding methods or a combination of several grinding methods for grinding processing to make the processed workpiece meet the requirements of use.
