A woodworking sander is a tool or machine that uses an abrasive cloth or paper to make the surface of a wooden workpiece smooth.

It is inevitable that there will be some defects in the reprocessing process of metal-related mechanical equipment or parts. Therefore, the surface processing procedure of the last item is very important, and the function of surface beautification and protection is carried out, thereby improving the performance of metal parts and avoiding rust.

Generally, the steel blackening (black oxidation) treatment can effectively improve the corrosion resistance, but the protective effect is still quite limited. Oil immersion or subsequent rust prevention treatment is still required to really improve the corrosion resistance and lubricity of the blackened layer.
