First of all, when using plasma polishing machine, we should pay attention to whether the operation of the polishing machine is standard. We can not operate the polishing machine blindly, which is easy to damage the polishing machine. When using the plasma polishing machine, it is necessary to prevent the overload operation of the polishing machine, because it will directly affect the service life and operating power of the plasma polishing machine; In addition, when using the polishing machine, if there is a problem with the plasma polishing machine, it should stop to check, and should not continue to use the polishing machine.

Secondly, polishing is divided into two stages, the first stage is rough polishing. It refers to removing the damaged layer of polished workpiece. This stage should have a large polishing rate. The surface damage caused by rough polishing is the secondary factor, but it should be as small as possible; The second is fine polishing, which means to remove the surface damage caused by rough polishing and reduce the degree of polishing damage.
