The essence of polishing is the grinding process that uses a polishing material to physically smooth the surface of the workpiece by physical action or electrical, magnetic and chemical methods. Polishing can be divided into rough polishing, medium polishing and fine polishing. The polishing materials used in each process of polishing are different.

The essence of polishing is the grinding process that uses a polishing material to physically smooth the surface of the workpiece by physical action or electrical, magnetic and chemical methods. Polishing can be divided into rough polishing, medium polishing and fine polishing. The polishing materials used in each process of polishing are different, and even the locations in different polishing processes are also separated. For example, the location of the rough throwing and the spotting are in the Different places to complete.
It should also be noted that the residue of the previous process on the surface of the workpiece must be cleaned after each polishing step using different polishing materials. After the polishing material rough-casts the workpiece, it reaches the requirements of the rough polishing process. Next, the fine polishing is performed. Once the polishing is performed, the workpiece needs to be carried out in a dust-free workshop with a higher environmental requirement and a finer polishing material to ensure the air. No dust particles stick to the surface of the workpiece.
After the fine polishing process is completed, the surface of the workpiece should be dust-proofed. At the same time, it is necessary to remove the residue of polishing materials and other additives to ensure the surface of the workpiece is clean. Finally, the workpiece is sprayed with anti-rust coating to prevent the workpiece from being used for a long time. The working environment causes rust and affects the service life.
