In the processing of parts, the requirements for strength and toughness are relatively high. Its working performance and service life are closely related to its surface properties. However, the improvement of surface properties cannot be achieved simply by relying on materials, and it is also a very uneconomical approach. However, in actual processing, its performance has reached the standard. At this time, surface treatment technology is required.

Mold polishing technology is a very important link in the field of mold surface treatment, and it is also an important process in the processing of workpieces.
