1, the polishing of acrylic mirror is mainly in its processing, the polishing method is mainly diamond polishing and flame polishing. The polishing paste is often used in the entire polishing process to promote the polishing effect of the acrylic mirror. There is a big difference between the polishing and grinding of acrylic is that polishing does not change the dimensional accuracy of the workpiece, and the fine lines and spots on the surface of acrylic mirror products are removed, which promotes the surface finish of acrylic mirror products, and also reduces the fog until the mirror luster appears.

Be careful not to concentrate too much on a certain part of the polishing, so as to avoid the formation of local friction overheating and processing depression.
