Polishing operations are a time-consuming and expensive process, and following certain rules can reduce the cost of polishing operations. Every step of polishing must be kept clean, which is the most important.

Polishing considerations:

1. Polishing must be done in a clean and dust-free room. Because hard dust particles can contaminate the abrasive material and damage the mold surface that is close to completion.

2. Each polishing tool uses only one level of polished diamond paste and is stored in a dust-proof or sealed container.

3. When you want to switch to a finer grade of sand number, pay attention to whether the grade of sand number completely covers the upper level (thicker) sand grains. You must wash your hands and workpiece.

4. Deal with corners, corners and rounded corners when polishing is difficult.

5. Special care should be taken when handling sharp corners and corners. Be careful not to form rounded corners or rounded edges. Try to use harder polishing tools to grind the mold and grind the stone.

Factors affecting surface polishability

The method of grinding can make the surface of the mold smooth, and the degree of smoothness is related to the following factors:

1. The quality of the steel (uneven hardness of the steel surface or differences in characteristics tend to increase the difficulty of polishing).

2. Heat treatment process (heat treatment affects polishing performance in many ways).

3. Polishing technology (the polishing process and the use of polishing consumables directly affect the polishing effect).
