How to avoid scratching the surface of copper during magnetic polishing

In the process of magnetic polishing, the following measures can be taken to avoid scratching the copper surface:

1. Select appropriate magnetic powder: The magnetic powder used for magnetic polishing should have appropriate hardness and particle size to reduce scratches on the surface of copper parts.

2. Control the strength of magnetic force: If the magnetic force is too strong, the magnet or magnetic powder will exert great pressure on the surface of copper, which will increase the possibility of scratching. Therefore, it is necessary to adjust the intensity of magnetic force according to the specific situation to make it moderate.

3. Use suitable abrasive: In the process of magnetic polishing, abrasive and magnetic powder are needed for grinding. Choose abrasive with moderate hardness to reduce the risk of scratching the surface of copper parts.

4. Control polishing time: Too long polishing time may lead to excessive magnetic polishing and increase the risk of scratches. Therefore, in magnetic polishing, it is necessary to control the polishing time to ensure that the copper surface will not be excessively polished.

5. Pay attention to the grinding method: During magnetic polishing, the magnet and magnetic powder will generate friction to grind the copper surface. Therefore, it is necessary to control the grinding mode to avoid excessive friction and reduce the risk of scratches.

It should be noted that the above measures are just some common methods, and the specific situation needs to be adjusted and implemented according to the actual operating experience and the characteristics of magnetic polishing equipment.
