The repair methods of scratches on the surface of the aluminum cover of the machine vary according to the depth of the marks and the specific situation. The following are some common repair methods:

1. Polishing method: If the scratch is not too deep, you can use a grinder and fine sandpaper to polish it to remove the scratch. However, it should be noted that the grinding should be gentle and uniform to avoid further damage to the surface, and to avoid surface deformation caused by excessive grinding.

2. Polishing method: For shallow scratches, polishing repair method can be adopted. You can use an electric polishing machine or a manual polishing plate, and polish it with gradually refined grinding paste until the surface is smooth and flat.

3. Spray painting: If the scratches are deep and cannot be repaired by the above methods, you can consider spraying Metallic paint to repair them. First, clean the impurities and dirt on the surface, then polish and render with fine sandpaper, and finally spray with metallic paint.

4. Replacement method: If the scratch is too deep or large to be repaired by the above method, the aluminum cover needs to be replaced. Need to find the same specification, model or custom-made aluminum cover, and then replace it.

It is necessary to choose an appropriate repair method according to the specific situation, and pay attention to the protection of the surface during the repair process to avoid greater damage caused by improper operation.

Magnetic grinding machine is a kind of equipment that uses magnetic force and abrasive particles to process metal surface. Its working principle is as follows:

major component

Magnetic grinding machine is mainly composed of motor, reducer, grinding disc, hydraulic system and control system. Among them, the grinding disc is usually round or oval, and the inner wall is covered with grinding wheel or grinding paste. Different types and specifications of grinding discs can be selected according to needs.

principle of operation

Firstly, the parts to be processed are placed in the grinding disc, and a certain magnetic field is generated between them. Then, the motor and hydraulic system are started to make the grinding disc start to rotate and vibrate, and at the same time, a certain pressure is applied through the hydraulic system to ensure the close contact between the parts and the grinding disc.

With the rotation of the grinding disc, the abrasive particles covered on the surface continuously cut and polish the surface of the part, thus removing the defects such as burrs, scales and pits on the surface, and improving the flatness, smoothness and accuracy of the surface. The magnetic field plays the role of restraining the position of parts and strengthening the friction between abrasive particles and the surface, thus improving the machining quality and efficiency.

The whole process can be automatically controlled and monitored by the control system to ensure the processing quality and efficiency. It should be noted that appropriate parameters and materials should be selected according to different types and specifications of grinding discs during operation, and attention should be paid to the protection of equipment and parts surfaces.
