When polishing aluminum alloys, it is usually better to use a softer polishing material.

Aluminum alloys have relatively low hardness, and using too hard a polishing material may cause the following problems:
Scratches and Scratches: Excessively hard polishing materials may leave nicks or scratches on the surface of the aluminum alloy, spoiling the finish.
Excessive Material Removal: Polishing materials that are too hard may over-remove material from the aluminum alloy surface, resulting in increased surface roughness or dimensional changes.

Heat accumulation: Excessively hard polishing materials may generate excessive frictional heat during the polishing process, resulting in local heating of the aluminum alloy surface, which may cause deformation or thermal cracks.

Therefore, using a softer polishing material is more suitable for polishing aluminum alloys, and the degree of softness and hardness selected should be determined according to the specific aluminum alloy material and polishing requirements. Softer polishing materials can effectively remove blemishes and improve the finish of the aluminum alloy surface without excessive cutting and damaging the surface.

In addition, when polishing aluminum alloys, care should also be taken to control polishing parameters such as speed, pressure and the use of lubricants to ensure the stability of the polishing process and the best results in surface quality. If you are unsure about which polishing material and parameters to choose, it is recommended that you conduct small-scale trials to determine the best polishing method for your specific application.

If magnetic grinder products bump into each other during use, here are some possible solutions:
Adjust the arrangement of the workpieces: ensure that the workpieces are properly dispersed in the working area of the magnetic grinder, and avoid too densely packed. This reduces collisions between workpieces.

Increase the filling amount of magnetic grinding fluid: By increasing the filling amount of magnetic grinding fluid, the contact and collision between workpieces can be effectively reduced. The magnetic grinding fluid can play the role of buffering and separation to a certain extent.
Use the right abrasive and stone: Choose the right abrasive and stone to match the size and shape of the workpiece. Soft or fine abrasives and grinding stones can reduce the force of the collision and avoid too violent a collision.

Adjust the parameters of the magnetic grinding machine: According to the actual situation, adjust the parameters of the magnetic grinding machine, such as rotation speed, vibration amplitude, etc. Properly adjusting these parameters can change the interaction force between workpieces and reduce the occurrence of collisions.

Check the condition of the magnetic grinder: Make sure that the parts and accessories of the magnetic grinder are not damaged or loose. If any damage or abnormality is found, it should be repaired or replaced in time.

Provide appropriate protective measures: For workpieces that are small in size or easy to collide with each other, appropriate fixtures or protective materials can be used for isolation to prevent collisions.

Specific countermeasures may vary depending on the model of magnetic grinder, operating conditions, and workpiece characteristics. In actual operation, it is recommended to follow the instructions and safety operating procedures of the magnetic grinding machine, and take corresponding preventive measures according to the specific situation.
