Choosing the appropriate polishing machine can not only effectively improve work efficiency, but also significantly improve the surface quality of the product.

The following is a selection guide and common questions for polishing machines, providing you with a more comprehensive understanding and assistance.

1、 Selection guide for polishing machine

Some polishing machines are suitable for hard materials, while others are more suitable for soft or high-precision materials.

Polishing effect: If you need a high brightness mirror effect, you should pay attention to the speed of the polishing machine and the material of the grinding head when purchasing; If only the surface oxide layer is removed, then choose the basic version.

Type Selection

Pneumatic and electric: Pneumatic polishing machines are commonly used in heavy industry and have higher stability, while electric polishing machines are easy to carry and operate, suitable for a wide range of processing needs.

Adjustable speed: The adjustable speed polishing machine can adjust the speed according to different materials or processing requirements, improving processing flexibility and effectiveness.

Power and speed

Generally speaking, the power of a household polishing machine is around 500W, while the power of an industrial polishing machine can reach over 1000W.

Rotational speed: The rotational speed of the polishing machine directly affects the processing speed and polishing effect.

For precision polishing, lower speed equipment is usually chosen, while for rough machining, high-speed equipment can be selected.

Grinding head or polishing disc material

Wool grinding heads are suitable for high brightness polishing, sponges are suitable for delicate surface treatment, while nylon is suitable for rough polishing and cleaning surface stains.

Compatibility: Confirm whether the polishing machine supports multiple types of grinding heads or polishing discs to ensure that it can meet different processing needs.

Safety and durability

Durability: Check the shell material, heat dissipation design, and internal component quality of the polishing machine to ensure that the equipment is not easily overheated or damaged during long-term use.

Brand and after-sales service

After sales service: Ensure that the selected brand provides comprehensive after-sales service, including warranty, repair, and spare parts supply, to facilitate future maintenance and repair.

2、 Common problems with polishing machines

Solution: Clean the grinding head, replace the clean polishing disc, adjust the speed, and choose a suitable grinding head material to reduce scratches.

Uneven polishing effect

Solution: Maintain uniform force when moving the device, regularly check the wear of the grinding head, and replace it with a new one if necessary.

Polishing machine overheating

Solution: Pause cooling at regular intervals to avoid prolonged continuous work; Heat dissipation devices can be installed in the equipment or polishing machines with overheating protection can be selected.

Excessive polishing dust

Solution: Use a vacuum cleaner or choose a polishing machine with a dust collection system to improve ventilation in the working environment.

Loose polishing disc or grinding head

Solution: Check and tighten the fixing device before each use to prevent the polishing disc from loosening.

Low polishing efficiency

Solution: Choose a polishing machine with higher power and speed, and replace the grinding head or polishing disc suitable for the material.

conclusion

At the same time, regular inspection and maintenance of the polishing machine can extend its service life and maintain good processing results.
