If the noise of the nail polish machine is too loud, you can try the following solutions:

Check the tool or grinding head: Ensure that the tool or grinding head is installed correctly and tightened. If the cutting tools or grinding heads are loose or damaged, it may cause excessive noise from the grinding machine.

Cleaning and lubrication: Clean the internal and external components of the polishing machine to ensure that there is no dust or impurities interfering with the machine's operation. Meanwhile, use appropriate lubricating oil to lubricate the bearing part of the grinder.

Adjusting speed: Reduce the speed of the polishing machine, which may reduce noise. You can refer to the manual for specific models to learn how to adjust the speed.

Using shock-absorbing pads: When using a polishing machine, shock-absorbing pads can be placed under a table or other support to reduce the spread of noise.

Replace the machine or consult a professional: If the above methods are ineffective and the noise is still too loud, it is recommended to contact the manufacturer or consult a professional in nail art equipment for more advice or replace the polishing machine with a lower noise one.
