CNC milling machines require the use of appropriately sized air compressors, which should be determined based on factors such as the CNC milling machine model, processing materials, and one-time processing quantity.

Firstly, why does a CNC milling machine require the use of an air compressor?

CNC milling machine is a high-precision machining equipment that requires a large amount of gas resources to work. The pneumatic system is the core system on the CNC milling machine, which controls various pneumatic components to achieve automatic machining by providing compressed air. Therefore, CNC milling machines must be equipped with appropriately sized air compressors to meet the air source requirements.

Secondly, how to choose a suitable air compressor?

Choosing a suitable air compressor requires considering the following factors:

1. CNC milling machine model: Different models of CNC milling machines have different requirements for air compressors, and their air source requirements can generally be confirmed from their technical parameters.

2. Processing materials: If processing hard materials, higher compressed air pressure is required, and a large air compressor is required accordingly; If processing soft materials such as aluminum alloy and brass, a small air compressor can be chosen.

3. Quantity of one-time processing: If large-scale continuous processing is required, a large amount of air supply is required, so a higher capacity air compressor needs to be installed.

Thirdly, precautions for using an air compressor

1. Regularly clean, maintain, and inspect the air compressor to ensure its normal operation.

2. Avoid prolonged high-speed operation, turn off the engine promptly after processing, and restart it when needed for reuse.

After installing the air compressor, it is necessary to make appropriate adjustments and settings according to the needs of the CNC milling machine.

4. Follow safety operating procedures to prevent accidents.

In short, choosing a suitable and convenient air compressor is crucial for the machining stability and efficiency of CNC milling machines.
