What should I do if the gas pressure of the CNC laser cutting machine cutting section is insufficient?

When the CNC laser cutting machine encounters the problem of insufficient gas pressure on the cutting section during the cutting process, the following measures can be taken to solve it:

First check whether the gas source is sufficient and ensure that there is enough cutting gas in the gas cylinder or gas supply system. Confirm that the gas source switch is fully turned on and is not in a half-open or closed state. Check whether the gas supply pipeline is unobstructed and there is no leakage or blockage. Observe the gas pressure gauge to confirm whether the current gas pressure reaches the set value. If the pressure is insufficient, it needs to be adjusted. Increase the gas pressure by adjusting the pressure reducing valve to reach the pressure range required for cutting. Generally, the gas pressure setting range of the laser cutting machine is between 0.3-2.0Mpa, and the specific value needs to be determined according to the cutting material and cutting parameters.

Check whether the gas flow meter is working properly and there is no malfunction or damage. If the flow meter is set incorrectly, insufficient gas flow may occur. According to the cutting requirements, adjust the flow meter settings to ensure that the gas flow is sufficient and stable.

The nozzle is a key component for gas ejection. If the nozzle is blocked or damaged, it will affect the gas flow and cutting effect. Therefore, it is necessary to check the status of the nozzle regularly to ensure that it is unobstructed. If the nozzle is found to be clogged or damaged, it should be cleaned or replaced in time. When cleaning, you can use appropriate cleaning agents and tools to ensure that the inside of the nozzle is clean and free of impurities.

Too fast or too slow cutting speed may lead to insufficient gas pressure. According to the characteristics and thickness of the cutting material, adjust the cutting speed to the appropriate range. The size of the laser power will also affect the cutting effect. In the case of insufficient gas pressure, the laser power can be appropriately increased to improve cutting efficiency and quality.

If the above measures cannot solve the problem, it is recommended to contact the technical support team or after-sales service department of the CNC laser cutting machine. They can provide professional technical support and solutions to help solve the problem of insufficient gas pressure in the cutting section.

Solving the problem of insufficient gas pressure in the cutting section of CNC LASER CUTTING MACHINE requires multiple aspects, including checking the gas source, adjusting the gas pressure, checking the gas flow meter, cleaning or replacing the nozzle, optimizing the cutting parameters, and contacting technical support. By comprehensively applying these measures, the smooth progress of the cutting process and the stable improvement of cutting quality can be ensured.
