During the working process of the laser cutting machine, the purity and pressure of the gas need to be optimized and adjusted according to the type, thickness and cutting quality requirements of the cutting material. Here are some optimization suggestions:

1. Balance purity and pressure

High-purity gases paired with appropriate pressure can significantly improve cutting quality and speed. For example, when cutting stainless steel, using high-purity nitrogen and moderate gas pressure can produce smooth, oxide-free cuts. With different materials and cutting thicknesses, the right combination of purity and pressure needs to be found to meet specific production needs.

2. Adjust process parameters

Other process parameters during the cutting process, such as laser power, cutting speed, focus position, etc., also need to be coordinated with the purity and pressure of the gas. By comprehensively adjusting these parameters, the cutting effect can be further optimized. For example, when cutting thin aluminum plates, high-pressure nitrogen and higher laser power can be used to increase cutting speed and quality.

3. Perform testing and calibration

Testing and calibration are crucial before mass production. Through experiments, the best combination of gas purity and pressure can be found to ensure that the cutting effect is stable and meets production requirements. Testing can also help identify potential problems, such as the impact of gas impurities on cut quality and changes in cutting speed under different pressures.

By rationally adjusting these parameters and combining them with specific cutting needs, the efficiency and quality of the cutting process can be significantly improved and the need for subsequent processing can be reduced. For cutting operators and engineers, understanding and mastering the effects of gas purity and pressure is key to ensuring high-quality cutting results.
