1. Fast cutting speed, smooth and even incision, no burrs;

2. Narrow cut, small deformation, and the cutting surface material does not harden;

3. High processing accuracy and good repeatability;

4. Simple CNC programming, wide processing range, no need for mold opening, economical and time-saving; Types of auxiliary gas sources

1. Nitrogen: It is generally used as an auxiliary gas source for processing precious metals or for processing with very high requirements;

2. Oxygen: High purity oxygen has strong oxidizing properties, causing the cutting surface to turn black and increase hardness, commonly known as “coke”;

3. Compressed air: With a wide processing range, air itself contains about 20% oxygen in the atmosphere, which can to some extent compensate for the shortage of oxygen and nitrogen. Cost of gas source Due to the higher cost of nitrogen and oxygen compared to compressed air, and their increasing prices year by year, using air as a cutting auxiliary gas can greatly reduce production costs by about half. The function of high-pressure gas source

1. Cooling prevents material hardening, that is, heat treatment;

2. The air pressure blows away the melted metal slag during cutting, preventing dust from blocking the laser nozzle and protecting and extending its service life; Requirements of laser cutting machine for compressed air source Laser cutting machines have high requirements for compressed air sources, which must not contain water or oil. Generally, users are equipped with four or even five levels of filtration to better protect the service life of the laser cutting machine. If the air source entering the cutting head contains water and oil, it will cause the protective lens to fog up in a short period of time, affecting the cutting quality. If the protective lens is not replaced in time, it may cause the internal temperature of the cutting head to rise under high-power beam irradiation, resulting in damage to the internal lens group. Post processing installation layout

1. The compressor is closely connected to the laser cutting machine, and the filter of the refrigerated dryer is sequentially connected;

2. The compressor is far away from the laser cutting machine, and two filters are installed at the end of use to process residual water and oil in long-distance pipelines;
