The composition of laser cutting machine gas path

by：Transon 2020-10-27

The normal work of the laser cutting machine without the help of auxiliary gas. Auxiliary gas may be air, oxygen or nitrogen. The composition of gas path is divided into two parts: 1. Cutting when the cutting gas supply, auxiliary melting and blows away the slag, and so on. There are clean and dry compressed air, high purity oxygen and high purity nitrogen. 2. Supply of lathe bed gas laser cutting machine, and for clamping the workbench cylinder and dust removal etc. All of them are clean and dry compressed air. Cutting is divided into three kinds of gas: compressed air, oxygen and nitrogen, and the three gas can choose according to different requirements. 1. The use of compressed air is mainly used for cutting thin plate, reduce the cost. 2. Oxygen is mainly used for cutting of ordinary carbon steel. 3. Nitrogen is mainly used for cutting stainless steel and alloy steel. According to different materials to choose different cutting gas. In the cutting gas system due to the pressure sensor was installed inside, make sure that the machine at the time of gas pressure is not enough to stop the work in time, avoid the abandonment of the cutting parts. The threshold pressure can be regulated by the upper pressure sensor screw set, cut with compressed air and oxygen can also be controlled by the program proportional regulator to adjust.
