The effect of the laser assisted gas

Normally, blowing the gas from a laser cutting machine should be called professional gas.
The main functions are as follows:
1, cooling prevents material hardening, that is, heat treatment.
2, the air pressure will blow away the molten metal slag.
3, auxiliary combustion.
For example, oxygen cutting, oxygen combustion, cutting will be more energy. Of course, for non-metal laser cutting machine, blowing one can prevent fire, and the other can prevent dust blockage of laser jet nozzle. Some special materials also need to increase blowing to achieve the goal of not changing colors. And from the micro carving laser engraving machine, carving cutting bamboo wood products, paper, leather, cloth and other surface materials to reduce the temperature to eliminate the surface carbonization, keep the original color to achieve the best engraving effect. The utilization rate of light.
