Laser processing is a kind of thermal processing. And in the thermal process it will produce heat which will cause the deformation of sheet. Within a small range of excessive heat concentration can produce the material combustion. All of these have a detrimental effect on the material.
According to different materials, different cutting requirements, using different cutting auxiliary gas. Its purpose is to get the best cutting quality.
Cutting boards such as stainless steel or aluminum, generally using nitrogen gas as auxiliary, the cooling and protection. The carbon steel cutting with oxygen, the cooling and accelerate the combustion speed cutting purpose.
The types and functions of gas are commonly used to laser cutting machine:
1, air: ① as cutting gas used as cooling cutting head and used as a light path (internal dust protection lens extension lens use time)
2, general oxygen: as the gas cutting carbon steel (oxidizing) purity 99.5%
3, pure nitrogen: as the gas cutting stainless steel (cooling) purity 99.9% (cutting carbon steel at 3/4)
4, high purity nitrogen: use as gas, laser Purity: 99.999%
5, high pure helium: as the use gas, laser Purity: 99.999%
6, high pure carbon dioxide: as the use gas, laser Purity: 99.999%
