Auxiliary Gas of Fiber Laser Cutting Machine
Auxiliary Gas of Fiber Laser Cutting Machine, When using a fiber laser cutting machine, it needs to be equipped with auxiliary gas.
How to choose the auxiliary gas? Auxiliary gas usually contains oxygen, nitrogen, and compressed air. The applicable conditions for the three gases are different. So the following are the differences between them.
1. Compressed air
Choose Auxiliary Gas of Fiber Laser Cutting Machine, Compressed air is suitable for cutting aluminum sheets and galvanized steel sheets, which can reduce the oxide film and save costs to some extent.
Generally, the cutting sheet is relatively thick, and the cutting surface is not required too perfect.
Choose Auxiliary Gas of Fiber Laser Cutting Machine, Nitrogen is a kind of inert gas. It prevents sheet surface from oxidation during cutting and prevents burning (it is easy to occur when the sheet is thick).
Oxygen mainly acts as a combustion aid, which increases the cutting speed and thickens cutting thickness,
suitable for thick plate cutting, high-speed cutting, and sheet cutting, such as some large carbon steel plates.
Although increasing the gas pressure can improve the cutting speed, the high cutting speed also will cause a decrease after reaching a peak value. Therefore, when debugging the machine, it is very important to control the air pressure.
