Fiber Laser Cutting Machine With Auxiliary Gas Mainly In Three Aspects
Fiber laser cutting machine cutting different materials require different auxiliary gas.
The thickness of cutting material, the auxiliary gas pressure and flow is different.
Cutting carbon steel with oxygen, its purity requirements are generally 99.5% or higher.
The main role is to melt combustion and blow off cutting.
Different laser cutting machine manufacturers, pressure and flow are not the same,
this is closely with the size of the cutting nozzle and the thickness of the cutting material.
Laser cutting machine auxiliary gas is mainly used in:–fiber laser cutting machine
1, laser gas (the laser used to generate laser gas)
2, compressed air (generally used to protect the optical path, and some manufacturers are also used to do the protection of gas)
3, auxiliary gas (that is, from the cutting nozzle cutting gas)
Cut stainless steel with nitrogen. The role is to eliminate the oxidation reaction and blow off the melt.–fiber laser cutting machine
High purity nitrogen requirements (especially stainless steel more than 8mm, the general requirements to achieve 99.999% purity) pressure requirements relatively large,
the general requirements of 1Mpa above.
If you want to cut more than 12mm, or thicker to 25mm stainless steel, require a higher pressure, 2Mpa above or higher.
The flow rate changes according to the model of the cutting nozzle, but it is very big.
For example, some 12mm stainless steel cutting need to cut 3mm at 150m3 / h, and the flow below 50m3 / h.
In terms of cost, cutting carbon steel with oxygen is relatively cheap,The amount of nitrogen to cut stainless steel is very large,
The thicker stainless steel requires higher nitrogen and concentration
