Auxiliary gas laser cutting machine mainly used in: a, laser gas (
The laser generator is used to produce laser gas)
Second, compressed air,
Generally used to protect optical path, some manufacturer also used for protection of gas)
Three, auxiliary gas (
Is the gas out of the cutting machine cutting nozzle spray)
Laser cutting machine for cutting different materials with different auxiliary gases.
The thickness of the cutting material is different, its auxiliary gas pressure and requirement of flow is different.
Cutting carbon steel with oxygen, and its purity is in commonly 99.
5% or higher.
The main role is combustion and blew the melt off cutting objects.
Pressure and flow rate of each different laser cutting machine manufacturers, with the nozzle size, cutting material thickness are inseparable.
General requirements at zero pressure.
3 -
0.
General 0 8 mpa, cut the mouth.
02-0.
05Mpa。
Traffic is bad to say, such as carbon steel cutting 22 mm, the flow of some manufacturers to achieve 10 m3 / h (
Including the protection of the double nozzle with oxygen)
Have high request for the purity of nitrogen (
More than 8 mm stainless steel, in particular, require general to reach 99.
The purity of 999%)
The flow according to the cutting nozzle model have change, but are very big, such as cutting 12 mm stainless steel to some manufacturer to 150 m3 / h and cut 3 mm, as long as 50 m3 / h the following traffic.
