Gases Consumption about fiber laser metal cutter — Jennifer
With the fast development of metal fiber laser metal cutter, the gas consumption with different metal materials are also different . Today we will share something about the gas usage.
Taking one examples as the followings for fiber laser metal cutter
In China, one bottle of Liquid Oxygen is 50$/bottle, Standard oxygen or nitrogen gas bottle is 40L/bottle.
1mm Carbon steel 40L/40minutes
2mm Carbon steel 40L/50minutes
3mm Carbon steel 40L/60minutes
4mm Carbon steel 40L/70minutes
5mm Carbon steel 40L/80minutes
6mm Carbon steel 40L/90minutes
8mm Carbon steel 40L/110minutes
10mm Carbon steel 40L/130minutes
For carbon steel, the thicker fiber laser metal cutter, the less Oxygen pressure you need, because if use higher Oxygen pressure for thicker metal sheet, it will be burned.
1mm stainless steel 40L/30minutes 20
2mm stainless steel 40L/30minutes
3mm stainless steel 40L/30minutes
4mm stainless steel 40L/30minutes
Generally speaking, the thicker metal sheet, the higher Nitrogen pressure it needs.
For example, if cut 1mm ss, use 10kg Nitrogen. If cut 4mm ss, need 20kg Nitrogen.
But in order to keep high cutting speed for thin metal sheet , such as 1mm.
So we suggest client to adjust same pressure, all of them are 20kg, in this way, it can not only make sure of high speed of cutting thin metal sheet, also it can make sure of cutting thick metal sheet.
In addition, many clients will also consider about the relation between Nozzles’ diameter & Cutting plate.
The cutting nozzles significantly influence the laser cutting process. For example, when we have to deal with low-pressure laser cutting, smaller nozzles are require. Conversely, when the material machining calls for a higher-pressure cut, then we need to use larger nozzles.
Generally, different cutting materials are with different nozzles diameters (Both the Single & Double nozzles) in fiber laser metal cutter.
– For the carbon steel with 2000w cutter’s cutting range:
It should be with double nozzle with 1.2, 1.5 and 2.0 diameter, and with the O2 auxiliary gas;
– For the stainless steel & aluminium with 2000w cutter’s range:
It should be with single nozzle with 2.0, 2.5. 3.0. 3.5(optional) with the N2 auxiliary gas;
