How to choose auxiliary gas for fiber laser cutting machine?
The most widely used auxiliary gases that can be used by fiber laser cutting machine are mainly air, nitrogen, oxygen and argon. Now I will show you how to use them in different materials.
A.Air
Air can be supplied directly by air compressor. So it’s much cheaper compared to other gases. Although air contains about 20% oxygen, but it’s cutting efficiency is far less than oxygen. Air cutting capacity is similar to nitrogen.
It’s widely used for carbon steel, stainless steel, aluminum, aluminum alloy, copper, brass etc. But if you have high requirements for cutting quality, we do not suggest use air to cut stainless steel, copper, brass, aluminum, aluminum alloy etc cause the air will oxidize the base metal.
B.Nitrogen
It’s widely used in stainless steel, copper, brass, aluminum, aluminum alloy,galvanized sheet etc.
C.Oxygen
It’s widely used in carbon steel etc
3.Argon
The cost of argon is much expensive, it’s widely used for Titanium, Titanium Alloy.
Why we do not recommend you choose second-hand fiber laser cutting machine?
a.The laser source is the core part of fiber laser cutting machine, the cost of the laser source is expensive; For a second hand fiber laser cutting machine, the using life of laser source is reduced, so it will reduce the cutting efficiency. In future,you will spend more money to purchase a new laser source;
b.The function of CNC machine tools are updated quickly, while the function of second-hand equipment are backward, which is not conducive to the fine processing in future.
c.With bad after-sale service support, it’s hardly to get the service from the original factory when you need support;
d.Incomplete accessories will affect the cutting progress and increase the using cost.
