Laser cutting machine for cutting stainless steel when common sense, auxiliary gas processing method for oxygen, nitrogen, or air, depending on the type of processing to choose auxiliary gases.
Of course, different gas its cut surface oxidation degree is different, also have certain influence to cutting speed.
When the panel thickness is less than 3 mm, because of the oxidation effect can achieve high speed.
But when the panel thickness is greater than 3 mm, no oxidation using nitrogen with the molten metal flow during cutting, can improve the speed of cutting.
Use air close to the processing features of nitrogen, but in the cut surface roughness and viscous slag quantity effect is not as good as using nitrogen gas.
After the oxidation of the surface of the cut surface hardness is about 2 times, but the scope is small.
This feature and the surface roughness is good without oxidation cutting, the cutting surface coarse grinding does not go bad easily, and the use of oxygen processing surface grinding.
