Now, with the development of laser cutting technology, laser cutting more and more widely used, applied materials is also increasing. However, different materials have different properties. Laser cutting machine for cutting what kinds of materials?
1, stainless steel
Stainless steel cutting oxygen is required, in the case of edge oxidation does not matter; the use of nitrogen to obtain oxidation without Burr-free edges, you don't need to be dealt with. Surface piercing effect of coating film will be better, without sacrificing quality.
2, structural steel
The material using laser cutting of oxygen will get better results. When oxygen is used as a processing gas at the cut edges slightly oxidized. For thickness 4mm sheet, you can use nitrogen as process gas high pressure cutting. In that case, the cutting edge will not be oxidized. Thickness 10MM sheet, laser uses special plates and in the processing of oil can get better results on to the workpiece surface.
3, copper and brass
Two materials have high reflectivity and very good thermal conductivity. 1mm brass of thickness can be cut with nitrogen; 2mm copper thickness can be cut, process gases must be oxygen. Unless the system is installed on the "reflection-absorption" device to cut copper and brass. Otherwise reflections will destroy optical components.
Titanium sheet with argon and nitrogen as gas cutting. Other parameters can refer to the Nickel-chromium steel.
Despite the high reflectivity and thermal conductivity, 6mm thick laser cut aluminum can, depending on the type of alloy and laser capabilities. When oxygen cutting, cutting surface roughness and hardness. When using nitrogen, cutting a smooth surface. Pure aluminium because of its very difficult to cut, unless the system is installed on the "reflection-absorption" device when cutting aluminum. Otherwise reflections will destroy optical components.
