The technique tips of cutting metal by fiber laser cutting machine

Carbon steel
As carbon steel does not reflect the light strongly, absorbs the beam very well, the carbon steel is most suitable for the G-CUT laser cutting machine processing of all metal materials, is also the best effect. Therefore, the laser cutting machine for carbon steel has an unshakable position in the process of carbon steel.
The application of carbon steel is more and more extensive. The maximum thickness of carbon steel plate can be cut by modern fiber laser cutting machine up to 20MM. the cutting seam of carbon steel can be controlled in the range of satisfactory width by using oxidation melting cutting mechanism, and the cutting seam of thin plate can be narrowed to about 0.1mm.

Stainless steel
Laser cutting of stainless steel, using the energy released by a laser beam to the surface of a steel plate to melt and vaporize the stainless steel. Laser cutting of stainless steel is a fast and effective method for manufacturing of stainless steel sheet as main component. Cutting speed, laser power, air pressure and so on are the most important technological parameters affecting the cutting quality of stainless steel. Compared with low carbon steel, stainless steel cutting requires higher laser power and higher oxygen pressure. But the stainless steel cutting achieves satisfactory cutting effect, it is difficult to obtain the completely non-stick slag cutting seam. In general, high pressure nitrogen and laser beam coaxial injection are used to blow away molten metal so that no oxide is formed on the cutting surface. This is a good method, but more expensive than conventional oxygen cutting. One alternative to pure nitrogen is to use filtered compressed air in the workshop, which consists of 78% nitrogen.
