Main points for using fiber laser cutting machine

Nowaday, fiber laser cutting became a popular trend for various industries need metal cutting. More and more factories have their own machines for metal cutting. But since the laser cutting working process is a new craft, some customers still can not operate the machine very well. Actually, if you do know the principle of laser and machine. Then there is not a problem. So today, I will give you some useful tips. It might help you to better understanding how to use that.


Carbon Steel.

Carbon Steel is not a high-reflection material. It is not like aluminum or brass. This material is the most suitable material for fiber laser cutting. For the cutting effect, any machines you can find in the market are able to cut carbon steel with a perfect effect.  The application of carbon steel is more and more extensive. The maximum thickness of carbon steel plate can be cut by modern 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.
