Optical fiber laser cutting machines are very common in enterprises that need to process metal, but those who have just come into contact with optical fiber cutting machines may be curious about why auxiliary gas should be added during laser cutting. It is difficult for novices to understand which gases need to be used and what role they will play in laser processing.

The following are the manufacturers of REDSAIL laser optical fiber laser cutting machine. They share with you the reasons and functions of adding auxiliary gas during laser cutting:

In fact, most of the auxiliary gases required for laser cutting are just ordinary air, oxygen and nitrogen. The purpose is to blow away the residue, so as to obtain better cutting effect. It is used to protect the lens while blowing off the slag with gas to prevent the slag from sticking to the lens. It is used to cut with nitrogen, which affects the cutting quality. It can effectively achieve the effect of cutting surface without burr and slag hanging, and refine the cutting; Use oxygen to cut. Oxygen helps to burn and react with materials, which can improve the cutting speed.

To sum up, laser cutting and laser drilling are basically the same in principle. The laser beam with high power density is focused and ejected at the designated position of the material to be processed. After the light is absorbed, the internal part of the material becomes hot. The melting or gasification of the material is due to the sharp rise in temperature. Proper auxiliary gas injection can not only protect the lens, but also blow away the processed slag. The incision is clean, the gap between the incisions is narrow, and the material has a small heating range.
