Why do laser cutting machines need auxiliary gas?
The role of laser cutting machine using auxiliary gas is mainly as follows: 1) Most of them use air, or oxygen, and nitrogen. The first purpose is to blow away the residual slag to achieve the best cutting effect. 2) While using the gas to chase away the metal slag, protect the lens and prevent the slag from sticking to the lens, affecting the cutting quality. 3) Using nitrogen cutting, it can effectively achieve the effect of smooth and clean cutting surface, no burr and no dross. 4) Using oxygen cutting, oxygen can support combustion and react with materials to increase cutting speed.
