When we use the laser cutting machine, there is water mist on the protective lens during the cutting process, resulting in poor cutting quality. Normally, there should be no foreign matter on the lens of the cutting head of the laser cutting machine, let alone water mist.
When the laser cutting machine is processing, auxiliary gas is necessary! There are three kinds of auxiliary gases we use most, namely oxygen, nitrogen and air. Of course, the higher the purity of the gas, the better the cutting quality will be. When conditions permit, air assisted cutting by laser cutting machine is the lowest cost way. However, there will often be water mist on the protective lens in the process of using air assisted cutting, which not only makes the cutting speed very slow, but also makes the cutting quality very poor. Why is there water mist on the protective lens of laser cutting machine
First of all, let's popularize the role of auxiliary gas:
1. In order to blow away the residual slag and achieve the best cutting effect.
2. Protect the lens while blowing away the metal slag with gas to avoid the slag sticking to the lens and affecting the cutting quality.
3. It can effectively achieve the effect of smooth cutting surface, no burr and slag, which belongs to fine cutting.
4. It can react with materials and increase the cutting speed. For example, using oxygen can achieve the effect of combustion support.
