2000w fiber laser machine for metal cutting in the cutting process, auxiliary gas is essential! We commonly use oxygen and nitrogen, of course, the higher the purity of gas
cutting quality will be better. There are also many customers who want to save cost by using air cutting,
but there is always water mist on the protective lens in the cutting process, and the cutting quality is very poor.
Why is this? First of all, let's popularize the role of auxiliary gas:
1. In order to blow away the residual residue, to achieve *1 good cutting effect
2. Use gas to blow away the metal slag and protect the lens to avoid the slag sticking to the lens and affecting the cutting quality.
3 can effectively achieve the cutting surface smooth, no burr no hanging slag effect, belongs to the fine cutting.
4. Can react with the material to increase the cutting speed, such as the use of oxygen can achieve the effect of combustion.
Therefore, in order to achieve better cutting effect, the requirements of the auxiliary gas are relatively high!
Although air can be used as an auxiliary gas, but because the air contains water and oil, if not through
Exciting processing, precision fiber laser cutting machine which good, will cause lens pollution, cutting 1 unstable,
so that the cutting effect and quality is not up to standard. Therefore, when using air cutting, the head is needed
