1kw fiber laser cutting machine 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 1kw fiber laser cutting machine:
1. In order to blow away the residual residue, to achieve the best 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, due to the air contains water and oil, if not treated, will cause lens pollution,
cutting head instability, so that the cutting effect and quality is not up to standard.
Therefore, in the use of air cutting, the need for fiber laser cutting machine equipped with cold drying machine,
so it is a good solution to this problem. The cold drying machine can force the compressed
air to cool to the required dew point temperature below,
so as to condense a large amount of water vapor and oil mist into liquid droplets, through gas-liquid separation,
discharged from the drainage machine, so that the compressed air is dry.
