Why does the laser cutting machine protect the lens from water mist?

Why does the laser cutting machine protect the lens from water mist.The auxiliary gas is essential in the cutting process of the fiber laser cutting machine!

Oxygen and nitrogen are commonly used. Of course, the higher the purity of the gas, the better the quality of the cut.

There are many customers who want to save costs and use air cutting, but in the cutting process, the lens is always protected from water mist.

And the cutting quality is very poor. Why? XT LASER talks about the reason why fiber laser cutting machines protect lenses from water mist.

First of all, to popularize the role of auxiliary gas:
1. In order to blow off the residue, the best cutting effect is achieved.

2. Use gas to blow metal slag while protecting the lens to avoid sticking on the lens and affect the cutting quality.

3. It can effectively achieve the smooth cutting surface, no burr, no slag hanging effect, belonging to fine cutting.

4. It can react with materials to increase the cutting speed. For example, oxygen can be used to achieve the burning effect.

To sum up

Therefore, in order to achieve a better cutting effect, the requirements of the auxiliary gas are relatively high!

Although air can be used as an auxiliary gas, because the air contains moisture and oil.

If it is not treated, it will cause lens pollution, the cutting head is unstable, and the cutting effect and quality will not reach the standard.

Therefore, when using air cutting, a fiber laser cutting machine equipped with a cold dryer is required, which will solve this problem well.

The cold and dry compressed air can be cooled to the dew point temperature requirement, which contains a large amount of water vapor, and the oil mist condenses into droplets, which are separated from the water machine by gas-liquid separation, and the compressed air is dried.
