The reason why the protective lens of the laser printer has water mist

Auxiliary gas is essential in the cutting process of laser cutting machine! Among them, oxygen and nitrogen are commonly used. Of course, the higher the purity of the gas, the better the cutting quality will be. There are also many customers who want to save costs and use air cutting. However, there is always water mist on the protective lens during the cutting process, and the cutting quality is very poor. Why is this?

First of all, give Popularized by everyone, the role of auxiliary gas:

1. In order to blow away the residual waste, to achieve the best cutting effect.

2. Use gas to blow away the metal slag while protecting the lens to prevent the slag from sticking to the lens and affecting the cutting quality.

3. It can effectively achieve the effect of smooth cutting surface, no burrs and no slag, which belongs to fine cutting.

4. It can react with the material to increase the cutting speed. For example, the use of oxygen can achieve the effect of supporting combustion.

Therefore, in order to achieve a better cutting effect, the requirements for auxiliary gas are relatively high! Although air can be used as auxiliary gas, the air contains water and oil , If it is not treated, it will cause lens pollution, unstable cutting head, so that the cutting effect and quality are not up to standard, etc. Therefore, when using air cutting, it is necessary to equip the fiber laser cutting machine with a cold dryer, which solves this problem very well. The refrigeration dryer can force the compressed air to cool below the required dew point temperature, thereby condensing a large amount of water vapor and oil mist contained in it into droplets, which are separated from the gas and liquid and discharged from the machine through the drain to dry the compressed air.
