As the temperature rises in summer, the working pressure of the cooling system of the laser cutting machine increases. It is recommended to maintain the pressure of the cooler before the high temperature comes. The equipment pressure of different manufacturers is also different
Make sure that the laser tube is full of circulating water before the machine works. The quality and temperature of the circulating water directly affect the service life of the laser tube. Therefore, the circulating water shall be replaced regularly and the water tank shall be cleaned. This is better done once a week.
There will be some mirrors and focus mirrors on the machine. The laser is reflected and focused by these lenses and then emitted from the laser hair.
The lens is easy to be stained with dust or other pollutants, causing laser loss of the laser cutting machine or lens damage. So clean the lenses every day. Pay attention to:
The lens shall be wiped gently without damaging the surface coating; The wiping process shall be handled with care to prevent falling; When installing the focusing mirror, be sure to keep the concave side downward.
Due to the high temperature in summer, the deterioration rate of cooling water will also be accelerated. It is recommended that users of laser cutting machines use distilled water or pure water, and regularly clean the scale, so as not to cause scaling in the laser pipe and affect the laser power. Different types of laser cutting machines have different methods for cleaning scale, and they need to be operated under the guidance of the manufacturer.
Laser cutting machine In the process of cutting, auxiliary gas is essential. We usually use oxygen and nitrogen. Of course, the higher the purity of the gas, the better the cutting quality. There are also many customers who want to save costs and use air to cut. However, there is always water mist on the protective lens during the cutting process, and the cutting quality is very poor. So why?
Function of auxiliary gas
1. In order to blow away the residual waste residue and achieve better cutting effect.
2. The use of gas to blow away the metal slag also protects the lens, preventing the slag from sticking to the lens, thus affecting the cutting quality.
3. It can effectively achieve the effect of smooth and clean cutting surface without burr and slag, which belongs to precision cutting.
4. It can react with materials and increase the cutting speed. For example, using oxygen can achieve the effect of combustion supporting.
Therefore, in order to achieve better cutting effect of laser cutting machine, the requirements for auxiliary gas will be higher. Although air can be used as auxiliary gas, it contains water and oil. If it is not treated, the lens will be polluted, and the cutting head will be unstable, so that the cutting effect and quality cannot meet the standard.
