How to deal with laser cutting machines protective lens pollution and laser cutting machines heating problems

Laser cutting machines will encounter some problems during the cutting process, for example, the protective mirror will be polluted quickly, and the cutting nozzle will heat up when laser cutting machines cut carbon steel plates.

G-CUT LASER focuses on low and medium power fiber laser cutting machines, high power fiber laser cutting machines, ultra-high power fiber laser cutting machine sales and service, has many years of laser cutting equipment research and development, manufacturing experience. Teach you how to deal with these situations with ease.

First of all, the types of pollutants must be determined. Pollutants usually include waste residue, oil stains, dust, water mist and mixtures.1. Waste residue: mainly due to improper parameter setting of laser cutting machines, cutting waste residue is splashed onto the lens. It is suggested that you can solve it by adjusting the cutting or perforating process parameters, such as follow-up height, cutting air pressure, laser pulse parameters, etc.

2. Oil or dust: the auxiliary gas itself or the gas circulation pipeline is polluted. It can be prevented and controlled by adding a filter device, oil filter or dust filter3. Water mist: generally caused by excessive temperature difference. The ambient temperature is too high, the cutting gas temperature is too low, and the protective mirror condenses in the ambient temperature. It can be solved by adjusting the temperature of the two to make them similar.How to deal with the heating of the cutting nozzle of laser cutting machines cutting carbon steel plate? You can try the following suggestion1. The cutting gas flow rate is small, which cannot fully cool the copper nozzle. High-pressure nitrogen can be used as auxiliary gas, and high-pressure nitrogen has a good cooling effect.

2. The copper nozzle is not used to cool the gas. Adapting the copper nozzle cooling gas can reduce the heat generation of the copper nozzle.

3. High-focus cutting, the laser is easy to hit the small nozzle, making the nozzle overheat. The focus must be adjusted or the nozzle diameter must be increased while the nozzle is not hot.

4. When carbon steel is cut, an oxidation reaction occurs and a large amount of heat is generated. This situation cannot be avoided, and the distance between the nozzle and the material can be adjusted appropriately.
