What are the matters that need to be paid attention to during the use of laser cutting head
2024-11-07
With the promotion and application of laser technology, the domestic laser industry has gradually expanded, and the market scale has gradually grown, especially the artistic processing of enterprise products has been widely used. At present, the application of laser cutting has developed into an emerging industry and one of the key technical equipment for transforming traditional manufacturing industry. After a long period of accumulation, the laser cutting head has been continuously updated and mature. The key point affecting the laser cutting process is the laser head. The laser head and other modules are combined and applied to different fields, such as laser marking, laser welding, laser cutting, laser cladding, etc. So what precautions should we take when using the laser cutting head?
1. Avoid condensation caused by excessive temperature difference
Please set the water cooling temperature according to the water cooling temperature comparison table specified by the laser head manufacturer, pay attention to the temperature changes at the production site, and adjust the water cooling temperature in time. Condensation will occur when the cooling water temperature is lower than the condensation temperature. During the process of plugging and unplugging the optical fiber, the water vapor brought into the optical fiber.
2. When removing the protective lens drawer, please seal the cutting head in time
When checking or replacing the protective lens at the work site, you need to remove the protective lens drawer. Please seal the cutting head in time to prevent contaminants from entering the inside of the cutting head and causing light path pollution. Note: The cleanliness of the collimator lens protective lens should be tested only after plugging and unplugging the optical fiber. In other cases, it is not necessary to open the collimator lens protective lens for testing.
3. Do not continue to use the protective lens when there is a burn point
When the protective lens has a burn point, the lens needs to be replaced immediately. After the coating is damaged, it will deflect the laser. If it is scattered to the inner wall of the cutting head cavity, the temperature will rise, and it will also affect the surface of other lenses, causing greater losses.
4. Ensure the cleanliness of the cutting gas
Before using the cutting gas, you first need to test the cleanliness of the gas and the gas pipeline, such as residues, water vapor, oil and other contaminants. If the gas contains the above impurities, the risk of contamination of the protective lens will increase, and the frequency of replacing the protective lens will also increase. In severe cases, the gas path will be blocked, resulting in a decrease in cutting effect.
5. Turn on the automatic cleaning function
When using the laser head with automatic cleaning function of Raytools, turn on the automatic cleaning function regularly for about 5 minutes to remove the dust on the lens and extend the service life of the laser head.
