The Reason Why The Protection Lens Of Laser Cutting Machine Is Easy To Burn
The protective lens is the most easily damaged component during the working process of a laser cutting machine. If you find that your protective lenses are burning out regularly and frequently, then you need to pay attention to what the problem is. Let's understand the possible causes of burnt out protective lenses.
1. Air cold dryer problem
If the power to the air cooler is not turned on, or if the automatic drain time of the air cooler is not set properly, or even if there is a problem with the air cooler itself, the air coming out may contain moisture. In addition, the filter element of the cold dryer needs to be replaced regularly and the water inside the tank needs to be drained regularly. In order to make sure that the gas comes out is lossless, it is a good idea to add an adsorption dryer behind the cold dryer.
2. Parameter setting problems
If the perforation cut or perforation dwell time is not set, or if the perforation delay time is set too fast, it may lead to lens burns. In addition, if the parameter is not set properly, it may lead to burst hole or not cut through.
3. Cutting head problems
You need to check whether the optical path of the cutting head has been shifted, whether there is any damage to the lens, and whether the nozzle aperture is too large. If you find any of these problems, you need to adjust and repair them in time.
4. Air line problem
If there is dust or oil inside the air line, they will keep building up inside and may cause the protective lens to burn out.
5. Time delay problem
The air exchange delay should be adjusted to between 200~500, if the delay is too short, the laser may come out first and then the air, which is easy to burn the protective lenses. Accordingly, it is also necessary to adjust the length of stopping the light and blowing air.
6. Perforation energy
If the perforation time is too extreme to perforate and burst, we need to adjust the appropriate perforation energy and increase the perforation time.
7. Gas source problem
If the gas source is not turned on or the gas exhaustion is not found in time, and still cutting for a long time, this may also lead to serious burnout or burnout of the protective lens.
8. Laser polarization problem
Serious laser polarization may lead to burn cutting nozzle reflection, which will burn the protective lens.
These are some of the possible reasons why the protective lenses will always burn out easily when working with fiber laser cutting machines. Hopefully, this information can help you solve the problem better.
