Problems and solutions of fiber laser cutting head
 
Fiber laser cutting machine is very popular in the metal manufacturing industry, where the laser cutting head plays a very important role in the machine. Laser cutting heads are highly precise and expensive. If the maintenance of the fiber laser cutting machine is not in place, various problems will occur. This article introduces some common problems and solutions for fiber laser cutting heads to help you avoid laser head failures.
 
QBH localized fever
When the QBH is locally heated, check the collimation upper protective mirror first, and replace it in time if it is damaged. If there is no problem with the protective lens, you need to check the status of the collimator lens and the fiber end.
 
The cutting head nozzle is hot or the focusing cavity is hot
First check the goggles for obvious burn marks, or moisture and oil stains on the goggles. If the protective mirror has a burning point, it needs to be replaced in time. If there is water vapor or oil pollution, it is necessary to check the filter element of the air compressor, replace the air compressor filter element or repair the air dryer. If there is no problem with the protective glasses, it is necessary to check the condition of the focusing lens and the circulation of the cooling water.
 
The focus position of the laser cutting head automatically changes
When cutting metal, the focusing part changes automatically. In general, the sealing ring of the protective mirror may be damaged, and the air pressure enters the focusing cavity, causing the lens to move up, and the sealing ring of the protective mirror needs to be replaced. If the replacement of the protective lens sealing ring is invalid, it is necessary to confirm whether the thickness of the protective lens used is deviated. If the thickness of the protective lens is too thin, the sealing ring will also be unsealed.
 
The above points are the common problems and solutions of fiber laser cutting heads. The fiber laser cutting machines produced by the ACCTEK factory will be equipped with a protective shell on the surface of the laser head, which can effectively prevent dust from entering the laser head or cause damage, thereby better protecting the laser head.
