Any equipment will have aging problems after long-term use, and fiber laser cutting machine is no exception. Among them, the laser in the metal laser cutting machine is the most easily aged component, so we also need to pay attention to it during normal use. What are the vulnerable parts of the laser cutting machine? The following editor will share with you.

Reasons for the power attenuation of the metal laser cutting machine:

1. Problems with the laser itself.

Metal laser cutting machines require regular maintenance and maintenance of the external optical path of the laser. In fact, after the laser has been working for a period of time, the power drop is inevitable. Of course, when the power drops to affect production, the laser generator needs to be maintained. After the maintenance is completed, the cutting ability will be restored to the level at the factory.

2. The environment and conditions of the factory also have a great impact on the power of the fiber laser cutting machine.

Such as the quality of compressed air (mainly oil filtration, dryness, and dust). The current production of dust and smoke is high, and some users put the spray painting operation near the fiber laser cutting machine, which will affect the cutting quality and cutting ability of the laser cutting machine. So these should be paid attention to during the processing. If necessary, you can add a dedicated dust removal device.

What are the consumable parts of the fiber laser cutting machine?

There are many kinds of consumable parts for fiber laser cutting machines. Today, I will mainly introduce the protective lenses in laser cutting machines.

As the name suggests, the protective lens is used to prevent dust and slag splashing from damaging the focusing lens. In addition to being used in laser cutting machines, it is also necessary in other laser equipment, including laser marking, laser welding and laser engraving. It can be seen that the application market for protective lenses is very large.

The prices of protective lenses on the market vary greatly, ranging from tens of yuan to hundreds of yuan, and the quality is also different. Of course, it is not uncommon to sell inferior products as good ones. If the lens is not selected properly, it will cause large laser loss, frequent damage to the protective lens, unstable product quality, and cause serious losses to the company. Therefore, choosing a suitable protective lens is a very important thing.

There are three steps to choose the protective lens of the fiber laser cutting machine:

1. Match the appearance and size, which is easy to understand;

2. Material, according to different laser powers, consider the use cost. In the actual application process, professional manufacturers divide these two types of materials into multiple grades, and customers can choose the corresponding specifications according to actual needs;

3. Coating, laser anti-reflection film, different coating technical parameters are used according to the use environment.

Although the protective lens of the fiber laser cutting machine is a consumable part, in order to improve its utilization rate and reduce production costs, the protective lens can be cleaned regularly to achieve the purpose of reuse.
