The principle of fiber laser cutting machine

1. Transmission of light

When the fiber laser generator generates light and transmits it to our laser head through the optical fiber, a certain amount of energy will be lost when the optical fiber is connected to the laser head, because the propagation of light is diffusive. This kind of light is also called Astigmatism, because light and light are mutually exclusive, so they can be infinitely close, but never intersect, its shape is like a waist.

When they are released by the fiber optic head, they take on a wavy shape.

2. Processing of Waveform Light
Waveform light is not conducive to collecting and concentrating energy, so a collimator is needed to process the wave light close to parallel light, which is certainly not absolute parallel light.

3. The role of focusing lens
The function of the focusing lens is to collect and concentrate the nearly parallel light to form a super-density light spot.

4. The role of protective lenses
When the fiber laser cutting machine is in use, a certain amount of metal dust and debris will be generated, and some metal dust and debris will be generated. If it enters the cutting head of the laser cutting machine, then it is necessary to protect the lens to isolate and protect it. (The protective lens is a consumable, and it damages 1 piece per month on average. Of course, the amount of loss depends on the intensity of the equipment and the scene, and the number is also different)

5. The role of the laser copper nozzle
After the laser passes through the protective lens, it is released through the laser copper nozzle. (Like protective lenses, laser copper nozzles are also consumables, and 2 pieces are damaged per month on average. Of course, they are still the same as lenses. The amount of loss varies according to the intensity of use of the equipment and the scene.)
