The principle of fiber laser cutting machine: internal optics and external optics

Fiber laser cutting machine has a wide range of applications and can be used for fast and efficient processing and production. So how does the fiber laser cutting machine use laser to cut? How does the laser come into being and what is its principle?Fiber laser cutting machine is divided into internal optics and external optics.1. optics1. Cutting principle
Laser is a laser generator to release a super density of laser beam, through the spot irradiation on the metal plate, high temperature instant melting or gasification cutting materials, and then use high pressure gas, the melting of the melt and residue blown off, so as to achieve the cutting seam, and then through the X, Y, Z three-axis linkage, so as to achieve cutting.
2, the generation of laser
Laser is converted from electrical energy to light energy, because the conversion between energy and energy cannot be 100%, so while part of electrical energy is converted into light energy, the other part becomes heat energy.
At present, the electro-optical conversion rate of fiber lasers is 25%-35%. The better the performance of the laser, the higher the proportion of electro-optical conversion rate. Of course, the larger the proportion of electro-optical conversion rate, the smaller the energy consumption, and the lower the proportion of electro-optical conversion rate, the greater its energy consumption.3. The generation of heatLaser is converted from electrical energy to light energy, because the conversion between energy and energy cannot be 100%, so while part of electrical energy is converted into light energy, the other part becomes heat energy. (There is energy, there will be heat) When this part of the heat energy is generated, it will stay in the laser and damage the components inside the laser.Therefore, it is necessary to take away this part of the heat through the water, so it is necessary to add a cold water machine.2. external optics1. Transmission of light
When the fiber laser generator generates light and transmits it to our laser head through the fiber, the fiber will produce a certain energy loss when docking 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 they will never intersect, and its shape is like a waist shape.

When they are released by the fiber head, the shape they take is wavy.

2. Processing of waveform light
Waveform light is not conducive to collecting and concentrating energy, so a collimating lens is needed to process the waveform light close to parallel light, of course, it is not absolutely parallel light.
3, the role of focusing mirror

3, the role of focusing mirror
The function of the focusing mirror is to collect and gather the light that has been processed into nearly parallel light to form a super-dense spot.

4. The role of protecting lenses
When the fiber laser cutting machine is in use, it will produce a certain amount of metal dust and debris, and some of the metal dust and debris. Will enter the cutting head of the laser cutting machine, then you need to protect the lens to do the role of isolation protection. (Protective lenses are consumables. On average, one piece is damaged every month. Of course, the number of losses varies according to the intensity of the equipment and the scene.)

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