First, internal optics
Laser is a laser generator to release ultra-high density laser beam, through the light spot irradiation on the metal plate, high temperature instant melting or gasification cutting material, and then the use of high pressure gas, will melt melt and residue blown off, so as to achieve cutting, and then through X, Y, Z three axis linkage, so as to achieve cutting.
2, the generation of Fiber laser cutting machine
The laser is converted from electricity to light energy, and since the conversion between energy and energy cannot be 100%, part of the electrical energy is converted into light energy while the other part is converted into heat energy.
The current electro-optic conversion rate of fiber lasers is 25-35%. The better the performance of the laser, the higher the electro-optic conversion ratio. Of course, the relative, the greater the ratio of electro-optic conversion rate, the smaller the energy consumption, the lower the ratio of electro-optic conversion rate, the greater its energy consumption.
3. Heat generation
The laser is converted from electricity to light energy, and since the conversion between energy and energy cannot be 100%, part of the electrical energy is converted into light energy while the other part is converted into heat energy. (Energy will have heat) When this part of the heat generated, will stay in the laser, will damage the components of the laser.
So you need water to take that heat away, so you add a chiller.
Two, external optics
1. Transmission of light
When optical fiber laser generator produces light, through the optical fiber to transmit to our laser, the optical fiber when docking laser will produce certain energy loss, because light travels is invasive, the light also called astigmatism, because each other between the light and the light takes shape, so they can be infinitely close to, but they will never intersect, Its shape is like a waist.
When they are released by the fiber head, they take on a wavy shape.
2, waveform light processing
Wavy light is not conducive to collecting and concentrating energy, so collimating mirrors are needed to treat wavy light close to horizontal light, but not absolutely parallel light.
3. The role of focusing lens
The focus lens collects and concentrates light that has been processed to be nearly parallel, forming a super-dense spot of light.
4, the role of protective lens
When the fiber laser cutting machine in the use of the process, will produce a certain amount of metal dust and debris, a part of the metal dust and debris. It will enter the cutting head of the laser cutting machine, so it is necessary to protect the lens to isolate the protective effect. (Protective lenses are consumables, with 1 piece damaged on average every month. Of course, the amount of loss varies according to the intensity of use of equipment and different scenes.)
5, the role of laser copper mouth
After the laser passes through the protective lens, it is released through the laser copper nozzle. (Like the protection lens, laser copper nozzle is also a consumable, on average, every month to damage 2, of course, or the same as the lens, the number of loss according to the use of equipment intensity and different scenes, the number is different)
