Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source.
Fiber laser is a new type of fiber laser developed in the world. It outputs a laser beam with high energy density and gathers it on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized, and the spot is moved by the numerical control mechanical system. The automatic cutting is realized according to the irradiation position, with high speed and high precision.
CO2 Laser Cutting Machine
In the field of non-metallic laser marking, solid-state laser marking machines and gas laser marking machines (CO2 laser cutting machines) are common. Non-metallic laser cutting machines generally rely on laser power to drive the laser tube to emit light, and through the refraction of several reflectors, the light It is transmitted to the laser head, and then the focusing mirror installed on the laser head gathers the light into a point, and this point can reach a very high temperature, so that the material is instantly sublimated into gas, which is sucked away by the exhaust fan, so as to achieve the purpose of cutting .
The advantages of fiber laser cutting machine compared with CO2 laser cutting machine:
- Cutting ability: The fiber laser has the characteristics of short wavelength, which improves the absorption of the cutting material to the light beam, and is more suitable for transmission in the thin and soft optical fiber. Compared with the carbon dioxide laser conducted by mirror reflection, it is more flexible and easier to maintain. A 3KW fiber laser cutting machine is equivalent to a 4-5KW CO2 laser cutting machine in terms of cutting capacity and speed, which greatly reduces operating costs.
- Maintenance cost: The structure of carbon dioxide laser is relatively complex, and the maintenance cost in the later period is relatively high. The carbon dioxide gas laser system should be cleaned and maintained regularly, and the mirror should also be cleaned and calibrated regularly. Moreover, due to the purity of carbon dioxide gas, the resonator is also Maintenance is to be carried out regularly. In addition, the turbine that transports the laser gas also needs to be regularly maintained and renovated, so the later maintenance cost is very high and complicated. The fiber laser cutting machine is more convenient and environmentally friendly in the later maintenance.
With the development of fiber laser cutting machine and its own advantages, it has gradually replaced the market of carbon dioxide laser cutting machine. At present, carbon dioxide mainly cuts non-metallic materials, such as cloth, leather, acrylic, plastic, etc. With the development of high power fiber laser, it is gradually occupying the processing market of thick plates.
