Laser cutting machine can be divided into fiber laser cutting machine, CO2 laser cutting machine and YAG laser cutting machine.Today I want to compare the first two.
Fiber laser cutting machine is a laser cutting machine which USES fiber laser generator as light source.Fiber laser is a new type of fiber laser which produces laser beam with high energy density and concentrates on the surface of the workpiece, so that the area irradiated by the ultra-fine focus spot on the workpiece is melted and gasified instantly. The automatic cutting can be realized by moving the spot irradiated position by the numerical control mechanical system.
Non-metallic laser cutting machine usually driven by laser power laser tube, through the reflection of a few mirrors, make the light transmission to the laser head, again by the focus lens laser head installation will be pooled into a little light, and this can achieve high temperature, thus the sublimation in the material as a gas, by sucking exhauster, thus achieve the goal of cutting.The main gas filled in the laser tube used by the general laser cutting machine is CO2, so this kind of laser tube becomes CO2 laser tube, and the laser cutting machine using this kind of laser tube is called CO2 laser cutting machine.
Compared with CO2 laser cutting machine, fiber laser cutting machine has the following advantages
1. Excellent beam quality:
focus light spot is smaller, cutting line is more precise, the work efficiency is higher, the processing quality is better.
2. High stability:
the use of the world's top imported fiber laser, stable performance, the key components of the service life of up to 100 thousand hours.
3. Super flexible light guide effect:
small size, compact structure, easy to flexible processing requirements.
4. Extremely high cutting speed:
2 times of the same power CO2 laser cutting machine.
5. High electro-optical conversion efficiency:
fiber laser cutting machine photoelectric conversion efficiency of about 30%, CO2 laser cutting machine is three times higher, energy saving and environmental protection.
6. The product operation and maintenance is convenient:
the optical fiber transmission, no need to adjust the light path.
7. Extremely low cost of use:
the power consumption of the whole machine is only 20-30% of the same kind of CO2 laser cutting machine.
8. Extremely low maintenance cost:
no laser working gas, optical fiber transmission, no reflection lens, can save a lot of maintenance costs.
Of course, compared with the CO2 laser cutting machine, the cutting range of the fiber laser is relatively narrow. Because of the wavelength of the reason, it can only cut metal materials, non metal is not easy to be absorbed, thereby affecting the cutting range.
