Fiber-optic laser cutting machine is a laser cutting machine using fiber-optic laser generator as the light source. The working principle is as follows: the laser cutting machine is concentrated 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 is realized by moving the spot irradiated position by the numerical control mechanical system.Compared with the bulky gas laser and solid laser, it has developed into an important candidate in the fields of high-precision laser processing, lidar system, space technology and laser medicine.

Fiber laser cutting machine it can do both plane cutting, also can do bevel cutting processing, and the edge is neat, smooth, suitable for metal plate and other high-precision cutting processing, at the same time, coupled with a mechanical arm can carry out three-dimensional cutting instead of the original imported five axis laser.Compared with the common carbon dioxide laser cutting machine more save space and gas consumption, photoelectric conversion rate is high, is a new product of energy conservation and environmental protection, is also one of the world's leading technology products.

Advantages of fiber laser cutting machine over CO2 laser cutting machine:

1) excellent beam quality: smaller focusing spot, finer cutting line, higher working efficiency and better processing quality;

2) extremely high cutting speed: it is twice as fast as the CO2 laser cutting machine of the same power;

3) extremely high stability: the world's top imported fiber laser has stable performance and the service life of key components can reach 100,000 hours;

4) extremely high electro-optical conversion efficiency: the photoelectric conversion efficiency of optical fiber laser cutting machine is about 30%, three times higher than CO2 laser cutting machine, energy saving and environmental protection;

5) extremely low use cost: the power consumption of the whole machine is only 20-30% of that of the similar CO2 laser cutting machine;

6) extremely low maintenance cost: no laser working gas;Fiber optic transmission, no need for reflective lenses;Substantial maintenance cost savings;

7) easy operation and maintenance: optical fiber transmission, no need to adjust the optical path;

8) super flexible light guiding effect: small size, compact structure, easy to flexible processing requirements.

Of course, compared with the carbon dioxide laser cutting machine, the cutting range of optical fiber is relatively narrow.Because of the wavelength, it can only cut metal materials, non-metal is not easy to be absorbed, thus affecting its cutting range.

Advantages compared with YAG laser cutting machine:

1) cutting speed: the speed of fiber laser cutting machine is 4-5 times that of YAG, which is suitable for mass processing and production

2) use cost: the use cost of fiber laser cutting machine is less than that of YAG solid laser cutting

3) photoelectric conversion efficiency: the photoelectric conversion efficiency of optical fiber laser cutting machine is about 10 times that of YAG


Main features:

(1) optical fiber laser has high electric-to-optical conversion efficiency, which is more than 30%. Low-power optical fiber laser does not need to be equipped with chiller, and adopts air cooling, which can greatly save the power consumption during work, save the operation cost and achieve the highest production efficiency.

(2) the operation of the laser only requires electric energy, no extra gas is needed to produce the laser, and it has the lowest operation and maintenance costs;

(3) the fiber laser adopts the design of semiconductor modularization and redundancy. There is no optical lens in the resonant cavity, and no start-up time is needed. It has the advantages of free adjustment, free maintenance and high stability, which reduces the cost of accessories and maintenance time, which is incomparable to the traditional laser.

(4) the output wavelength of the fiber laser is 1.064 micron, 1/10 of the wavelength of CO2. The output beam is of good quality and high power density, which is very conducive to the absorption of metal materials. It has excellent cutting and welding ability, thus making the processing cost lowest.

(5) the whole machine optical route optical fiber transmission, does not need the complex mirror and other light guide system, the optical path is simple, the structure is stable, the external optical path maintenance free;

(6) there are protective lenses in the cutting head, so that precious consumables such as focusing lens are rarely consumed;

(7) light is exported through optical fiber, making the design of mechanical system very simple and easy to integrate with robot or multi-dimensional workbench;

(8) after the laser is equipped with a light gate, it can be divided into multiple machines by optical fiber and work at the same time. It is easy to expand the function and easy to upgrade.

(9) optical fiber laser is small in size, light in weight, movable in working position, and occupies a small area;
