What is fiber laser cutting machine?

Fiber laser cutting machine is a laser cutting machine using fiber laser generator as a light source.

Fiber laser is a new international development of a new type of fiber laser output high energy density laser beam, and gathered on the surface of the workpiece, so that the workpiece is irradiated by ultra-fine focus spot instant melting and gasification, through the CNC mechanical system to move the spot irradiation position to achieve automatic cutting. Compared with the large volume of gas lasers and solid lasers, it has obvious advantages, and has gradually developed into an important candidate in high-precision laser processing, liDAR systems, space technology, laser medicine and other fields.

Fiber laser cutting machine It can do plane cutting, also can do oblique cutting processing, and the edge is neat and smooth, suitable for high-precision cutting processing such as metal plate, while coupled with a mechanical arm can be three-dimensional cutting instead of the original imported five-axis laser. Compared with ordinary carbon dioxide laser cutting machine, it saves space and gas consumption, has high photoelectric conversion rate, is a new product of energy saving and environmental protection, and is also one of the world's leading technology products.

1. The advantages of fiber laser cutting machine than CO2 laser cutting machine:

(1) Excellent beam quality: smaller focus spot, finer cutting lines, higher working efficiency, better processing quality;

(2) Extremely high cutting speed: twice the same power CO2 laser cutting machine;

(3) High stability: The use of the world's top imported fiber lasers, stable performance, the service life of key components can reach 100,000 hours;

(4) Extremely high electro-optic conversion efficiency: optical conversion efficiency of fiber laser cutting machine is about 30%, which is 3 times higher than CO2 laser cutting machine, energy saving and environmental protection;

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

(6) Very low maintenance cost: no laser working gas; Optical fiber transmission, no need for reflective lenses; Can save a lot of maintenance costs;

(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 carbon dioxide laser cutting machine, the cutting range of optical fiber is relatively narrow. Because of the wavelength, it can only cut metal materials, and non-metals are not easily absorbed by it, thus affecting its cutting range.

2. 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: Optical fiber laser cutting machine photoelectric conversion efficiency is about 10 times that of YAG

The price of the corresponding fiber laser is high, so the price of the fiber laser cutting machine is much higher than the YAG laser cutting machine, but it is much lower than the carbon dioxide laser cutting machine. But it does have the highest sex ratio of the three.
