How to solve the problem of large slit of optical fiber laser cutting machine? The optical fiber laser cutting machine has become an indispensable tool in sheet metal processing. The advantages of high cutting accuracy and high efficiency make the optical fiber laser cutting machine quickly occupy the market. Usually, when we use the laser cutting machine for processing, there are occasionally large cutting gaps, which cause the cutting accuracy of the workpiece to decline and can not meet the production requirements. What should we do if we encounter such a problem?

01. Check whether there is a problem with the focal length, especially pay attention to the change of the focal length after the lens is cleaned and replaced with a new lens, and adjust the correct focal length value!

02. Check whether the lens is damaged or dirty, because this situation will cause laser scattering, leading to laser beam thickening. Replace or clean the lens.

03. The laser tube is also a factor that cannot be ignored. Check the quality of the light spot at the laser tube's optical outlet. If there are bright spots or light spots that are not round or hollow, find the support point of the laser tube and see if the direction is appropriate! The solution is to adjust the support, rotate the direction and replace the laser tube.

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

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

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

3) Extremely high stability: the world's top imported fiber laser is used, with stable performance, and the service life of key components can reach 100000 hours;

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

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

6) Very low maintenance cost: no laser working gas; Optical fiber transmission without reflector; It can save a lot of maintenance costs;

7) The product is easy to operate and maintain: optical fiber transmission, no need to adjust the optical path;

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