The laser cutting equipment will be checked irregularly. The damaged equipment of parts can be directly and obviously displayed, but it is difficult to judge whether the laser cutting head is within the normal calibration level. How to judge whether the laser cutting equipment is calibrated normally?
1. Stability
As a precise part of the laser cutting equipment, the fiber laser has stable performance, and the service life of the part can reach 100000 hours or more, so the output is very stable without deviation in the working process. When the laser is not very stable in a certain period of time and there is a small problem in the output, it can be judged with a high probability that it is not within the calibration level, and then it can be overhauled.
2. Perpendicularity
For laser cutting equipment, after programming, the cutting head will complete the cutting task according to the program instructions, so there will be no deviation in perpendicularity. The perpendicularity of the cutting edge is very important. If the cutting head is not calibrated, the cutting edge will deviate from the place specified in the program instructions, so the cutting prototype does not meet the actual needs.
3. Width of slit
The laser beam of the cutter is focused into a very small light spot, so that the focus reaches a very high power density. The material is quickly heated to the degree of gasification, and the hole is formed by evaporation. With the relative linear movement of the beam and the material, the hole continuously forms a slit with a very narrow width.
4. Coaxiality judgment
During the calibration of the laser cutting equipment, if the air flow center is different from the beam center, the spark splashes unevenly in all directions when cutting carbon steel plate holes, at this time, it is generally corrected by translating the air flow center, that is, translating the nozzle, and then conducting the carbon steel plate hole drilling test to observe whether the spark splashes evenly. If it is not uniform, adjust it again, The coaxiality between the air flow center and the beam center must be adjusted to an ideal state.
