Each cutting process of the full-automatic coiling fiber laser cutting machine reflects the concentration of the mechanical craftsman. Their efforts enable the fiber laser cutting performance to be applied safely and efficiently. As we all know, the workpiece on the workbench weighs hundreds of kilograms, so it is not easy to adjust and move it. After using the automatic edge finding function of the fully automatic coiling fiber laser cutting machine, the time for adjusting the workpiece can be saved and the efficiency of the machine can be improved.
Fiber laser cutting machine
Solutions to common problems of automatic coiling fiber laser cutting machine:
1. Cutting and piercing technology
For each thermal cutting technology, only a few cases can be started from the edge of the plate. Generally, a small hole must be drilled in the plate. Previously, the punch was used on the laser stamping compound machine to punch a hole first, and then the laser was used to cut from the small hole.
2. Analysis of deformation of small hole (small diameter and plate thickness) in cutting
When processing small holes, pulse perforation is used instead of blasting perforation. As a result, the laser energy is too concentrated in a small area, and the non processing area is also burnt, thus causing hole deformation and affecting the processing quality. At this time, we should change the pulse perforation mode to the blasting perforation mode in the processing procedure to solve the problem. On the contrary, for laser cutting machine with small power, pulse perforation should be adopted to obtain better surface finish.
3. Solution to burr of workpiece during laser cutting of low carbon steel
According to the working and design principle of the full-automatic coiling fiber laser cutting machine, the following reasons are analyzed to be the main reasons for the burr of the processed parts: the upper and lower positions of the laser focus are incorrect, the focus position test needs to be conducted, and the adjustment is made according to the offset of the focus. The output power of the laser is insufficient, and it is necessary to check whether the laser generator works normally. If it is normal, Then observe whether the output value of the laser control button is correct and adjust it. If the linear speed of cutting is too slow, it is necessary to increase the linear speed during operation control.
