Solutions to common problems of fully automatic coiling fiber laser cutting machine:
1. Cutting and piercing technology
For each kind of thermal cutting technology, only a few cases can start from the edge of the board. Generally, a small hole must be punched in the board. Previously, a punch was used on the laser stamping compound machine to punch a hole first, and then the laser cut from the small hole.
2. Analysis of deformation of cutting small holes (small diameter and plate thickness)
When machining small holes, pulse perforation is used instead of blasting perforation. As a result, the laser energy is too concentrated in a small area, which makes the non machining area scorched, resulting in 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 program to solve it. For the laser cutting machine with small power, on the contrary, pulse perforation should be adopted in the small hole processing to obtain a better surface finish.
3. Solution of burr on workpiece when laser cutting 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 machined parts: the upper and lower positions of the laser focus are incorrect, so the focus position test needs to be done, and it is adjusted according to the offset of the focus. The output power of the laser is not enough, so it is necessary to check whether the laser generator works normally. If it works normally, Observe whether the output value of the laser control button is correct and adjust it. The linear speed of cutting is too slow, so it is necessary to increase the linear speed during operation control.
