The perforation focus of the manual focusing cutting head cannot be adjusted, because the focus during perforation can only be the focus of cutting, and the energy of perforation focusing is insufficient, so the perforation is slow, which is reflected in the perforation of thick plates.
The perforation focus of the automatic focusing cutting head can be adjusted. During perforation, the focus can be adjusted to change the focus energy during perforation, so the perforation speed is fast and the perforation time of thick plates can be effectively reduced . Autofocus functions available to automate not only the target device, but also significantly improve the processing efficiency of the fiber laser cutting machines , machining of different materials, different thickness of the workpiece, the machine can quickly adjust the focus automatically to the most appropriate location.
Autofocus than manual focus cutting head of the cutting head of the plank through the hole fast time 2 times, it is possible to reduce the sheet to overheating caused by burnt phenomenon.
