In the early applications of fiber laser cutters, laser cutters required manual focus because there was no autofocus. This focusing method not only requires the technical level of the operator, but also has an impact on the precision and production efficiency of the product.

With the continuous improvement of production requirements, the new automatic focusing laser head comes out, the traditional manual focusing laser head is gradually eliminated, and the new automatic focusing laser head is widely used.

The punching focus of the manual focusing cutting head cannot be adjusted. The drilling focus is the same as the cutting focus. When cutting thick plates, the stamping energy is insufficient and the stamping time is long. The automatic focusing cutting head can adjust the stamping focus, increase the stamping energy by adjusting the focus, and improve the stamping speed of thick plate.

In terms of puncture time, automatic focusing is more than twice as fast as manual focusing, and the cutting effect is basically the same. The autofocus can reduce the overmelting phenomenon caused by the short overheating time of the material, which has obvious advantages. It can significantly improve production efficiency, greatly reduce the cutting and punching time of thick plate materials, and can process the workpiece of different materials and thicknesses. The machine can also quickly adjust the focus to the correct position.

So autofocus fiber laser cutters focus manually in most ways. With the development of technology, auto-focusing laser cutting machine is more practical.
