Laser head is the essential component of the laser cutting machine, in the early years of laser cutter, the laser cutting heads were manually focused. With more and higher demands of production in recent years, automatic focusing laser heads have gradually appeared.

So auto focus VS manual focus, which one is better?

1. Manual focus laser cutting head need not only requires technical skills for the operator, but also influences the product accuracy and production efficiency.

2. Because the penetration focus of the manual focusing cutting head cannot be adjusted, it is same as the cutting focus. When cutting thick plates, the penetration energy is insufficient and the penetrating time is long.
However, for auto focusing laser cutting head, the focal length can be adjusted. The penetration energy can be increased by adjusting the focal length, meanwhile, the penetration speed can be accelerated when cutting thick plates.

3. As far as penetrating time is concerned, the speed of auto focus is twice that of manual focus. The cutting effect is basically the same, but the auto focusing can reduce the plate over-melting phenomenon caused by short overheating time. 

4. The advantages of autofocus are outstanding. It can significantly improve production efficiency, greatly reduce the cutting time of thick plate materials. Moreover, when processing different metal materials and thickness, it is able to adjust the focus to a suitable position.

So in all, auto focusing laser cutting head is ahead of manual focusing in most aspects. With the development of science and technology, auto focusing laser cutting head will be more practical, and the processing effect will be more perfect.
