Advantages of autofocus laser head

The first thing we need to know is what is focus control? Laser cutting machine in cutting different materials and different thickness of the plate. In order to achieve a better cutting effect, the focus of the laser beam will set in different places.

In laser cutting applications, the main way to focus is to rely on manual to complete. Now with the development of laser technology, this manual focusing method has been gradually eliminated. Most factory to use Auto-focusing function. For example, the full range of high-energy laser cutting machine equip with a fully automatic focusing function. Then the cutting head raise, the focus position is high. The cutting head lowered, and the focus position is low.

The base of laser cutting head is a nozzle. During the cutting process, the distance between the nozzle and the workpiece (nozzle height) is about 0.5 ~ 1.5 mm. The nozzle height is the same. So can not raise and lower to focus the cutting head (otherwise can not complete the cutting process) . The focal length of the focusing lens is immutable, so you can not expect to change the focal length to focus. If you change the position of the focusing Lens, you can change the focus position: If the focusing lens goes down, the focus will go down, if the focusing lens goes up, the focus will go up. It is a way of focusing, as if. The auto-focusing can realize by using a motor to drive the focusing mirror to move up and down.

With auto-focusing function, the machine can automatically adjust the focus to the most suitable position when machining different materials and different thicknesses. This can significantly improve the processing efficiency of laser cutting machine, heavy plate perforation time will reduce.

The above is the advantage of auto-focusing laser head all the content, I hope this article can help you.
