Metal cutting tool: auto focus cutting head NC30

In the early days of laser cutting applications, the main way of focusing is to rely on manual focus. Now with the development of laser technology, this manual focusing method has been gradually eliminated, and the automatic focusing function has gradually been realized. There are prophets Insight Laser's full range of laser cutting machines are equipped with fully automatic focusing functions. The optical path is integrated in the cutting head. Can the focusing function be achieved by changing the height of the cutting head?

When the cutting head is raised, the focus position is high, and when the cutting head is lowered, the focus position is low. However, it turns out that it is not as simple as everyone thought. The bottom of the laser cutting head is the nozzle. During the cutting process, the distance between the nozzle and the workpiece (the height of the nozzle) is about 0.5 to 1.5 mm, which can be regarded as a fixed value, that is, the height of the nozzle remains unchanged, so it cannot be adjusted by raising and lowering the cutting head. Focus (otherwise the cutting process cannot be completed). The focal length of the focusing mirror is immutable, so you can't expect to adjust the focus by changing the focal length.

If you change the position of the focusing mirror, you can change the focus position: when the focusing mirror goes down, the focus goes down, and when the focusing mirror goes up, the focus goes up. - This is indeed a way of focusing. Using a motor to drive the focusing mirror to move up and down can realize automatic focusing.

Another method of automatic focusing is: before the beam enters the focusing lens, a variable-focus collimating lens group (or adjustable mirror) is installed, and by changing the focal length of the collimating lens, the divergence angle of the reflected beam is changed, thereby changing the focus position. With the automatic focusing function, the machine can automatically adjust the focus to the most suitable position when processing workpieces of different materials and thicknesses. In this way, the processing efficiency of the laser cutting machine can be significantly improved, and the perforation time of the thick plate can be greatly reduced.

Therefore, for the laser cutting machine, the automatic focusing function is an important and indispensable function.
