What are the advantages of the auto zoom laser head?

As we all know, laser cutting machine has unparalleled advantages in the metal processing industry, not only the cutting precision is high, but also the section is smooth and burr-free, whether it is cutting thick plate or thin plate can achieve the effect desired by customers, and the cutting effect Good or bad has a lot to do with the focus control of the laser cutting machine. In order to achieve better cutting effect when cutting thick plates, the focus of the laser beam will be set in different places.

In laser cutting applications, the main way of focusing is to rely on manual to complete. Nowadays, with the development of laser technology, this manual focusing method has been gradually eliminated, and the auto-focusing function has begun to be realized slowly. The laser cutting machine of the holmium laser can be equipped with a fully automatic focusing function. Then, some people will say that the light path is integrated in the cutting head. Can the focus function be achieved by changing the height of the cutting head? The cutting head is raised, the focus position is high, the cutting head is lowered, and the focus position is low. However, it turns out that it is not as simple as everyone thinks.

How to focus the laser cutting machine?

The bottom of the laser cutting head is a nozzle. During the cutting process, the distance between the nozzle and the workpiece (nozzle height) is about 0.5 to 1.5 mm. It may be regarded as a fixed value, that is, the nozzle height is constant, so it cannot be lifted by the cutting head. Focusing (otherwise the cutting process cannot be completed).

The focal length of the focusing mirror is immutable, so it cannot be expected to focus by changing the focal length. If the position of the focusing mirror is changed, the focus position can be changed: when the focusing mirror is lowered, the focus is lowered, and the focusing mirror is raised, and the focus is raised. - This is indeed a way of focusing. Automatic focusing can be achieved by using a motor-driven focusing mirror for up and down motion.

Another method of auto-focusing is to set a variable curvature mirror (or adjustable mirror) before the beam enters the focusing mirror, and change the divergence angle of the reflected beam by changing the curvature of the mirror to change the focus position.

With the auto focus function, the machine can automatically adjust the focus to the most suitable position when machining workpieces of different materials and thicknesses. This can significantly improve the processing efficiency of the laser cutting machine, and the slab perforation time will be greatly reduced. Therefore, for the laser cutting machine, the auto focus function is an important and indispensable function.

What are the benefits of auto focus?

Auto-Zoom Before the beam enters the focusing mirror, a variable curvature mirror (or adjustable mirror) is placed. By changing the curvature of the mirror, the divergence angle of the reflected beam is changed to change the focus position.

This can significantly improve the processing efficiency of the laser cutting machine, and the slab perforation time will be greatly reduced.
