People in the industry know that the laser cutting head is one of the important accessories for the laser cutting machine. The traditional cutting head only has a focusing lens and a nozzle, and has no auto focusing function. In the large format laser cutting machine, the processing height at different places is slightly different, which causes the surface of the material to deviate from the focus. In this way, the size of the focus spot at different places is different, and the power density is also different. The laser cutting quality at different cutting positions is very different, which cannot meet the quality requirements of laser cutting.

The main features of the laser cutting head include:

1) YAG laser cutting system applicable to 1064nm wavelength.

2) It is applicable to laser cutting systems with laser power below 1000W.

3) The nozzle gap servo system can keep the gap between the nozzle and the cutting steel plate at 1-20mm, the response time is less than 5ms, and the control accuracy is 0.2mm.

4) Independent and perfect Z-axis function, with adjustable focus position. It also has automatic/manual working mode, rising/falling inching control, automatic tracking/automatic reset function, multiple gap setting modes, and servo driver zero drift suppression function.

5) The perfect NC interface can be easily connected with most controllers. The machine controller or cutting program controls the opening, closing and zeroing of the automatic tracking function of the cutting head.

The above is the characteristics of the laser cutting head. Don't underestimate such a small part. Without its cooperation, the laser cutting machine will not be able to cut.
