In the beginning,Laser cutting machine manufacturersoflaser pipe cutting machineThe application of focusing mainly depends on manual. With the continuous development of laser technology, manual focus will eventually be eliminated and replaced by an autofocus function. A high power laser tube cutting machine effectively has an auto focus function. However, some people will say that the optical path is integrated in the cutting head, we can not simply change the cutting head its height? When the cutting head is up, focus on the high, when the cutting head is down, focus on the low position. However, it turns out that this is not so simple.

Laser cutting machine manufacturersoflaser pipe cutting machineThere is a nozzle at the bottom of the cutting head. In the cutting process, the distance between the nozzle and the workpiece(Nozzle height) is about 0.5-1.5mm, which can be regarded as a fixed value, that is, the nozzle height does not change, so it is impossible to achieve focusing by lifting the laser head.

The focal length of the focusing lens is constant, so it is not practical to change the focal length of the focus. Changing the position of the focusing mirror will correspondingly change the main position of the social focus: if the focusing mirror drops, the focus will drop; The focus mirror rises and the focus will rise. This is indeed such a focusing work method, using a student control motor technology to drive the focusing mirror to move up and down, which can realize automatic focusing by information.

Laser cutting machine manufacturersoflaser pipe cutting machineAnother method for automatic focusing is: the front beam enters the focusing lens is placed on a variable curvature mirror (or adjustable mirror), and the divergence angle of the reflected beam is changed, and the focal position is changed by changing the curvature of the mirror. With the system automatic focusing function, when processing enterprises with different learning materials and different thicknesses of workpieces, the machine equipment can automatically and quickly adjust the focus to the appropriate position through numerical control at the same time. Therefore, a significant level of improvement can be obtainedlaser pipe cutting machineThe processing production efficiency can also be developed to greatly reduce the perforation time of thick plates.

Therefore, the autofocus function isLaser cutting machine manufacturersoflaser pipe cutting machineAn essential function.
