The Components of the Fiber Laser Cutting Machine II-laser cutting head
The component of fiber laser cutting machine-laser cutting head.
First, the laser cutting technology adopts a cutting head to focus the laser light.
And the laser into a high-power density laser to cut the material.
Second, the laser cutting head is a laser output core device.
Then it includes a focusing mirror, a focusing lens, a nozzle, a sensor, and a control system.
Among them, one of the key factors affecting the cutting efficiency is the shape of the nozzle in the cutting head.
Then the characteristics of the flow field generated.
Reasonable auxiliary gas types and flow fields not only improve the processing capacity, but also limit the heat affected zone to a small range to ensure the processing quality.
In the laser cutting process, the distance between the cutting head and the material is an extremely important factor.
It directly affects the cutting quality.
During the cutting process, to avoid collision between the cutting head and the protrusion of the material, it would cause damage to the nozzle, cutting head or material.
And the laser cutting head must install a special sensor to automatically.
And it detect the change of the distance and automatically adjust accordingly.
Therefore, the distance between the cutting head and the material keeps constant, thus ensuring stable cutting quality and increasing process safety.
For different materials, adjusting the laser cutting head is necessary.
A good laser cutting head can effectively improve the cutting effect and cutting speed. Inferior cutting heads can’t even be cut on certain materials.
Therefore, we have to choose the right laser head.
Then we adjust the laser cutting head height according to different materials to meet the laser processing needs.
