Fiber laser cutting head description

Swiss RAYTOOLS is an automatic focusing fiber cutting head. The product has an external servo motor and a built-in drive unit, which drives the focusing lens to automatically change its position within a range of about 22mm through a linear mechanism. The user can set the continuous focus through the program to complete the rapid perforation of thick plates and automatic cutting of different thicknesses and materials. sheet. The product can be equipped with a compound lens group to integrate the beam, and the diversified interface positions enable it to be used with various fiber lasers; the optimized optics and water-cooling design enable the laser head to work continuously and stably for a long time at high power.


Features of laser cutting head

● Optimized optical configuration and smooth and efficient airflow design.

● The automatic focusing range is +10~-12mm, and the adjustment accuracy is 0.05mm.

●  All lines and air pipes are routed from inside to avoid unnecessary collision and damage.

● The maximum acceleration of the focusing lens drive is 10m/s², and the maximum speed is 10m/min.

● The drawer-type lens holder is used to make lens protection quicker and easier.

● Both collimation and focusing use compound lenses to obtain the best optical quality and cutting effect.

● With QBH, QD, QCS, PAPI, LLK-D and other fiber interfaces, it can be adapted to various fiber lasers.


The structure and function of the laser cutting head

The laser head consists of four basic units: collimation module, focus drive module, protective mirror module and nozzle.

1. Collimation module: completes the fiber collimation function, collimates the incident laser into a parallel beam and has the function of centering.

2. Focus drive module: focus the collimated beam into a converging beam with high power density, and realize the automatic adjustment of the focus position through the drive device.

3. Protective lens module: The protective lens can protect the focusing lens from the damage of returning slag and prolong the service life of the focusing lens.

4. Nozzle module: guide the focused beam to the workpiece, and generate high-speed airflow to jet the slit to complete high-quality cutting.
