BM109 SERIES 1.5KW Auto-Focusing Laser Cutting Heads
Maximum acceleration of focus lens driver 10m / s2, maximum speed 6m / min;
The drawer type lens holder makes the replacement of protective lens more quickly and
easier
The composite lenses were used for collimation and focusing to obtain the best optical
quality and cutting effect;
With QBH interface, can be adapted with various fiber lasers.
1.2 Structure & Function
As shown in Figure 1, the laser head consists of five basic units, such as collimated water-cooled
module, collimation centering module, focus drive module, protective lens module, nozzle module.
Collimated water-cooled module: complete the function of cooled collimating module, water-
cool the collimation centering module;
collimation centering module: complete the function of fiber collimation, collimate incident laser
into parallel beams with centering function;
Focus drive module: focus the collimated beam to a high power density convergent beam and
realize automatic adjustment of the focus position by the driving device;
Protective lens module: protecting lens can protect focusing lens from the damage of return slags
and extend the life of focusing lens;
Nozzle module: guide beams to the processing workpiece and produce high-speed air jet joint-
cutting to achieve high-quality cutting.
