BT240S 3KW 2D Laser Cutting Head User Manual
Increase the function of replacing of dust-proof of focus protective lens;
Nozzles, focus lens and collimating mirrors all have a cooling structure;
Increase the active anti-collision function (this function can be realized only with the
corresponding sensor);
Carry out gas path optimization to make the auxiliary cutting gas more concentrated and
improve the cutting efficiency and cutting quality;
Improve the structure of QBH connecting base, which enhances reliability;
Increase the indication and correction function of "zero focus" scale;
Tight sealing design greatly reduces the contamination probability of lens.
As shown in Figure. 2, the laser head includes four basic units, namely 1) collimation module
component CM, 2) focusing module component FM, 3) protection window module component WM,
and 4) nozzle module component TM to make up a light beam.
1
）
CM component: finish the fiber collimation function, collimate the incident laser beam into
parallel beams and make center-regulation;
2
）
ATP component: adjust the angle of the incident beam for the laser head of collimated light
that does not require collimation, that is, the center-regulating of beam;
3
）
FM component: focus collimating beam to a high power density convergent beam, and make
the focus position to move up and down;
4
）
WM component: protective lens can protect the focusing lens from the damage of return slags
and extend the life of focusing lens;
5
）
TM component: guide the convergent beam to the workpiece and generate high-speed airflow
jet joint-cuttings to achieve high-quality cutting.
