2.5.1 QCS Beam Center-regulating
If the angles of the red dot on the optical fiber and the red dot on the laser head interface are too
far away from each other when the optical fiber connector is inserted into the interface, resulting in
failure of aligned insertion, at this time, refer to the following steps to adjust the position of the fiber
interface on the laser head to solve this problem, as shown in Figure 4-1.
Unscrew 4 locking nuts in the position of the part with a wrench. Be careful not to turn the screw
down,
rotate the QBH interface, and tighten the screw when in place.
The optical fiber insertion method of BT240S QCS interface is shown in Figure 4-2.
(1) Loosely locking rings 1 and 2.
(2) Horizontally insert the fiber interface
(3) Lock the locking rings 1 and 2 and use the wrench if necessary.
2.5.2 QBH Beam Center-regulating
The best cutting quality depends largely on the central lens. If the lens is not in the middle, the
laser beam may contact with the nozzle or the inner wall, which will cause high temperature
deformation.
When the nozzle is replaced or the cutting quality is reduced, it is necessary to conduct the center-
regulation of the lens.
The center-regulation of BT240S products can be done by adjusting the position of the collimator
mirror in the X-Y direction. The adjusting screw is located on the cutting head, as shown in Figure 5-
