BM114S SERIES 6KW Laser Cutting Head User Manual
Entry J axis detection, “closed loop and initiate enable”. Move J axis to see whether the action
is normal. Scale 0+ indicates J+. Check encoder and speed.

Interface Operation
1.
Move J axis to check if the action is normal (“thread pitch” and direction), J+ indicates
scale 0+.
2.
Slowly moving the J axis so that it meets the positive and negative limit, check whether
the direction and limit signal are normal or not.
3.
By click homing icon, J axis moves to negative direction and do 2
nd
homing when touches
negative limit. In this case the position of zero point coincides with zero focal position.
The homing is finished.
Note:
1.
Click+, the lens holder moves upward. When it touches positive limit, click -, then lens
holder moves downward to the negative limit.
2.
The direction of origin is negative, and take lower limit as a sampling signal.
3.
Pitch 2mm, 10000 pulses per turn.
4.
Positioning speed is recommended 50-100mm/s.

Beam Adjustments and Focusing

Beam Adjustments (QBH interface)
Cutting quality in a great extent depend on whether the lens is in the middle. If the lens is
not in the middle, the laser beam may contact with nozzle or inner wall to produce high
temperature deformation. Lens centering operation should be considered when nozzle is
replaced or the cutting quality is decreased.
Lens centering of laser cutting head can be finished by adjusting Collimating mirror, X-Y
direction. The adjusting screw is located on the top of the cutting head as shown in Figure 5.1.
