Two adjusting screws
(1
,
2)
are used to centre the beam position.
Adjustment range:
±1.5 mm
Tool:
Allen key (size 2 mm)
If the machine manufacturer does not prescribe a different procedure, we
suggest that you follow the steps described below:
1. Screw in a nozzle with a large nozzle opening.
The nozzle opening should be considerably larger than the laser beam diameter at the
nozzle opening.
If the nozzle is too small for the nozzle opening, the nozzle can be removed.
2. Glue the sample under the nozzle.
Caution laser beam
(laser class 4)
– Wear laser goggles!
• Avoid radiation to eyes or skin caused by direct or scattered radiation.
• Use laser goggles
(in compliance with DIN EN 207)
that are designed for the
wavelength of the connected laser.
3. Trigger a low-power laser pulse and judge the penetration in the sample.
The penetration must be round and in the centre of the nozzle opening. If not, the lens
must be centred.
4. Centre/align the beam position using the adjusting screws (1, 2) on the laser head.
Attention:
The maximum adjustment range is ±1.5 mm.
5. Use a new sample. Trigger a low-power laser pulse and judge the penetration in
the sample again.
The penetration must be round and in the centre of the nozzle opening.
Repeat the procedure from
step 2
until the laser beam is in the middle of the nozzle
opening.
When the laser beam is in the middle of the nozzle opening, a nozzle with a
smaller opening should be screwed into the sensor insert. Then repeat
step 2
until the laser beam is in the middle of the nozzle opening again.
When the laser beam has been adjusted, the laser beam must be in the centre
of the nozzle (nozzle with the correct opening diameter for the cutting process).
To avoid any damage, do not obstruct the laser beam.
