HR Operation Manual

2.4.2 Manual

The beam must be centered in the tip.



Move the tip to the center of Z-
axis travel for the best possible
results.



Check the beam alignment during
initial installation or whenever the
fiber, collimator optics or focus
optics are replaced.

Do not look directly into the red
beam.

Visually locating the beam inside
the tip orifice can be difficult.
Adequate lighting and a

magnifying glass are highly
recommended.

If necessary, Laser Mechanisms
offers an alternative solution. See

Section 2.4.1, Beam Centering

Camera

To manually center the beam in the
gas jet tip (see

Figure 13

1. Verify that the high power beam is

disabled.

2. Put a piece of translucent tape on

the end of the gas jet tip.

3. Turn on the red aiming beam from

the fiber laser and observe the
position of the beam on the tape.
If the beam is not centered in the
gas jet tip orifice, proceed to step
4.

4. Adjust the opposing XY

adjustment screws (see

Figure

) so the beam is centered in the

nozzle orifice.



Loosen the adjustment screw
in the desired direction then
tighten the opposing screw
(180° away, on the opposite
side of the head).



One set of screws adjusts the
X direction. The other set of
screws adjusts the Y
direction.



Some trial and error may be

necessary.



The image on the screen
should be similar to

Figure

Verify all screws are tight
after adjustment is
complete.
