Darex XPS-16 Operating Instructions - Manual (Page 39)

WHY:
Your drill is
aligned with the aid of a
fiber optic sensor. The
fiber optic sensor locates
and positions the cutting
edge
at 12 o’clock.
(vertical)
This alignment process was designed
for drills with a straight cutting edge.
Drills with a hook in the cutting edge
can still be sharpened, but the cutting
edge may not align correctly. If this is
the case, it may be necessary to
manually correct the alignment posi-
tion, using the Advance feature of the XPS-16.
As the drill moves towards and in front of the sen-
sor, the sensor moves and positions itself at 55%
of the drill diameter. The drill starts to rotate,
once the cutting edge breaks the beam of light, it
records that point and the sensor then moves to
80% of the drill diameter.
The cutting edge continues to
rotate, breaking the beam of
light for a second time. The
machine recognizes the two
detected points as the cutting
edge,
THEN,
rotates those points
in to the
12 o’clock position. (vertical)
Most times, if the drills cutting
edge is straight, the alignment will be correct, and
a two-point alignment will successfully position
the cutting edge.
BUT:
When the cutting edge of the drill is
hooked, the second alignment pick
point may be in the radius of the hook.
The true cutting edge
will not be positioned
correctly at 12
o’clock. (vertical)
When you see the
alignment is incorrect,
touch Cycle Stop and
bring the machine
back to the home position. You must then com-
pensate for the incorrect alignment using the cut-
ting edge Advance Screen.
When using the
Advance screen,
the cutting edge
will be detected
using only a single
point detection
process. The drills
cutting edge will
rotate into the
beam of light as
before, but will
only pick one
point,
then the cutting
edge will rotate
as close to 12
o’clock (vertical) as possible.
At this point, if the cutting edge does not rotate
up to 12 o’clock (vertical), you will need to com-
pensate manually.
