Darex XPS-16 Operating Instructions - Manual (Page 61)

61
1. Use MIN MTO when touching up your facet
and conic ground drills.
2. Use MID MTO when sharpening chipped facet
and conic ground drills.
3. Use MAX when changing point angles on conic
ground drills only.
4. If your drill has a broken or highly misshaped
geometry, you will want to rough grind on the
XT3000 first.
5. If your drill has one cutting edge grossly
longer that the other, when you insert the drill
into the chuck, position the longest side down.
The sensor will detect the most protruding
edge and adjust its grind accordingly.
6. If you enter a drill diameter size outside the
capability range of the sharpener, the setting
will default to the closest MIN/MAX diameter
size.
7. To make wheel changes faster, using a per-
manent marker, write the X & Z wheel offset
values on the back of the wheel. After each
wheel change, type in the offset from the back
of that wheel.
8. To extend the life of and improve the perform-
ance of your wheel, clean each new wheel be-
fore using. For wheel cleaning instructions Re-
fer to information on page 57.
9. To adjust the parallelism of the facets, rotate
the cutting edge using the Advance button.
For more information Refer to page 39.
10. Each time the XPS-16 is powered up, it de-
faults to the Darex File and reloads all default
offset values.
11. Make sure each time you power down the
XPS-16, you save your work, just as you
would on a PC. To save or create a file, Refer
to information on pages 23 & 24
12. If the XPS is having trouble picking up the
drills cutting edge, paint just behind the cut-
ting lip, using white correction fluid such as Bic
Wite-out. Because the fiber optic sensor works
from reflectivity, the color of the drill may in-
terfere with the alignment. Drills Black and
Gold in color, are the biggest culprits. Painting
just behind the cutting edge will help the sen-
sor locate the cutting edge.
13. For a thick webbed drill, mark inside the flute
using a black marker. Paint just under, and
right up to, but not touching the cutting edge.
14. To increase the hone on the cutting edge of
the drill, increase the length of time the drill is
in the honing cycle.
15. If your drill has a thin web, we do not recom-
mend sharpening it as a facet point style. The
width of the primary facet produced will be
very thin.
16. Be careful when chucking up carbide drills.
Center the drill in the jaws as you tighten the
chuck. It is helpful to rotate the drill as you
tighten down the chuck. Be careful not to over
tighten the chuck on small drills.
17. You can influence the size of the radius cre-
ated on an R-Split drill. Measure web of drill.
Enter a web thickness value smaller than the
drills actual web diameter. Watch the C Axis
rotation, it will automatically advance the drill
in the + direction and could nick the opposite
cutting edge. Adjust the C Axis rotation in the
minus direction. For more details see page 35.
