DRILL STICK OUT- FINAL GRIND:
IMPORTANT: This step is NOT necessary
for the XT-3000-A & XT-3000I-A Com-
plete.
The Drill Stick Out - Final Grind amount on the
Auto Sharpening system must be calibrated to
produce the same Drill Stick Out - Final Grind
amount as produced on your existing Manual
Auto Sharpening Fixture
Before you begin sharpening with your Auto
system, take the time to calibrate Final Grind-
Drill Stick Out. This will help retain your cur-
rent point split depth calibration.
Verify Final Grind Drill Stick Out On Manual
System First:
1. Rotate material removal knob
to minimum take off setting.
2. Align drill in chuck. Once drill is
set to length, aligned and
securely captured in the chuck, remove from
alignment port.
3. Using a height gauge,
measure the amount of
drill protruding from the
end of the chuck to the
tip of the drill. (Drill
Stick Out - Before Grind)
4. Sharpen the drill
until spark out has
been achieved.
Remove chuck from
sharpening port. With-
out removing
the drill, re-measure the
amount of Drill Stick Out
after grinding. Your
Auto system must be adjusted to produce the
same Final Grind - Drill Stick Out measure-
ment as the manual system.
5. Remove the Manual System and install the
Auto Sharpening System.
6. Using the same drill bit, repeat steps 1-4 to
determine the Final Grind - Drill Stick Out
measurement currently produce by the Auto
Sharpening System.
You will need to adjust the Swing Bearing
assembly on your Auto sharpening attach-
ment to duplicate the Final Grind - Drill Stick
Out measurement produced by the Manual
system, see page 21 for calibration details.
