How to resolve
The attached tool does not run true
1. Inside the drill press spindle
2. Morse Tapered tool/ arbour
3. Chuck
4. Attached tool
Note:
The NOVA specification of the axial
runout is:
±
0.02mm on Spindle Morse Taper
±0.04mm on end of arbour
±0.18mm on end of 100mm straight
rod attached to a chuck.
The solution will differ based on
where the run out is detected at:
1. Inside the drill press spindle
-
The entire spindle assembly
should be replaced
2. Morse Tapered tool/ arbour
-
Make sure all the contacting
surfaces are cleaned
-
If the tool still has runout after
all surfaces has been
cleaned, try changing the tool
to another one.
3. Chuck
-
Replace the chuck to another
4. Attached tool
-
Make sure the tool is
mounted on the chuck
correctly.
Note:
When checking the cause of the
runout, always make sure to check
from the spindle.
Quill does not retract back
1. Return spring
2. Quill and quill housing
-
Make sure all surfaces are
lubricated sufficiently without
excess contaminants.
3. Handle pinion gear
-
Make sure all contacting
surfaces are covered with
sufficient amount of
lubricants.
Note:
Support the quill to make sure it does
not fall out from the headstock.
1. Carefully release the locking bolt
from the return spring housing
and hand tighten by rotating it in
the anti-clockwise direction. Lock
the spring housing by using the
locking bolt before releasing.
2. Extend the quill as far as possible
and apply lubricant of relatively
high viscosity. Move the quill up
and down a couple of times to
spread the lubricant.
3. Remove the handle spring and
release the locking set screws to
extract the handle from the
headstock. Apply lubricants on all
contacting surfaces and then
reassemble everything back
together.
