Spindle Break-In

You must complete this procedure to main-
tain the warranty. Failure to do this could
cause rapid wear-and-tear of spindle bear-
ings once they are placed under load.
The spindle break-in procedure distributes lubri-
cation throughout the bearings to reduce the risk
of early bearing failure if there are any "dry" spots
or areas where lubrication has settled in the bear-
ings. You must complete this procedure before
placing operational loads on the spindle for the
first time when the machine is new or if it has
been sitting idle for longer than 6 months.
Always start the spindle break-in at the lowest
speed to minimize wear if there are dry spots.
Allow the spindle to run long enough to warm up
and distribute the bearing grease, then incremen-
tally increase spindle speeds and repeat this pro-
cess at each speed until reaching the maximum
spindle speed. Following the break-in procedure
in this progressive manner helps minimize any
potential wear that could occur before lubrication
is fully distributed.
To perform spindle break-in procedure:
1. Successfully perform all steps in Test Run
section beginning on Page 23.
2.
Configure V-belts for a spindle speed of
230 RPM (refer to Spindle Speed, beginning
on Page 30 for detailed instructions).
3. Connect machine to power, turn it ON and let
it run for 10 minutes in each direction.
4. Turn machine OFF, allow spindle to come
to a complete stop, then DISCONNECT
MACHINE FROM POWER!
5. Repeat Steps 2–4 for 1200 RPM, and then
for 2520 RPM.
Congratulations, the spindle break-in is now
complete!

Inspections &
Adjustments
The following list of adjustments were performed
at the factory before the machine was shipped:
• Gib Adjustments ..............................Page 47
• Leadscrew Backlash
Adjustments .................................... Page 48
Be aware that machine components can shift
during the shipping process. Pay careful atten-
tion to these adjustments during operation of the
machine. If you find that the adjustments are not
set according to the procedures in this manual or
your personal preferences, re-adjust them.
Since the mill head has been moved around
for shipping purposes, you will need to tram
the spindle with the table to ensure a 90°
alignment. Refer to the Tramming Spindle
section on Page 50 for detailed instructions.
