The spindle rotates by hand, but with a loud growl coming from the bearings. The exterior is covered with metal
shavings and debris. There are several spots of corrosion throughout the interior of the spindle. This may be an
indication that the spindle chiller temperatures are too cold, forming internal condensation, which can lead to random
spots of corrosion. The nose air purge port and labyrinth is packed with coolant and sludge. There should be a clean
and dry source of air for the spindle air purge system. Cutting coolant should also be directed away from the nose of
the spindle. The nose bearings are very contaminated. Contamination is the main probable cause of failure. The draw
bar is caked with black grease. The draw bar stem shows heavy wear. Grind, plate and finish grind the draw bar stem.
The nose plunger spring is broken. Replace nose plunger spring. Overhaul draw bar and document pullforce. There
are numerous imperfections in the tool nose taper. Grind, plate and finish grind the tool nose taper. The tail bore has
heavy wear. Grind, plate and finish grind the tail bore.

Comments/Recommendations:
***Customer to run in spindle after installation into machine. Start @ 1,000 RPM and let run until temperature shows no
increase or a minimum of 30 minutes. Increase in 1,000 RPM increments until reaching maximum RPM. Do not let
temperature rise above 130° F during run in process. If temperature reaches 130° F, shut spindle down and let cool to
below 100° F and proceed with process. Do not run spindle above 80% of maximum RPM for the first 40 hours of
operation. Questions, call Randy @ RMR Spindle Repair, 262-285-3252.
***If spindle is shut down for greater than 8 hours, a spindle warm up procedure is crucial to the longevity of the spindle
life. Warm spindle up at 25% of maximum RPM for 15 minutes before manufacturing process has started. Failure to
perform this warm up cycle could cause premature bearing failure, thus voiding the spindle warranty.
