2 EVALUATION Company P.O.C. Phone # Job # Model Serial # -Remarks & Probable Cause of Failure: -Nose Taper Ball Measurement.059 -Encoder Make & Model # FANUC -Spindle RPM 12,000 -Sensor Make & Model N/A -C W/O Tool Dimension: Face of Shaft to Fingers N/A 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. Person Evaluating Spindle: Date: 2

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 RMR Spindle Repair, ***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. Assembled By: Tested By: Assembly Date: Test Date:
