Spindle Repair Testing
All Spindles are test run to maximum rpm.
Spindles are initially ran at 5% of maximum speed.
Bearing Temperture & vibration signaltures are checked.  
Once verified to be with OEM specs, the rpm is increased to 10% of max. rpm.
Bearing Temperture & vibration signaltures are again re-checked and they pass the spindle
rpm is increased in intervals of 10% maximum rpm until the unit is ran at max rpm for 8 hrs.

All spindle units are checked before & during the increase of rpm at all intervals
Once they are proven to be within OEM specs they are increased by 10% intervals of the
max rpm until max rpm is acheived

When max rpm is achieved the spindle is ran for 1-2 hours
Only when bearing temp & the vibration analysis readings are within spec is the unit
approved for shipment
