  •   All Spindles are test run to maximum rpm
  •   Spindles are initially ran at 5% of maximum speed
  •   Bearing Temp & vibration are checked.  Once verified to be with  
           OEM specs, the rpm is increased to 10% of max. rpm
  •   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
Run-in Procedure
Testing Equipment and Capabilites
  •  Grease packed spindles
  •  Belt-Driven Spindles
  •  Motorized Spindles
  •  Oil Mist Lubricated Spindles
  •  High Frequency Spindles (Up to 250,000 rpm)
  •  Cartridge Spindles (Special Fixtures are built)
  •  Pressure Checks to detect leaks
  •  All drawbars checked with Pull Force Rention Guages
Spindle Repair Testing
All spindle repairs go through 6 to 8 or rigorous testing.  Our testing
procedures including complete break in of the spindle as well as
testing of the drawbar, encoders, sensors, motor, taper, and
vibration analysis is performed through the entire test of all spindles.
