• AnalysisOur technicians thoroughly inspect the spindle to identify the problem correctly before moving ahead with any spindle repair work. All spindles are subjected to the following 5 point assessment:
  • Incoming Vibration Aanalysis Incoming vibration analysis is performed in order to determine: bearing condition, level
    of unbalance, non-repetitive runout.
  • Assembled Spindle Inspection Pilot ID or taper runout on tool end of shaft to determine possible spindle crash or
    improper tooling.
    Rear taper runout inspection to determine possible over tightening of belts or improper
    tooling.
    Preload test to determine bearing wear or spindle crash.
  • Disassembled Spindle Inspection Pilot ID or taper inspection to determine spindle crash, improper tooling or overheating.
    Bearing journal inspection to determine improper bearing fits or use of spindle after
    initial failure.
    Overall shaft condition to determine crash, overheating, lack of coolant or overloading.
  • Bearing Condition An inspection of bearings is performed under lab conditions by factory trained bearing
    specialists to determine lack of lubrication, over speeding, spindle crash, overloading,
    loss of preload, contamination (coolant or other material) or overheating due to
    electrical problems.
    In addition, we have the access to all Bearing OEM’s facilitation and personnel.
  • Engineering Recommendations We recommend spindle design changes or enhancements to improve spindle longevity
    and/or performance. For example, if a spindle has failed due to contamination, a design
    change such as new labyrinth nuts, air purging, hybrid bearings or improved sealing
    design will be recommended and implemented.
