Abstract
A high speed spindle preferably of the motorized type is described having means for axially preloading the spindle bearings and hydraulic preload locking means for locking the preload against diminution by expected axial pull-out forces exerted on the spindle shaft counter to the preload during machining. The hydraulic locking action is released in the event unexpectedly high, potentially damaging axial pull-out forces are encountered during machining.
