Abstract
A spindlehead arrangement having a headstock and a driving spindle motor mounted separately of each other for vertical movement on separate tracks. The headstock is capable of being removed from its set of supporting tracks without necessitating a removal of the spindle driving motor. A releasable connection is provided between the headstock and the spindle driving motor to facilitate a movement of the headstock and the spindle driving motor in unison along the track. A counterbalance weight is provided for counterbalancing the weight of the headstock and the weight of the spindle driving motor.
