  • DRILL SPINDLE UNIT
    Publication number: 20110255930
    Abstract: A drill spindle unit includes a housing, and a rotatable and longitudinally displaceable drill spindle provided with axial keyways for cooperation with internal projections of a drill spindle surrounding rotation drive sleeve, and a screw thread for cooperation with an internal thread of a drill spindle surrounding feed drive sleeve. Bearings for radial as well as axial support of the drill spindle relative to the housing are provided.
