Abstract:
Deep drilling device for drilling holes in workpieces in which the holes can be drilled at different positions and in different orientations relative to a work longitudinal axis, comprising:a deep drilling unit with at least one headstock, which has at least one main spindle rotatable by a spindle drive about a horizontal spindle axis for the reception of a deep drilling tool, the deep drilling tool being displaceable parallel to the spindle axis;a work holding unit with first rotation means for holding at least one workpiece with horizontally oriented work longitudinal axis and for rotating the workpiece about a vertical rotation axis;a first positioning device for relative displacement of workpiece and deep drilling tool parallel to a horizontal, first axis (X axis) at right angles to the spindle axis;a second positioning device for relative displacement of the workpiece and the deep drilling tool parallel to a vertical, second axis (Y axis) perpendicular to the spindle axis;and a third positioning device for relative displacement of the workpiece and the deep drilling tool parallel to a third axis (W axis) parallel or at an acute angle to the spindle axis; andthe second rotation means being adapted for rotating the workpiece about the vertical rotation axis into and out of a loading or unloading position for horizontally loading or unloading the workpiece into or out of the work holding unit.
