摘要

The lathe with a movable driven Z-slide in a Z-axis has at least one first spindle unit rotatably driven and located in the Z-slide. The Z-stroke of the Z-slide activates the axial forward feed for the lathe work of a workpiece clamped on the first spindle unit. At least one second spindle unit is rotatably located on the Z-slide for clamping a further workpiece. The second spindle unit (4) has a hollow shaft rotatably driven located on the Z-slide, in which an unrotatable and axially displaceable work spindle is located. A servo motor (15) as a position drive drives a ball roller spindle (16), which is located in a housing flange (23) of the spindle housing (5). A forward feed flange (25) transmits the axial movement of the ball roller spindle to the work spindle.
