Abstract: A machine tool for the machining of elongate workpieces includes a workpiece support column having workpiece support components for supporting a first workpiece and second workpiece support components for supporting a second workpiece. The first workpiece support component and the second workpiece support component are arranged for supporting the first workpiece vertically above the second workpiece. The workpiece support column is rotatable around a vertical axis so as to shift the workpieces between the machining station and a station for loading and unloading of workpieces. The workpiece support component include a drive element for applying torque to the workpieces for machining of the workpieces by turning. A motor and chuck assembly and a method of machining workpieces are related.

Abstract: A machine for machining workpieces, including a first column and a second column facing each other according to a first horizontal axis, a guide system guided displacement of at least one of the columns in parallel with the first horizontal axis, one or two tool units, each tool unit being arranged on respective column for controlled displacement perpendicularly to the first horizontal axis, on each column, a workpiece holding device, at least one of the workpiece holding devices being arranged for controlled displacement in parallel with the first horizontal axis, where the workpiece holding devices are arranged for supporting a workpiece between them and for controlled rotation of the workpiece around a workpiece axis parallel with the first horizontal axis.
