Zusammenfassung:The machine tool (10), for machining a rod-shaped workpiece (20), has a tool spindle (26) and an initial workpiece holder (14). A second workpiece holder (54,56,58) is coaxial to the first, in the working position., to give a rotating or swing movement of at least 180 deg. around an axis (46) at right angles to the longitudinal axis (17) of the workpiece. The second workpiece holder has a different structure as a steadyrest (56), center sleeve (54) or a force clamp pedestal (58).
