Abstract: In order to improve a lathe includes a machine frame, a workpiece spindle unit arranged on the machine frame and having a workpiece spindle housing and a workpiece spindle rotatingly drivable about a workpiece spindle axis in the workpiece spindle housing. A supporting unit which is arranged on the machine frame and in which a workpiece receptacle rotatable about the workpiece spindle axis can be supported on the machine frame radially to the workpiece spindle axis, in such a manner that rotary machining operations other than longitudinal turning are possible in a simple manner. It is suggested that the supporting unit have a bearing member receptacle, in which a guide bushing for longitudinal turning can be supported in the area of its workpiece receptacle in a longitudinal turning version of the lathe and the workpiece spindle unit can be supported in the area of its workpiece receptacle radially to the workpiece spindle axis in a short turning version of the lathe.

Abstract: In order to improve a machine tool comprising a first spindle for accommodating a workpiece and a first carrier for machining units movable along an X axis, which can be moved relative to one another along a Z axis, a second carrier which is movable along an X axis and with which machining units can be moved into or out of a functional position associated with the first spindle in a transverse direction extending transversely to the X axis and transversely to the Z axis, as well as an additional carrier for machining units in such a manner that it offers optimum possibilities for the machining of a front side of a workpiece and a rear side of a workpiece, it is suggested that the second carrier bear a second spindle, that as a result of movement of the second carrier the second spindle be movable in the direction of the Z axis and the transverse direction between a workpiece takeover position and at least one workpiece machining position and that the additional machining units be arranged in a spatial area, i

Abstract: In order to improve a receiving unit for tools or workpieces, comprising a receiving member (14) and a clamping apparatus (30) for the tool or workpiece which is associated with it and has clamping elements (40) of a clamping device (32) arranged in a receiving area (26) of the receiving member (14) and a unit (60) for generating a clamping force, in such a manner that a more simple actuation of the clamping device (32) is possible whilst maintaining a reliable clamping of the tool or workpiece, it is suggested that the unit (60) for generating a clamping force have a supporting element (90) with a supporting surface (92), an actuator element (70) with a pressure surface (76) and a wedging element (80) which can be moved into an intermediate space (94) between the supporting surface (92) and the pressure surface (76) as a result of movement in an entry direction (96) from a release position into a pressure position in order to displace the actuator element (70) away from the supporting element (90) from a fir
