The invention relates to a machine tool as well as to a method for operating the machine tool. The machine tool comprises a workpiece carrier (20) that can be incrementally rotated about an incremental advance axis (22) and has several carrier sides (25). A first workpiece chuck unit (26) for holding a workpiece in a first position (P1) and a second workpiece chuck unit (27) for holding a workpiece in a second position (P2) are arranged on each carrier side (25). In each angular position or incremental advance position of the workpiece carrier (20), one carrier side (25) is in a loading station (30), one carrier side (25) is in an unloading station 31, and the respectively other carrier sides (25) are in respectively one work station (32). A workpiece changing device (34) is provided, said device moving a partially machined workpiece (16a) out of the first position (P1) in the unloading station (31) into the second position (P2) in the loading station. The position change of the partially machined workpiece (16a) preferably also takes place during the incremental advance movement of the workpiece carrier (20). Preferably, the partially machined workpiece (16a) can be turned in doing so.

The atomizer of the electronic cigarette is successively conveyed for processing among such mechanisms.

A manufacturing apparatus (2) for components (3), which has at least one movable loading station (20) designed as a tool magazine (13) and having reception points (39) with different tools (4, 5, 6, 7) for different component types A-I. The loading station (20) is connected to one or more machining stations (20, 22) at which at least one machining device (23) and at least one handling device (24) for handling and releasing the components (3) from the tool (4, 5, 6, 7, 8) are arranged. The selected Figure is FIG. 5.

In an embodiment, a machine tool includes two fixed modules and two movable modules each of which having a main spindle, a headstock, and a tool post being integrally formed, and a bed on which these are installed. The movable modules are provided on the bed to be movable in the Y-axis direction, the fixed modules are fixed on the bed on the opposite sides of the these movable modules, and a recess is provided next to the fixed module, the recess being formed by cutting out the bed. The movable modules are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle of the fixed module or the fixed module. The movable module is movable to the opposite position of the recess.

A machine tool includes a spindle equipped with a workpiece gripping portion arranged so as to face an operator side, the spindle being configured to rotatably drive a workpiece gripped by the workpiece gripping portion, and a tool mount equipped with a rotary member supporting a plurality of tools in a rotatably indexable manner about an axis parallel to an axis of the spindle. The tool mount is arranged at a tool mount installation portion formed to be positioned on the operator side in a manner such that the rotary member faces a workpiece gripping portion side.
