Abstract: 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.

Abstract: The method for the manufacture of wall connector pieces is based on a thin-walled tubular blank which is first reduced in diameter at least one, preferably both ends in order to increase the wall thickness. In this way, a basis is provided for further shaping, for example, the manufacture of a connector piece (4) or a closed end (5).
