| 摘要 |
The invention relates to a machining center provided with a workpiece machining tool. Said machine tool comprises: an essentially horizontal working plate (10) which is supported by a machine tool stand (2); a workpiece support (20) which is accommodates a workpiece (2) and which is placed on the working plate (10); a machining head (30) which accommodates a machining tool (29) and which is mounted on a vertical machining column (32) that can pivot around a vertical axis (37) by means of a rotary plate (36), said rotary plate being arranged underneath the working plate (10) and integrated in the machine stand (2), and; a first carrying arm (34) for the machining column (32). One end of said carrying arm is connected in a fixed manner to the rotary plate (36), and the other end is laterally guided out over the working plate (10) in such a manner that the machining column (32) mounted there can be pivoted around the working plate (10). A holding device is provided that comprises a bearing (33), which is arranged above the machining head (30) in the axial extension of the axis (37) of the rotary plate (36), and on which a second carrying arm (35) for the machining column (32) is mounted that is joined to said machining column (32).
