Highly flexible machine tool

A machine tool (1), in particular for metal-cutting machining of workpieces (22, 22′), comprising:

• at least two devices (8, 9) for receiving workpieces, which devices each have at least one carrier (16, 16′, 116, 116′), which is pivotable about a pivot axis (S) and which is provided with a workpiece receptacle device (21, 21′);
• wherein each carrier (16, 16′, 116, 116′) is assigned a positioning unit (23, 23′), by means of which the carrier (16, 16′) is pivotable about the pivot axis (S) to different positions and is fixable in a respective position;
• at least one first machining unit (13), which has at least one first work spindle (11), which can be driven to rotate about an axis of rotation;
• a first guiding and adjusting device (30), by means of which the work spindle (11) is adjustable at least in a positioning direction (Z) that coincides with the axis of rotation and in a lateral direction (X) oriented parallel to the pivot axis (S);
• wherein the adjustment travel of the first guiding and adjusting device (30) in the lateral direction (X) parallel to the pivot axis (S) is dimensioned to be long enough that a tool, secured to said at least one first work spindle, can be brought selectively into engagement with the workpieces (22, 22′) of the two workpiece receptacles (8, 9);
• wherein each carrier 116, 116′ has two workpiece receptacle devices (121a, 121b);
• and
• wherein said at least one first work spindle in the first machining unit comprises at least one pair of spindles (141).

• and
• wherein the carriers (16, 16′) of the workpiece receptacle (8, 9) are embodied in the shape of a U and are disposed side by side and have two legs (18, 19;
• 18′, 19′) joined together at ends thereof via respective crosspieces (17, 17′), on which the workpiece receptacle device (21, 21′) is disposed;
• and that the ends of the legs (18, 19;
• 18′, 19′) remote from the crosspiece (17, 17′) are connected to a positioning unit (28, 28′) that defines the pivot axis (S), and the pivot axes (S) of the two carriers (16, 16′) coincide.
