The machine tool has a machine bed (10) having a first horizontal linear guide (1) and a second horizontal linear guide (2) arranged at right angles to the first linear guide (1). On the first linear guide (1) is arranged, in an axially displaceable manner, a workpiece clamping fixture (3), which is swivelable about a swivel axis (4) oriented parallel to the second linear guide (2) and is rotatable about a rotation axis (5) oriented at right angles to the swivel axis (4). On the second linear guide (2) a toque motor driven swivel arm (6) is axially displaceable, the swivel axis (7) of which is arranged parallel to the first linear guide (1) and which on its free end bears a tool spindle (8), the axis (9) of which is oriented parallel to the first linear guide (1).
Machine tool comprising a machine bed (10) having a first horizontal linear guide (1) and a second horizontal linear guide (2) arranged at right angles to the first linear guide (1), wherein on the first linear guide (1) is arranged, in an axially displaceable manner, a workpiece clamping fixture (3), which is swivelable about a swivel axis (4) oriented parallel to the second linear guide (2) and is rotatable about a rotation axis (5) oriented at right angles to the swivel axis (4), wherein on the second linear guide (2) a swivel arm (6) is axially displaceable, the swivel axis (7) of which is arranged parallel to the first linear guide (1) and which on its free end bears a tool spindle (8), the axis (9) of which is oriented parallel to the first linear guide (1), characterized in that the swivel arm (6) is swivelable by means of a torque motor disposed on its swivel axis (7).
A swivel arm (6) for a machine tool comprising, a machine tool which is swivelable about a swivel axis (7) and bears on its free end a tool spindle (8), characterized in that the swivel arm (6) is directly drivable by means of a torque motor (19, 20, 21), and a slide bearing (22) acting between the stator (20) and the rotor (21) is arranged with oil damping.
