Abstract

The machine tool has a machine tool body (10) with a first horizontal linear guide (1) and a second horizontal linear guide (2) arranged at a right angle to the first linear guide (1). A workpiece holder fixture (3) is arranged on the first linear guide (1) in an axially displaceable manner, which workpiece holder fixture can be rotated about an axis of rotation (4) oriented parallel to the second linear guide (2) and about an axis of rotation (5) oriented at right angles to the axis of rotation (4). The rotary arm (6) is axially displaceable on the second linear guide (2), the axis of rotation (7) of which is arranged parallel to the first linear guide (1) and the free end of which carries a tool spindle (8), the axis (9) of which is oriented parallel to the first linear guide (1). The rotating arm (6) can be rotated by a torque motor arranged on a rotation axis (7) of the rotating arm.
