The present invention relates to a machine tool for machining a workpiece, comprising a spindle arm with a spindle for receiving a tool or the workpiece, said spindle arm being movably attached to a spindle arm-receiving section that is arranged on a machine frame. The spindle arm comprises: a first spindle arm section hinged to the spindle arm-receiving section and designed as a longitudinal element and being pivotable about a first rotational axis with respect to the spindle arm-receiving section; and a second spindle arm section hinged to the first spindle arm section and designed as a longitudinal element and being pivotable about a second rotational axis with respect to the first spindle arm section. The spindle arm-receiving section comprises: a first subsection and a second subsection, arranged on the machine frame at a distance from each other to receive the spindle arm, the first subsection of the spindle arm-receiving section having a first braced drive for transmission of a first torque onto the first spindle arm section. The first spindle arm section comprises: a first subsection and a second subsection, arranged on the spindle arm-receiving section at a distance from each other to receive the second spindle arm section, the first subsection of the first spindle arm section having a second braced drive for transmission of a second torque onto the second spindle arm section. |
