The present invention relates to a machine tool 100 for machining a workpiece 12 by means of a tool 22, which comprises a clamping means 11 for clamping the workpiece 12 and a support means 21 for receiving the tool 22, wherein the clamping means 11 is mounted on a spindle head of a clamping means-carrying work spindle 10 and the support means 21 is mounted on a spindle head of a support means-carrying work spindle 20, and the machine tool 100 is designed to position the two work spindles 10, 20 by means of numerically controllable axes in relation to one another in such a way that the workpiece 12, which is clamped in the clamping means 11, can be processed by the tool 22, which is received in the support means 21.

A spindle arrangement for a machine tool, comprising a spindle for driving a tool and at least one actuator for exciting vibration of the tool, characterized in that the spindle arrangement is provided with a compensation device for at least partly compensating the inertia forces produced by the vibration excitation in the spindle region.

A machine tool comprises a tool spindle which can be positioned in 3 axes and a pivot bridge pivotable about an A axis with a round table for mounting a workpiece pallet supporting a workpiece. Furthermore, in front of the pivot bridge, a mount is provided for a processed workpiece or workpiece to be processed located on a workpiece pallet. Between the mount and the pivot bridge a pallet changer is provided which can only perform a vertical displacement movement and a pivot movement about a vertical axis. Workpiece pallets are picked up and put down only during the vertical displacement movement of the pallet changer, or possibly by pivoting the pivot bridge about the A axis.
