Abstract: A machining unit for a machine tool and machine tool having such a machining unit comprises a head carrier that is attached to the machine tool, a pivot head held on the head carrier in such a way that the pivot head can be pivoted about a pivot axis, a working spindle, which is arranged on the pivot head and has a spindle axis that is tilted in relation to the pivot axis, a spindle motor, which is arranged in the head carrier and has a drive shaft arranged parallel to the pivot axis, and a drive transmission for transmitting the rotational motion of the drive shaft of the spindle motor to the working spindle, wherein the drive transmission has a transmission stage that can be shifted. The pivot head has a shifting transmission shaft that is oriented coaxially to the pivot axis of the pivot head, wherein the transmission stage that can be shifted has a hollow shaft movably supported on the shifting transmission shaft of the pivot head.

Abstract: A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in an X-direction which is perpendicular to the Y-direction and Z-direction.

Abstract: 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.
