    摘要: 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.
