Machining unit for machine tools with several machining stations with a tool spindle (4), which is accommodated longitudinally displaceably on the inside of a displacement unit (1) which consists of a hollow threaded spindle (5) and a threaded nut (6) with associated sleeve (8). The tool spindle (4) is mounted rotatably on the front side in the threaded nut but is not displaceable axially in relation to the threaded nut (6). On the driving side the tool spindle is formed as a slotted shaft (35) which is, for example, in a work connection with a hub-like toothed wheel (24) which is rotatably but not axially displaceably mounted in the body (2) of the machining unit (1). The threaded spindle (5) is mounted rotatably but not axially displaceably on the inside of the machining unit (1) and is drivable via a motor (23) which is drivable in both directions of rotation.
