Abstract
In order to improve a machine tool comprising a machine frame, a drum arranged for rotation about a drum axis within a maximum angular range in relation to the machine frame and having a plurality of machining devices held on it and drives rotatable with the drum and associated with the machining devices, a stationary control and supply device for the drives and a rotary supply unit which has line systems connected, on the one hand, to the rotatable drum as well as, on the other hand, held so as to be stationary in relation to the machine frame, these line systems being free from interruptions, deformable as a result of rotation of the drum and extending in the direction of the drum axis, in such a manner that the spatial requirements for the twistable line systems in the direction of the drum axis are as small as possible it is suggested that the line systems extend into a passage in the drum close to the drum axis.
