Abstract
In order to improve a machine tool comprising a tool carrier with a tool carrier head which is mounted for rotation about an axis and has a support member with a plurality of tool receiving means, into which drivable tool units can be inserted such that gear wheels for driving all the tool units insertable into the tool receiving means are arranged and can be moved in an interior of the support member on an orbital path extending around the axis, in such a manner that some of the tool units can be driven selectively, it is suggested that a drive wheel be rotatable about a drive axis which is arranged non-coaxially in relation to the axis, that teeth of the drive wheel move on a flight path which extends such that in a drive section of the orbital path the distances between this and the flight path have the lowest values and are greater in all the other sections of the orbital path and that the teeth be in drive engagement with a gear wheel located in the drive section and extend without contact in relation to each gear wheel located outside the drive section.
