A face turning head for machining stations, comprises a drive mechanism for displacing the tool slide transversely. A drive shaft drives a worm gear or its equivalent through a transmission element, such as a cog belt transmission to axially displace a setting rod. This axial movement of the setting rod, which is independent of the rotation of the turning head but can be effected simultaneously therewith, actuates a gib key drive by which a tool slide is displaced transversely to the turning head axis. Through reversing rollers and displaceable blocks, the centrifugal disequilibrium caused by the tool slide movement is compensated for. |
