ABSTRACT:
An apparatus for the fine radial adjustment of a turning tool of a rotating cutter head with a first converter for converting a low pneumatic control pressure into a fluid pressure and with a further pressure converter for converting the intermediate pressure into a high working pressure for acting upon an adjusting medium, adjusts a turning tool. The first converter is stationary outside of the rotating head and is connected to the second converter, which is disposed in the rotating head, over a connection of conduits providing a rotary transmission for pressure transformation. The intermediate pressure is set higher than the control pressure, but lower than the adjusting pressure for unloading the rotary transmission.
