Abstract
A facing head includes a housing with a center axis and a rotary slide with a rotation axis offset from the housing center axis. At least one cutter plate is provided on the rotary slide and rotatable therewith. A centrifugal drive is located in the housing which rotates the rotary slide about its axis of rotation. The centrifugal drive includes at least two driving bodies which are mounted within the base body of the facing head and which are displaceable essentially perpendicular to the center axis under the influence of centrifugal force. The rotary slide rotates under the influence of a spring return device when centrifugal force does not move the driving bodies outward. A coupling device in the form of a gear wheel on the rotary slide co-operates with racks on the driving bodies so that the driving bodies move together but in opposition.
