Apparatus for facing and internal turning

摘要

An apparatus for facing and internal turning, comprising a rotating housing and at least one carriage bearing a cutting tool and being displaceable transversely to the axis of rotation, has a drive motor in the rotating housing for displacement of the carriage and a distance measurement mechanism for directly measuring the distance of displacement of the carriage in relation to the housing, measurement and supply lines hereby extending between rotating housing and a stationary evaluation and control unit and the measurement signals and energy supply being transferred at a transfer unit from those parts of the measurement and supply lines communicating with the rotating housing to those parts of those lines communicating with the stationary evaluation and control unit.
