A mobile machine tool for segmentally machining, in situ, a component, in particular a component of a turbine, which is rotatable about an axis of rotation. The machine tool has a main body, a support element which is held on the main body so as to be movable about a C-axis along a circular-arc-shaped guide path, and a tool module which is held on the support element and is designed to receive a tool. The tool module is located on the support element so as to be linearly movable. A method segmentally machines, in-situ, a component which is mounted in a stationary body so as to be rotatable about an axis of rotation.

Mobile machine tool and method for segmentally machining a component

Provided is a machining device for machining a rotor arranged in a turbine housing which includes two parts, thereby forming a joint, in situ while the upper housing half is removed. The machining device includes a main part that releasably secures the main part to the lower housing half in the region of the joint, at least one tool holder for receiving at least one machining tool which is secured on the main part directly or indirectly so as to be alignable relative to the main part, multiple telescopic stabilizing elements which can be locked into different longitudinal settings preferably in a continuous manner.
