Mobile machine tool and method for segmentally machining a component

A mobile machine tool for segmentally machining, in situ, a component which is rotatable about an axis of rotation, in particular a component of a turbine, comprising:

• a base body, on which fastening means are provided for releasably mounting the base body on a body which is stationary relative to the axis of rotation and which defines the axis of rotation, in particular on a turbine housing,
• a carrier element, which is held on the base 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 carrier element and is designed to receive a tool, in particular a cutting tool, preferably a grinding wheel or a side milling cutter,
• wherein the tool module is arranged on the carrier element so as to be linearly adjustable transversely, in particular radially with respect to the C axis.
