摘要： A machining apparatus which is designed for machining the outer circumference of a rotor, in particular of a gas-turbine or steam-turbine rotor, includes a plurality of separate carriages, at least one tensioning strap, wherein the carriages can be connected to one another to create an annular arrangement, and also having a tensioning device, in particular in the form of a pressure ratchet, which is designed for tensioning the tensioning strap. The carriages are each provided with preferably floating-mounted wheels, which are oriented in a direction of travel, and wherein at least one carriage has a tool carrier for accommodating a machining tool and driving it by motor. A method for machining the outer circumference of a rotor by using such a machining apparatus is provided.

摘要： 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.
