摘要： A method for machining a gas turbine rotor which is provided with a cooling air slot which concentrically extends around the axis of the gas turbine rotor and is supplied with compressed cooling air via axial cooling air holes which at the side lead into the slot base of the cooling air slot, and the opening of which is covered by bridges which are arranged in a distributed manner over the circumference and spaced apart from each other by gaps. A crack-resistant slot shape is achieved without intervention into the configuration of the bridges by a material-removing tool, particularly a milling tool, being lowered in the gaps between the bridges one after the other into the cooling air slot and in this way the slot base of the cooling air slot being machined and widened over the entire circumference.

摘要： In a method for machining grooves, especially fir-tree grooves (13), which are provided for accommodating blades (19), on a rotor (10) of a turbine, especially a low-pressure steam turbine, great simplification and high flexibility is achieved by the fact that in the grooves, or fir-tree grooves (13), material is removed by a program-controlled milling device, wherein the milling device is inserted into the groove, or fir-tree groove (13), with a milling tool (20) which is guided along the places in the groove, or fir-tree groove (13), which are to be machined, by a milling tool positioning device, which is freely movable in space.

摘要： A method for converting a turbine casing of a turbine having an axial flange relative to a rotational axis of a rotor of the turbine, and having a radial hot gas inlet relative to the rotational axis includes the steps of: axially separating the turbine casing into two axial sections so as to form a separation zone, wherein the first axial section has the flange and the second axial section has the hot gas inlet; rotating the two axial sections relative to each other around the rotational axis so as to transfer each of the two axial sections from an original old relative position into a new relative position; and connecting the two axial sections to each other in the new relative position along the separation zone.
