Method for machining the rotor of a turbine and device useful for carrying out the method

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...

Beschreibung
Zusammenfassung:	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.
