Abstract (en)
[origin: EP2730370A1] The method involves removing a housing part exposing rotor blades (11) to be machined. A grinding device (1) is arranged in a region of a rotor blade to be machined such that a tip of the blade is machined by using a grinding disk (2) of the device. The machining region is screened off by arranging a screening device to counter a release of grinding dust from the screened-off region. Suction extraction is provided such that the extraction extracts the dust from the screened-off region. The tip of the blade is grinded in-situ for producing predetermined radial gap width. An independent claim is also included for a grinding device.
