  • Method and device for setting a predetermined radial gap width for rotor blades of a turbomachine
    Patent number: 9969055
    Abstract: A method and device for setting a predetermined radial gap width for rotor blades arranged in a housing of a turbomachine is provided. The method includes removing a housing part and at least partially exposing the rotor blades which are to be machined, arranging a grinding device in the region of a rotor blade which is to be machined such that the tip of the rotor blade is machined using a grinding disk of the grinding device, screening off the machining region by arranging a screening device which is formed so as to counter a release of grinding dust from the screen off machining region, providing a suction extraction such that it extracts grinding dust from the screened-off machining region and grinding the tip of the rotor blade in situ producing the radial gap width.
