Abstract
Apparatus for use in repairing turbine rotors includes a stand which supports a turbine rotor at positions spaced along its axis, the stand further including work stations to providing a work surface extending alongside a blade positioned in an array of blades on the rotor. A stop prevents movement of the rotor relative to the work station so that work operations can be carried out on a blade. The rotor may then be rotated about its axis until an adjacent blade is brought into proximity with the work station whereafter that blade may also be repaired and so on until all the blades have had the necessary repairs carried out thereto. The work surfaces may receive machine tools and other apparatus for the repair of the blades. A plurality of work stations may be provided enabling the simultaneous repair of a plurality of blades on the rotor thereby considerably decreasing the time necessary to carry out full repair to the rotor.
