Abstract
Tip grinding of BLISK blades is performed in a static state of an incrementally rotatable BLISK, with a rotational axis () of a grinding wheel (), which is traversable along an upper edge of the blade, being aligned diagonally to an orientation of the blade upper edge, and hence, in a direction of maximum resistance moment of the blades. The apparatus for the performance of the method features a locating device () for a BLISK which is incrementally rotatable by an auxiliary drive () as well as a high-speed shaft () driven by a main drive () for blade tip grinding of conventional rotor wheels fittable to the high-speed shaft (). The grinding wheel () is traversable in Y-direction and rotatable about a center axis extending in X-direction, such that the blade tips in the static state can be ground in the direction of the maximum resistance moment of the blades.
