Patent ID: 7833086

Claim:
A method for alternatively grinding blade tips of rotor wheels in BLISK configuration and rotor wheel drums, comprising: providing a grinding wheel with a flat grinding surface rotatable about a rotational axis thereof, the grinding wheel traversable in a Z-direction longitudinally to the rotor wheel/rotor wheel drum and vertically to the to the rotor wheel/rotor wheel drum in a Y-direction; positioning the rotor wheel/rotor wheel drum so that an axis thereof is parallell with an axis of the Z-direction and making the rotor wheel/rotor wheel drum incrementally rotatable about that axis; adjusting the grinding wheel for height along the blade tips in the Y-direction and rotating it about an axis extending in an X-direction to adjust the grinding wheel in a direction of orientation of a blade upper edge, also rotating the grinding wheel about an axis extending in the Y-direction to adjust the grinding wheel to a cone of adjacent blade rows; individually grinding each blade tip in a static state in a direction of maximum resistance momentum of the blade along an upper edge of the blade and with the rotational axis of the grinding wheel being oriented diagonally to the blade upper edge; wherein the blade tips are ground each from a leading edge and from a trailing edge to a center of the upper edge of the blade.
