Improvements in or relating to methods of grinding blade tips of turbine/compressor rotors.

摘要

The disclosure relates to a method of grinding blade tips of a turbine or compressor rotor, comprising the steps of spinning a rotor having one or more sets of blades to be ground on its axis, and using a grinding wheel which is narrower than the blades to be ground and has a convexly curved grinding periphery as seen as cross section. The grinding wheel is rotated about an axis parallel to the rotor axis and the wheel and rotor are moved relative to one another parallel to the axes of the rotor and wheel and in a feed direction orthogonally to the axis of the rotor and wheel to grind the blade tips of the rotor to a required dimension and profile which may be flat, angled, convexly or concavely curved with a simple or complex curvature.
