Abstract: A method for shortening one or more rotor blade(s) (2) of a turbomachine (3) by removal of material at the blade tip, and apparatus (1; 19) for carrying out the method: a belt grinding apparatus (1; 19) shortens the rotor blades (2) and a contour of the blade tip is generated by a relative movement of the blade tip along the static belt grinding apparatus.
