Abstract

In high-speed machines eg. CNC controlled for grinding rotor blades of jet engines and the like, the grinding head is a multiple head (1) which is provided with, at least, two grinding wheels (2) made from different materials and having different abrasive characteristics, which are intended for specific and suitable operational application to blades (4) of rotors (3), or the like, which have different metallic compositions, there being means for automatically selecting the grinding wheel (2) suitable for use as a function of the parameters of each grinding task, as well as means for actuating and operationally positioning said suitable grinding wheel (2) to be used, and each of said grinding wheels (2) having the corresponding profiling means available for restoration of the active surface of the grinding wheel (2).
