The invention relates to a machine ( 1 ) for grinding the blades of a turbine rotor ( 2 ) or a compressor. The inventive machine consists of a rotary head ( 6 ) which is provided with two different grinding wheels ( 7, 7 ') for grinding the rotors ( 2 ), three carriages ( 8, 9, 10 ) of the head which are used for the linear and angular movement thereof, a machine control unit ( 16 ) comprising a numerical control (CNC) which is used to calculate the grinding position of each grinding wheel, an optical sensor ( 19 ) which is used to measure the radius R of the blades and a device ( 12, 13 ) for the individual shaping of each grinding wheel which is supported on a carriage ( 14, 15 ) with means for the linear movement thereof (U, C) and which operates automatically during the grinding process without altering the position of the grinding wheel.
