<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a rotor (10) of a centrifugal compressor produced from an integral structured disk at low cost, allowing obtaining the optimal dimensional accuracy meeting a corresponding expectation value. <P>SOLUTION: A disk has a radial cavity (12) formed within a rotor (10) by processing the disk in a radial direction in a manner to remove chip using at least a tool (29) of a value-controlling device. Since there is no distortion caused by welding, the optimal dimensional accuracy meeting design requirements can be obtained. <P>COPYRIGHT: (C)2004,JPO |
