摘要： PROBLEM TO BE SOLVED: To provide a method for producing a titanium compressor impeller of high precision where extensively fitted excess thickness is extensively removed as removal margins in a production process, thus dimensional accuracy upon working is increased, and, as the simplification or obviation in the correcting operation of a rotary balance is attained, and product yield is improved.
SOLUTION: The outer circumferential face of a front casting boss section 21 in a titanium casting is fixed by a chuck of a lathe. A plurality of receiving plates 4 projecting from the lathe side are located between respective casting blades 27, 28, and further, the tips thereof are pressed against the nose face 31 of a disk-shaped large diameter part formed at the second half part of a casting core section. With the nose face 31 of the large diameter part in the casting core section 23 and the outer circumferential face of the front casting boss section as standard faces, the titanium casting is held by the chuck and the receiving plates, so as to be rotated. The edge faces and outer circumferential face of a rear casting boss section 24, the back face and outer circumferential face of the casting core section, and the trailing edges of a casting full blade and a casting splitter blade are machined, thus the parts equivalent to the excess thickness of these regions are removed from the titanium casting.
