摘要： The present invention provides a manufacturing method of high precision titanium compressor wheel in which by removing pads attached on an entire surface entirely as a machining allowance in manufacturing process, dimensional accuracy at the time of manufacturing is intensified, and correction work of dynamic balance (rotation balance) is simplified or omitted so as to improve yield of products and suppress boosting of manufacturing cost. The outer peripheral face of a front cast boss portion of a cast titanium product is fixed with a chuck of lathe. A plurality of receiving plates projecting from the lathe are positioned between respective cast blades and front ends thereof are pressed against a disc-like large-diameter front end face formed on a rear half portion of a cast core portion. With a large-diameter front end face of the cast core portion and the outer peripheral face of the front cast boss portion as reference plane, the cast titanium product is held by the chuck and receiving plates and rotated. By turning the end face and outer peripheral face of a rear cast boss portion, the rear face and outer peripheral face of the cast core portion and trailing edges of cast full blades and cast splitter blades, portions corresponding to the pads at these portions are removed from the cast titanium product.
