<p>A cutting process S1 cuts a wire 1 into cut pieces each having a volume approximately equivalent to that of a desired shoe 11. A forging process S2 sequentially forges cut pieces 2 with forging dies 13, 23, and 33 having three cavities 13c, 23d, and 33e respectively, and obtains a steel sphere 8. A finishing process S3 obtains a shoe-shaped material 10 from the steel sphere 8 without a heat treatment, and carries out a heat treatment to the obtained material 10, thereby to obtain a shoe 11 for a compressor. <??>Based on the above processes, it is possible to shorten the manufacturing time of the shoe for a compressor, and it is also possible to reduce the cost of manufacturing this shoe. <IMAGE></p> |
