Method of producing thin-walled bottomed cylindrical metallic member

摘要

There is provided a method of producing a thin-walled bottomed cylindrical metallic member that prevents (avoids) one end surface of a jig from abutting against a guide bush of a Swiss type automatic lathe during cutting, thereby preventing hindrance of feeding a work and the jig in the axial direction, resulting in enhancement of productivity. The method of producing a thin-walled bottomed cylindrical metallic member includes carrying out a hole forming process of forming, by cutting, a central hole in a work that is a solid round metallic bar having a long length and an approximately constant outer diameter along a central axis line of the work so as to form a bottomed hole having a bottom at a front end of the work; carrying out a wall-thickness thinning process of cutting the work to have a smaller outer diameter on a front end side of the work so as to thin a front end side of the work; and carrying out an installing process of, during the wall-thickness thinning process, inserting a [ filling member into the bottomed hole formed in the hole forming process, fixing to the work a jig that elongates one ; end side of the work, and has a reduced diameter portion ! extending in a predetermined distance from one end surface of the jig that is connected to the work, and mounting the jig to : a chuck of a lathe.
