In a method of thread rolling a screw shaft, an inclining portion 1c is formed to the boundary between the machining portion 1a of a screw shaft material 1 and the non machining portion 1b thereof as well as a taper portion 2b is formed to screw groove forming dies 2, by which a machining load concentrating at the thread rolling portion on the end of the dies on a chuck side can be reduced. With this method, the screw shaft can be thread rolled to have straightness of high quality.

En vertu d'une méthode de filetage par roulage d'un noyau de vis, un segment incliné 1c est formé à la frontière entre la portion d'usinage 1a d'un noyau de vis et la portion qui n'est pas à usiner 1b de ce dernier, et une forme conique 2b est donnée à une partie des outils de formage, ce qui permet de réduire la charge d'usinage appliquée à l'extrémité des outils de formage, côté mandrin. Grâce à cette méthode, il est possible de fileter par roulage des noyaux de vis avec une grande précision.
