Claims

[Scope of utility model registration request]

Rolling involves forming grooves by plastic working on the outer circumferential surface of a workpiece by pressing a plurality of rolling dies onto the outer circumferential surface of the workpiece, which has a circular outer circumferential surface and is fixed by a clamp mechanism. is a groove processing machine according to the present invention, in which protrusions for forming the grooves are formed on the outer peripheral surface of some of the plurality of rolling dies over the entire circumference, and the remaining A groove processing machine by rolling, characterized in that the above-mentioned protrusions are not formed on the outer peripheral surface of the rolling die.
