Roll body for a hydrostatic rolling tool and hydrostatic rolling tool with the roll body

Abstract

A roll body for a hydrostatic rolling tool includes a center, an axis of rotation running through the center, and a machining zone for rolling a workpiece. The roll body is rotatable about the axis of rotation and the machining zone has a working profile line formed in a cross-section of the roll body. The working profile line has a first working arc extending around a first machining center and a second working arc extending around a second machining center. The first machining center is arranged offset to the center, and the second machining center is arranged offset to the center and offset to the first machining center. In an example embodiment, the roll body has a parallel to the axis of rotation, the first machining center lies in the cross-section on the parallel, and the second machining center lies in the cross-section on the parallel.
