Abstract

A process of producing an inner joint part for a constant velocity plunging joint is disclosed. The process includes providing a preformed blank, hardening the preformed blank, hard-machining first track portions, while second track portions remain unmachined. The preformed blank includes a longitudinal axis, an outer face with circumferentially distributed tracks, a central through-aperture, a first end face and a second end face opposed thereto. The tracks each comprise a first track portion having, in a cross-sectional view, a smaller track radius and a second track portion having, in a cross-sectional view, a greater cross-section.
