Abstract
Machining ball tracks and guiding webs of an inner part for a constant velocity joint in a clamping arrangement includes mechanical machining of at least one first ball track in a first rotational position; rotating the articulated inner part into a second rotational position for machining at least one further ball track; wherein at least one guiding web is mechanically machined during the rotating of the inner joint part from the first rotational position into the second rotational position. A corresponding device is used for machining ball tracks and guiding webs of an inner joint part.

A method for machining ball tracks and guiding webs of an inner joint part for a constant velocity joint in one clamping, comprising:
- mechanically machining at least a first ball track in a first rotational position;
- and
- rotating the inner joint part into a second rotational position for machining at least a further ball track;
- wherein at least one guiding web is mechanically machined during the rotation of the inner joint part from the first rotational position to the second rotational position;
- and
- wherein the guiding webs are machined by a web machining tool with a machining contour which rotates around an axis of rotation that extends radially to a longitudinal axis of the inner joint part.
A device for machining ball tracks and guiding webs of an inner joint part for a constant velocity joint in one clamping, comprising:
- a clamping unit for clamping an inner joint part with a longitudinal axis coaxially to a clamping axis A;
- a setting unit for gradually rotating the inner joint part about the clamping axis from one rotational position to the next;
- a rotationally drivable track machining tool for mechanically machining the ball tracks in respective rotational positions of the inner joint part;
- and
- a rotationally drivable web machining tool for mechanically machining the guiding webs;
- wherein the track machining tool is arranged in the circumferential direction relative to the web machining tool such that the guiding webs of the inner joint part are respectively machined upon rotation from one rotational position of the inner joint part to a next rotational position;
- and
- wherein the web machining tool is rotationally drivable about an axis of rotation that is radial relative to the longitudinal axis of the inner joint part, and wherein the web machining tool has a machining contour which is configured to mechanically machine at least one web face when the inner joint part is rotated from one rotational position to the next rotational position.
