Abstract
A method for chipless machining of a surface region of a rolling-element bearing ring includes rotating the rolling-element bearing ring relative to a first tool having a first tool tip and a second tool having a second tool tip, positioning the first and second tool tips at start positions at first and second opposite axial ends of the surface region, and moving the first and second tools in opposite axial directions such that the first tool tip follows a first helical or spiral path on the surface region and the second tool tip follows a second helical or spiral path on the surface region, the first and second paths crossing at multiple points within an overlap region located between axial ends of the surface regions.

A method for chipless machining of a surface region of a rolling-element bearing ring, the method comprising
- setting the rolling-element bearing ring in rotation relative to two tools, which each include a tool tip, and
- starting from different start positions at opposite axial ends of the rolling-element bearing ring, guiding the tool tips of the two tools over the surface region in opposite directions with respect to the surface region of the rotating bearing ring and pressing the tool tips against the surface region by a pressing force, so that on the surface region a helical or a spiral-shaped trajectory is formed by each tool tip such that the trajectories regionally overlap and cross each other multiple times in an overlap region.
A method for chipless machining of a surface region of a rolling-element bearing ring, the method comprising:
- rotating the rolling-element bearing ring relative to a first tool having a first tool tip and a second tool having a second tool tip;
- positioning the first tool tip at a start position at a first axial end of the surface region of the rolling-element bearing ring;
- positioning the second tool tip at a start position at a second axial end of the surface region of the rolling-element bearing ring opposite the first axial end;
- moving the first and second tools in opposite axial directions such that the first tool tip follows a first helical or spiral path on the surface region and the second tool tip follows as second helical or spiral path on the surface region, the first and second paths crossing at multiple points within an overlap region located between axial ends of the surface region,
- wherein the overlap region extends at least over a main loading zone of the surface region, and
- wherein the first start position and the second start position are outside the main loading zone.
