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.
