Abstract:
There is provided a method for processing a raceway groove configured to circumferentially form a to-be-processed side raceway groove on a surface to be processed of a workpiece, the to-be-processed side raceway groove is configured to be brought into rolling contact with a rolling element, and the surface to be processed is a cylindrical circumferential surface. The method for processing a raceway groove includes: arranging a processing rolling element rotatably between the to-be-processed side raceway groove and a tool side circumferential surface which is opposed to the surface to be processed and which is a cylindrical circumferential surface of a machining tool; rotating the machining tool relatively with respect to the workpiece; and performing a burnishing process on the to-be-processed side raceway groove.

Claim (Index 2):
A method for processing a raceway groove configured to circumferentially form a to-be-processed side raceway groove on a surface to be processed of a workpiece, the to-be-processed side raceway groove being configured to be brought into rolling contact with a rolling element, and the surface to be processed being a cylindrical circumferential surface,\n wherein the workpiece is a ball nut for a ball screw device which is spirally provided, on an inner circumferential surface of the ball nut as the surface to be processed, with an outer diameter side ball screw groove which is the to-be-processed side raceway groove and which has a partial circular arc shaped cross section, a machining tool is a mandrel which outer circumferential surface is the tool side circumferential surface, and the method for processing a raceway groove, further comprises: arranging a processing ball as a processing rolling element rotatably between the outer diameter side ball screw groove and the tool side circumferential surface of the mandrel which is opposed to the inner circumferential surface of the ball nut; rotating the mandrel relatively with respect to the ball nut, and displacing the mandrel in an axial direction relatively with respect to the; and performing the burnishing process on the outer diameter side ball screw groove, wherein the outer circumferential surface of the mandrel is spirally provided with a tool side ball screw groove having a partial circular arc shaped cross section.
