Abstract
A method for roller burnishing a cylindrical component part surface of a workpiece includes using a roller burnishing tool including at least one rolling element. The at least one rolling element is pressed by hydrostatic pressurization radially outwardly against the component part surface and is left to roll down on the component part surface by rotating the roller burnishing tool or the workpiece. The torque arising as a result of the friction between the at least one rolling element and the component part surface is detected and sent for evaluation.
