Abstract

Processing tool for processing a surface of a workpiece. The processing tool includes a tool body which defines a tool axis. At least one first roll element, which is borne by the tool body, is rotatable around a first roll element axis and has a first outer surface with a rough surface structure in at least one first working section configured for rolling contact with the workpiece surface. Further, at least one second roll element, which is borne by the tool body, is rotatable about a second roll element axis and has a second outer surface that, in at least one second working section configured for a rolling contact with the workpiece surface, has a distance (r2) to the tool axis, which is less than a distance (r1) of the at least one first working section to the tool axis.
