Abstract
An apparatus for machining a circumferential surface defining a cylindrical bore of a workpiece, the apparatus including a tool holder rotatable about a first rotation axis, and a form roller supported on the tool holder so as to be rotatable about a second rotation axis parallel to a central axis of the cylindrical bore of the workpiece. The form roller has a diameter smaller than a diameter of the cylindrical bore of the workpiece and is adapted for forming a plurality of microscopic recesses on the circumferential surface defining the cylindrical bore of the workpiece.
