Abstract

See full text

A method for producing a groove structure in an internal surface of a pin bore of a piston may include providing a rotatable boring bar with at least one cutting tool; advancing the boring bar while rotating at a first rotational speed in a direction of rotation with a first feed speed into the pin bore and introducing at least one helical first groove of the groove structure with a first depth and a first width into the internal surface; and retracting the boring bar, subsequent to introducing the at least one helical first groove, from the pin bore with a second feed speed while maintaining rotation at a second rotational speed in the direction of rotation; during the retracting of the boring bar at least one helical second groove is introduced into the internal surface.
