Abstract
A method for the manufacture of piston rings, includes the steps of producing a tube and machining the desired ring free shapes on the inner and outer diameters of the tube providing desired cross sectional profiles by grinding, for example, and then cutting the individual rings from the tube. The ring gaps are preferably formed after cutting the ring from the tube. Coatings on the ring outer surface may be applied and shaped while in tube form.
