The invention relates to a method for producing a one-piece piston (1) for an internal combustion engine. Said piston comprises an annular cooling channel (6) which is arranged in the edge region of the piston head (4) and is partially closed by a surrounding projection (17) embodied as an oil groove. The inventive piston (1) is produced from a piston blank (22) in a simple and cost- effective manner, by means of machining, especially turning. |
