A method for processing a constructed, liquid-cooled piston of an internal combustion engine, the piston including an upper piston part and a lower piston part, which are supported by a joining plane and are connected to each other in a bonded manner. An electrochemical method, such as electrochemical machining, is used to produce a passage opening or a hole in the piston. By means of the method, material is selectively removed after the completion of the upper part piston, the lower piston part, or the piston after the two piston parts have been joined. The electrochemical machining allows an arbitrarily geometrically designed topography having at least one passage opening, a hollow, or an oil pocket in cooling areas or non-cooling areas to be created on the piston.
A method for processing a one-piece or an assembled, liquid-cooled piston of an internal combustion engine that includes a piston upper part and a piston lower part, wherein, to produce a passage opening or an aperture in the piston, electrochemical machining is used, characterized in that after the respective completion of the piston upper part, the piston lower part or the piston, removing selected material by electrochemical machining to create an arbitrary geometrically shaped topography configured as at least one of a passage opening, an oil drain aperture, a recess or an oil pocket in one of cooling areas and non-cooling areas in or on the piston.
