Abstract

A method for manufacturing gear wheels, specifically transmission gear wheels, is disclosed. An embodiment of the method includes the following steps: a) preparation of a base body for a gear wheel, b) electrochemical processing of the base body by a precise electrochemical machining process (PECM process), where several recesses running between the teeth of the gear wheel are made simultaneously electrochemically to manufacture the teeth of the gear wheel.
