ABSTRACT:
Method for deburring and/or rounding a side face of a thin-sheet and annular metal element (1), such as a ring element (1) for use in a push belt for continuously variable transmission, wherein the ring element (1), in a machining step, is received in a device for electrochemical machining (“ECM”) of the ring element (1), an electrode (5) being positioned in the device opposite an axially oriented side face (3) of the ring element (1), which electrode (5), as seen in a thickness or radial direction of the ring element (1), has a dimension which is at least twice as great as a dimension of the ring element (1) in the said thickness direction.
