METHOD OF ELECTROCHEMICAL DIMENSIONAL PROCESSING BY A ROTATING ELECTRODE WITH THE EXCENTRICE OF THE WORKING SURFACE Russian patent published in 2017 - IPC B23H3/00 B23H3/04 B23H7/22 

FIELD: electricity.

SUBSTANCE: method uses a rod electrode tool comprising a cylindrical holder with a central channel for supplying an electrolyte to the working part of an electrode tool made with eccentricity relative to the longitudinal axis of the holder, while on the surface of the working part from the side of the maximum eccentricity of the working surface from The longitudinal axis of the holder is provided with a longitudinal side groove for pumping the electrolyte, which also communicates with the central channel for supplying the electrolyte. The working part of the electrode-tool has a cylindrical or semispherical shape. In the method of the rod electrode-tool, rotational movement about its longitudinal axis and feeding is set and performed relative to the workpiece, is moved on the set coordinates of the curved surface of the part and is supplied to the electrode-tool technological current pulses with predetermined duration and frequency when the minimum gap between the surface of the working part elektrode- tool and workpiece surface in the direction of movement of the electrode-tool. At the time of increasing interelectrode gap-vector perpendicular to the tool electrode movement along a curved trajectory washed dissolution products. Moreover, the process of the current pulse frequency set multiple frequency rotational motion of the electrode-tool, and a current supply process is synchronized with the direction of movement of the working part of the tool-electrode.

EFFECT: invention makes it possible to improve the accuracy of the 3-dimensional finish machining over the entire surface of the workpiece.
