Patent ID: 7501049

Claim:
ECM machine for electrochemically machining metallic workpieces by anodic dissolution of the workpiece by utilizing an electrolyte and an applied dc voltage, comprising at least one revolving table for mounting the workpiece or a workpiece carrier, a portal with a transverse girder, at which one or two cathodes are provided, the at least one revolving table being rotatable about a vertical axis (A), the portal being movable linearly along a horizontal axis (D) of horizontal guides with respect to the revolving table, the transverse girder being movable vertically along a vertical axis (C) of vertical guides of the portal, the transverse girder being rotatable about a horizontal axis of rotation (E), and the cathode or cathodes being clampable each with one or with a common clamping device of the transverse girder, and movable along a horizontal axis (F,G) of a horizontal guide of the transverse girder.
