Abstract: An electrochemical machining apparatus for forming turbine blades includes a main base, an upper seat and an electrode unit. The main base includes a working platform for allowing a turbine blade to be placed thereon. The working platform includes an upper step stage for resisting the turbine blade, and a lower step stage for keeping a predetermined working space from a portion of the turbine blade desired to be cut. The main base has a guiding channel for allowing an electrolyte to flow through the predetermined working space. The upper seat is configured to cover above the main base and to contact one side of the turbine blade to form an electrical connection. The electrode unit includes an anode electrode electrically connected to the upper seat and at least one cathode electrode disposed on the main base.

Abstract: An electrochemical machining apparatus with a clamping device and an electrode aligned in the same direction includes a platen, a lower seat, an anode electrode and a cathode electrode. The platen and the lower seat are located relatively for clamping. A working space is formed between the platen and the lower seat for allowing a workpiece to be placed therein. The anode electrode is disposed on the platen and is electrically connected to the workpiece. The cathode electrode is disposed inside the lower seat and is corresponding to the working space. An isolation layer is disposed between the cathode electrode and the lower seat to avoid an electrical connection. A working gap with a constant distance is preserved between the cathode electrode and the workpiece for allowing an electrolyte to flow therethrough and performing electrochemical machining.
