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: The present disclosure provides an electrochemical machining apparatus including a pressurized tank, a cap, a stabilizing plate, a guiding element, and an electrode. The pressurizing tank has a top surface and a chamber, wherein the top surface is disposed with an opening and a limiting portion. The cap fits in the opening and is limited by the limiting portion to seal the pressurized tank. The stabilizing plate is spaced from the top surface or the cap by a distance. The guiding element penetrates the stabilizing plate to connect with the cap and provides a channel to the chamber. The electrode is guided by the guiding element and penetrates the chamber via the channel. When the electrode processes a workpiece in the chamber during an electrochemical machining operation, the cap takes a pressure generated during the electrochemical machining operation, and the stabilizing plate stabilizes the electrode and the guiding element.

Abstract: A composite manufacturing method with extruding and turning process for extruding and turning a workpiece includes a clamping step, an isolating step, an extruding step and a turning step. The composite manufacturing method is used for manufacturing a surgical instrument. The clamping step is for positioning a clamping portion of the workpiece by a lathe chuck of the lathe apparatus. The isolating step is for blocking a lathe extruding force via an isolating portion of an extruding apparatus. The extruding step is for extruding a processing end portion of the workpiece by the extruding apparatus and generating the lathe extruding force transmitted toward a clamping portion of the workpiece. The turning step is for turning the processing end portion of the extruded workpiece by a lathe apparatus. The extruding apparatus is disposed on the lathe apparatus.
