A method of machining a work-piece formed of titanium-based material, using a machining apparatus, is described. The method includes the steps of providing an electrically-conductive electrode contained within a spindle assembly, in a pre-selected distance and position relative to the titanium-based work-piece; while electrically powering the electrode and the work-piece with a power supply. In the process, fluid electrolyte is circulated through at least two pathways in the machining apparatusan internal conduit within the spindle assembly; and an external conduit. The charged electrode is moved relative to the work-piece in a plunging motion, to remove material from the work-piece at a relatively high rate, using a high-speed electro-erosion (HSEE) process.

An apparatus for an electrochemical discharge machining process is provided. The apparatus includes a holder housing having, an inlet hole, an outlet hole, a first side, and a second side, and containing an electrolyte, a tool holder disposed at the first side, and a first electrode having a first end and a second end. The holder housing is configured to sealingly accommodate the electrolyte unless at least one of the inlet hole and the outlet hole is open. The first end is coupled to the tool holder and the second end passes through the second side. Since the apparatus is moved to a machining position of the work-piece by a worker, additional power for controlling the position thereof is not necessary. In addition, the apparatus is easy to carry and use because of its simple structure.

An electro discharge machining system, and manufacturing method therefor, including: providing an electro discharge machining unit and control; providing a workpiece holder; providing a tool holder for a tool having an electrode array; and operatively connecting the workpiece holder and the tool holder to the electro discharge machining unit and control for batch electro-discharge machining of a workpiece to a configuration compatible with the electrode array.

An electrochemical machining device improves a roughness of a machined surface while keeping a relative scanning speed of a tool electrode with respect to a workpiece low. A power source applies a voltage, for making current for electrochemical machining flow, between a tool electrode and a workpiece. The tool electrode is arranged apart from the workpiece and is capable of being scanned relatively along a surface direction of the workpiece. An electrolytic solution supply section supplies electrolytic solution for electrochemical machining between the tool electrode and the workpiece. The charge control means eliminates an electrical charge that has accumulated between the tool electrode and the workpiece using an appropriate method.
