Patent ID: 6998563

Claim:
A carbon nanotube apparatus for surface discharge polishing comprising: a signal generator having an integrated circuit for generating square wave, the signal generator using a transistor to control a external processing voltage to turn on and off to precisely control the energy in electrical discharge machining; a photo coupler for isolating a first electrode of the apparatus and a second electrode for processing to prevent a circuit comprising the first electrode from being damaged due to various factors; an electrical discharge machining area comprising: a cathode being the first electrode having more than one carbon nanotubes grown on it; and an anode being the second electrode for placing a target fixed on the anode; and a current limiting resistor for controlling a current value for carbon nanotube tips of the cathode for electrical discharge machining; wherein the signal generator controls the cathode for generating a waveform of square wave for electrical discharge machining and to control a current value for carbon nanotube tips for electrical discharge machining, thus to enable the cathode for nanometer-level micro machining.
