METAL MANUFACTURE METHOD AND APPARATUS USING LASER MASKING AND ELECTROCHEMICAL ETCHING

摘要

PURPOSE: A method and a device for processing metal using laser masking and electrolysis etching techniques are provided to manufacture the shape of metal with excellent precision rapidly through electrolysis etching after forming a mask using a laser beam. CONSTITUTION: A method of processing metal using laser masking and electrolysis etching techniques comprise next steps. A mask is formed on a part of the surface of a target(200) by the irradiating of a laser beam. The surface of the target is phase-transformed to form the mask. Mask-formed target is dipped in electrolyte, and power is supplied to the electrolyte. A non-mask part is etched. The mask is removed and cleaned.
