摘要:
An electrode applied in electro-machining processes is provided. The electrode comprises a main body portion and at least one built-in internal flushing passage for introducing a flushing liquid to a volume between the electrode and a workpiece to be machined. The electrode is made by an additive fabrication process that enables specialized flushing for enhancing waste material evacuation and incorporate special material properties like zones of high electrical conductivity and thermal resistance. The fabrication process produces materials and geometries that could not otherwise be made using conventional processing.
摘要:
A deposition is gradually formed by molding a product main body, removing a defect periphery including a defect generated on a surface to be treated of the product main body by molding so that a recess portion is formed on the surface to be treated of the product main body, employing a molded electrode composed of a molded body molded from a powder of a metal or the molded body processed with a heat treatment, and generating a pulsing electric discharge between the recess portion periphery including the recess portion and the molded electrode in an electrically insulating liquid or gas so that a material of the molded electrode or a reaction substance of the material carries out deposition and such at the recess portion periphery by energy of the electric discharge.
摘要:
What is described is a method for machining a metallic piece (1) by electroerosion, achieved by generating discharges of electrical current through a conductive liquid medium (3) between the piece (1) itself and an electrode (2) positioned at a predetermined operating distance therefrom. The method according to the invention uses a liquid electrode (2) consisting of the said current-conducting liquid medium (3) contained in a capillary tube (4), this conductive liquid medium (3) being supplied continuously and with a flow rate equal to the quantity of liquid which is consumed to the free end (4e) of the said capillary tube (4) facing the workpiece (1).
