Working principle and classification of EDM drilling machine
Punching EDM machine: also known as electric spark piercing machine, punching machine, small hole machine, and EDM hole drilling machine, its working principle is to use a thin metal copper tube (called electrode wire) that moves continuously up and down vertically as an electrode to process the workpiece. Erosion of metal forming by pulsed spark discharge. Different from wire electric discharge machine tools and forming machines, the electrode of its electric pulse is a hollow copper rod, and the medium passes through the fine hole in the middle of the copper rod hole, which plays the role of cooling and chip removal. The discharge between the electrode and the metal generates high-temperature corrosion of the metal to achieve the purpose of perforation. It is used to process the pores of superhard steel, hard alloy, copper, aluminum and any conductive substance. It can process a small hole with a minimum of 0.015mm, and can also process a small hole with a taper. It is widely used in precision mold processing. It is generally used as a supporting equipment for WEDM machines. Silk hole, chemical fiber spinneret, spinneret hole of spinneret, filter plate, group holes of sieve plate, engine blade, cooling hole of cylinder body, oil circuit and air circuit hole of hydraulic and pneumatic valve body, etc. the
Punching machine (EDM drilling machine) is roughly divided into two types according to the different media used. One is liquid piercing machine. Since the liquid needs to pass through the small hole of the copper rod during processing, it may block the small hole of the copper rod, so the minimum processing size is 0.15mm. pores! The depth can only be processed to 20mm. It is widely used, and the other is a gas piercer. The medium passing through the small holes of the copper rod is gas, so it is not easy to be blocked, and more precise small holes can be processed!
