EDM is an English abbreviation is WEDM (WEDM-LS) is the use of a continuously moving thin wire (called a wire) as an electrode, the workpiece pulse spark discharge erosion metal, cut type. It is mainly used for processing a variety of complex shapes and precision small parts, depending on the electrode wire material (molybdenum wire, one is copper wire), Wire EDM is usually divided into two categories: one is slow go wire (electrode wire is copper) wire as the low one-way movement, generally take the wire speed is less than 0.2m / s, accuracy of 0.001mm level, close to the grinding surface quality level. Wire no longer in use after discharge, smooth, uniform, small jitter, better processing quality. And the use of advanced power technology to achieve high-speed processing, maximum productivity of up to 350mm2 / min. I plant: threaded plug, threaded ring, smooth Cypriot ring, smooth ring gauge, calipers, sine, Mohs gauge, various test rods, cylindrical Square, square boxes, flat, V-shaped frame, granite slab, flat feet parallel to the regulation, rectangular device, square boxes and other non-scalar gage.
