To electric spark and wire Introduction cutting
electric spark machine tool is a general designation, it is divided into electric spark forming machine tool and machine tool.
EDM machine is widely used in die machining. The two processing principle is the same, it is the use of positive and negative electrode contact discharge to produce high temperature melting metal, so as to achieve the purpose of cutting. Then how should the electric spark and wire cut be understood
electric spark can only? Process metal parts, and there is little cutting force in machining process, no special requirement to the hardness of the machining parts.
EDM machine tool used is generally divided into EDM, EDM and EDM punch. Mainly used for cavity forming electrode machining EDM Ma Chine, machining blind hole.
is the most commonly used electrode material for copper graphite, copper tungsten alloy, silver tungsten alloy can also be used as electrode materials but the cost is high.
machining almost no cutting force, the quenching material has no effect on the processing, generally used as semi finishing finishing. Disadvantage of low processing efficiency on the, hard alloy, titanium and other non-ferrous metal processing efficiency is very low. In order to wear small holes as the main processing aperture of 0.2mm-4.0mm, the use of hollow copper pipe with high efficiency, low precision, generally used as a wire cutting auxiliary machine. And cutting thread and wire cutting
wire cutting machine. As
the name suggests is based on the speed of the speed of the movement of the electrode. The use of molybdenum wire as the electrodewire loop.
