Electrical discharge machining (EDM), also known as electric discharge machining (EDM), continuously generates pulsed discharge sparks between the tool and the workpiece during the machining process. Its advantage is that it can process difficult-to-cut materials, very hard materials such as cemented carbide, and various High speed steel and even diamond and cubic boron nitride. Tungsten copper electrodes are widely used in the field of EDM due to their good physical and chemical properties.
Tungsten copper electrode is an alloy material with tungsten and copper as its main components. It has the characteristics of high strength, fast heat dissipation, good electrical conductivity, excellent thermal conductivity, excellent high temperature resistance and arc ablation resistance, and is widely used. In fields such as electric discharge machining, resistance welding, and electrochemical machining.
In EDM, tungsten copper electrodes can effectively improve processing efficiency, reduce electrode loss, improve the accuracy of molds and components, and can complete rough machining and finishing of products in one go. In addition, because the tungsten copper material has high strength and density, it can withstand greater mechanical pressure and heat, thus avoiding errors caused by electrode deformation.
In order to ensure the stability during EDM and improve the utilization of electrode materials, copper and tungsten materials are required to have high material uniformity and density. In addition, EDM electrodes need to provide copper tungsten electrodes with corresponding shape and dimensional accuracy according to the requirements of the tools, molds or products being processed.
In short, tungsten copper electrode material plays an important role in the EDM process. It is worth mentioning that although the manufacturing cost of tungsten copper electrode material is high, it can reduce the cost of the entire EDM process by improving processing efficiency, reducing electrode loss, and improving the accuracy of molds and components.
