Covington has electrical discharge machines and supplies available. Electrical discharge machining, also known as EDM, is a manufacturing process whereby the required shape is created using sparks or eletrical discharges. Recurrent charpes removes material from a workpiece, while subjected to a voltage and separated by a dielectric liquid. By reducing the distance between the electrodes, one overcomes the dielectric capacitance, allowing current to flow. There are two basic types of EDM- sinker EDM and wire EDM. They're used in a number of technological applications in Covington, such as coinage die making, small hole drilling and metal disintegration machining. This process helps cut unconventional shapes in small, delicate pieces with great accuracy. Hard materials with close tolerances can also be cut. Its most common application is in mold-making tool and die industries, but now it is increasingly used in making airplane and electronic parts as well.
