For The Professionals in EDM

Electrical discharge machining or EDM is perhaps the most accurate among the manufacturing processes that are available for the creation of complex shapes and geometries within assemblies or parts. EDM manufacturing involves the erosion of material in the line of electrical discharges formed in an arc between the work piece and an electrode tool. This is an affordable and very desirable process of manufacturing wherever you require high accuracy or low counts. The EDM hole popper or the EDM drill is one of the options of using the EDM technique.
Modern technology demands several characteristics. drill edmOne such characteristic is the level of accuracy required in engineering products. The second characteristic is the volume of production necessary with this level of accuracy and tight tolerances. Yet another requisite is the need at times to make holes in very high temperature alloys. It is not possible to drill such holes using conventional machines. There are some ISO qualified precision products manufacturers that have all these qualities. They have CNC high-speed hard milling machines besides CNC milling, multi tasking machines and CNC lathes. Besides these resources, these quality manufacturers of precision products also have capabilities in terms of metallurgical analysis and EDM machining and current drilling. These companies service several kinds of industries that include textiles and power generation, medical and defense, automotive and firearms besides plastic, rubber extrusion, jet turbine fuel systems and aerospace among many others.
The EDM hole popper is also used for the creation of microscopic orifices for components in the fuel system, spinnerets for synthetic fibers such as rayon and others. There are also small hole drilling EDM machines that are known as super drills. These can machine blind or through other holes. The EDM drill bores holes with a long copper or brass tube electrode that rotates in the grip of a chuck with deionized water serving as a dielectric and flushing agent.
There are small hole drilling EDM machines, used to serve the role of the EDM hole popper or the EDM drill. These machines are used in several applications. One of the most important of these is the aerospace industry where this EDM is used for the purpose of drilling several rows of holes in both the leading as well as the trailing edges of turbine blades that are used in jet engines. These holes serve to enable the engines to use far higher temperatures than would have been possible otherwise. Since the blades are very hard EDM machining is the only viable alternative.
