Below is a list of EDM manufacturers from Lincoln, Nebraska. EDM, an abbreviation of electrical discharge machining, is a specialized tooling method that uses electrical energy to cut, drill, etch and machine metal parts. Electrical discharge machining is one of the most accurate types of machining processes as it is able to achieve complex geometries and details especially when using CNC EDM machines to control the process. EDM cutting and drilling is also suitable to be used for both hard materials and extremely delicate materials which are difficult to machine with conventional cutting methods.
