Electric Discharge Machining & EDM Companies
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.
Rather than using abrasion or impact, EDM machining erodes the material in the path of the EDM tool using electrical discharges, or sparks created by the electrode which is connected to a power source. The tool electrode forms an arc to the work piece as the two are brought closer together, creating an intense electric field between the two components which is responsible for removing material. EDM is often referred to as spark machining, spark eroding and die sinking. For extreme precision parts, micro EDM is used as it can achieve tooling and machining on very small scales. Wire EDM (or wire erosion) and sinker EDM, also know as plunge EDM, conventional EDM or ram EDM, are the two main types of EDM machining differing in their method of achieving the electrical discharge required. Sinker EDM uses an electrode whereas wire EDM uses a wire, typically made of brass, to transmit sparks to the work piece. Sinker, or plunge EDM is capable of boring holes into metal work pieces, creating holes, patterns and at times three dimensional objects, while wire EDM cuts patterns and shapes. Both are effective methods and are widely used. Small hole EDM is a type of EDM drilling which is also required as a pretreatment for wire EDM in order for the wire to be fed through a part.
