The Electrical Discharge Machining (EDM) is a concept wherein an electrode zaps a work piece eroding it gradually using the electrolyte to flush away the debris progressively. This is a highly accurate way of machining that is affordable, as well. The EDM hole popper is a variant of EDM technique in which rows of holes are drilled very accurately into the leading and trailing edges of turbine blades in a jet engine.
The small hole EDM drill is also used to create microscopic orifices for fuel system components and spinnerets for synthetic fibers such as rayon besides other applications. The professional precision engineering companies in the US have three Charmilles wire EDM machines besides one EDM current drilling machine.
The EDM hole popper is one in which a brass or copper electrode is used that is between 0.004” and 0.250 inch in diameter. It is this electrode that blasts holes through the work piece. The EDM drill cuts by the rapid pulsing of sparks that emanate from the electrode and strike the work piece. Each time the spark strikes, it erodes the work piece and the electrolyte flushes the waste material away. After a number of cycles, a hole is created without the electrode ever having to come into contact with the work piece. There are some poppers that can punch holes in a large variety of sizes. EDM drills are available in different strengths. Precision engineering companies have a large range of drills for best results. These drills are available in several brands to select from.
