The perfect EDM electrode is dimensionally perfect. EDM electrodes are most commonly found in tubular form. With 18 locations across the US and Canada, Electrodes Inc. has been the industry leader for over 50 years. One unique characteristic of copper is its ability to drill through very hard materials such as carbide and A Drill for Every Job. In electrical discharge machining, rods are a rarity. hole drill. price because there is less material in the electrode. EDM Electrodes Electrical discharge machining (EDM) is a machining method favored by industries such as aerospace, energy, and biomedical engineering for its flexibility and accuracy. Brass and copper are in many ways very similar. The Fine Hole machines utilize tube or multi-channel electrodes for machining of holes just like other EDM Drill machines. Our brass alloy composition is 65% copper and 35% zinc (alpha brass). With 18 locations across the US and Canada, Electrodes Inc. has been the industry leader for over 50 years. electrodes are manufactured by infiltrating a tungsten matrix with molten copper, and the resulting material Available as rods, single-hole, and multi-channel tubes. Holepop EDM Supplies and Electrodes is a provider of high precision, customizable components used in electrical discharge machining small hole drilling. The internal channels are designed to burn away any Brass is fast at the expense of wear rates. Brass electrodes can be used at a faster machining rate but wear out quicker than copper electrodes. Complete EDM application solutions by Belmont Equipment & Technologies: Astec EDM Drills, SY EDM Drills, Maxicut EDM Drills, Maxicut EDM Sinkers to meet all your EDM needs! Create very small holes, including pilot holes to run EDM wire through. tungsten carbide. Our tungsten carbide electrodes are made with 6% cobalt. GT-1 & EDM Drill Plus Additives for EDM Drilling; Ceramic Guides; Tooling Packages; Filtration Systems; MACHINERY Maxicut Sinker EDM. Brass EDM tubing and copper EDM tubing can both be single hole. PREV. EDM Small hole drilling, and one electrode’s weakness in one application may be a strength in another. Brass EDM Electrodes Brass electrodes are the bread and butter of electrical discharge machining small hole drilling. And just as sparking erodes a workpiece, it erodes the electrode itself. Electrical discharge machining, with its lack of tool pressure, can drill into materials from hardened steel to tungsten carbide, and is a favored machining method in the nuclear energy, defense, and aerospace industries. the brass electrode or copper electrode tube is has a single hole or multiple channels running directly through the The brass we use is 99.995% pure and is comprised of approximately 70% copper and 30% zinc. Copper tubing can be used for small hole drilling in all material types. machinable material, due to the softness of copper, and sheets of copper-tungsten are perfect for shaping For blind-hole drilling, where the drill does not exit the workpiece, a single-hole tube will leave a chunk of slag where the tube’s cavity was. Check out our customizable conventional ceramic and silicon nitride guides below, compatible with Current EDM and Agie-Charmilles machines. ID or (Internal Diameter) of the electrode. So making sure that consumables are constantly in stock is vital to ensuring the smooth operation of a machine shop. Blind holes are not drilled all the way through a workpiece, This is very The power usage and electrode feed rate, as well as the motion of the machine's axes, are all controlled by the machine's CNC. An overheated electrode can warp and bend, impinging on its ability to drill accurately. Novidrill spark erosion drilling machines Affordable quality EDM drilling Machine Our EDM Rapid hole drilling machine uses low cost electrode tube (normally brass or copper material) to drill holes on a electrically conductive material at a very high speed, the hole depth diameter ratio can reach up to 300.
