Similar to copper-tungsten in its manufacture, silver-tungsten is EDM small hole drilling requires the constant consumption of supplies. Silver-tungsten is a true specialist. Our company supplies electrodes, ceramic guides and electrode seals for a wide variety of small hole EDM drill machines. Single hole electrodes are usually cheaper in Both types allow for the flow of dielectric fluid, which aids in cooling and flushing. And though a brass or copper electrode is undeniably better for most softer applications, the rigidity of tungsten carbide gives it a specific use that no other material shares. Electrical discharge machining is favored over other machining methods because it makes drilling into very touch materials possible. left unaffected by the electrode, and no slug or piece of material is left at the bottom of the hole. Copper is second to silver in conductivity of elements at room temperature, which partly explains why it is so efficient at drilling. The internal channels are arranged in such a way that, as the electrode spins, no part of the workpiece is Holes have been drilled up to 500 times the diameter of the electrode. The type of flushing hole or the desired internal diameter of the electrode. machinable material, due to the softness of copper, and sheets of copper-tungsten are perfect for shaping sets silver-tungsten electrodes apart is conductivity. The Fine Hole machines utilize tube or multi-channel electrodes for machining of holes just like other EDM Drill machines. consistent and accurate EDM hole. Available as rods, single-hole, and offset single-channel tubes. Tungsten carbide electrodes are the toughest variety of EDM drill. robustness of a tungsten matrix solves this problem. Multi-channel tubes are used for drilling a blind hole. Brass and copper are in many ways very similar. Where even copper comes up short, tungsten carbide picks up the slack. So making sure that consumables are constantly in stock is vital to ensuring the smooth operation of a machine shop. Our tungsten carbide electrodes are made with 6% cobalt. hole drill. EDM Drilling Supplies Electrical discharge machining is precise, and there are many factors that influence the outcome of drilling.
