Electric release machine (EDM) is a type of machining operation used to form a conductive workpiece into complex geometric parts. Electric release machines are ideal for machining components that have complicated contours or subtle cavities that will be difficult to produce with other conventional machining equipment. This process involves supplying electricity to the forming tool and workpiece and then carrying this tool closely with the workpiece, which is truly immersed in a dielectric liquid tub. This closeness causes the intensity of the electric field between the tools and workpieces to overcome the power of dielectric fluid, and resulted in a series of electrical disposal among them. This electricity release removes material from the workpiece, and the pattern or form of deleted material depends on the form of a tool electrode. After the machining operation, the dielectric liquid is replaced between the electrode. In addition to acting as a dielectric between two electrodes, the fluid also plays an important role in the machining process, because it is used to remove deleted material and cool the engine area. The process of processes in such a way that, while the material is removed from the workpiece; The tooling electrode is also gradually eroded, making periodic replacements needed.
The process of electrical discharge machining is very appropriate and is generally used in the production of components that are usually complex and require extreme accuracy. In addition, other application areas carried out by EDMS above par are in machining and forming wire edm parts for Agie Charmilles hard or exotic material such as titanium, hastelloy, covar, inconel, and hardened steel. However, the only warning with the electric debit machining process is that it can only be used with conductive materials.
Basically there are two types of electric release machines, which are different in the type of tooling electrode equipped with it. They are Edms and Wire EDMS sinkers. Edm Sinker, also known as RAM EDM using tooling electrodes shaped to facilitate the machining process. This tool electrode is formed by conventional machining into a form specifically for applications used for and the opposite of the right form to be included in the workpiece. The tools, usually machines from graphite, are used with fluid insulation such as oil or other dielectric liquids. This shaped tension is connected to the power supply and is made to approach the workpiece electrode, create electricity release between them, which causes erosion to the desired form. This type of EDM is usually used for machining the right 3D complex parts, such as injection mold, die tooling, and other components that require extraordinary accuracy.
EDM wire, on the other hand, is an electric release machine that uses fine metal wire, usually made of brass, which acts as a cutting electrode to accurately form complex and complex components of thick metal plates. The wire and workpiece are both included with electricity and when the wire approaches the workpiece, electricity releases occur between them. This release removes materials from workpieces in a form similar to cutting or slicing actions. When the wire electrode is handying together with a workpiece, it continues to be inserted into the workpiece of the spool to ensure an unbroken cutting operation. Wire is inserted through two guides, usually made of diamonds, each placed above and under the electrode of the workpiece. This guide can be moved on an X-Y 2 axis plane and CNC controlled to cut. Cutting operations occur in workpieces that are truly immersed in dielectric fluid baths, usually ionized water, which are used as coolers and to remove deleted materials. This machining process is used to cut 2D forms that are complicated and complicated in thick metal parts, especially CO
