The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. It was first discovered by an American, Joseph Henry. This procedure is a really efficient and precise method of cutting, drilling and inscribing metals. The primary benefit of using this technique is that it does not require heat or pressure to cut through materials.
There are numerous types of EDM makers which are readily available in the market. Manual EDM is mainly used for little tasks where there is no requirement for high precision.
Automatic EDM machines are generally utilized in large scale tasks where there is a requirement for high precision. One of the most crucial advantages of EDM over other machining processes is that it is less vulnerable to mistakes and can offer better accuracy.
EDM makers are generally based on 2 technologies, wire discharge machining and electrochemical machining. The former involves melting the metal and then removing it from the electrode through the action of electrical current. The latter usages chain reaction in between the electrode and the workpiece to remove the metal.
Wire EDM is one of the best approaches for carrying out the above mentioned jobs. The wire acts like a cutting tool and eliminates product from the workpiece. The speed of the wire determines the quality of the cut.
In the case of air, the workpiece is put inside a vacuum chamber and then the wire is fed into the chamber. The workpiece is put in the tank and the wire is inserted into the water.
In addition to these, there are numerous other aspects which identify the quality of the cut. Some of them are:
• The voltage applied to the electrode
• The kind of wire being used
• The type of workpiece being used
• The distance in between the wire and the workpiece
• The type of dielectric fluid being utilized
• The frequency of the electrical existing
• The kind of tool holder
• The temperature of the wire
The above mentioned elements affect the performance of the maker. Thus, in order to get excellent results, it is very important to understand the standard concepts of EDM.
