The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. The primary benefit of utilizing this method is that it does not need heat or pressure to cut through products.
There are lots of types of EDM machines which are available in the market. Manual EDM is generally utilized for small tasks where there is no requirement for high precision.
Automatic EDM machines are generally utilized in large scale jobs where there is a need for high accuracy. One of the most important advantages of EDM over other machining processes is that it is less susceptible to mistakes and can provide much better accuracy.
EDM makers are generally based upon two innovations, wire discharge machining and electrochemical machining. The previous includes melting the metal and then removing it from the electrode through the action of electrical existing. The latter uses chemical reaction in between the electrode and the workpiece to get rid of the metal.
Wire EDM is one of the finest approaches for performing the above discussed tasks. The wire acts like a cutting tool and eliminates product from the workpiece. The speed of the wire figures out the quality of the cut.
In the case of air, the workpiece is placed inside a vacuum chamber and then the wire is fed into the chamber. The workpiece is placed in the tank and the wire is placed into the water.
In addition to these, there are lots of other aspects which figure out the quality of the cut. A few of them are:
• The voltage applied to the electrode
• The type of wire being used
• The type of workpiece being utilized
• The distance in between the wire and the workpiece
• The kind of dielectric fluid being utilized
• The frequency of the electrical current
• The type of tool holder
• The temperature of the wire
The above discussed aspects impact the efficiency of the device. Thus, in order to get great outcomes, it is necessary to understand the standard concepts of EDM.
