Today the trend of micro products is very much inn in the market and to Wholesale Extruder Screws Barrels Manufacturers develop such products it is necessary to design such parts which are small, short, concise and complex so that various tasks can be performed by one part. When such a work piece is to be designed in which is very complex and unreachable for normal cutting machines then EDM wire method is used as it can reach in those places very easily. BasicallyEDM wire is a cutting procedure which is used to make complex work pieces.

EDM stands for Electrical Discharge Machining and in this process cutting is done with the help of electrodes and liquid de-ionized water. This machining is used so that geometry can be maintained in work pieces. The most important benefit of this machining is that it does not harm the work piece at all infect it doesn’t even touch the work piece, that’s how geometry is maintained with in work pieces.EDM wire is a method which involves a wire and this thread of wire is usually of brass. This wire also plays an important role in many manufacturing industries as it helps in cutting and designing a lot. This machine consists of following components.

First component of this machine is a set of electrodes, second is dielectric liquid and third is brass wire. One of the electrodes is called as work piece electrode and the second electrode is known as tool electrode. these electrodes are kept away from each other when cutting is not to be done, and when cutting has to be done then these electrodes are moved in such a way that their distance reduces. When the space between two electrodes is minimized then the intensity of electric field starts becoming powerful, through this process excess material is removed from the work piece or steel plate. There are two types of basic EDM methods one is ram EDM and the other one is EDM wire or wire EDM. The difference between these methods is very minute and it is the difference of electrodes.

The electrodes used in EDM wire are normal one but the electrodes of ram EDM are made of especial material. These electrodes are made of graphite and are used for specific purposes.The dielectric fluid used in EDM process is also have its own importance and performs a number of tasks in this procedure. After the cutting and finishing of work piece this complete this fluid washes away all the debris of the work piece and exposes all the cuts and designs of the product. This fluid also reduces the heating effect of the electrodes and work as a coolent as well. Due to this the work piece did not get any damage during the process. As this fluid is of dielectric nature that’s why it acts as conductor and allows current to run between the electrodes and work piece. Usually the process of EDM wire machining is conducted in a tub of water
