Wire Cut Edm Process

Extremely fine finishes of 12 rms can be produced with wire edm.

Wire cut edm process. Wire edm cutting advantages. As the wire is brought close the workpiece the electrical field increases as the distance squared. This fine finish is present even after very large parts are cut as in figure 5 2. Wire cut edm is a specific kind of edm process and is one of the most common.

Wire edm is commonly used on hard metals which are often difficult to machine. Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes separated by a dielectric liquid and subject. Wire edm produces an excellent finish even in the so called rough cut customers are often amazed when shown the fine finish of a single pass cut. Wire cut edm applications.

Because the process can cut very small pieces it is often an ideal choice for the production of small highly detailed items that would normally be too delicate for other machining options. Wire edm is also known as. This is wire edm electric discharge machining a process that can cut any electrically conductive material hard or soft even carbide or diamond. Wire edm cuts without contact burr free.

Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm. This history of wire edm is less clear cut than die sinker edm but what is known is that it was developed over roughly a decade between the 1960s and 1970s as a new method for making dies from hardened steel. Because the wire is so fine you can cut small radius inside corners or even narrow slots. Eventually the dielectric material will reach a point where electrical breakdown occurs and sparks will fly across the gap between the wire and the workpiece thus.

Wire edm machining is an electro thermal production process where a thin single strand metal wire in conjunction with de ionized water used to conduct electricity allows the wire to cut through metal by the use of heat from electrical sparks. Because of its versatility manufacturers use edm wire cutting machine operation for an extensive range of applications. For example for mass. Electrical discharge machining edm also known as spark machining spark eroding die sinking wire burning or wire erosion is a metal fabrication process whereby a desired shape is obtained by using electrical discharges sparks.

As the name implies wire edm uses a thin wire for an electrode.
