Wire Cut Edm Process

Wire edm is commonly used on hard metals which are often difficult to machine.

Wire cut edm process.

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. With the wire edm cutting process controlled and rapidly repeating electrical charges are used to remove material from electrically conductive materials. Because of its versatility manufacturers use edm wire cutting machine operation for an extensive range of applications. 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.

As the wire is brought close the workpiece the electrical field increases as the distance squared. Wire edm is also known as. 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. This is wire edm electric discharge machining a process that can cut any electrically conductive material hard or soft even carbide or diamond.

Wire electrical discharge machining wedm uses a metallic wire to cut or shape a workpiece often a conductive material with a thin electrode wire that follows a precisely programmed path. Extremely fine finishes of 12 rms can be produced with wire edm. 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. As the name implies wire edm uses a thin wire for an electrode.

Because the wire is so fine you can cut small radius inside corners or even narrow slots. It is a very precise method for the right applications such as for 2 axis cutting of small parts with tight tolerances at high volumes. Wire edm cuts without contact burr free. 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 cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm. Wire cut edm applications. For example for mass. 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.

This fine finish is present even after very large parts are cut as in figure 5 2.
