What is Wire EDM? |
Why choose Wire EDM? |
As explained by Engineering.com, "the EDM process is conceptually very simple: an electrical current passes between an electrode and a work piece which are separated by a dielectric liquid. The dielectric fluid acts as an electrical insulator unless enough voltage is applied to bring it to its ionization point, when it becomes an electrical conductor. The resulting spark discharge erodes the work piece to form a desired final shape."

Wire EDM cuts without making any contact to the part, therefore creating burr free surfaces. Because the wire is so fine, you can cut small-radius corners or even narrow slots. Since the wire never touches the work piece, there are no cutting forces, so you can cut thin stock, fine ribs, or even very delicate forms. Wire EDM is also an effective way of modifying materials after they have been heat treated. As a result, EDM has long been the answer for high accuracy and demanding machining applications where traditional metal removal is difficult or impossible.

Wire EDM means a different way of doing things. It requires a change in perspective—you have to think of wire and water instead of feeds and speeds—but it can make cuts not possible on a machining center.
