What can Wire EDM do?

If you have no idea how a Wire EDM Machine works, than take a few minutes to read the two article's located in the left toolbar. They get into some specifics of the machine functions, and the EDM process itself. You may find it helpful.

Wire EDM uses a Brass wire and an electric current to cut a slot straight thru metal parts. It can cut in from the side of a part, or you can use a start hole to cut internal features. In most cases, the material is removed without adding mechanical stress's to the finished part. It allows you to cut very small slots, or you can remove a large mass of just about any shape. It is possible to taper cut a cavity using a specific angle on each side, or you can cut a 4-Axis program that would taper from one shape to another (i.e. circle on top to a square on the bottom) These can be used in many applications such as food processing, and plastic extrusions. Wire EDM can cut almost any electrically conductive material. If you compare Wire EDM to milling or turning it seems extremely slow, however it is very cost effective on many types of parts.
