Metal machining is a common term. Almost everyone knows about it. It’s simple and a cost efficient way to cut simple shapes out of metal. However, very close tolerances are hard to achieve unless the  machine is absolutely state of the art.

Wire EDM or wire electrical discharge machining is something that can cut metal extremely precisely into very complex shapes and achieve tolerances that are in the order of a few microns – about 100 times thinner than your.
