An EDM is well-suited to machining harder materials that aren't as receptive to traditional machining methods, such as titanium. It's also better at creating complex shapes than traditional machining methods. This is because the machine relies on electricity instead of a tool that has to navigate corners or complex edges. In addition, because the machine requires no direct contact with the workpiece and vaporizes the removed material, the amount of cleaning required after the machining process is greatly reduced.
