Key advantage of wire cut EDM

The key advantage of Wire cut EDM is that parts may be cut after heat treatment which eliminates the possibility of distortion arising from post-machining treatments. Also, because the wire cut EDM method exerts no tooling pressure upon the workpiece, so the smaller and delicate parts are easily machined. Meanwhile fixturing requirements are minimal compared to conventional machining methods. More important, better surface roughness is possible to reach for wire cut EDM machining.
