The new EDM machine might be running only one-third of the time, Bond said, and then someone realizes it could run overnight for $25 or $50 and get a part made. Since the hardness of the material being cut has no effect on the cutting speed, Wire EDM can be used to cut a wide range of conductive materials including hard metals or materials that are fairly brittle and would be damaged by other machining processes. Wire EDM services are perfect for projects that require the materials to be cut straight through or tapered. Its use is limited to electrically conductive materials. 42 0 obj /Length 767 endobj EDM electrode materials need to have properties that easily allow charge and yet resist the erosion that the EDM process encourages and stimulates in the metals it machines.
