The EDMs are equipped with a reusable Molybdenum wire feature, which quickly moves inexpensive wire from the source capstan, to the receiving capstan, and then back again so that the wire is continuously moving back and forth through the workpiece. The rapid speed of the wire (till 50 times faster than a normal wire cutting machine) creates its own flushing so high-pressure pumps are not required. The Molybdenum wire is very resistant to wire breaks, offering an advantage over the brass wire that is typically used in a wire EDM. The dielectric is a mixture of water and oil to reduce oxidation on the part surfaces.
