Sinker EDM – Sparks of Genius
Sinker EDM uses an electrically charged electrode that is configured to a specific geometry to burn the geometry of the electrode into a metal component made from either Copper, Graphite or Tungsten. Within a dielectric bath such as oil or deionized water, a spark is created between the electrode and workpiece to burn the geometry of the electrode into metal workpieces. Also known as conventional EDM, plunge EDM or Die-Sink, this process is ideal for sharp corners, internal keyways, splines, hexes or cavities. At Apollo, we offer the most precise and accurate sinker EDM using 13 sinker-style machines with 30″ × 20″ extended tanks, with an attainable tolerance of 0.0001″.
Wire EDM – Doing What Others Cannot
Also known as Wire burning or cutting, Wire Electrical Discharge Machining uses a thin wire electrode (0.005″–0.010″ in diameter) made from brass or copper to cut conductive material along a pre-programmed path. There is no contact between the wire electrode and the workpiece. Instead, like the sinker EDM process, the spark discharge erodes the material. Wire EDM is ideal for machining complex parts and precision components out of hard, conductive materials such as titanium, inconel and carbide. Apollo is equipped with three wire-style machines with 47″ × 27″ tables and a 15.75″ maximum height. Four axes allow for tapered cuts. We take pride in our ability to take on any job regardless of the complexity. Through our state-of-the-art EDM department, we manufacture parts that would not be possible with conventional machining.
