When intricacy and accuracy are critical to your part, our CNC EDM facilities are the answer.

EDM, or Electrical Discharge Machining works differently than conventional machining. The EDM process works by generating a spark between in an electrode and part to be machined. This spark produces enough heat to erode the part surface. In fact, with temperatures reaching as high as 12000 degrees Celcius, the EDM process is ideal for hardest to erode metals. Dielectric fluid water is applied throughout the process to carry the current between the electrode and the work piece. The fluid also helps to cool the electrode and carry away debris generated by the process.

With 4 EDM wire machines, 2 EDM sinker machines and 1 EDM hole-burning machine, we offer our customers complete CNC capacity with unlimited geometry.

• Wire EDM: Similar to an ultra precision bandsaw in operation, a machine fed spool of wire acts as an electrode in this EDM process for extreme precision and tight tolerances (as low as .0002").
• EDM die-sinking: EDM die sinking allows us to erode a predefined shape of practically any geometry into your part.
• EDM hole-burning/drilling: This process works much like a drill and drillbit, but works where drills cannot due to the hardness of the work piece and degree of precision required. By spinning a hollow electrode of various sizes into the work piece, holes as small as .012" can be produced in even the hardest of metals.

Both Wire EDM and Sinker EDM have the capability of machining fully hardened tool steel or any other conductive material to nearly any geometric shape and with the precision required for nearly any application.
