Precision EDM Services for Aerospace, Medical & Defense

An industry leader in precision wire, sinker and small hole electrical discharge machining (EDM), New Jersey Precision Technologies, Inc. uses top of the line Mitsubishi wire and sinker EDMs as well as CNC small hole drilling EDMs. Combining the highest quality fully-automated machines on the market and highly skilled machinists ensures we can accommodate your needs and meet all of your specifications. Our customers represent a variety of industries, with particular focus on medical devices and implants as well as aerospace, automotive and electronics. We can machine any conductive material, including hardened metals, superalloys, high-performance alloys, exotic metals and more, and we can handle projects of all sizes, whether they are prototypes, short- or long-run. Wire EDM can hold tolerances of ±.0001”, sinker EDM ±.0002”, and small hole EDM ±.0015”.

Why use EDM?

  • EDM can easily machine parts with very thin walls, complex geometry, narrow slots, small corner radii, very small features, etc. with virtually no mechanical stress.
  • EDM can cut hardened steel, titanium, Inconel and other difficult materials without the limitations of traditional machining.
  • EDM can achieve an excellent surface finish with no burrs right out of the machine.
  • EDM can reduce production costs with stacked parts machining using wire EDM as well as multi-up fixturing for wire, sinker and hole pop EDM.
  • Use EDM over broaching for better precision, accuracy and finish, no need to make a custom broach, and no risk of introducing unwanted debris into the finished part.
  • Use EDM instead of short-run stamping for straight-edge cuts with sharp corners and no shear or break as well as reduced costs by eliminating the need for special tooling.
