Wire EDM Company Serving Milwaukee, WI

Need small batches or short runs of highly accurate, tight tolerance components from a wire EDM cutting shop?

Trusted Worldwide Since 1963

Natura Products, a wire EDM contract manufacturer with deep roots in cutting die manufacturing, is based in Northbrook, Illinois, USA and serves customers in Milwaukee, WI. We have 60 years of proven experience and are trusted by some of the most recognizable companies in the world for wire EDM services. We excel at wire EDM machining and production of high-quality, high-precision parts in the automotive, petroleum, medical, pharmaceutical, electronics, nuclear and aerospace industries.

Wire EDM (Electrical Discharge Machining) — sometimes called "cheese-cutter" EDM, arc machining, die sinking or spark machining — can machine extremely hard materials such as monel, inconel, titanium, kovar and hastelloy to very tight tolerances. It can also machine steel, brass, and other metals. Wire EDM can handle complex, detailed and intricate patterns unsuitable for traditional machining methods.

Wire EDM can:

  • Machine hardened or heat treated material, eliminating risk of distortion from secondary treatments
  • Handle complex shapes, narrow slots, and fine holes that are difficult using conventional cutting tools
  • Output very fine surfaces
  • Machine sharp, square-edged internal cuts
  • Produce small quantities including prototypes
  • Create accurate prototypes with shorter lead times
  • Produce very small pieces
  • Cut extremely hard material to very close tolerances
  • Cut intricate contours and cavities in pre-hardened steel without the need for heat treatment
  • Machine fragile sections and weak materials without distortion
  • Output accurate, predictable, repeatable results during every production run

How Wire EDM Works

Wire EDM uses precisely controlled electrical discharges — sparks — created between an electrode and a workpiece. These sparks produce intense heat and melt a small path along the workpiece. The spark is very carefully controlled and localized. A wire acts as the electrode and slowly passes through dielectric fluid before and after passing through the workpiece. Dielectric fluid acts as an insulator, flushes eroded scrap particles, and cools the workpiece. The wire passes through the workpiece similar to how a woodworker's band saw passes through wood. Unlike a band saw, there is no direct contact between the wire and the workpiece. The spark occurs between the workpiece and the wire, allowing for machining without distortion of the workpiece.

60 Years of Quality

Natura Products is certified by UL DQS Inc. to the International Organization for Standardization ISO 9001:2015. We are an affiliate of Chicago Cutting Die and a global supplier of high-performance matched dies, stamping, and wire EDM. Natura was established in 1963 by a former Chicago Cutting Die employee, Dick Brettner. Dick named his new company after his first customer: the Field Museum of Natural History.

Dick was a talented die maker and a trusted outsource partner of Chicago Cutting Die for decades. When Dick retired in 1985, Chicago Cutting Die's holding company acquired Natura Products. In 1995, both companies moved to Northbrook, Illinois. The companies now share a facility and a commitment to precision, quality, and personal service.
