Large EDM Capacity

Large EDM Capacity

View Our EDM Glossary Here

Wire EDM of parts up to 10,000 lbs.
Adron was the first wire EDM job shop to apply wire electrical discharge machining to ultra-large work pieces, which can weigh up to 10,000 lbs. We were the first US shop to utilize the largest EDM machine available, the Mitsubishi 400H1. Our contouring capacity is 32 in. x 40 in. x 18 in. thick.

Heavyweight Parts

A 10,000-lb. part has become a typical Adron job. We have had 9,600-lb. molds on our largest Mitsubishi machine, which we modified for cutting big molds and parts. This 8,700-pound, 40 in. x 46 in. x 16 in. thick block is typical of the large core and cavity work Adron performs for the plastic injection mold industry. Our wire EDM reduced the number of operations from six to two and did not destroy the core, which in this case weighs 2,300 lbs. This mold is for a residential recycling bin.

Large cutting dimensions

The large cutting dimensions of the Mitsubishi 400 made it ideal for a 2-1/2 lbs., 28 in. diameter part for NASA’s Genesis Mission. We were able to complete the job in one set-up, assuring accuracy.

Precise alignment of curved 36 in. lengths

For metal sculptor Merlin Rostad, wire EDM achieved the precise alignment he desired. Forty-nine curved lengths were cut from a single block of aircraft grade aluminum measuring 13-1/2 in. x 13-1/2 in. x 36 inches tall.

Thin ribs

We have cut a number of 22-in. thick parts with thin ribs for wind tunnel balances, on the machine, contained, and holding tolerances. For the NASA wind tunnel component shown here, we cut precision strain gage ribs through 22-inch stainless steel.

Capacity = Ability to wire EDM large work pieces

Capacity = Fast throughput of jobs requiring lots of cutting

Whichever way you define capacity; Adron delivers it!


  • Fast Turnaround
    Our large capacity means that we have wire EDM machines in size and quantity suited to your job.
  • Rapid Prototyping
    Wire EDM reduces or eliminates fixture and tooling costs. Parts can be immediately in production.
  • Wire EDM of Exotic Metals
    Wire EDM has an exceptional capability to machine exotic materials (A-286, Hastelloy, niobium, tungsten, aluminum alloys, copper, etc.)
  • Elimination of Heat-Treat Distortion
    Because hardened materials can be wire cut, EDM eliminates the need for post-machining heat treating and possible part distortion.
  • Burr-free, Superior Edge Quality Applications
    Most workpieces come off the EDM machine as accurate, finished parts, burr-free and with excellent surface finishes. Simple, flat shapes, which usually would be stamped, may be a job for wire EDM when they require a superior quality edge.
  • Intricate Contour
    Wire EDM can produce complex, contoured shapes, freeing you to design the configuration you want, in one piece rather than several.
  • Tight Tolerances
    Wire EDM is one of the most accurate machining processes for making contoured parts.
  • Absolute Consistency
    Because there is no tooling to wear, wire EDM offers absolute consistency, part after part.


Adron Tool Corporation was among the first to recognize and utilize wire EDM as a true production process. During more than 20 years of specializing in wire EDM, we have completed thousands of production jobs for almost every industry. We have 50 high-speed wire EDM machines in all sizes; including the largest wire EDM machine available, able to handle work pieces weighing up to 10,000 lbs.
