OUR PRODUCTS, TECHNOLOGY AND BRIEF HISTORY
Our AA EDM patented and proprietary technology is the outgrowth of developing, manufacturing and supplying over one thousand micro hole EDM machines since the 1970's.  We are consistently updating our technology, designs and execution while we are working closely with our customers to understand their needs, solve problems, customize and streamline their process, so they in-turn can be productive and competitive.  We are a small and extremely innovative company focusing on our area of expertise, but at the same time, we do have the flexibility and the know-how to design and execute to meet your needs so that you can produce the best solutions for your own customers - just let us know what you need and we will make it happen.

Our company's core talent goes back to Raycon Corporation in the 1970’s where we developed machines that sold around the world. At Raycon we made the world’s first computer controlled EDM generator – the CP60. We developed and patented the use of flow testing to control EDM hole size in injectors. We started the EDM division of Ann Arbor Machine Company in 1992 and continued our innovation by improving cycle times and hole quality, a patent pending reverse taper (K-Factor) EDM head and adding ease of use features, vision systems and laser markers to our machines. Ann Arbor Machine Company was purchased in a leveraged buyout in 2005 and as a result had too much debt to withstand the auto industry meltdown and went into receivership. The losses incurred by the automotive related machine tool division of AAM were too high even though the EDM division had a very profitable year. So the founders who had been together at Raycon and AAM bought the assets of AAM Company and formed AA EDM Corporation to continue doing what they do best – make Microhole and Aerospace production EDM machines.

​In 2016 AAEDM and ONA formed a partnership.  ONA, a renowned EDM European company includes now in their product lines the experience and innovations of our AA EDM manufacturing EDM microhole drilling machines. ONA has a worldwide presence thanks to its international network of subsidiaries and distributors whose purpose is to advise and assist customers in choosing the solutions that best suit their needs.  AA EDM is proud to be affiliated with ONA that has more than 60 years of EDM know-how and experience and 14,000 machines installed worldwide.
AA EDM  COMPETITIVE ADVANTAGES​
  • Fastest cycle times while capable of producing the highest quality holes. Our sensing circuitry and the high speed pulse control maintain an optimum speed/quality relationship to deliver consistence performance over many years with maintenance free operation.
  • The EDM heads (there are several to choose from) use a brushless DC motor and DSP microprocessors to control the electrode precisely in a super-hard, super-precise wire guide.
  • Our standard straight hole has been in production for years, our K-Factor (reverse taper) patent pending head is fully programmable from straight holes to K-Factor of 5.5.
  • We make dual and triple wire guide heads that will make parts with multiple hole sizes or can be used to quickly change from one part to another as the proper guides and electrodes are already loaded on the machine for maximum operation efficiency and ease of use.
  • One of our unique features can increase or decrease flow with just a press of a button without even changing the electrode.
  • Our wire guides cover a wide range of electrode diameters – so you don’t need to stock lots of sizes. Five wire guide sizes cover a range of electrodes from 75 microns up to 400 microns (0.003” to 0.015”). Our guides cost $525 and last 500,000 holes – the competition charges almost 4 times that and they only make one fourth the holes! Our electrodes are available from several sources and cost less than $2.00 each. Compare that to proprietary electrodes that cost $28.00 each that our competitors require.
  • Our machines are mechanically robust and reliable --- they are easy to service and maintain due to the many innovations incorporated in their design. Our customers report to us that they achieve a 96% uptime using our equipment (the highest uptime of any machines in their factories).   More
  • The cost to run and maintain AA EDM microhole EDM machines is significantly lower than that of other suppliers. Our uptime is far superior and consumables such as electrodes and wire guides last longer and cost less.
  • Simpler maintenance and more flexibility in setting up the machines for different parts all contribute to saving the customers’ money.
  • Our machines do not require dedicated maintenance personnel either.​
