ONA also makes its way into Europe with micro-hole electrical discharge machining technology

The advantages of these machines are numerous and important: Including a high degree of accuracy in finishes, savings in machining time of up to 30%, and a much more economical maintenance

ONA also makes its way into Europe with micro-hole electrical discharge machining technology

 

The American company AA EDM Corporation, of which ONA owns 30%, sells the first micro-hole appliances on the continent to an important Italian manufacturer of automation injectors

The advantages of these machines are numerous and important: Including a high degree of accuracy in finishes, savings in machining time of up to 30%, and a much more economical maintenance

 

ONA is the world's most long-standing manufacturer of electrical discharge machining equipment. We are leaders in the manufacture of large equipment, as well as experts in providing special solutions. We have been involved in the development of technologies related to this machining technique for more than 65 years. In addition to the headquarters in Durango (Vizcaya) –an 11,000 m2 plant for the manufacture of equipment, and other 1,500 m2 entirely destined to R&D–, we have 5 affiliates in Europe, America and Asia, as well as a wide network of highly qualified distributors to offer optimum service to companies.

 

We have always been careful about our expansion policy, thinking each decision thoroughly and seeking to establish, whenever possible, solid cooperative relationships with other companies in the sector that would allow us to continue growing and improving, without adding rigidity to the structure, but quite the opposite: Flexibility to be able to respond efficiently to different situations. We have never sought to create an extensive network of affiliates, but rather to adapt to each need according to circumstances.

 

With these parameters, we acquired 30% of the North American company AA EDM Corporation, a Michigan-based company specializing in the design and manufacture of highly accurate micro-hole electrical discharge machining equipment. This agreement enabled ONA to enter fully into the technology of micro-hole electrical discharge machiningand its usage in sectors such as energy, aerospace and automation, in which we already had an important presence with die sink and wire electrical discharge machining equipment.

 

On the other hand, AA EDM could use ONA's know-how for the manufacture and improvement of its equipment, in addition to our experience and deep knowledge of the European market, its pending assignment. The company has focused almost its entire activity in the United States, with significant operations in Russia, China, India, and South Korea.

 

Europe was its great challenge, and, thanks to ONA, it is facing it: A recent agreement has been reached for the sale of micro-hole electrical discharge machining equipment with an important company in Italy; precisely, one of the countries to which ONA sells the most, along with Portugal.

 

AA EDM model with a high-degree accuracy

The Italian company specializes in the manufacture of injectors for the automation sector, with a range of more than 2,000 different products applicable to different engine types. It already had other 4-shaft micro-hole electrical discharge machining equipment, and has now acquired its first triple head AA EDM model in order to obtain a highly accurate finish. This equipment's 'relevant' advantages, in comparison to the competitors', made it 'a lot' easier for the Italian company to decide to buy. 

 

Some of those advantages are:  

1)     AA EDM machines do not use heads or rotating electrodes. This eliminates an important source of errors. These heads can last for decades. There are no deviation problems either. Wide range of hole shapes: Conical, semi conical and irregular. 

o   The electrode guides of AA EDM machines are designed by taking into account the importance of flexibility. We provide 2-piece electrode guides that allow the use of a wide range of diameters.

o   Approximate price: €490.

o   More than 500,000 holes per electrode guide.

o   Change time: Less than 5 minutes.

o   6 different sizes: Cover the full range of hole diameters.

2)     High-range YASKAWA servomotors in X, Y, Z with direct activation on the C shaft. We have been producing machines for many years, and we have never had to replace a motor because of a failure. On the B shaft tilt, we use a Harmonic unit with a 50:1 reduction for exceptional accuracy.

3)     Highly automated equipment. Capable of totally working in an autonomous way, increasing profitability and productivity. Machines have the Beckhoff CNC control system made in Germany by default, which is very simple to use.

4)     400% cheaper electrodes for the same rod length. Each electrode makes at least 2,400 holes.

5)     AA EDM generator technology is faster. In addition, the machine electrodes don't need to be changed so often. The result is savings of up to 30% in machining time.
