Karmel Onandia, founding partner and chairman of ONA, is another figure whose life has been intimately involved in the development and expansion of EDM. Founded in 1952, it was in late 1954 that ONA achieved a patent for the development of the initial technology, which was still in the experimental stage. One year later the first ONA electrical discharge machines were on the market. Since then, ONA has continued to be firmly committed to EDM. ONA is headquartered in the Basque region of Spain, where all their Die Sinker and Wire EDM equipment is manufactured. Today, ONA is the oldest EDM firm in the world, and the leading manufacturer in the European Union.
