Mitsubishi Electric EDM History
More than 30 years ago now MITSUBISHI ELECTRIC presented the first electro-erosive processing machine (EDM). Today, this know-how, acquired over many decades and combined with intensive research work, is still a decisive criterium when developing new EDM systems. Production also has an important status at Mitsubishi Electric. With a view to meeting the high technical demands, production is carried out in the most modern manufacturing plants under stringent quality controls.
The result is an extensive programme of beneficial and convincing EDM systems in terms of speed, precision and reliability.
