Since 1971 Kleinknecht has supplied single-channel generator systems for Ingersoll EDM machines—this was extended up to 60 channels for EDT machines.

The first generation of these generators was water-cooled. As of 1996 the second generation of generators was launched as air-cooled units.

Our latest generation is based on state-of-the-art SMD technology, in a much smaller and more compact size.
