Following on the experience and success with its die-
lectrics in the field of electrical discharge machining
(EDM), oelheld has now set itself new targets. Whereas
high-quality hydrocarbons have been successfully used
for decades in cavity-sinking EDM, water is still used in
wire EDM - and that despite the numerous associated
disadvantages.
Particularly when machining carbide metal, cobalt lea-
ching and hence also corrosion present a problem that
is difficult to overcome. That is why oelheld together
with leading companies in the EDM field and the Uni-
versity of Louvain (Belgium) decided to set up a research
project to develop a hydrocarbon-based dielectric that
is designed specifically for the wire EDM technology.
The result is lonoFil.
