Simple System
Consistent flow of a pure, dielectric water enhances
the EDM machine's capacity to deliver a precise cut. That, in turn,
enables production of quality parts. Which is why you cannot underestimate
the value of your deionizing system.
It's especially
true for the latest EDM trend: high speed cutting. New EDM
systems call for flushing at
up to 300
psi, tripling and even quadrupling the load on pumps, filters
and resin.
EDM machine manufacturers are well aware of the
potential problems and have taken these considerations into account.
So operators should always observe the manufacturer's recommendations
for
setting up, using, and maintaining the deionized-water dielectric
system.

Extra Care
Better systems, as depicted in the schematic, are capable of automatically
monitoring water flow, temperature, pressure, conductivity, and
other factors affecting water purity. Operators should, as
well, pay special attention to the byproducts of machining, to
bacterial contamination, and to fungi contamination.
These
are frequent
culprits when the water system is not measuring up to the EDM production
demand.
As dissolved salts collect in the deionizer, of course, they
diminish the deionizing system's capacity to produce a dielectric
water.
That's when you should send the exhausted resin to ABA for replacement
at about half the cost of virgin resin.
There's another advantage to regenerating the resin with ABA.
Our regeneration process strips resin of contaminants which you
would
otherwise
need to
dispose
of according to federal
and state laws for environmental control. When we regenerate resin,
we also dispose of the contaminants according to regulatory agency
requirements.
