Deionized water is very corrosive; the deionizing system components should be matched according to materials of design as well as performance.

Deionization assures high quality water for high quality parts.

High-Speed Systems

Consistent flow of a pure, dielectric water enhances the EDM machine's capacity to deliver a precise cut. That's
especially true for high speed cutting. These EDM systems call for flushing at up to 300 psi, tripling and even quadrupling the load on pumps, filters and resin.

Better systems, as depicted in the schematic, are capable of automatically monitoring water flow, temperature, pressure, conductivity, and other factors affecting water purity.


Extra Care in Filtering

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 regeneration.

Operators should pay special attention to the byproducts of machining exotic materials. Same for fungi contamination and bacterial contamination, which are frequent culprits for water problems.

Machine manufacturers are well aware of the problems, and have responded with clear guidelines for setting up, using, and maintaining their systems.

For Perfect Parts

A good EDM water makes machining precision parts possible.
Fine-tuned EDM systems are capable of routinely producing high quality, precision-manufactured parts.
