Deionization assures high quality water for high quality parts.
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
Fine-tuned EDM systems are capable of
routinely producing high quality, precision-manufactured parts.
