Ion Exchange Resins

Ion exchange Resin is made from strong acid cation exchange resin and strong base anion exchange resin. Removes metal oxide (Fe +, Cu +) from deionized water. Deionized water serves as the dielectric in a Wire EDM. Prior to the discharge, the deionized water acts as an insulator. Due to this, an electrical potential is developed between wire and the work piece. Once the electrical potential between the wire and the work piece builds to a certain intensity, the dielectric breaks down and forms an electrically conductive path (known in EDM as the Discharge Channel). This conductive path allows the energy of the spark to be transferred from the wire to the work piece for metal removal.
