Drilling EDM machines use high-pressure dielectric fluid (typically deionized water) through the tube to enable cutting operations and flush away any eroded debris. The dielectric oil in a Sinker EDM serves a number of functions: • The dielectric oil acts as a medium through which controlled electrical discharges occur. Hole Drilling (or Popping) EDM uses a small (Ø .006 - .050”) tube electrode to drill holes in hardened materials. Note also the relatively stable viscosity of the Dielectric fluid as temperatures range from 0 to 100 degrees Celsius. Yes, You can answer kerosene oil as dielectric in EDM process. Get a waste oil furnace. He say's even the tiniest amount of oil residue mixing with the dielectric fluid would make it iffy to use on modern EDM's. Sinker EDM, also called ram EDM, cavity type EDM or volume EDM, consists of an electrode and workpiece submerged in an insulating liquid such as, more typically, oil or, less frequently, other dielectric fluids. The desirability of suppressing electrical discharge in electrical discharge machining might seem counterintuitive, but suppression allows for controlled discharge, and enhances the quality of machining. Fluid A. List three of the main functions of the dielectric fluid used in the electrical discharge process. In die-sinking EDM, kerosene is often used as a dielectric fluid because it provides lower tool wear, higher accuracy, and better surface quality. © 2019 Holepop EDM Supplies & Electrodes LLC. easily available.
