When wire EDMing carbide, the cobalt will start to break down due to oxidation caused by the dielectric fluid even while EDMing is not taking place. In order to further reduce oxidation of the carbide tool, Seibu’s EL Coating applies a very thin layer of brass wire onto the carbide during the final trim pass. This thin layer of brass protects the carbide’s cobalt from the oxygen ions located in the dielectric fluid. If the cobalt is not protected after the final EDM skim pass, it is attacked by the oxygen ions. Carbide is a hard material used to produce stamping and drawing dies. A carbide part that has been protected with Seibu’s EL Coating results in longer tool life and more parts being produced. To activate EL Coating a simple M code is added to the CNC program. EL Coating is easy to use an available on all Seibu high precision wire EDMs.EL Coating Seibu
