EDM Electrode Guides

Though of middling performance when compared to silicon nitride guides, conventional ceramic guides are more than capable when it comes to run-of-the-mill EDM drilling jobs. Conventional ceramic guides are ideal for machine shops that have unpredictable jobs with short production runs, where any number of different guide types may be needed at a moment's notice.

Formation of a new EDM electrode material using sintering techniques

The performance of the EDM process, to a large extent, is dependent on the material and the design of the electrodes. EDM electrode material must have basic properties such as electrical and thermal conductivity, a high melting temperature, low wear rate, and resistance to deformation during machining.

Conventional EDM vs Wire EDM

EDM uses tools of graphite or soft metal as electrodes and runs voltage through them to generate high-frequency spark discharges. During machining, both the electrode and the material being worked are typically submerged in a bath of dielectric fluid, which cools the electrode and workpiece, acts as a current conductor and flushes out debris.
