DIELECTRIC-FLOW-DIRECTING EDM ELECTRODE

摘要

An EDM electrode for directing dielectric flow to the gap, the electrode having a plug-shaped body with an axially displaceable machining end-face and including a high pressure biased circumferential cannelure in the body which is in fluidic communication with a fluid supply for introducing fluid to the gap and a sub-atmospheric pressure system for withdrawing the fluid from the gap.
