Powder sedimentation rate has an important influence to powder mixed dielectric, and which is a man factor to realize powder mixed dielectric mirror EDM. In this paper, the influence effects of several kinds additive of polymeric epoxy ethane and aryl hydrocarbon are experimentally researched. It is shown that as one kind of additive, aryl hydrocarbon can reduce the powder sedimentation rate. By using the additive material and additive consistency used in the experiment, the machining effects of powder mixed dielectric are clearly improved and the mirror EDM using powder mixed dielectric is realized.
