Abstract

This paper describes improvement of machining characteristics of sinking electrical discharge machining using a tool electrode which has micro holes for jetting dielectric liquid over the working surface. The tool electrode was made by diffusion bonding of copper plates over the interfaces on which micro grooves for jetting the dielectric fluid were formed using electrolyte jet machining. After bonding, a hemispherical shape was machined by turning. Using the tool electrode with dripping dielectric liquid, the processing time was shortened, and stability and accuracy of machining were improved compared with the conventional solid tool electrode.
