ABSTRACT:
A workpiece having a surface of revolution to be machined by electrical discharge is encased by a housing while being rotated in a dielectric liquid bath in spaced relation to a matrix electrode. The workpiece containing cavity of the housing is formed with a machining zone slot through which surface traces of the workpiece are brought into registration with a matrix surface of the electrode, the clearance between one edge of the slot and an EDM machined area of the workpiece defining an inlet through which the dielectric fluid is inducted to the interior of the housing. A portion of the cavity is larger than the workpiece providing a plenum for relatively free passage of the metal particulate entraining liquid, which is exhausted through an outlet port of the housing to be pumped to the sump of the EDM machine. The remaining portion of the cavity is closely matingly complementary to the surface of revolution, only slightly larger in radius than the workpiece, and the unmachined area or radially outwardly projecting portions of the machined area standing out in relief restrict or impede circulation of the liquid reversely around the workpiece and back towards the machining zone slot.
