DIELECTRIC FLUID BATH AND FLOW CONTROL METHOD FOR ELECTRICAL DISCHARGE MACHINES

摘要

Apparatus for controlling flow within a bath (3) of dielectric fluid of an electric discharge apparatus for producing on the surface of an electrically conductive workpiece (21) a textured or matt finish wherein the apparatus comprises at least one nozzle (5a) for expelling fluid to fill the bath (3) to a predetermined dielectric fluid level (7); at least one nozzle (9a) for expelling fluid into the bath (3) to induce flow of the dielectric fluid contained therein; at least one baffle means (11, 23) to direct the flow of the dielectric fluid.
