摘要： An apparatus and process for forming surface layers on electrodes by electron discharge machining. A machining gap (7) , between an electrode (4) and a workpiece (5) is filled with a dielectric mixture containing metallic or submetallic powder. The apparatus uses a swinging mechanism to move the electrode (4) during processing. The apparatus uses a high-voltage superposition circuit to superpose a voltage of 100-400 V across the gap (7). The apparatus uses a current limiting resistor (R2) of 100-300 Ω to ensure that the main circuit supplies a low voltage of approximately 100 V to the machining gap (7).

摘要： An electrical discharge machining (EDM) apparatus having one or more dielectric tanks (50), each having one or more compartments (51,52), connected to an EDMing tank (3) by pipes, defining input and output dielectric paths and having selectively placed therein pumps (43,55,57,59) and control valves (53,54). The tanks (50) are used for containing dielectric during roughing and finishing operations. Filters (56,58) are used in the paths for removal of particles suspended in the dielectric. A filter loop with input and output paths containing a bidirectional filter (58) can be used to filter and store finishing powders from a finishing dielectric and to regenerate the finishing dielectric by backwashing the filter (58) with clean dielectric to replace the powder in the dielectric. Various combinations of inputs, discharge and filter paths may be used with various designs of dielectric tanks, having one or more compartments, in order to meet particular operational requirements. The operation of valves and filters in the disclosed invention can occur automatically, in response to the output from various detectors, positioned to identify respective system parameters.
