Technique of ECM Deburring for Intersecting Holes of Pump

Abstract:

Most recently automobile pumps contain intersecting holes. However, there has been no efficient method for burr at intersecting holes. The theory of electrochemical deburring for high pressure pump body is firstly introduced. Then math model of ECM deburring and cathode model are built. Experiment results indicate that the technique can effectively remove the burrs of the hole and regulate the corner radius of injection holes. The smooth transition circle could be obtained around the conjunction of the hole, thus ECM deburring method can effiectively increase cleanliness of injector body and make the whole injector more stable.
