Research on NC Electrochemical Mechanical Drilling

Abstract:

NC electrochemical mechanical drilling was based on NC, Electrochemical machining and mechanical grinding. It drilled with different diameter composite cathodes. This kind of drilling method took the advantages of electrochemical mechanical, so it was not restricted by parts’ strength, hardness and stiffness. The cover of cathode ensured the drilling precision. So this technology should be studied. This paper took 304 stainless steel and high temperature alloy GH710 to do study, at last the reasonable and high efficient process parameters were found in the experiment. The high quality holes of better roundness and small taper angle were drilled. The results showed that the study of NC electrochemical mechanical drilling difficult-to-machine materials was very meaningful.
