Study on the Complex Tools Coating Technology by EDM
A kind of new complex tools coating technology by EDM (Electrical Discharge Machining) is studied in this paper. Firstly the principle of this technology is discussed. In order to meet the coating requirement of the high-speed steel twist drill, milling cutter or other complex tools, a set of coating device is designed and fabricated secondly, and the tools with different dimension are coated successfully by this device. Finally the performance evaluation of coated twist drills is carried out through the drilling test.
