摘要：It is a difficult problem to fabricate deep and micro holes on the difficult-to-cut metals in the field of aviation manufacturing. The experimental research of electrochemical drilling technology with high-speed micro electrode for fabricating deep micro holes is carried out. The influences of rotary speed on machining precision and stability are studied. The holes, which the diameter is about 400μm, the aspect ratio is more than 10, and have steep wall and sharp edges were fabricated successfully on the nickelbase superalloys on self-developed high-precision micro-electrochemical machining system. It is proved that the high-speed electrochemical drilling process for fabricating deep and micro holes has a huge potential and broad application prospects. © (2014) Trans Tech Publications, Switzerland.
