中文摘要：
金属结构小孔在航空航天等领域中有大量应用，而电解加工是一种比较理想的小孔加工工艺。本文根据小孔电解加工的特点，采用侧壁绝缘成型金属管电极，在普通电解机床及直流电源加工基础上进行了提高小孔加工精度的试验研究，分析了侧壁绝缘与否、电流密度、阴极进给速度和阴极进给深度对小孔加工间隙的影响。结果表明：采用侧壁绝缘的阴极可加工出近似零锥度的小孔，采用小的电压和较大的阴极进给速度有利于减小小孔的侧面加工间隙，提高孔的加工精度。
英文摘要：
The metal parts with small-holes are widely used in the fields of aeronautics and astronautics. Electrochemical machining （ECM） processes provide a viable alternative for drilling small holes on metal parts with acceptable quality in numerous applications. This paper presents an ECM process of drilling small holes with side wall insulated anode by using a common ECM machine. Effects of several process factors, such as side wall insulation of anode, current density, anode feed speed and feed depth on the machining accuracy are investigated. The results show possibilities of improving the machining accuracy through utilizing anode with insulated side wall, smaller voltage and faster feed rates.
