采用动圈机构控制电极的进给，对电火花微细加工（钻削）的高速方法进行了实验研究。与电液系统或超声波振动工作液相比，该方法提高了钻削速度。由于加工时间非常短（例如，在0.5mm厚的铝板上加工0.20个孔需要8秒的时间，放电脉冲在非常精细的精加工范围内），因此需要快速响应的电极进给控制。可以在微加工范围内测量金属去除效率，并且对于不同的材料存在上限速度。在有色金属特别是黄铜中的微钻孔通过该工艺在商业上是可行的。
The paper is concerned with an experimental study on a high speed method of micro-machining (drilling) by EDM in which a moving coil (MC) mechanism was used for the feed control of the electrode. The drilling speed by this method is improved in comparison with either the electro-hydraulic system or the ultrasonic vibration to the working fluid. As the machining time is quite short (for example, 8secs time is required for 0.20 hole in a 0.5mm thick aluminum plate with the discharge pulses in very fine finishing range), a swift responsing electrode feed control is desirable. It is possible to measure metal removal efficiency in micro-machining range and there is an upper limiting speed for different materials. Micro-drilling in non-ferrous metal especially brass is commercially viable by the process.
