根据电火花微小孔加工的特点，利用WTDS型电致伸缩微位移器件驱动，根据仿生学的蠕动原理，研制一个尺寸为80mm×60mm×40mm的整体式电极直接驱动机构，由计算机控制可实现电极纳米尺度上的精确进给，并成功地应用到电火花加工中。
According to the characteristics of EDM micro-hole machining, the WTDS-type electrostrictive micro-displacement device is used to drive. According to the biomimetic creep principle, a monolithic electrode direct drive mechanism with the size of 80mm × 60mm × 40mm is developed, which can be controlled by computer Precise feed on the nanometer scale, and successfully applied to EDM.
