The micro-EDM prototype was composed of three dimensional stage,transistor type isopulse generator with pulse duration of 80ns,and environmental maintaining system.

系由三维运动平台、带间隙伺服的加工头、纳秒级脉宽的等脉宽晶管脉冲电及环境保障系组成。

The result indicated that the material removal rate of isopulse generator is over 20% higher than that of general pulse generator.

实验结果表明，与普通脉冲电,等能量脉冲电可以提高加工效率20%以上。
