Development of lath-type electro-chemical discharge machining for small insulated parts manufacturing

开发了一种利用车床式电火花加工机加工绝缘材料小零件的加工工艺。玻璃与电解液中的钠离子在放电热作用下发生化学反应，生成硅酸钠。在电解液中的溶解导致去除。当电极以恒速进给时，加工表面光滑。以加速度传感器的样机为例进行了试验。

A machining process by using the lathe-type electro-chemical discharge machine was developed for the fabrication of small parts made from insulated materials. After the chemical reaction of glass to sodium ion in electrolyte is accelerated by discharge heat, sodium silicate was generated. The dissolution in the electrolyte causes the removal. When an electrode was fed at a constant speed, the machined surface was smooth. A prototype of an acceleration sensor was made in trial as an example.
