In order to improve resource utilization, researches should increase investment in science and technology, vigorously develop further processing antimony products with strong market competitiveness, well outlook, high technology, high added value and gradually occupy the market, form a batch of new materials and industrial structure and expand its related applications, and ultimately change our antimony products with the extensive primary structure, and change resources advantage to the industrial advantages, and achieve steady and rapid economic development [1].
Nano-materials possess many unique properties and thereby have broad application prospects in catalysis, filter, optical absorption, magnetic media, and new materials [2, 3], so the majority of materials researchers has carried out extensive research about preparation, properties and application of nano-materials.

Introduction Diamond and cubic boron nitride (cBN) are well known as superhard materials. cBN is the only suitable superhard material for machining steel materials and ferrous elements workpieces as its inert properties with ferrous elements.
So it has excellent performance in high speed, high efficiency and super-precision machining, and is the most excellent tool materials to be studied in advanced industrial countries and is applied widely [1-2].

Material of any hardness can be cut as long as it is conductive.
The second DC power supply use ultracapacitor bank to improve the gap current for optimum material removal rate.
At this moment the discharge is happened, the gap voltage is dropped around 20-30 V and depends on the materials of electrode and workpiece [4].
