电流变液性能分析及用于微器件精细加工的基础研究

Analysis of Electro-rheological Fluid and Development of Micro-tool for Micro-parts Machining

通过对粒子分散性电流变液组成、性能和电流变效应机理、电流变效应影响因素的分析,提出了基于电流变效应进行微细加工的微细砂轮制作新方法。在电场作用下电流变液与磨料微粒混合液形成粘弹性体,磨料微粒被约束和团聚在一起构成微小直径砂轮,改变传统固结磨料研磨工具所受到的限制,可用于玻璃等硬脆材料的微细加工。

This paper summarized the composition and performance of Electro-rheological Fluid(ER) , introduced the mechanism of ER effect and some influence factors on ER effect. A new-style of machining method based on ER effect to form a tiny grinding wheel was presented to accomplish superfine machining. Adding abrasive particles into ER fluid, a dynamic tiny grinding wheel that confines and reunites the abrasive particles will be formed. This method can be applied in polishing optics glass, changing the dimension restriction of the traditional bonded - abrasive grinding wheel。
