Development of Machining-Environment Controlled Advanced Machining System

在本研究项目中，为了建立未来纳米量级的超精密加工技术，首先，基于新的设计理念，开发了加工环境控制的超精密金刚石车床。该机床针对超精密反射镜在不同加工气氛和加工条件下的加工，验证了传统难加工材料钛铝合金在气控空间内超精密加工的有效性和有效性。结果表明，在冷冷却液中可以获得高质量的工件表面，且不会对金刚石刀具造成过大磨损。

In this research project, to establish the future ultra-precision machining technology of nano-meter order, at first, the machining-environment controlled ultra-precision diamond turning machine based on a new design concept was newly developed. The developed machine aims especially at the machining of the ultra-precision mirror under various machining atmosphere and machining conditions.Furthermore, the validity and effectiveness of ultra- precision machining of titanium ally, one of traditional hard-to-cut materials, within the atmosphere-controlled space were ascertained. As a result, the surface of the workpiece with high quality could have been obtained under cold coolant without considerable wear of diamond cutting tool.
