Development of Machining-Environment Controlled Advanced Machining System

本课题为确立未来纳米级超精密加工技术，首先基于全新的设计理念，开发了加工环境控制的超精密金刚石车床。研制的机床专门针对各种加工气氛和加工条件下的超精密镜面加工。进一步验证了传统难加工材料钛合金在大气控制空间内超精密加工的正确性和有效性。因此，在冷冷却剂作用下，可以获得高质量的工件表面，而不会对金刚石刀具造成较大的磨损。

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.
