A study on the Ultra-precision Inner Cutting of Al-alloy

알루미늄합금의 초정밀 내면절삭

Recentlry, High accuracy and precision are required in various industrial field. To obtain the surface roughness with range from several 10nm to several nm in inner cutting, we need a ultra-precision machine, single diamond tool, cutting condition, and the study of materials. It is very difficult to obtain the mirror surface without new technique. In this paper, Using the new tool holder as well as the ultra precision diamond cutting, we directly processed the inside of an aluminum alloy in order to obtain mirror surface. We have considered the length of tool holder when we design the tool holder. From experimental results, we believe that the new tool holder will improve inner cutting.
