Paper Abstract

People usually take the machining of elements with super- smooth surfaces just as a polishing process. But occasionally super-smooth polishing cannot be accomplished even conducted under a succeeded polishing procedure, resulting in the failure of obtaining super-smooth surfaces repeatedly. A concept of super-smooth surfaces machining 'process technology' is proposed which takes super-smooth surfaces machining as a system in general, not merely a polishing process. We take the machining of super-smooth surfaces as a chain consisted of some key nodes. The failure at any node will result in the failure of the final surfaces. The nodes in the process technology system refer to a series of key sub- items, such as sample material selection, pre-machining, and super-smooth surface evaluation, et al. With the aid of polishing experiments, the effects of some key sub-items are discussed.
