Abstract
The reaction layer at the surface of processed work has conventionally been perceived negatively as a sub-surface damage layer. However, in a recent study, the authors clarified that the ultra precise mirror surface finishing method could modify the work surface during grinding (removal process). This method is expected to produce various effects such as inducing an oxidization reaction on an active new surface immediately after processing, to thereby coat the surface with an anti-corrosion film, advantageously transforming the components of the tool or grinding fluid to the surface. This paper discusses applications of these latest techniques.
