Stainless steel machined parts are widely used in semiconductor manufacturing, automobile and aerospace industry and so on. This study describes about the characteristics of SUS304 austenitic stainless steel machined surfaces by end milling and burnishing processing on the machining center. It is found by metallographic structure analysis by X-ray diffraction test for surface-hardened layers of steel that SUS304 which have originally austenitic structure before burnishing process is changed to martensitic structure. In this paper, relationship between burnishing conditions and metallographic structure was experimentally evaluated. As a result, relationship between hardness and martensitic structure of SUS304 is clearly observed by the ratio of austenitic and martensitic structures.
