610 Fundamental study on diamond burnishing process with rotary tool : Evaluation of burnished surface by glossiness measurement

Abstract

The effectiveness of a diamond burnishing method with rotating tool, which is proposed by the authors, is investigated. A developed hybrid-type parallel mechanism with spherical 5-degree-of-freedom range and force control was used as a burnishing machine. A diamond tipped tool, which is rotated by the high-speed-motor spindle, was used as a burnishing tool. A hardened die steel surface was targeted. The fundamental characteristics of the proposed method were evaluated by the surface profile, appearance of the burnishing mark and glossiness of the burnished surface, and the advantages of the proposed method were clarified by comparing with the conventional method, which is without the tool rotation.
