Ti alloy has been conventionally used for parts of air plane or chemical equipment, because it is tough and has low specific gravity, and has high anti-corrosion characteristic. Furthermore, the material is very flexible to human living body cells and there are few allergic reactions as a medical application. These characteristics of Ti alloy are most suitable for a dental implant or a total hip prosthesis, and recently a lot of Ti alloy has been used for many medical applications. Furthermore, generation of textured surface of several micron meter level on the dental implant of Ti alloy is extremely effective to improve the fusion characteristics of the living body cell from the recent dental studies. However, Ti alloy is a difficult to machine material, the tool wear is extremely high and precision texturing by cutting is very difficult. In this study, Ti alloy was face turned by some kind of tool materials such as single crystal diamond, cBN, tungsten carbide and CVD-SiC, and the tool wear characteristics and surface roughness changes were evaluated experimentally. Finally cutting tests of micro textured patterns were carried out by the fabricated micro cutting tool of polycrystalline cBN (PCBN) tool and feasibility of the micro tool for the texturing was studied.
