Niobium-Titanium (Nb-Ti) alloy is composed two elements, niobium and titanium, which have extremely low cytotoxicity, and has excellent corrosion resistance. Moreover, Nb-Ti alloy has a Young’s modulus similar to that of human bone, and so is suitable as an implant material. Although manufacturing and shaping implants requires cutting processes to be performed, there has been no research on the cutting of Nb-Ti alloys, and the processing characteristics of Nb-Ti alloys have not yet been clarified. In the present study, the influences of tool material and cutting speed on tool life were investigated by milling of Nb-Ti alloy using a small ball end mill tool. The results of these investigations indicate that the tool life can be extended by using a diamond-coated tool and that a cutting speed of 8.0 m/s provides the longest tool life.
