Cutting and machining Gr4 titanium alloy should be from the reduction of cutting temperature and reduce the bonding of two aspects, the choice of good red hardness, high bending strength, good thermal conductivity, and titanium alloy affinity poor tool materials, YG class carbide is more appropriate. Due to the poor heat resistance of high-speed steel, so should try to use the tool made of cemented carbide. Commonly used cemented carbide tool materials include YG8, YG3, YG6X, YG6A, 813, 643, YS2T and YD15.
