Titanium alloy one has the characteristics of high strength, small specific gravity, corrosion resistance, low temperature resistance and high temperature resistance. According to its annealed structure, it can be divided into α-phase titanium alloy, β-phase titanium alloy, and α-β-phase titanium alloy. α-phase titanium alloy (TA type) cannot be strengthened by heat treatment, so the room temperature performance is not high, it has medium plasticity, and the machinability is fair. β-phase titanium alloy can obtain high room temperature performance through quenching aging treatment. The contact length between the chip and the front of the α β phase titanium alloy (TC type) is short, and the cutting force acts near the cutting edge. Due to the low thermal conductivity, the cutting edge temperature is high, which accelerates the wear of the drill and due to work hardening The phenomenon is more serious and the coefficient of elasticity is small, so the shrinkage of the drill hole is larger, which also affects the life of the drill bit.
