description The invention discloses a machining method of a turbine blade. The method comprises the following steps: firstly, clamping and positioning a precision casting blank by adopting a six-point positioning method, then machining the precision casting blank by adopting a high-precision sawtooth machining grinding wheel, welding a wear-resistant coating at a welding gap of a sawtooth working surface of the precision casting blank, and then grinding and polishing the precision casting blank so as to avoid the damage to an aluminized chromium layer during welding. After the process of aluminizing and chroming treatment is carried out on the precision casting blank, the to-be-machined area which does not need aluminizing and chroming treatment on the precision casting blank is prevented from being removed in the subsequent machining process, and leakage of a shielding layer of the to-be-machined area which does not need aluminizing and chroming treatment due to the fact that the temperature is too high in the aluminizi
