Turbine blades are high-precision components with a size of 60x60cm, fabricated from robust materials such as 65Mn, 1.1221, C60, Gr15, SUJ2, and 100Cr6. Engineered to a remarkable precision of 0.005mm, these blades are crafted using advanced processing techniques including CNC turning, CNC milling, wire cutting, and grinding. To enhance strength and durability, they undergo heat treatments like carbonitriding and hardening to achieve a hardness level of HRC40-45.
