Industry Context & Processing Challenges: Turbine disks and retaining rings made from nickel-base superalloys (Inconel 718, Waspaloy, Udimet 720) exhibit high heat resistance, low thermal conductivity, and intense work hardening. Cutting temperatures exceed 1000∘C, leading to rapid tool flank wear and notch formation.
Technical Requirements: Strict profile accuracy on dovetail slots, and zero surface micro-cracks or phase transformation layers.
ZWH Tooling Solutions & Value: ZWH high-rigidity whisker ceramic inserts (Al2O3+SiC) and multilayer AlTiN-coated carbide mills execute trochoidal slot milling and profile turning at high cutting speeds, providing high resistance to notch wear and thermal shock.
