Turbine blades face extreme thermal and mechanical stresses, reaching up to 500 m/s with centrifugal forces around 550 t. Only high-temperature alloys like Inconel can withstand these forces. Complex blade geometries further increase the challenge. AccuGlobal tools minimise tool changes and chip-to-chip times while maintaining exceptional quality.
