Liechti Turbomill 1400 g Roughs and Finishes Medium, Large Turbine Blades

For jet engine and power generation turbine blades up to 1.4 meters in length, the Liechti Turbomill 1400 g from GF Machining Solutions produces high-quality finished part surfaces that require minimal polishing and less benchwork than those processed on general-application machines. To provide fast, cost-efficient production, the Turbomill 1400 g clamps blades at each end and rotates them between centers for heavy-duty roughing and dynamic finishing of complex airfoil contours, root forms and shrouds.

With the growing demand for greater fuel efficiency, tighter tolerances are required, and GF Machining Solutions’ Liechti Turbomill 1400 g airfoil machining platform can effectively handle those challenges. The machine quickly generates complex profiles on the leading and trailing edges of the blades that control airflow into the engine while maintaining the tight tolerances that maximize fuel efficiency.

While most machine tools boast significant acceleration/deceleration rates in simple straight-line machine movements, the Turbomill 1400 g delivers 1g acceleration/deceleration rates for three-dimensional machining paths. Such speeds generate significant force – strong enough to topple the machine if not securely anchored to the shop floor. The Turbomill 1400 g uses its large size, weight, and rigidity to counter these forces.

Machine paths are engineered with the strength to handle extreme momentum and inertia. The X axis moves via a linear drive, the Y and Z axis on ball screws, and direct-drive motors power the rotary B and A axes, which are key to moving tools quickly around a blade’s leading and trailing edges.
