The Leichti Turbomill 1400 g is an advanced turbine blade machine designed for fast, cost-efficient production of medium-to-large blades for jet engines and power generation. The machine’s configuration means that blades are clamped at each end of the machine and rotated between centres whilst a milling tool performs cutting operations
The motion creates complex airfoil contours, allowing the machine to perform heavy-duty roughing and dynamic finishing for the airfoil, root form, and shroud.
The machine rapidly creates complex profiles on the leading and trailing edges of the blades that control airflow into the engine while maintaining the tight tolerances that maximise fuel efficiency.
Acceleration and deceleration at 1g generate significant force – strong enough to topple the machine over if it is not securely anchored to the floor. The Liechti Turbomill 1400 g uses its large size, weight, and rigidity to resist these forces. Machine ways 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 is key to moving tools quickly around a blade’s leading and trailing edges.
The Liechti Turbomill 1400 g is aimed at OEMs and large Tier 1 manufacturers involved in high-volume turbine blade production - and is able to machine blades twice as fast as conventional and multi-purpose machines.
