Overview
The GF Machining Solutions GF Machining Liechti go-Mill 600 is a compact 5-axis from the Liechti blisk family for individual turbine blades, vanes, and airfoils. Part dia: 600 mm (23.6 in), workzone: 600 mm. Target: mid-size compressor blades and turbine vanes.
The go-Mill series is Liechti’s platform for individual blade machining — handling complex airfoil geometry at high speed with absolute repeatability.
Spindle: 36,000 RPM HSK-E50 optimized for small ball-end mills. 32 kW (43 hp), 55 Nm torque for superalloy roughing and finishing.
Turbosoft+ CAM provides blade-specific strategies for thin-wall deflection and airfoil curvature. Siemens 840D sl for complex 5-axis interpolation.
Compact footprint for automated blade cells with robotic loading. Pricing: approximately $1,000,000 - $1,800,000.
