What to Look for When Buying a Used Liechti
Verify the spindle and ultra-dynamic axis system. Liechti machines are built for high-speed cutting of titanium, inconel, nimonic, titanium-aluminide, and high-alloy steels in single-clamping airfoil production, so motor spindle health is the first item to check. Test runout, listen for bearing noise, and confirm thermal stability after warm-up. Verify all linear and rotary axes for high-jerk capability and zero backlash. On Turbomill 500g and other current platforms, cycle the rigid axis layout through full travel and confirm dynamic positioning accuracy.
Inspect the rotary table, tilting axis, and bar feeder. On the g-Mill and Turboblisk platforms, the tilted rotary table and horizontal spindle configuration are essential for complete blisk machining in one setup. Verify the trunnion or tilt axis indexes accurately and clamping is rigid. On Turbomill machines equipped with bar feeders, test the bar feed system for reliable handoff. Check root machining, threading, chamfering, engraving, and brushing accessory functions if equipped, since Turbomill platforms are designed to complete the full blade in a single setup.
Check TurboSoft plus software, probing, and process integration. Liechti machines run on the proprietary TurboSoft plus parametric CAM software for airfoil and blisk tool-path generation. Confirm the TurboSoft plus license, post-processors, and existing blade/blisk part programs transfer with the machine. Verify probing systems for adaptive machining of welded blisks and the ability to scan mid-span, chord, and other airfoil features. Coolant filtration is critical given titanium and nickel-superalloy work — confirm filtration, mist extraction, chiller, and high-pressure through-spindle coolant operate.
Liechti Turbomill Blade Machining Centers
Turbomill 500g (Current Flagship)
The Turbomill 500g is Liechti's current flagship 5-axis airfoil machining center for medium-sized turbine blades, setting the benchmark in profile accuracy and trailing-edge quality. The machine produces a complete blade in one setup including bar feeding, 5-axis simultaneous milling, turning, root machining, threading, chamfering, engraving, and brushing, with a rigid compact axis layout that supports high-jerk machining without vibration marks.
Turbomill Series with g-Technology
The first Turbomill with g-technology launched in 2008, extending the original 1994 Turbomill platform with the g-Mill's high-dynamic machining concept. Earlier Turbomill generations remain widely deployed in aerospace and power generation, used for medium-sized turbine blades in titanium and nickel superalloys. All Turbomill machines support roughing and finishing of airfoil, hub, and shroud in one setup, plus probing and adaptive machining of mid-span, chord, and additional features.
Liechti Turboblisk & g-Mill Blisk Centers
Turboblisk (5- and 6-Axis Blisk Machining)
The Turboblisk, launched in 1997, is the dynamic 5- and 6-axis machining concept dedicated to integrally bladed disks (blisks and IBRs) for aircraft engine compressor and fan stages and gas-turbine rotors. The 6-axis configuration enables complex airfoil access and complete blisk machining in one setup, supporting roughing and finishing of all airfoil surfaces, hub fillets, and edge profiles.
g-Mill (5-Axis Simultaneous Blisk Center)
The g-Mill, launched in 2002, is a 5-axis simultaneous airfoil machining center designed specifically for blisk production. The tilted rotary table and high-acceleration horizontal spindle configuration deliver complete blisk machining in one setup, with a rigid frame that produces chatter-free leading and trailing edge quality without vibration marks. The g-Mill supports roughing and finishing of the airfoil in one setup plus probing and adaptive machining of welded blisks, all programmed in TurboSoft plus.
How to Sell Your Used Liechti
Liechti machines hold strong resale value due to the brand's worldwide leadership in 5-axis airfoil machining for aerospace and power generation, the small global installed base of dedicated blade and blisk machines, and ongoing OEM parts and applications support through GF Machining Solutions. Low-hour Turbomill 500g, g-Mill, and Turboblisk machines with current TurboSoft plus licenses and full fixturing are in particularly high demand on the secondary market.

Frequently Asked Questions About Used Liechti Machines
Are used Liechti milling machines reliable?
Yes. Liechti has built Swiss precision machinery since 1865 and is the worldwide market leader in 5-axis airfoil machining for aerospace and power generation. Turbomill, Turboblisk, and g-Mill platforms are built for ultra-dynamic continuous production of titanium and nickel-superalloy turbine components. Parts and applications support are available through GF Machining Solutions.
What CAM software does Liechti use?
Liechti machines run TurboSoft plus, the proprietary parametric CAM software Liechti developed in 1987 specifically for 5-axis airfoil machining. TurboSoft plus generates optimized tool paths and process parameters for blade and blisk production and is a critical part of any used Liechti package — confirm license transfer, post-processors, and existing part programs are included.
What should I inspect before buying a used Liechti?
Focus on motor spindle health, linear and rotary axis dynamics (high-jerk machining), tilted rotary table and tilt axis (g-Mill, Turboblisk), bar feeder and accessory functions on Turbomill, probing systems, TurboSoft plus license and part-program library, and coolant filtration plus through-spindle high-pressure systems for titanium and nickel-alloy work.
Which Liechti models hold their value best?
Turbomill 500g flagship blade centers, low-hour g-Mill blisk centers, and Turboblisk 6-axis machines hold the strongest residual values, driven by aerospace engine and power-generation turbine demand. Machines with current TurboSoft plus licenses and complete blade/blisk fixturing command additional premium. Call (844) 478-8181 for valuations.
What is the difference between Turbomill and g-Mill?
Turbomill is Liechti's 5-axis blade machining platform for medium-sized turbine blades, with bar feeding, 5-axis milling, turning, and root machining in one setup. g-Mill is the 5-axis blisk platform with a tilted rotary table and horizontal spindle for complete blisk production in one setup. Turbomill targets blades; g-Mill targets blisks. Turboblisk extends to 6-axis dynamic blisk machining.
