Overview
The GF Machining Solutions Liechti Turbomill 2000gx is a large-format 5-axis blade machining center with a 2,000 mm workzone designed for the largest turbine blades in aerospace and industrial gas turbine (IGT) production. With a recommended part diameter of 700 mm, the 2000gx handles oversized LP turbine blades, large IGT first-stage blading, and steam turbine components that exceed the capacity of 1,400 mm-class machines.
The gx designation represents Liechti's extended-capacity platform with the proven g-technology foundation — featuring 2g acceleration capability for high-dynamic simultaneous 5-axis blade profiling. The 2,000 mm workzone positions this machine at the top of the Turbomill range for single-spindle configurations alongside the 2600gx, serving the growing demand for larger, more efficient turbine blade designs.
The spindle delivers 20,000 RPM through an HSK-A63 interface with 60 kW (80 hp) continuous power and 200 Nm torque — the most powerful single-spindle configuration in the standard Turbomill family, scaled for heavy material removal on large superalloy blade blanks where stock removal volumes are significantly higher than on medium-sized blades.
Turbosoft+ CAM provides optimized strategies for large airfoil surfaces with extended chord lengths, complex root forms, and full shroud machining. The Siemens Sinumerik 840D sl control manages smooth simultaneous 5-axis interpolation across the full 2,000 mm travel. High-pressure through-spindle coolant at 80 bar ensures consistent chip evacuation across the extended cutting envelope.

Frequently Asked Questions
01
The 2000gx has a 43% larger workzone (2,000 vs 1,400 mm), 56% larger part diameter capacity (700 vs 450 mm), more spindle power (60 vs 55 kW), and heavier construction (35,000 vs 25,000 kg). It is designed specifically for blades that exceed the 1400g working envelope.
02
With a 2,000 mm workzone and 700 mm recommended part diameter, the 2000gx handles the largest LP turbine blades, oversized IGT blading, and large steam turbine blades. Actual capacity depends on blade geometry, fixturing, and root/shroud configuration.
03
The gx designation indicates the extended-capacity variant within Liechti's g-technology platform. The g refers to the g-technology with 2g acceleration capability, while the x denotes extended workzone beyond the standard g-series range (800g, 1400g).
04
Inconel 718, Waspaloy, Rene 80, Ti-6Al-4V, single-crystal nickel superalloys, cobalt-chrome alloys, and stainless steels. The 60 kW spindle with 200 Nm torque handles the heaviest material removal demands on these difficult aerospace materials.
