Overview
The GF Machining Solutions Liechti Turbomill 2000gx Twin is a dual-spindle, large-format 5-axis blade machining center with a 2,000 mm workzone and twin independent spindle heads. With a recommended part diameter of 395 mm per spindle, the Twin configuration doubles roughing productivity on medium-diameter blades while leveraging the full 2,000 mm working envelope.
The dual-spindle architecture allows two blades to be roughed simultaneously, cutting cycle time nearly in half for production runs of identical blades. Each spindle operates independently with its own 5-axis kinematics, tool magazine, and coolant delivery. During finishing passes — where spindle dynamics and vibration isolation become critical — the machine can operate in single-spindle mode for maximum surface quality.
Each spindle delivers 20,000 RPM through an HSK-A63 interface with 60 kW (80 hp) continuous power and 200 Nm torque. The combined 120 kW installed spindle power makes the 2000gx Twin one of the most powerful dedicated blade machines available, targeting high-volume aerospace and IGT production lines where throughput directly impacts program economics.
Turbosoft+ CAM manages both spindles with synchronized and independent toolpath modes. The Siemens Sinumerik 840D sl control coordinates dual-spindle motion with collision avoidance across the shared workspace. High-pressure through-spindle coolant at 80 bar per head maintains chip evacuation performance on both cutting zones simultaneously.

Strengths & Limitations
Strengths
- Dual spindles double roughing productivity — two blades machined simultaneously in the 2,000 mm workzone
- 120 kW total installed spindle power makes this one of the most powerful dedicated blade machines available
- Each spindle operates independently with its own tool magazine and 5-axis kinematics
- Single-spindle mode available for finishing passes requiring maximum vibration isolation
- Turbosoft+ CAM manages synchronized and independent dual-spindle toolpath modes
- Proven Liechti architecture with collision avoidance across the shared workspace
Limitations
- At $4M-$6.5M, the dual-spindle premium requires very high blade production volumes to justify
- 45,000 kg machine weight requires extensive foundation engineering
- 395 mm per-spindle part diameter is smaller than the single-spindle 2000gx 700 mm capacity
- Dual-spindle programming complexity requires experienced Turbosoft+ operators

Frequently Asked Questions
01
The Twin has two independent spindle heads, each with 60 kW and 200 Nm torque, working simultaneously in the same 2,000 mm workzone. The trade-off is reduced per-spindle part diameter (395 vs 700 mm) because the workspace is shared between two cutting zones. Choose the Twin for high-volume production of medium-diameter blades; choose the single-spindle for the largest blade geometries.
02
Yes. During finishing passes where vibration isolation is critical for surface quality, one spindle can be parked while the other completes finishing operations. This flexibility allows the machine to optimize for both productivity (dual roughing) and quality (single finishing).
03
During roughing — which typically constitutes 60-70% of blade cycle time — dual-spindle operation nearly doubles throughput. The actual gain depends on blade geometry, material, and the proportion of roughing vs. finishing in the total cycle.
04
Inconel 718, Waspaloy, Rene 80, Ti-6Al-4V, single-crystal nickel superalloys, cobalt-chrome alloys, and stainless steels. Each spindle delivers 60 kW with 200 Nm torque for aggressive superalloy stock removal.
