How much does the GF Machining Liechti Turbomill 1400g Twin cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.
Overview
The Liechti Turbomill 1400g Twin is listed as a 5-axis simultaneous machine with two independent spindles over a 1400 mm work zone. Each spindle is an HSK-A63 unit at up to 20,000 rpm, rated 55 kW (74 hp) and 170 Nm, and the 60-tool magazine is split 30 per spindle. Parts can be up to 300 mm in diameter. The figures here are listed values that have not been confirmed against a current Liechti or GF Machining Solutions specification.
This is the long version of the twin layout. Against the Liechti Turbomill 800g Twin, it adds work zone length, 1400 mm instead of 800 mm, and a stronger spindle pair, 55 kW and 170 Nm each instead of 50 kW and 150 Nm. Both twins share the 300 mm part diameter limit and the 30-tools-per-spindle split.
For a shop deciding between one long single-spindle machine and this twin, the listed figures frame the question clearly. The single-spindle Liechti Turbomill 1400g takes parts up to 450 mm and has 40 tools on one spindle, at 25,000 kg. The twin takes only 300 mm parts but works two at once, at 35,000 kg (77,162 lb).
That weight, spread over a long bed, is well above the 28,000 kg of the Liechti Turbomill 800g Twin. Rapids are 30 m/min and positioning is listed at 0.004 mm. The control is a Siemens Sinumerik 840D sl with Liechti Turbosoft+ CAM, and coolant reaches the cutters through the spindles at 80 bar.

Strengths & Limitations
Strengths
- Two independent 20,000 rpm HSK-A63 spindles, each listed at 55 kW and 170 Nm
- 1400 mm work zone, against 800 mm on the Liechti Turbomill 800g Twin
- 60 tools in total, 30 per spindle
- Machines two long parts at once, with 80 bar through-spindle coolant
Limitations
- Part diameter is limited to 300 mm, against 450 mm on the single-spindle Liechti Turbomill 1400g
- 35,000 kg (77,162 lb) over a long bed needs a major foundation
- 30 tools per spindle restricts complex programmes
- The table is unconfirmed against a current manufacturer specification

Frequently Asked Questions
01
The Liechti Turbomill 800g Twin has an 800 mm work zone, two 50 kW, 150 Nm spindles and weighs 28,000 kg. The Turbomill 1400g Twin has 1400 mm, two 55 kW, 170 Nm spindles and weighs 35,000 kg. Both take parts up to 300 mm in diameter with 30 tools per spindle.
02
The Liechti Turbomill 1400g takes parts up to 450 mm in diameter with 40 tools on one spindle. The twin limits parts to 300 mm and gives each spindle 30 tools, but runs two parts at once. If your parts fit 300 mm and repeat in volume, the twin is the one to quote.
03
The listed weight is 35,000 kg (77,162 lb). The foundation has to carry that over a long bed without sagging, so involve a structural engineer early and get the supplier's foundation drawing before any civil work.
04
Each of the two independent spindles is listed as HSK-A63, 20,000 rpm, 55 kW (74 hp) and 170 Nm, with 30 tools of its own. Coolant runs through both spindles at 80 bar.
