How much does the GF Machining Liechti Turbomill 1400i 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 1400i is listed with a 1,400 mm (55.1 in) work zone and a 400 mm (15.7 in) maximum part diameter for 5-axis simultaneous machining on a single spindle. That spindle is an HSK-A63 unit reaching 20,000 rpm, rated 55 kW (74 hp) and 170 Nm, with 40 tools in the magazine. The table has not been checked against a current Liechti or GF Machining Solutions specification, so it stands as listed figures.
The obvious point of reference is the Liechti Turbomill 1400g, which shares the work zone length, the spindle and the tool count but is listed for 450 mm parts and weighs 25,000 kg. The 1400i takes smaller parts and is listed heavier, at 28,000 kg (61,729 lb). The table gives no reason for that difference, and what the i suffix means is not stated either, so a buyer should ask the supplier what the extra mass carries.
The same pattern appears at the shorter length: the Liechti Turbomill 800i is listed for 400 mm parts against 450 mm on the Liechti Turbomill 800g.
The rest of the listing is shared with the long Turbomills: 30 m/min rapid traverse, 0.004 mm positioning accuracy, 80 bar through-spindle coolant, a Siemens Sinumerik 840D sl control and Liechti Turbosoft+ for programming. On a used machine, confirm the as-built configuration against the original order documents.

Strengths & Limitations
Strengths
- 1,400 mm work zone on a single-spindle 5-axis machine
- HSK-A63 spindle at 20,000 rpm with 55 kW and 170 Nm
- 40-tool magazine for single-setup programmes on long parts
- Through-spindle coolant at 80 bar with a 0.004 mm positioning figure
Limitations
- Part diameter is listed at 400 mm, below the 450 mm of the Liechti Turbomill 1400g
- 28,000 kg (61,729 lb), heavier than the Turbomill 1400g with no listed reason
- 30 m/min rapids over a 1,400 mm stroke make repositioning slow
- The table has not been confirmed against a current manufacturer specification

Frequently Asked Questions
01
On the listed figures, the Liechti Turbomill 1400g takes parts up to 450 mm in diameter and weighs 25,000 kg. The Turbomill 1400i takes 400 mm and weighs 28,000 kg. Both have a 1,400 mm work zone, a 55 kW, 170 Nm spindle at 20,000 rpm and 40 tools.
02
The listed work zone length is 1,400 mm (55.1 in), with a maximum part diameter of 400 mm. Workholding at both ends takes some of that length, so check the full clamping arrangement on the supplier's drawing.
03
A single HSK-A63 spindle running to 20,000 rpm, listed at 55 kW (74 hp) and 170 Nm, with a 40-tool magazine. HSK-A63 tooling is shared with the g-Mill and other Turbomill machines in the Liechti listings.
04
The control version on the Siemens Sinumerik 840D sl, whether the Liechti Turbosoft+ licence transfers, the condition of the spindle and the 80 bar coolant system, and the foundation needed for the listed 28,000 kg (61,729 lb).
