How much does the GF Machining Liechti Turbomill 1400g 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 is listed as a long-bed, single-spindle 5-axis simultaneous machine: a 1400 mm work zone for parts up to 450 mm in diameter, cut by a 20,000 rpm HSK-A63 spindle rated 55 kW (74 hp) and 170 Nm. It carries 40 tools. The table on this page is a set of listed figures and has not been tied to a current Liechti or GF Machining Solutions data sheet.
Length is the reason to look at this machine. The Liechti Turbomill 800g has the same 450 mm part diameter but stops at 800 mm of work zone, with 50 kW and 150 Nm. Going to 1400 mm also brings a little more spindle, and the weight rises from 20,000 kg on the Liechti Turbomill 800g to 25,000 kg (55,116 lb) here.
Long, slender parts flex under cutting load, so the 170 Nm available is less often the limit than the part's own stiffness. Expect support, steady rests or careful toolpath strategy to decide how hard the machine can cut along the full length.
The 40-tool magazine is the same size as on the shorter Turbomills. Rapid traverse is listed at 30 m/min, which on a 1400 mm stroke means long repositioning moves take noticeable time. Positioning accuracy is given as 0.004 mm, with 80 bar coolant through the spindle, a Siemens Sinumerik 840D sl control and Liechti Turbosoft+ CAM.

Strengths & Limitations
Strengths
- 1400 mm work zone, against 800 mm on the Liechti Turbomill 800g
- Parts up to 450 mm in diameter
- 20,000 rpm HSK-A63 spindle with 55 kW and 170 Nm
- 80 bar coolant through the spindle
Limitations
- 30 m/min rapids make long repositioning moves over 1400 mm slow
- 40 tools is no more than on the shorter Turbomill machines
- 25,000 kg (55,116 lb) and a long bed need a substantial foundation
- The table has not been confirmed against a current manufacturer specification

Frequently Asked Questions
01
The Liechti Turbomill 1400i is listed with the same 1400 mm work zone and 55 kW, 170 Nm spindle, but for parts up to 400 mm and at 28,000 kg. The Turbomill 1400g takes 450 mm parts and is listed at 25,000 kg. Both carry 40 tools.
02
Usually the workpiece rather than the spindle. A part up to 1400 mm long and 450 mm across will deflect under load in its middle, so support and toolpath strategy decide the cut. The listed 170 Nm is enough for moderate roughing with HSK-A63 cutters.
03
The Liechti Turbomill 1400g Twin is listed with two independent 55 kW spindles, 60 tools split 30 per spindle and a 300 mm maximum part diameter, at 35,000 kg. It suits repeat parts that fit the smaller diameter.
04
The listed weight is 25,000 kg (55,116 lb). With a long bed, the foundation must be level and stiff over the whole length. Footprint, power and air are not in the listed table and should come from the supplier.
