How much does the GF Machining Liechti g-Mill 1150 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 g-Mill 1150 is listed as a 5-axis simultaneous machining center for parts up to 1150 mm across, driven by a 65 kW HSK-A63 spindle with 160 Nm of torque and a top speed of 30,000 rpm. The table on this page has not been confirmed against a current Liechti or GF Machining Solutions specification, so it should be treated as the listed figures and checked line by line with the supplier.
Its closest neighbour, the Liechti g-Mill 1000, has the same 60-tool magazine. The step up is therefore about the work envelope and the drive. The Liechti g-Mill 1000 is listed for 1000 mm parts with a 60 kW, 150 Nm spindle, while this machine takes 1150 mm with 65 kW and 160 Nm. Buyers whose largest part sits near the smaller machine's limit get some margin for fixtures and clamping here.
Above it, the Liechti g-Mill 1350 is listed with 80 tools, 75 kW and 180 Nm. If tool count is already tight at 60, that larger model may be the better fit even for parts that would physically fit in this one.
The listed machine weight is 25,000 kg (55,116 lb). Rapid traverse is 40 m/min, positioning is given as 0.003 mm, coolant is delivered through the spindle at 80 bar, and the control is a Siemens Sinumerik 840D sl with Liechti Turbosoft+ for CAM.

Strengths & Limitations
Strengths
- Part diameter up to 1150 mm, against 1000 mm on the Liechti g-Mill 1000, which leaves margin for fixtures
- 65 kW, 160 Nm spindle with a 30,000 rpm top speed
- 60 tool positions on an HSK-A63 interface
- 80 bar through-spindle coolant and 40 m/min rapid traverse
Limitations
- 60 tools, against 80 on the Liechti g-Mill 1350, which can force tool swaps on long programmes
- At 25,000 kg (55,116 lb) the machine weighs more than a light floor slab can take without assessment
- None of the figures has been confirmed against a current manufacturer sheet
- 160 Nm of torque still favours fast, light cuts over heavy low-speed roughing

Frequently Asked Questions
01
The listed maximum part diameter is 1150 mm (45.3 in). Leave room for the fixture and for the swing of the tool and head around the part in 5-axis moves when sizing the largest workpiece.
02
The Liechti g-Mill 1000 takes parts to 1000 mm with a 60 kW, 150 Nm spindle and weighs 22,000 kg. The g-Mill 1150 is listed at 1150 mm, 65 kW and 160 Nm, at 25,000 kg. Both hold 60 tools, run to 30,000 rpm and use HSK-A63.
03
Only to a degree. A 30,000 rpm spindle with 160 Nm is built for speed rather than low-speed torque. It will rough with moderate cutters, but large face mills and deep slotting in tough alloys should be trialled before the machine is chosen for that work.
04
The listed weight is 25,000 kg (55,116 lb), so a foundation assessment comes first. The table lists 80 bar through-spindle coolant but gives no electrical, air or footprint figures, which must come from the supplier's installation drawing.
