How much does the GF Machining Liechti g-Mill 1350 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 1350 is the largest g-Mill on this site, listed for 5-axis simultaneous work on parts up to 1350 mm in diameter. It pairs an 80-tool magazine with a 75 kW HSK-A63 spindle that reaches 30,000 rpm and 180 Nm. The figures have not been checked against a current Liechti or GF Machining Solutions specification, so they are listed values only.
Tool count is the clearest reason to pick this size. Eighty pockets let a large, feature-rich part be machined from roughing to final finish without reloading the magazine, where the Liechti g-Mill 1150 stops at 60. The spindle is also the strongest in the g-Mill listings, though 180 Nm on a 30,000 rpm spindle still means the machine favours fast cuts with moderate tools over low-speed hogging.
At 28,000 kg (61,729 lb), it is a significant installation. The foundation, the crane capacity at the delivery door and the transport route all need planning early.
The rest of the listed table matches the smaller g-Mill sizes: 40 m/min rapids, a 0.003 mm positioning figure, coolant through the spindle at 80 bar, a Siemens Sinumerik 840D sl control and Liechti Turbosoft+ for CAM programming.

Strengths & Limitations
Strengths
- 80-tool magazine, the largest listed in the g-Mill range
- Parts up to 1350 mm in diameter in 5-axis simultaneous machining
- 75 kW spindle with 180 Nm and a 30,000 rpm top speed on HSK-A63
- Coolant through the spindle at 80 bar with 40 m/min rapids
Limitations
- 28,000 kg (61,729 lb) of machine calls for a foundation study and heavy rigging
- 180 Nm on a high-speed spindle limits large-cutter roughing at low rpm
- The table is unconfirmed against a current manufacturer sheet, so all figures need checking before purchase
- No footprint, power or air figures are listed to plan the installation from

Frequently Asked Questions
01
Part size and tool count. The Liechti g-Mill 1150 is listed for parts to 1150 mm with 60 tools, 65 kW and 160 Nm. The g-Mill 1350 goes to 1350 mm with 80 tools, 75 kW and 180 Nm. If the larger magazine or envelope is not needed, the smaller machine is lighter to install.
02
The listed weight is 28,000 kg (61,729 lb). That figure drives the foundation design, the crane or skate capacity needed at delivery and possibly the route into the building, so get the supplier's installation drawing before any civil work starts.
03
HSK-A63, at up to 30,000 rpm. The listed rating is 75 kW (101 hp) and 180 Nm. HSK-A63 holders are common, which helps when moving tooling over from other high-speed 5-axis machines in the shop.
04
Positioning accuracy is listed as 0.003 mm (3 µm). The table does not give repeatability, the measuring standard or thermal behaviour, so ask the supplier how the figure was measured before relying on it for tolerance planning.
