How much does the GF Machining Liechti g-Mill 1000 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 1000 sits in the middle of the g-Mill range: a 5-axis simultaneous machine for workpieces up to 1000 mm in diameter, with a 60 kW, 150 Nm spindle that turns to 30,000 rpm and a magazine of 60 tools. Nobody has yet tied this table to a current Liechti or GF Machining Solutions data sheet, so every value below is a listed figure to confirm with the supplier.
What separates it from the smaller Liechti g-Mill 850 is mostly capacity in the tool changer. The Liechti g-Mill 850 holds 40 tools; this machine holds 60, which matters when one setup has to rough, semi-finish and finish a complex part with separate cutters for each stage. Spindle torque rises from 120 Nm on the Liechti g-Mill 850 to 150 Nm here.
Going the other way, the Liechti g-Mill 1150 keeps the same 60-tool count and adds diameter, up to 1150 mm, with 65 kW and 160 Nm. A shop whose parts stay under 1000 mm gains little from that step, apart from a little more torque.
The HSK-A63 taper, 40 m/min rapids and 0.003 mm positioning figure are shared across these sizes. So are the Siemens Sinumerik 840D sl control, Liechti Turbosoft+ CAM and 80 bar through-spindle coolant. The listed weight of 22,000 kg (48,502 lb) is the number to give the foundation engineer.

Strengths & Limitations
Strengths
- 60-tool magazine, against 40 on the Liechti g-Mill 850, so complex parts can stay in one setup
- Spindle listed at 30,000 rpm, 60 kW and 150 Nm on an HSK-A63 interface
- Parts up to 1000 mm in diameter in 5-axis simultaneous machining
- High-pressure through-spindle coolant at 80 bar
Limitations
- Every figure comes from an unconfirmed table and must be checked against the supplier's current data sheet
- 150 Nm is light for large roughing cutters at low speed
- 22,000 kg (48,502 lb) of machine needs a suitable foundation and rigging access
- Positioning is listed at 0.003 mm; the table gives no repeatability or thermal figures to judge tighter work by

Frequently Asked Questions
01
Choose by part size. The Liechti g-Mill 1150 is listed for parts up to 1150 mm in diameter with a 65 kW, 160 Nm spindle and the same 60 tools. The g-Mill 1000 stops at 1000 mm with 60 kW and 150 Nm. If the parts fit, the smaller machine also brings less weight to install.
02
The listed tool capacity is 60, all on the HSK-A63 interface. The smaller Liechti g-Mill 850 holds 40. Sixty is enough for most single-setup 5-axis jobs that use separate roughing and finishing cutters plus drills and probes.
03
The table lists an HSK-A63 spindle running to 30,000 rpm, rated 60 kW (80 hp) and 150 Nm. It is a high-speed spindle: suited to small and medium cutters at high surface speed, less so to heavy low-speed roughing with large tools.
04
A Siemens Sinumerik 840D sl is listed, with Liechti Turbosoft+ as the CAM software. Because the table is not confirmed against a current manufacturer sheet, ask for the control version, options and software licence terms in the quotation.
