How much does the GF Machining Liechti go-Mill 350 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 go-Mill 350 is the compact end of the go-Mill listings: a 5-axis simultaneous machine for parts up to 350 mm in diameter and 505 mm along the work zone, with a 36,000 rpm HSK-E50 spindle. Its table also carries turning limits of 350 mm diameter and 505 mm length, matching the milling envelope. The figures are listed values that have not been checked against a current Liechti or GF Machining Solutions data sheet.
The spindle is small and fast. At 25 kW and 40 Nm on an HSK-E50 interface, it is meant for small cutters at high surface speed rather than for heavy stock removal, and the HSK-E50 holders it takes are a different family from the HSK-A63 used on the g-Mill and Turbomill machines. A shop moving between them will need separate tooling stock.
Axis speed is the other notable figure. Rapids are listed at 50 m/min and positioning at 0.002 mm, against 40 m/min and 0.003 mm for the larger Liechti g-Mill 850. With 30 tools in the magazine, the machine suits short and medium programmes on small parts.
The listed weight of 8,000 kg (17,637 lb) is well below the 12,000 kg of the Liechti go-Mill 600. The machine is listed with a Siemens Sinumerik 840D sl control, Liechti Turbosoft+ CAM and 80 bar coolant through the spindle.

Strengths & Limitations
Strengths
- 36,000 rpm HSK-E50 spindle suited to small cutters at high surface speed
- Listed rapids of 50 m/min and a 0.002 mm positioning figure
- Turning limits of 350 mm diameter and 505 mm length are listed alongside the milling envelope
- 8,000 kg (17,637 lb) is a lighter installation than the larger go-Mill and g-Mill machines
Limitations
- 25 kW and 40 Nm limit the machine to light cuts with small tools
- Only 30 tool positions for complex single-setup jobs
- HSK-E50 tooling is not shared with the HSK-A63 machines in the Liechti range
- The listed table has not been confirmed against a current manufacturer specification

Frequently Asked Questions
01
The listed maximum part diameter is 350 mm and the work zone length is 505 mm. The turning limits are given as the same 350 mm diameter and 505 mm length. Fixtures and clamping take part of that envelope, so check the full setup against the supplier's drawing.
02
The table does not say why. HSK-E50 is a smaller interface generally used on high-speed spindles, which fits the listed 36,000 rpm, 25 kW and 40 Nm. In practice it means HSK-A63 holders from other machines in the shop will not fit.
03
The Liechti go-Mill 600 is listed for 600 mm parts and a 600 mm work zone, with 32 kW, 55 Nm and a weight of 12,000 kg. The go-Mill 350 is listed at 350 mm, 505 mm, 25 kW, 40 Nm and 8,000 kg. Both have 36,000 rpm, HSK-E50, 30 tools and 50 m/min rapids.
04
A floor rated for the listed 8,000 kg (17,637 lb) and room for the high-pressure coolant system, which runs at 80 bar through the spindle. Power, air and footprint are not in the listed table and need to come from the supplier.
