Overview
The Haas GM-1 is a gantry mill that carries a 40-taper spindle over a 123 × 53 in (3,124 × 1,346 mm) table, with travels of 121 × 61 × 16 in (3,073 × 1,549 × 406 mm). The table takes 6,000 lb (2,722 kg) and sits between columns 62 in (1,575 mm) apart. This is a machine sized by sheet and plate dimensions more than by part height.
The spindle is an inline direct-drive unit rated 30 hp (22.4 kW), 8,100 rpm and 90 ft-lbf (122 N·m) at 2,000 rpm, in CT or BT 40, cooled by a coolant jacket. That is a metal-cutting spindle, and the 30+1 side-mount tool changer accepts tools up to 11 in (279 mm) long and 12 lb (5.4 kg). The GM-1-5AX, by contrast, pairs 15 hp (11.2 kW) and 24,000 rpm with a BT30 taper.
Z travel is the figure to check first. At 16 in (406 mm), with the spindle nose between 2.5 in (64 mm) and 18.5 in (470 mm) above the table, the GM-1 is built for plate, sheet and low fixtures. The table itself is 1 in (25 mm) thick. Taller work belongs on the GM-2, which has 22 in (559 mm) of Z.
The axes are not alike. X rapids and cutting feed both top out at 800 ipm (20.3 m/min), while Y reaches 2,100 ipm (53.3 m/min) and Z 1,100 ipm (27.9 m/min). Thrust follows the opposite order: 4,498 lbf (20,008 N) on X, 1,645 lbf (7,317 N) on Y and 2,742 lbf on Z. Cuts limited by feed force therefore have the most margin along X.
Haas lists a starting price of US$199,995. The machine ships at 16,200 lb on an export pallet of 215 × 91 × 98 in (546 × 231 × 249 cm), and needs 70 A at 220 VAC or 35 A at 440 VAC three-phase.

Strengths & Limitations
Strengths
- 121 × 61 in (3,073 × 1,549 mm) of X and Y travel over a 123 × 53 in (3,124 × 1,346 mm) table that takes 6,000 lb (2,722 kg)
- 30 hp (22.4 kW) inline direct-drive spindle with 90 ft-lbf (122 N·m) at 2,000 rpm, in CT or BT 40
- 30+1 side-mount tool changer; tools to 11 in (279 mm) long and 12 lb (5.4 kg)
- Y-axis rapids of 2,100 ipm (53.3 m/min) and Z-axis rapids of 1,100 ipm (27.9 m/min)
- 62 in (1,575 mm) between columns, wider than the 53 in (1,346 mm) table
Limitations
- Z travel is 16 in (406 mm) and the spindle nose never rises more than 18.5 in (470 mm) above the table, which rules out tall parts and tall fixtures
- X-axis rapids and cutting feed are both capped at 800 ipm (20.3 m/min), so long moves take time on a 121 in (3,073 mm) axis
- 8,100 rpm top speed limits small-tool work in aluminium and composites; the GM-1-5AX runs to 24,000 rpm
- Y-axis thrust is 1,645 lbf (7,317 N), well under the 4,498 lbf (20,008 N) available on X
- A full magazine limits tools to 2.5 in (64 mm) diameter; 3.5 in (89 mm) is possible only with adjacent pockets empty

Frequently Asked Questions
01
X travel and table length. The GM-1XT has 142 in (3,607 mm) of X and a 144 × 53 in (3,658 × 1,346 mm) table. The GM-1 has 121 in (3,073 mm) of X and a 123 × 53 in (3,124 × 1,346 mm) table. Y travel of 61 in (1,549 mm), Z travel of 16 in (406 mm), the 30 hp (22.4 kW) 8,100 rpm spindle, the 30+1 tool changer and the 6,000 lb (2,722 kg) table load are the same on both.
02
The GM-2 is larger in every axis: 145 × 87.5 × 22 in (3,683 × 2,223 × 559 mm) of travel and a 144 × 72 in (3,658 × 1,829 mm) table, with the same 30 hp (22.4 kW), 8,100 rpm spindle and 6,000 lb (2,722 kg) table load. The GM-2 is slower along X, at 472 ipm (12 m/min) against the 800 ipm (20.3 m/min) of the GM-1.
03
Not as listed here: the table for the GM-1 shows X, Y and Z only. Haas lists the GM-1-5AX on the same 121 × 61 in (3,073 × 1,549 mm) X and Y travels, with 24 in (610 mm) of Z, B-axis travel of ±120° and a 15 hp (11.2 kW), 24,000 rpm BT30 spindle.
04
Z travel is 16 in (406 mm). The distance from spindle nose to table runs from 2.5 in (64 mm) to 18.5 in (470 mm), and the part, its fixture and the tool all share that space. Tools can be up to 11 in (279 mm) long, so a long tool leaves little height for the work.
05
Three-phase power at 220 VAC and 70 A or 440 VAC and 35 A. Air demand is 4 scfm at 100 psi (113 L/min at 6.9 bar) with at least 80 psi (5.5 bar) at the machine, through a 3/8 in hose and coupler. Coolant capacity is 95 gal (360 L).
