Overview
The Haas GM-1-5AX is a 5-axis gantry mill with 121 × 61 × 24 in (3,073 × 1,549 × 610 mm) of travel over a 123 × 53 in (3,124 × 1,346 mm) table. Both rotary axes belong to the spindle head, so sheet, plate and long extrusions lie flat on the table while a 24,000 rpm BT30 spindle is tilted and swivelled around them. Haas lists a starting price of US$299,995.
The head defines what the machine can do. B tilts ±120° at up to 105°/sec, and C rotates ±245° at 100°/sec, which means a finite swivel that has to unwind, not continuous rotation. Drive torque is 112 ft-lbf (152 N·m) on B and 210 ft-lbf (285 N·m) on C, with brakes rated 100 ft-lbf (136 N·m) and 190 ft-lbf (258 N·m). Those are small numbers, and they match the spindle: 15 hp (11.2 kW), liquid cooled, with 11 ft-lbf (14.9 N·m) of torque at 5,500 rpm. This is a machine for small cutters at high speed in aluminium, plastics and composites, not for roughing steel.
Feed figures are uneven across the axes. X, the long axis, rapids at 800 ipm (20.3 m/min), which is also the maximum cutting feedrate. Y rapids at 2,100 ipm (53.3 m/min) and Z at 1,100 ipm (27.9 m/min). Thrust follows a different pattern: 2,520 lbf (11,210 N) on X, 2,050 lbf (9,119 N) on Z and 1,020 lbf (4,537 N) on Y. Spindle nose to table runs from 5 in (127 mm) to 29 in (737 mm), and the gap between the columns is 62 in (1,575 mm).
The 30+1 side-mount tool changer is sized for the BT30 taper. A tool can be 2 in (51 mm) in diameter with every pocket full, 7 in (177 mm) long and 5.5 lb (2.5 kg). The table is rated for 6,000 lb (2,722 kg), and the plate itself is listed at 1 in (25 mm) thick. If the part is longer, the GM-1XT-5AX has 142 in (3,613 mm) of X on the same Y and Z.

Strengths & Limitations
Strengths
- 24,000 rpm liquid-cooled integral spindle with a BT30 taper, suited to small tools at high surface speed
- Two-axis head: B tilts ±120° at 105°/sec and C swivels at 100°/sec, so five-sided work is done on a part that never leaves the table
- 121 × 61 in (3,073 × 1,549 mm) of X and Y travel over a 123 × 53 in (3,124 × 1,346 mm) table rated for 6,000 lb (2,722 kg)
- Y rapids of 2,100 ipm (53.3 m/min) and Z rapids of 1,100 ipm (27.9 m/min)
- Runs from a 40 A supply at 220 VAC three-phase, or 20 A at 440 VAC, and uses 4 scfm of air at 100 psi (113 L/min at 6.9 bar)
Limitations
- Spindle torque is 11 ft-lbf (14.9 N·m) at 5,500 rpm from 15 hp (11.2 kW), which rules out heavy roughing and large cutters in steel
- X rapids and cutting feed are both capped at 800 ipm (20.3 m/min), so long traverses along the 121 in (3,073 mm) axis are the slow part of a cycle
- BT30 tooling is limited to 2 in (51 mm) in diameter, 7 in (177 mm) in length and 5.5 lb (2.5 kg); 4 in (102 mm) cutters need the adjacent pockets empty
- Z travel is 24 in (610 mm) and the spindle nose reaches no higher than 29 in (737 mm) above the table, so tall parts leave little room once the head is tilted
- C-axis travel is ±245°, so the head cannot keep rotating in one direction

Frequently Asked Questions
01
B and C, both in the spindle head. B tilts ±120° at up to 105°/sec with 112 ft-lbf (152 N·m) of torque and a 100 ft-lbf (136 N·m) brake. C rotates ±245° at up to 100°/sec, with 210 ft-lbf (285 N·m) of torque and a 190 ft-lbf (258 N·m) brake. Haas's listing gives no rotary figures for the table.
02
An integral spindle and motor with a BT30 taper: 24,000 rpm, 15 hp (11.2 kW) and 11 ft-lbf (14.9 N·m) at 5,500 rpm. It is liquid cooled with grease-packed bearings. The torque figure is low, so plan on small-diameter tools and light radial engagement, not heavy cuts.
03
The side-mount changer holds 30+1 tools. With all pockets full the limit is 2 in (51 mm) in diameter. Haas lists 4 in (102 mm) when the adjacent pockets are left empty. Maximum tool length is 7 in (177 mm) and maximum tool weight is 5.5 lb (2.5 kg).
04
Only in length. The GM-1XT-5AX has 142 in (3,613 mm) of X travel and a 144.3 × 53 in (3,664 × 1,346 mm) table, against 121 in (3,073 mm) and 123 × 53 in (3,124 × 1,346 mm) here. Y and Z travel, the spindle, B and C travel, the feedrates and the 6,000 lb (2,722 kg) table rating are listed the same on both.
05
220 VAC three-phase at 40 A, or 440 VAC three-phase at 20 A. Compressed air consumption is 4 scfm at 100 psi (113 L/min at 6.9 bar), and the supply must hold at least 80 psi (5.5 bar). The hose and coupler are 3/8 in. Coolant capacity is 95 gal (360 L).
