Overview
The Haas GM-1XT is the extended-X version of the GM-1 gantry mill, with 142 in (3,607 mm) of X travel over a 144 × 53 in (3,658 × 1,346 mm) table. Y and Z are unchanged at 61 in (1,549 mm) and 16 in (406 mm). The added length is for long plate, extrusions and beams that the GM-1, at 121 in (3,073 mm) of X and a 123 × 53 in (3,124 × 1,346 mm) table, cannot take in one setup.
None of the other headline figures moves with the stretch. Table load stays at 6,000 lb (2,722 kg), now spread over a longer table, and 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.
Length makes the X-axis speed more noticeable. Rapids and cutting feed on X are both 800 ipm (20.3 m/min), while Y moves at 2,100 ipm (53.3 m/min) and Z at 1,100 ipm (27.9 m/min). Programs that keep the cutter working along X and step over in Y waste less time than ones that rapid up and down the bed. Thrust is 4,498 lbf (20,008 N) on X, 1,645 lbf (7,317 N) on Y and 2,742 lbf on Z.
For a wider or taller envelope the next step is the GM-2, with 87.5 in (2,223 mm) of Y, 22 in (559 mm) of Z and a 144 × 72 in (3,658 × 1,829 mm) table, though its X axis is limited to 472 ipm (12 m/min). The HDC-3 is a different class of machine: 60 hp (44.7 kW), a 50-taper spindle and a 10,000 lb (4,536 kg) table load.
Haas lists a starting price of US$239,995 for the GM-1XT. The table gives no shipping weight or crate size for this model, so ask for them before planning rigging.

Strengths & Limitations
Strengths
- 142 in (3,607 mm) of X travel and a 144 × 53 in (3,658 × 1,346 mm) table, against 121 in (3,073 mm) and 123 × 53 in (3,124 × 1,346 mm) on the GM-1
- Table load of 6,000 lb (2,722 kg), the same rating as the GM-1
- 30 hp (22.4 kW), 8,100 rpm inline direct-drive spindle with 90 ft-lbf (122 N·m) at 2,000 rpm
- 30+1 side-mount tool changer handling tools to 11 in (279 mm) and 12 lb (5.4 kg)
- 62 in (1,575 mm) between columns and 61 in (1,549 mm) of Y travel span the full 53 in (1,346 mm) table width
Limitations
- X rapids of 800 ipm (20.3 m/min) are slow for a 142 in (3,607 mm) axis; Y runs at 2,100 ipm (53.3 m/min)
- Only 16 in (406 mm) of Z, with 18.5 in (470 mm) maximum from spindle nose to table
- No shipping weight or crate dimensions appear in Haas's table for this model
- The 8,100 rpm ceiling limits small-diameter tooling; the GM-1XT-5AX has a 24,000 rpm spindle but only 15 hp (11.2 kW)

Frequently Asked Questions
01
The GM-1XT has 142 in (3,607 mm) of X travel and a table 144 in (3,658 mm) long. The GM-1 has 121 in (3,073 mm) of X and a 123 in (3,124 mm) table. Both are 53 in (1,346 mm) wide with 61 in (1,549 mm) of Y, 16 in (406 mm) of Z and a 6,000 lb (2,722 kg) table load.
02
When the part is wider or taller. The GM-2 has 145 in (3,683 mm) of X, close to the 142 in (3,607 mm) here, but 87.5 in (2,223 mm) of Y and 22 in (559 mm) of Z on a 144 × 72 in (3,658 × 1,829 mm) table. GM-2 rapids on X are 472 ipm (12 m/min) against 800 ipm (20.3 m/min) on the GM-1XT. Spindle rating and table load are the same on both.
03
An inline direct-drive spindle in CT or BT 40, rated 30 hp (22.4 kW) and 8,100 rpm, with 90 ft-lbf (122 N·m) of torque at 2,000 rpm. Bearings are lubricated by air/oil injection and the spindle is cooled by a coolant jacket. The 5-axis GM-1XT-5AX uses a different spindle: 15 hp (11.2 kW), 24,000 rpm, BT30.
04
The side-mount changer holds 30+1 tools. With every pocket full, a tool can be 2.5 in (64 mm) in diameter; with the adjacent pockets empty the limit is 3.5 in (89 mm). Maximum length is 11 in (279 mm) and maximum weight 12 lb (5.4 kg).
05
