Overview

The Haas GM-1XT is the extended-table version of the GM-1 gantry mill, stretching the work envelope to handle even larger parts while maintaining the same 40-taper milling spindle and moving-bridge architecture. The XT designation indicates an extended table configuration that provides more usable machining area along the X-axis.

Travel is 3,683 mm (145 in) in X, 1,524 mm (60 in) in Y, and 279 mm (11 in) in Z. That extra 610 mm (24 in) of X-travel over the standard GM-1 covers full-length aerospace panels, boat molds, and architectural components that the base model cannot reach. The table extends to approximately 3,658 x 1,524 mm (144 x 60 in) with a 2,268 kg (5,000 lb) load capacity.

The spindle is the same 11.2 kW (15 hp) inline direct-drive unit running at 10,000 RPM with 62 Nm (46 ft-lbf) of torque through a CT/BT 40 taper. The 18+1 SMTC provides 1.75-second tool-to-tool changes. Rapids run at 30.5 m/min (1,200 ipm) on all axes.

Like the GM-1, the GM-1XT is built for composites, aluminum, plastics, and pattern materials rather than ferrous metals. The moving-bridge design keeps the workpiece stationary, which is essential for large, thin, or flexible parts that cannot be clamped to a moving table. The NGC control handles all standard Haas programming features.

At approximately $195,000-$250,000 configured, the GM-1XT costs roughly $25,000 more than the standard GM-1 for the extended table. For shops that need the extra X-travel for full-length composite layups, large mold patterns, or extended aluminum profiles, the GM-1XT eliminates the need for repositioning and ensures accuracy across the entire part length.

Strengths & Limitations

Strengths

3,683 mm (145 in) X-travel covers full-length aerospace panels and extended composite structures without repositioning
40-taper milling spindle provides proper tool rigidity for aluminum and composite milling beyond router-class capability
5,000 lb table load supports heavy fixtures and large workpieces across the extended table area
Moving-bridge gantry keeps workpiece stationary, critical for large, thin, or flexible composite structures
Same fast tool changes and NGC control as the standard GM-1 for consistent shop floor operation
Extended table adds only ~$25K over the base GM-1, making it cost-effective for shops that need the extra reach

Limitations

279 mm (11 in) Z-travel limits the machine to surface machining and profiling, not deep-cavity work
15 hp spindle is designed for composites and aluminum, not aggressive ferrous metal cutting
Extended footprint requires significantly more floor space than the standard GM-1
10,000 RPM spindle speed is lower than dedicated composite trimming machines with 20,000+ RPM

Best For

Aerospace composite trimming and profiling on full-length panels exceeding 10 feet Large mold and pattern making in foam, Ren Board, and epoxy tooling board Boat and marine manufacturers machining large hull molds and structural components Architectural fabricators cutting large aluminum and composite panels Shops that need GM-1 capability but require additional X-travel for full-length parts

Frequently Asked Questions

01 What does a new Haas GM-1XT cost?

Base price starts around $195,000. With options like through-spindle coolant, probing, and dust collection, a configured GM-1XT runs $220,000-$250,000. The XT extended table adds roughly $25,000 over the standard GM-1.

02 What is the difference between the GM-1XT and GM-1?

The GM-1XT extends X-travel from 3,073 mm to 3,683 mm (121 to 145 in) with a longer table. Same spindle, same tool changer, same control. The XT is for parts that need more than 121 inches of X-travel.

03 How does the GM-1XT compare to the GM-2-5AX?

The GM-2-5AX has similar X-travel (145 in) but adds 5-axis gimbal head capability with a 20,000 RPM HSK spindle. The GM-1XT is a 3-axis machine with a 40-taper spindle. The GM-1XT is for shops that need large-format 3-axis milling; the GM-2-5AX is for simultaneous 5-axis contouring.

04 Can the GM-1XT handle vacuum fixturing?

Yes. The large flat table is well-suited for vacuum fixtures, which are commonly used for holding thin composite panels and sheet materials. Haas offers vacuum table options and the NGC control supports vacuum system integration.
