Haas Automation vs Haas Automation · 5-Axis Machining Centers
Summary
The Haas GM-2-5AX and Haas VS-3-5AX are both large-format 5-axis machines with 20,000 rpm HSK-A63 spindles, aimed at composite trimming, aluminum profiling and mold and pattern work. The GM-2-5AX covers a wider area, with 87.5 in (2,223 mm) of Y travel and a 144 × 72 in (3,658 × 1,829 mm) table; the VS-3-5AX is the deeper, heavier-duty machine.
The VS-3-5AX has 50 in (1,270 mm) of Z travel against 39.3 in (998 mm), a 29 hp (21.6 kW) spindle against 16 hp (12 kW), 20 ft-lbf @ 7,500 rpm against 11.3 ft-lbf, 70+1 tools against 30+1, and a 10,000 lb (4,536 kg) load against 6,000 lb (2,722 kg). The GM-2-5AX rapids faster, at 472 ipm (12 m/min) against 360 ipm (9.1 m/min). Haas lists them at US$399,995 and US$788,995.

Advantages
Haas GM-2-5AX
- 87.5 in (2,223 mm) of Y travel against 50 in (1,270 mm)
- 472 ipm (12 m/min) rapids against 360 ipm (9.1 m/min)
- Lower published list price, US$399,995 against US$788,995
Haas VS-3-5AX
- 29 hp (21.6 kW) spindle against 16 hp (12 kW)
- 70+1 tools against 30+1
- 50 in (1,270 mm) of Z travel against 39.3 in (998 mm)
- 10,000 lb (4,536 kg) load against 6,000 lb (2,722 kg)
Verdict
Choose the GM-2-5AX for wide composite panels, wing skins and foam or modeling-board patterns, where 87.5 in (2,223 mm) of Y travel and fast rapids matter more than spindle power, and the US$399,995 list price leaves budget for tooling. Choose the VS-3-5AX for aerospace aluminum structures and tall molds that need 50 in (1,270 mm) of Z, a 29 hp spindle, 70+1 tools and a 10,000 lb load rating.
