DMG Mori CMX 50 U vs Haas GM-2-5AX
DMG Mori vs Haas Automation · 5-Axis Machining Centers
Summary
The DMG Mori CMX 50 U and the Haas GM-2-5AX are both 5-axis machines, but they serve different jobs. The CMX 50 U is a compact machine for small metal parts with 500 x 450 x 400 mm of travel; the GM-2-5AX is a large-format gimbal-head machine with 145 in (3,683 mm) of X travel and 87.5 in (2,223 mm) of Y, aimed at aerospace panels, composites and patterns.
The GM-2-5AX takes 6,000 lb (2,722 kg) on its table against 200 kg (440.9 lb), and its HSK-A63 spindle reaches 20,000 rpm against 12,000 RPM. The CMX 50 U is the heavier cutter: 22 kW (30 hp) against 16 hp (12 kW), 86 Nm (63 ft-lb) of torque against 11.3 ft-lbf @ 7,500 rpm, and 30 m/min (1,181 ipm) rapids against 472 ipm (12 m/min). Tool capacity is shared, 30 on the DMG Mori and 30+1 on the Haas.

Advantages
DMG Mori CMX 50 U
- 22 kW (30 hp) spindle against 16 hp (12 kW)
- 86 Nm (63 ft-lb) of torque against 15.3 N·m @ 7,500 rpm
- 30 m/min (1,181 ipm) rapids against 472 ipm (12 m/min)
- Choice of Fanuc 31i-B5 or Siemens 840D sl under CELOS
Haas GM-2-5AX
- 145 in (3,683 mm) x 87.5 in (2,223 mm) x 39.3 in (998 mm) of travel against 500 x 450 x 400 mm
- 6,000 lb (2,722 kg) table load against 200 kg (440.9 lb)
- 20,000 rpm HSK-A63 spindle against 12,000 RPM
Verdict
Choose by part size and material. The Haas GM-2-5AX is for large aerospace panels, composite trimming and drilling, aluminum profiling and foam or modeling-board patterns that need 145 in of X travel and a 6,000 lb table. The DMG Mori CMX 50 U is for small metal parts such as fittings, implants and mold components, where its 22 kW spindle and 86 Nm of torque matter more than reach.
