Advantages
DMG Mori DMU 50 3rd Generation
- 650 mm (25.6 in) X travel against 560 mm (22.0 in)
- 15,000 rpm standard spindle against 14,000 rpm
- Built for 5-axis simultaneous work rather than horizontal production
Makino a51nx
- 640 mm (25.2 in) Y and Z travel against 520 mm (20.5 in) and 475 mm (18.7 in)
- 400 kg (880 lb) load against 300 kg (661.4 lb)

Verdict
Choose by part type. The DMG Mori DMU 50 3rd Generation fits 5-axis simultaneous work on contoured parts and fixtures within 300 kg (661.4 lb), with the optional 20,000 rpm spindle for small-tool finishing. The Makino a51nx fits high-volume production of small prismatic parts on tombstone fixtures, with many short drilling and tapping operations, where its 400 kg (880 lb) load and 60-tool standard magazine serve a whole part family.
