Haas Automation vs Makino · 5-Axis Machining Centers
Summary
The Haas GM-2-5AX and the Makino a500iR are both 5-axis machining centers, but they sit in different size classes and serve different jobs. The GM-2-5AX is a large-format machine with 145 x 87.5 x 39.3 in (3,683 x 2,223 x 998 mm) of travel and a 6,000 lb (2,722 kg) load rating. The a500iR travels 900 x 750 x 800 mm and carries 400 kg (880 lb.).
The Haas leads on standard spindle speed, 20,000 rpm against 14,000 rpm, though the Makino offers 20,000 and 24,000 rpm spindles as options. The Makino leads on tool capacity, 90 tools as standard against 30+1, with 133, 218 or 311 tools as options, and on rapids, 60,000 mm/min (2,362 ipm) against 472 ipm (12 m/min).
