Machine Comparison
Makino a500iR vs Okuma GENOS M460V-5AX
Makino vs Okuma · 5-Axis Machining Centers
Summary
The Makino a500iR and the Okuma GENOS M460V-5AX are both 5-axis machining centers with 40-taper spindles, but the Makino is the larger machine. Its travels are 900 x 750 x 800 mm against 762 x 460 x 460 mm on the Okuma, and its standard magazine holds 90 tools against 48.
The Makino also moves faster, with rapid traverse of 60,000 mm/min (2,362 ipm) against 40 m/min in X and Y and 32 m/min in Z, and its magazine can be extended to 133, 218 or 311 tools as an option. The Okuma has the higher standard spindle speed, 15,000 rpm against 14,000 rpm. Makino offers 20,000 and 24,000 rpm spindles as extra-cost options, and those require HSK-A63 tooling.

Advantages
Makino a500iR
- Longer travels: 900 x 750 x 800 mm against 762 x 460 x 460 mm
- 90 tools standard against 48, with 133, 218 or 311 tools optional
- Rapid traverse of 60,000 mm/min (2,362 ipm) against 40 m/min in X and Y
- Optional 20,000 and 24,000 rpm spindles for structural aluminum work
Okuma GENOS M460V-5AX
- Higher standard spindle speed: 15,000 rpm against 14,000 rpm
- CAT 40 Big Plus spindle as listed, where the Makino's standard taper is CAT40
- Sized for compact multi-sided parts that do not need the Makino's larger envelope
Verdict
Choose the Makino a500iR for larger five-axis parts, structural aluminum and jobs with many tools: it has 900 x 750 x 800 mm of travel, 90 tools as standard and optional 20,000 and 24,000 rpm spindles. Choose the Okuma GENOS M460V-5AX for compact multi-sided parts that fit within 762 x 460 x 460 mm and need no more than 48 tools; its 15,000 rpm standard spindle is slightly faster than the Makino's 14,000 rpm.
