Makino a500iR vs Makino V90S
Makino vs Makino · 5-Axis Machining Centers
Summary
The Makino a500iR and the Makino V90S are both Makino five-axis machines, but they come from different size classes and serve different jobs. The a500iR is a production machine for parts up to 400 kg (880 lb.); the V90S is a large die and mold machine with 2,000 mm (78.7 in) of X travel, 1,300 mm (51.2 in) of Y and a 5,000 kg (11,023 lb) table load. Both have 800 mm (31.5 in) of Z travel.
The V90S runs a 20,000 rpm HSK-A63 spindle, against 14,000 rpm standard on the a500iR, which offers 20,000 and 24,000 rpm options. The a500iR is the faster production machine: 1.0 sec tool-to-tool against 8 sec, 90 tools standard against 40 (120 optional), and 60,000 mm/min rapids against 58,000 mm/min.

Advantages
Makino a500iR
- 1.0 sec tool-to-tool change against 8 sec
- 90 tools standard against 40
- 60,000 mm/min (2,362 ipm) rapid traverse against 58,000 mm/min (2,283 in/min)
- Optional 24,000 rpm spindle for structural aluminum
Makino V90S
- 2,000 mm X and 1,300 mm Y travel against 900 mm and 750 mm
- 5,000 kg (11,023 lb) table load against 400 kg
- 20,000 rpm spindle against 14,000 rpm standard on the a500iR
Verdict
These machines answer different jobs. Choose the Makino V90S for long dies and molds up to 2,000 mm in X and up to 5,000 kg, where contour finishing at 20,000 rpm matters more than tool-change time. Choose the Makino a500iR for five-axis production parts up to 400 kg, where a 1.0 sec tool change, 90 tools and 60,000 mm/min rapids keep cycle times short.
