Machine Comparison
Okuma MA-600HII vs Okuma MA-600HIII
Okuma vs Okuma · Horizontal Machining Centers
Summary
The Okuma MA-600HII and the Okuma MA-600HIII are, as the names indicate, two generations of the same horizontal machining center, and the table shows how little the frame changed. Both carry a 630 × 630 mm pallet, 900 mm (35.4 in) of Y travel, 1,000 mm (39.4 in) of Z travel, 60 tools as standard and 60 m/min (2,362 ipm) rapids.
The differences are small. The Okuma MA-600HIII has 1,050 mm (41.3 in) of X travel against 1,000 mm (39.4 in), and its optional magazines run up to 400 tools against up to 194 on the Okuma MA-600HII. Spindle power is a tie at 30 kW (40 hp): the Okuma MA-600HIII is listed at 30/22 kW (40/30 hp), and the table notes higher power options for the Okuma MA-600HII.
Specifications Comparison
| Specification | Okuma MA-600HII | Okuma MA-600HIII |

| Y-Axis Travel | 900 mm (35.4 in) | 900 mm (35.4 in) |
| Z-Axis Travel | 1,000 mm (39.4 in) | 1,000 mm (39.4 in) |
| Pallet Size | 630 x 630 mm (24.8 x 24.8 in) | 630 × 630 mm (24.80 × 24.80 in) |
| Spindle Power | 30 kW (40 hp); higher power options available | 30/22 kW (40/30 hp) |
| Tool Capacity | 60 tools standard (up to 194 optional) | 60 [40, 81, 111, 141, 171, 195, 225, 255, 285, 320, 400] |
| Rapid Traverse | 60 m/min (2,362 ipm) | 60 m/min (2,362 ipm) |
Advantages
Okuma MA-600HII
- Same 630 x 630 mm (24.8 x 24.8 in) pallet, 900 mm (35.4 in) of Y and 1,000 mm (39.4 in) of Z as the later machine
- 30 kW (40 hp) spindle, with higher power options noted in the table
- Suited to heavy milling and boring of castings and weldments
Okuma MA-600HIII
- 1,050 mm (41.3 in) of X travel against 1,000 mm (39.4 in)
- Optional magazines up to 400 tools against up to 194
- Suited to cells that need large tool counts for tombstone and multi-face work
Verdict
Shops that need the extra X travel or the largest tool count should choose the Okuma MA-600HIII: 1,050 mm against 1,000 mm, and optional magazines up to 400 tools. On every other row the table shows the same machine, with the same 630 × 630 mm pallet, the same Y and Z travel, 60 m/min (2,362 ipm) rapids and a 30 kW (40 hp) rating. A shop whose parts and tool lists fit the Okuma MA-600HII gains little on these figures from the Okuma MA-600HIII.
