Okuma MB-4000H vs Okuma MB-5000HII
Okuma vs Okuma · Horizontal Machining Centers
Summary
The Okuma MB-4000H and the Okuma MB-5000HII are two Okuma horizontal machining centers one pallet size apart. Okuma publishes few comparable figures for this pair, and the main one is pallet size: 400 × 400 mm (15.75 × 15.75 in) on the MB-4000H against 500 × 500 mm (19.69 × 19.69 in) on the MB-5000HII.
Rapid traverse is the same, 60,000 mm/min (2,362 ipm) against 60 m/min, and both list 48 tools as standard. The MB-4000H row also lists optional Multi-Magazine versions with 64, 110, 146, 182 and 218 tools; no magazine options appear for the MB-5000HII here.
Specifications Comparison
| Specification | Okuma MB-4000H | Okuma MB-5000HII |
|---|---|---|
| Pallet Size | 400 × 400 mm (15.75 × 15.75 in) | 500 × 500 mm (19.69 × 19.69 in) |
| Tool Capacity | 48 [64, 110, 146, 182, 218] Multi-Magazine | 48 |
| Rapid Traverse | 60,000 mm/min (2,362 ipm) | 60 m/min |
Advantages
Okuma MB-4000H
- Optional Multi-Magazine versions with 64, 110, 146, 182 and 218 tools listed, against 48 tools for the Okuma MB-5000HII
- A 400 × 400 mm (15.75 × 15.75 in) pallet format for small prismatic parts
Okuma MB-5000HII
- 500 × 500 mm (19.69 × 19.69 in) pallet against 400 × 400 mm (15.75 × 15.75 in)
- More pallet area for tombstone fixtures and housings at the same 60 m/min rapid traverse
Verdict
With so few published figures, the decision comes down to pallet size and tool count. Choose the Okuma MB-5000HII when housings, manifolds or tombstones need a 500 × 500 mm (19.69 × 19.69 in) pallet. Choose the Okuma MB-4000H when parts fit a 400 × 400 mm pallet, or when long unattended runs call for more than 48 tools, since its row lists Multi-Magazine options up to 218 tools. Rapid traverse does not separate them.
