Machine Comparison
Okuma MA-8000H vs Okuma MB-10000H
Okuma vs Okuma · Horizontal Machining Centers
Summary
The Okuma MA-8000H and the Okuma MB-10000H are both No. 50 taper horizontal machining centers from Okuma, and both rapid at 50 m/min (1,969 ipm). The headline difference is pallet size: 800 × 800 mm (31.50 × 31.50 in) on the MA-8000H against 1,000 × 1,000 mm (39.37 × 39.37 in) on the MB-10000H.
The MA-8000H starts with the larger magazine, 60 tools as standard against 40, and lists optional magazines from 40 up to 400 tools. The MB-10000H lists 60 and 100–400 tool magazines as options. So the MB-10000H is stronger on workpiece size, and the MA-8000H on standard tool count.
Specifications Comparison
| Specification | Okuma MA-8000H | Okuma MB-10000H |
|---|---|---|
| Pallet Size | 800 × 800 mm (31.50 × 31.50 in) | 1,000 × 1,000 mm (39.37 × 39.37 in) |
| Spindle Taper / Nose | No. 50 | No. 50 |
| Tool Capacity | 60 [40, 81, 111, 141, 171, 195, 225, 255, 285, 320, 400] | 40 [60, 100–400] |
| Rapid Traverse | 50 m/min (1,969 ipm) | 50 m/min (1,969 ipm) |
Advantages
Okuma MA-8000H
- 60 tools as standard against 40 on the Okuma MB-10000H
- A smaller machine format for housings and frames that fit an 800 × 800 mm (31.50 × 31.50 in) pallet
Okuma MB-10000H
- 1,000 × 1,000 mm (39.37 × 39.37 in) pallet against 800 × 800 mm (31.50 × 31.50 in)
- Suited to large castings and weldments that need the bigger pallet
Verdict
Pick by pallet. Shops machining large castings and weldments that need a 1,000 × 1,000 mm (39.37 × 39.37 in) pallet should choose the Okuma MB-10000H, and plan for an optional magazine if 40 tools are too few. Shops whose housings and frames fit an 800 × 800 mm pallet are better served by the Okuma MA-8000H, which comes with 60 tools as standard. Spindle taper and rapid traverse are the same on both, so they do not decide the choice.
