Okuma MB-10000H vs Okuma MB-4000H
Okuma vs Okuma · Horizontal Machining Centers
Summary
The Okuma MB-10000H and the Okuma MB-4000H are both Okuma horizontal machining centers, but they serve different jobs. The MB-10000H is a No. 50 taper machine with a 1,000 × 1,000 mm (39.37 × 39.37 in) pallet. The MB-4000H is a No. 40 (BT40) machine with a 400 × 400 mm (15.75 × 15.75 in) pallet.
The MB-10000H is stronger on workpiece size and spindle taper. The MB-4000H is faster, with 60,000 mm/min (2,362 ipm) rapids against 50 m/min (1,969 ipm), and it starts with 48 tools against 40. Both list larger magazines as options: 60 or 100–400 tools on the MB-10000H, and Multi-Magazine versions from 64 up to 218 tools on the MB-4000H.

Advantages
Okuma MB-10000H
- 1,000 × 1,000 mm (39.37 × 39.37 in) pallet against 400 × 400 mm (15.75 × 15.75 in)
- No. 50 spindle taper for heavy milling and boring, against No. 40 (BT40)
- Optional magazines of 100–400 tools, against a largest listed option of 218 tools
Okuma MB-4000H
- 60,000 mm/min (2,362 ipm) rapid traverse against 50 m/min (1,969 ipm)
- 48 tools as standard against 40
- A 400 × 400 mm pallet format for small prismatic parts and tombstone work
Verdict
These machines are not alternatives for the same part. Choose the Okuma MB-10000H for large castings and weldments in iron and steel that need a 1,000 × 1,000 mm pallet and a No. 50 taper. Choose the Okuma MB-4000H for short-cycle production of small prismatic parts, particularly in aluminum, where a 400 × 400 mm pallet is enough and 60,000 mm/min (2,362 ipm) rapids cut non-cutting time.
