Advantages
Okuma MU-10000H
- More spindle power at 45/37 kW (20 min/continuous) (60/50 hp) for aggressive material removal in harder materials
- Superior spindle torque at 1,071 Nm standard; 1,920 Nm gear spindle option vs 199/146 Nm (5 min/continuous)
- Larger tool magazine with 81 tools capacity reduces manual tool changes on complex parts
- Superior max workpiece diameter at ø1,500 mm (59.1 in) vs ø500 mm (19.7 in)
- Superior max workpiece height at 1,175 mm (46.3 in) vs 400 mm (15.7 in)
Okuma MU-4000V
- Higher maximum spindle speed of 15,000 RPM (12,000 RPM in turning mode) enables faster cutting on aluminum and non-ferrous materials
- More competitive pricing at $300,000 - $450,000 compared to $1,500,000 - $2,500,000
- Backed by Okuma's dealer and service network for parts and support
- Aerospace shops machining small aluminum and titanium fittings, brackets, and structural components requiring simultaneous 5-axis contouring
Verdict
The Okuma MU-10000H holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the Okuma MU-10000H's strengths in areas like Spindle Power and Spindle Torque align with your work, it's the clear pick. The Okuma MU-4000V may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
