Machine Comparison
Okuma MU-4000V vs Okuma MU-5000V
Okuma vs Okuma · 5-Axis Machining Centers
Summary
The Okuma MU-4000V and Okuma MU-5000V are both from Okuma's 5-axis machining centers lineup, making this a common upgrade or lineup decision for shops already invested in the Okuma ecosystem. The Okuma MU-4000V leads in max spindle speed (15,000 RPM (12,000 RPM in turning mode) vs 10,000 RPM (options: 6,000, 8,000, 15,000, 20,000, 25,000 RPM)). The Okuma MU-4000V leads in spindle power (22/18.5 kW (10 min/continuous) (30/25 hp) vs 11/7.5 kW (15/10 hp) [options: 15/11 kW, 22/18.5 kW]). These machines are closely matched across most specifications, making the decision more about specific feature priorities, dealer support, and your existing shop ecosystem than raw spec advantages. Both machines are proven performers in production environments and represent solid investments for shops in the market for a 5-axis machining center.

Advantages
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 spindle power at 22/18.5 kW (10 min/continuous) (30/25 hp) for aggressive material removal in harder materials
- More competitive pricing at $300,000 - $450,000 compared to $350,000 - $500,000+
Okuma MU-5000V
- Superior max table load at 500 kg (1,100 lb) vs 300 kg (661 lb)
- Backed by Okuma's dealer and service network for parts and support
- Aerospace job shops machining Inconel, titanium, and aluminum structural components requiring simultaneous 5-axis capability with heavy cutting loads
Verdict
This is a close matchup. The Okuma MU-4000V and Okuma MU-5000V trade advantages across different specifications, making neither a clear winner on paper alone. Your decision should come down to practical factors: which dealer is closer, which control system your operators already know, what tooling ecosystem you're invested in, and which machine's specific strengths match your highest-volume work. Get quotes on both, run test cuts with your actual parts if possible, and factor in long-term service and support costs.
