Advantages
Okuma MA-600HII
- Backed by Okuma's dealer and service network for parts and support
- Heavy steel and cast iron production where CAT 50 torque and box-way rigidity are non-negotiable for achieving required metal removal rates
Okuma MA-600HIII
- Greater x travel of 1,050 mm (41.3 in) accommodates larger workpieces
- More competitive pricing at $400,000 - $650,000 compared to $450,000 - $650,000
- Backed by Okuma's dealer and service network for parts and support
- Aerospace shops machining structural components in titanium and Inconel where the 1,071 Nm high-torque spindle handles difficult materials
Verdict
This is a close matchup. The Okuma MA-600HII and Okuma MA-600HIII 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.
