Overview
The Okuma MU-10000H is a large-scale 5-axis horizontal machining center designed for machining complex, heavy workpieces that require simultaneous 5-axis contouring in a horizontal orientation. With 1,550 mm X-axis, 1,600 mm Y-axis, and 1,650 mm Z-axis travel on 1,000 x 1,000 mm pallets, the MU-10000H provides one of the largest 5-axis work envelopes in the horizontal machining center class.
The trunnion table handles workpieces up to 1,500 mm diameter and 1,175 mm height at a maximum load of 2,500 kg. The A-axis tilts from +35 to -115 degrees while the B-axis rotates a full 360 degrees, providing comprehensive 5-axis access to large parts. The standard No. 50 spindle delivers 45 kW (60 hp) at 20-minute rating and 37 kW (50 hp) continuous at 6,000 RPM with 1,071 Nm maximum torque. An optional gear spindle pushes torque to 1,920 Nm for the most demanding materials.
Tool storage accommodates 81 tools. Machine dimensions are 6,880 x 10,930 x 3,694 mm. The machine runs on Okuma's OSP control with Thermo-Friendly Concept, Anti-Crash System, Five-Tuning, Process Navi, and Servo Navi. The horizontal orientation provides superior chip evacuation and gravity-assisted fixture loading compared to vertical 5-axis alternatives.
The MU-10000H competes with the Mazak INTEGREX e-1060V, DMG Mori DMU 200 P, and Starrag STC 1000 in the large 5-axis segment. Okuma's combination of 1,071-1,920 Nm spindle torque and full 5-axis capability on a horizontal platform with pallet changing makes it unique in this class. New MU-10000H machines typically price in the $1,500,000 to $2,500,000 range. The machine is purpose-built for large aerospace structural components, turbine blisks, landing gear assemblies, and heavy defense parts. Specs sourced from Okuma Corporation published data.

Strengths & Limitations
Strengths
- 1,071 Nm standard spindle torque with optional 1,920 Nm gear spindle handles the most demanding materials including Inconel, titanium, and hardened steel on large parts
- 1,550 x 1,600 x 1,650 mm travel envelope with 5-axis capability covers large structural components that most 5-axis machines cannot accommodate
- 2,500 kg workpiece capacity on the trunnion table handles heavy aerospace, defense, and energy sector parts
- Horizontal orientation provides superior chip evacuation and natural gravity-assisted fixture loading compared to vertical 5-axis alternatives
- 81-tool magazine provides deep tool capacity for complex multi-operation machining on large 5-axis parts
- Pallet-changing capability on a 5-axis horizontal platform enables dual-workpiece operation for improved spindle utilization on large parts
- Five-Tuning calibration system maintains 5-axis accuracy on the large trunnion table where geometric errors compound across the work envelope
Limitations
- 6,000 RPM maximum spindle speed limits surface speed capability, particularly for aluminum finishing on large-diameter parts
- Machine footprint of 6,880 x 10,930 mm requires a dedicated large bay with substantial overhead crane capacity
- Premium pricing starting at $1,500,000 limits this machine to shops with consistent large-part 5-axis production volume
- Foundation requirements and rigging for a machine of this scale add significant installation costs
- A-axis range of +35° to -115° may be limiting for some 5-axis access patterns compared to wider-range trunnion designs

Frequently Asked Questions
01
New MU-10000H machines typically price between $1,500,000 and $2,500,000 depending on spindle configuration (standard vs gear spindle), tool magazine size, and automation options. Installation including foundation, rigging, and electrical can add $200,000-$500,000. Used MU-10000H machines are rare on the secondary market due to the specialized nature of applications.
02
The 1,920 Nm gear spindle is for shops primarily machining Inconel, titanium, and high-strength alloys where the standard 1,071 Nm is insufficient for target material removal rates. The gear spindle adds cost and complexity (gear maintenance, potential gear noise). Most aerospace shops machining titanium find the 1,071 Nm standard spindle adequate. The gear spindle is specifically for the most demanding roughing applications in difficult materials.
03
The horizontal orientation provides better chip evacuation (gravity pulls chips away from the workpiece), easier fixture loading with overhead cranes, and better access to the underside of complex parts. The trade-off is larger footprint and potentially more complex fixture design. For large aerospace and energy parts, the horizontal orientation is generally preferred for chip management and workpiece access.
04
The A-axis range of +35° to -115° provides 150° of total tilt. This covers most 5-axis machining scenarios but may require workpiece re-positioning for some geometries that need full +/-90° or greater tilt range. The -115° negative tilt provides good undercut access. Evaluate your specific part geometries against this range before specifying the machine.
05
The dual-pallet system enables basic unattended operation — one pallet cuts while the operator loads the other. With 81 tools, tool life management, and the Anti-Crash System, extended unattended cycles are practical. However, given the high-value nature of the parts this machine typically processes (often $10,000-$100,000+ per part), most shops prefer having an operator available to monitor the process.
