Overview
The Okuma MB-10000H is a large-scale horizontal machining center built on Okuma's box-way platform with 1,000 x 1,000 mm pallets for machining heavy workpieces up to 1,400 mm diameter by 1,450 mm height. The MB-10000H brings the rigidity and vibration damping advantages of box-way construction to the large HMC class, where most competitors have moved to linear guides for faster positioning.
The No. 50 spindle runs at 6,000 RPM with 30 kW (40 hp) at 10-minute rating and 22 kW (30 hp) continuous. This power level is well-matched for heavy turning and milling operations in steel, cast iron, and alloy materials typical of the workpieces that fit on 1,000 mm pallets. Tool storage holds 40 tools standard. Machine dimensions are 4,545 x 6,465 x 3,410 mm.
The box-way design on a machine of this scale provides significant vibration damping advantages for heavy roughing operations where cutting forces can excite structural resonances in lighter linear-guide machines. This translates to better surface finish, longer tool life, and the ability to take more aggressive cuts without chatter. The MB-10000H runs on Okuma's OSP control with the full suite of intelligent technologies.
The MB-10000H competes with the Mazak HCN-8800, DMG Mori NHX 10000, and Toyoda FH1250SX in the large HMC segment. Within Okuma's lineup, it complements the MA-12500H by offering box-way rigidity at the 1,000 mm pallet size versus the MA-12500H's larger envelope. New MB-10000H machines price in the $700,000 to $1,100,000 range. The machine is ideal for heavy industry, energy, and defense applications where workpiece weight and rigidity demands favor box-way construction. Specs sourced from Okuma Corporation published data.

Strengths & Limitations
Strengths
- Box-way construction on all axes provides superior vibration damping for heavy roughing on large steel and cast iron workpieces
- 1,000 x 1,000 mm pallets with ø1,400 x 1,450 mm workpiece capacity covers large parts without stepping up to the 1,250mm-class MA-12500H
- Box-way rigidity enables more aggressive cutting parameters and deeper cuts without chatter, improving material removal rates in practice
- No. 50 spindle with 30 kW power is well-matched for the heavy ferrous material work typical at this machine scale
- Thermo-Friendly Concept maintains accuracy on large machine structures where thermal effects are proportionally significant
- Dual pallet changer provides productivity advantages for heavy-part production where workpiece loading time is substantial
Limitations
- 40-tool magazine is relatively limited for a machine of this size and cost — complex parts may require tool management between operations
- 6,000 RPM maximum spindle speed restricts surface speed capability, particularly for any aluminum work or high-speed finishing
- Box-way construction means slower rapid traverse compared to linear-guide competitors, adding non-cutting time on large parts with many positioning moves
- Machine footprint of 4,545 x 6,465 mm requires significant dedicated floor space with adequate overhead crane capacity
- 30 kW spindle power is moderate for the 1,000mm pallet class — the MA-8000H and MA-12500H offer higher power options

Frequently Asked Questions
01
New MB-10000H machines typically price between $700,000 and $1,100,000 depending on options and automation configuration. Expanded tool magazines, high-pressure coolant, and multi-pallet automation add to the base price. Used MB-10000H machines are uncommon but trade in the $300,000-$600,000 range when available.
02
At the 1,000mm pallet scale, cutting forces are substantial and workpieces are heavy. Box ways damp vibrations more effectively than linear guides under these conditions, producing better surface finish and allowing more aggressive cutting parameters without chatter. The speed disadvantage of box ways matters less on large parts where cutting time dominates over positioning time.
03
The MB-10000H has larger 1,000mm pallets (vs 800mm) with box-way construction but fewer spindle options (6K RPM only) and less spindle power (30 kW vs up to 45 kW). The MA-8000H offers more versatility with 4 spindle options and higher power. Choose the MB-10000H for larger workpieces requiring box-way rigidity. Choose the MA-8000H for smaller-to-medium workpieces needing spindle versatility.
04
For straightforward large-part operations (roughing, semi-finishing, finishing with standard tools), 40 tools is typically adequate. For complex multi-face operations requiring many different tool types, 40 tools can be limiting. Evaluate your typical part programs and tool requirements before committing. The MA-series machines offer larger magazine options if tool count is a concern.
