Overview

The Okuma MA-8000H is a large-platform horizontal machining center built around 800 x 800 mm pallets for machining substantial workpieces up to 1,450 mm diameter by 1,450 mm height with loads up to 3,000 kg on the heavy-duty table option. Using linear guide construction for maximum axis speed combined with a suite of powerful spindle options, the MA-8000H targets manufacturers in aerospace, heavy equipment, energy, and large automotive production where a combination of work envelope, spindle power, and cycle-time efficiency drives machine selection.

Axis travels are 1,400 mm on X, 1,200 mm on Y, and 1,350 mm on Z — a generous envelope for large castings, fabrications, and multi-face parts. The standard No. 50 spindle runs at 6,000 RPM with 30 kW at 10-minute rating. Four spindle configurations are available to match different production requirements: standard 6,000 RPM for general steel work; 12,000 RPM high-speed at 45 kW for aluminum and mixed-material production; 6,000 RPM high-torque at 1,071 Nm for difficult materials including Inconel and titanium; and a powerful 10,000 RPM option at 45 kW with 652 Nm torque delivering 1,157 cm³/min material removal in S45C steel.

Tool storage holds 60 tools standard. Machine dimensions are 3,960 x 8,178 x 3,442 mm. The MA-8000H runs on Okuma's OSP-P500M control with Thermo-Friendly Concept, Anti-Crash System, Process Navi, and Servo Navi — the same intelligent machining suite across Okuma's large-HMC line. Dual pallet changer is standard for continuous production.

The MA-8000H competes with the Mazak HCN-8800, DMG Mori NHX 8000, and Makino A100e in the 800 mm HMC class. Okuma's high-torque spindle option at 1,071 Nm gives it a particular edge for shops machining difficult aerospace and energy materials. The 10,000 RPM powerful spindle with 1,157 cm³/min steel removal rate makes it highly competitive for high-volume production. New MA-8000H machines price $600,000–$1,000,000.

Strengths & Limitations

Strengths

1,071 Nm high-torque spindle option handles Inconel, titanium, and hardened steel that would stall standard spindles — a true difficult-materials specification
3,000 kg optional pallet load supports heavy castings and tombstone setups that exceed the capacity of most 800 mm-class competitors
Material removal of 1,157 cm³/min in S45C steel and 1,389 cm³/min in FCD450 demonstrates exceptional roughing productivity
1,400 x 1,200 x 1,350 mm work envelope accommodates large and complex workpieces across heavy industry applications
Four spindle options from standard 6K to high-torque 1,071 Nm let shops configure precisely for their material and application mix
Thermo-Friendly Concept is especially valuable on large HMCs where thermal growth proportional to machine size causes significant dimensional errors

Limitations

6,000 RPM standard spindle limits versatility; most shops will need to specify the 10K or 12K RPM option for mixed-material work
Machine footprint of 3,960 x 8,178 mm plus service clearances requires substantial dedicated floor space and foundation preparation
60-tool standard magazine may be limiting for complex multi-operation programs on large parts — expanded options add cost
Premium pricing starting at $600,000 requires consistent large-part production volume to justify over smaller 630 mm-class alternatives

Best For

Frequently Asked Questions

01 What does a new Okuma MA-8000H cost?

New MA-8000H machines typically price between $600,000 and $1,000,000. The 10,000 RPM powerful spindle and multi-pallet automation systems are the largest cost adders above the base configuration. Used MA-8000H machines from 2008–2018 trade between $200,000 and $500,000 depending on hours, spindle condition, and options.

02 Which spindle option should I choose for the MA-8000H?

Standard 6,000 RPM: general steel and cast iron only. 10,000 RPM powerful (45 kW, 652 Nm): best all-around for mixed materials with strong roughing capability. 12,000 RPM high-speed (45 kW): for shops needing both steel and aluminum versatility. 6,000 RPM high-torque (1,071 Nm): dedicated difficult-materials spindle for Inconel, titanium, and hardened steels. Most versatile production shops choose the 10,000 RPM powerful spindle.

03 How does the MA-8000H compare to the MB-8000H?

The MA-8000H uses linear guides for higher axis speed and acceleration, while the MB-8000H uses box ways for maximum rigidity and vibration damping. The MA-8000H has more travel (1,400/1,200/1,350 mm vs slightly less on the MB) and a higher pallet load rating (3,000 kg vs 2,500 kg). Choose the MA-8000H for the high-torque spindle option and maximum work envelope; choose the MB-8000H when surface finish on steel under heavy cuts is the priority.

04 What material removal rates can I expect from the MA-8000H?

With the powerful 10,000 RPM spindle, the MA-8000H achieves 1,157 cm³/min in S45C medium carbon steel and 1,389 cm³/min in FCD450 ductile cast iron. These are aggressive roughing rates appropriate for large workpieces with significant stock removal. Actual rates depend on tooling selection, cutting strategy, and fixture rigidity.

05 Can the MA-8000H be integrated with extended automation?

Yes. Beyond the standard dual pallet changer, multi-pallet pool systems with dozens of pallets can be connected for lights-out production. Robot tending, pallet storage systems, and fixture automation are all compatible with the MA-8000H platform. Okuma's cell controller software manages job scheduling, tool life monitoring, and machine utilization reporting across multi-pallet installations.
