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 optional heavy-duty table. With 1,400 mm X-axis, 1,200 mm Y-axis, and 1,350 mm Z-axis travel, the MA-8000H provides a generous work envelope for large castings, fabrications, and multi-face parts in heavy industry, energy, and aerospace applications.

The standard No. 50 spindle runs at 6,000 RPM with 30 kW (40 hp) at 10-minute rating and 22 kW (30 hp) continuous, designed for steel-focused workpieces. Three optional spindle configurations extend the range: a 12,000 RPM high-speed variant at 45 kW handling both aluminum and steel, a 6,000 RPM high-torque version producing 1,071 Nm for difficult materials like Inconel and titanium, and a powerful 10,000 RPM spindle delivering 45 kW with 652 Nm torque and a milling capacity of 1,157 cm3/min in S45C steel.

Tool storage holds 60 tools standard. Machine dimensions are 3,960 x 8,178 x 3,442 mm. The machine runs on Okuma's OSP control with Thermo-Friendly Concept, Anti-Crash System, Process Navi, and Servo Navi. The MA-8000H competes with the Mazak HCN-8800, DMG Mori NHX 8000, and Makino A100e in the 800mm HMC class. Okuma's high-torque spindle option at 1,071 Nm gives it an edge for shops machining difficult aerospace and energy materials. New MA-8000H machines price in the $600,000 to $1,000,000 range.

Strengths & Limitations

Strengths

1,071 Nm high-torque spindle option handles Inconel, titanium, and hardened steel that would stall standard spindles, making this a true difficult-materials machine
3,000 kg optional pallet load supports heavy castings and tombstone setups that exceed the capacity of most 800mm-class competitors
Material removal rate of 1,157 cm³/min in S45C steel and 1,389 cm³/min in FCD450 cast iron demonstrates exceptional roughing productivity
1,400 x 1,200 x 1,350 mm work envelope with expanded travel over previous generations accommodates larger and more complex workpieces
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 particularly valuable on large HMCs where thermal growth proportional to machine size causes significant dimensional errors

Limitations

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

Best For

Aerospace manufacturers machining structural components in titanium and Inconel where the 1,071 Nm high-torque spindle is essential Energy sector shops machining large valve bodies, compressor housings, and turbine components in alloy steels Heavy equipment manufacturers producing large castings, gear housings, and structural components up to 3,000 kg Automotive manufacturers machining large engine blocks, cylinder heads, and transmission cases on 800mm pallets Shops consolidating multiple setups by machining all faces of large parts in a single horizontal machining center

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 depending on spindle selection, tool magazine configuration, and automation. The 10,000 RPM powerful spindle and multi-pallet automation systems are the biggest cost adders. Used MA-8000H machines from 2008-2018 trade between $200,000 and $500,000 depending on hours, spindle condition, and configuration.

02 Which spindle option should I choose?

Standard 6,000 RPM: budget option for general steel and cast iron. 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 capability. 6,000 RPM high-torque (1,071 Nm): dedicated difficult-materials spindle for Inconel, titanium, and hardened steel. Most versatile shops choose the 10,000 RPM powerful spindle.

03 How does the MA-8000H compare to the MA-12500H?

The MA-8000H uses 800mm pallets with ø1,450mm workpiece capacity, while the MA-12500H uses 1,250mm pallets for ø2,000mm parts. The MA-12500H has more spindle power (45 kW standard vs 30 kW) and larger tool magazine (81 vs 60). Choose the MA-8000H when your parts fit within the 800mm platform, and the MA-12500H when you need capacity for truly large workpieces.

04 What material removal rates can I expect?

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 that translate to fast material removal on large workpieces. Actual rates depend on tooling, cutting strategy, and fixture rigidity.

05 Can the MA-8000H run unattended?

Yes. The dual-pallet changer enables loading one pallet while cutting on the other. Tool life management and the Anti-Crash System support unattended operation. Multi-pallet automation systems are available for extended lights-out production. The 60-tool magazine covers most part programs, and expanded magazines are available for high-mix unattended work.
