Overview

The Okuma MILLAC 1000VH is the largest machine in Okuma's MILLAC VH series, a heavy-duty 5-axis vertical machining center with a 1,000 mm (39.4 in) rotary table designed for the biggest parts that shops need to machine in five axes. If the 800VH isn't big enough, this is where Okuma goes next before stepping into full horizontal boring mill territory.

Travel measures 1,500 x 1,300 x 700 mm (59.1 x 51.2 x 27.6 in) on the linear axes, providing an enormous work envelope. The B-axis tilts from +10 to -110 degrees, and the C-axis rotates 360 degrees continuously. The 1,000 mm diameter rotary table supports loads up to 1,500 kg (3,307 lb), handling large aerospace structural castings, energy sector components, and heavy industrial parts.

The spindle runs at 10,000 RPM with 30/22 kW (40/30 hp) through a No. 50 (BT 50) taper. The higher power rating compared to the 800VH reflects the larger parts and heavier cuts this machine is designed for. The standard ATC holds 40 tools with options to 60, 80, or 120 positions. Rapid traverse hits 36 m/min (1,417 ipm) on X, 40 m/min (1,575 ipm) on Y, and 36 m/min (1,417 ipm) on Z.

Machine weight is approximately 28,000 kg (61,729 lb), requiring serious foundation engineering. The double-column construction with wide column spacing accommodates the massive rotary table while maintaining structural rigidity across the full travel range. Floor space runs approximately 5,800 x 5,000 mm (228 x 197 in), making this a machine that needs a dedicated bay in the shop.

The OSP-P500 control is standard with Collision Avoidance System, Thermo-Friendly Concept, and 5-Axis Auto Tuning. On a machine this large, thermal management across the structure is critical, and Okuma's thermal compensation is one of the key reasons shops choose the MILLAC over competitors. The CAS system becomes essentially mandatory when workpieces alone can cost more than the machine.

New pricing typically ranges from $700,000-$950,000 depending on configuration. The MILLAC 1000VH competes with machines like the DMG Mori DMU 125 P duoBLOCK, Mazak VARIAXIS i-1050, and the Hermle C 62 U for large-envelope 5-axis vertical machining.

Strengths & Limitations

Strengths

1,000 mm rotary table with 1,500 kg load capacity handles the largest parts in the MILLAC VH lineup, supporting heavy castings, forgings, and weldments
1,500 x 1,300 x 700 mm travel envelope is among the largest available in a 5-axis vertical configuration, reducing the need for repositioning on oversize parts
30 kW (40 hp) No. 50 taper spindle delivers the power and tool clamping force for aggressive material removal on large steel, titanium, and Inconel components
28,000 kg machine mass with double-column construction provides maximum vibration damping, critical for maintaining surface finish quality on large simultaneous 5-axis toolpaths
Thermo-Friendly Concept manages thermal drift across the large machine structure during cycle times that can extend to 8-12 hours on complex aerospace parts
Tool magazine options up to 120 positions accommodate the extensive tool inventories needed for complex large-part machining without mid-cycle tool loading

Limitations

5,800 x 5,000 mm footprint requires a dedicated machine bay and clear overhead for crane access, consuming significant shop floor real estate
28,000 kg weight demands engineered foundation work with reinforced concrete, adding $20,000-$40,000 to installation costs
Starting price of $700,000 limits the buyer pool to shops with consistent large-part work that justifies the capital investment
10,000 RPM spindle speed cap means shops doing high-speed aluminum finishing may need to look at high-RPM spindle options at additional cost
Machine size creates lengthy warm-up periods in shops without climate control, though Thermo-Friendly Concept mitigates thermal drift once the machine stabilizes

Best For

Aerospace manufacturers machining large structural components, wing spars, bulkheads, and landing gear housings that exceed 800 mm part envelopes Energy sector shops producing large turbine casings, generator components, and nuclear industry parts requiring 5-axis access on heavy workpieces Die and mold builders working on the largest automotive stamping dies and injection molds requiring 5-axis machined surfaces Defense contractors machining large vehicle hull components, weapon system housings, and structural armor plates with complex multi-face features Heavy equipment manufacturers producing large hydraulic valve blocks, pump housings, and gearbox cases with features on multiple faces Shipbuilding and marine equipment manufacturers machining propulsion components, reduction gear housings, and large valve assemblies

Frequently Asked Questions

01 What does an Okuma MILLAC 1000VH cost?

New pricing ranges from $700,000-$950,000 depending on spindle options, tool magazine capacity (40-120), probing, coolant systems, and automation integration. Foundation preparation typically adds $20,000-$40,000. Used MILLAC 1000VH machines are rare due to low production volumes and strong demand for large 5-axis capacity.

02 How does the MILLAC 1000VH compare to the 800VH?

The 1000VH offers a 1,000 mm table (vs 800 mm), 1,500 kg load capacity (vs 1,000 kg), more travel in all three axes, and a more powerful 30 kW spindle (vs 22 kW). It's substantially heavier at 28,000 kg vs 20,000 kg. Choose the 1000VH when your parts consistently exceed the 800VH's work envelope or table load capacity.

03 What foundation does the MILLAC 1000VH require?

At 28,000 kg, the machine requires a purpose-built reinforced concrete foundation. Okuma provides detailed foundation drawings specifying slab thickness (typically 400-500 mm), rebar specifications, and point load requirements at each leveling pad. Consult a structural engineer before installation. The foundation should be poured and cured well before the machine delivery date.

04 How does the MILLAC 1000VH compare to the DMG Mori DMU 125 P duoBLOCK?

Both are large 5-axis vertical machines targeting similar applications. The DMG Mori duoBLOCK architecture offers excellent static and dynamic rigidity. The Okuma counters with Thermo-Friendly Concept for thermal management and CAS for collision avoidance. The DMG Mori offers Siemens or Heidenhain control options. Service network strength varies by region, with Okuma generally strong in North America and DMG Mori strong globally.

05 Can this machine be automated?

Yes. The MILLAC 1000VH can be equipped with pallet changers for multiple workpiece setups, and the large tool magazine options (up to 120 tools) support extended unattended operation. Robotic loading is possible with appropriately sized robots for the heavy workpieces this machine handles. The CAS system provides an additional safety layer for lights-out operation.
