Overview

The Okuma MB-80V DC is Okuma's largest box-way vertical machining center, featuring a 1,600 x 800 mm table with 1,600 mm of X-axis travel, 1,050 mm Y-axis travel, and a 600 mm maximum workpiece height capacity. The DC (Double Column) variant adds the rigidity of a bridge-style construction to the proven MB platform, making it a go-to machine for heavy steel and cast iron work where accuracy under load matters more than spindle speed.

Three spindle options cover different application requirements. The standard broad-range No. 40 spindle runs 15,000 RPM producing 26 kW (35 hp) at 10-minute rating and 18.5 kW (25 hp) continuous with 199 Nm of torque. The high-speed No. 40 special spindle reaches 20,000 RPM at 30 kW (40 hp). The heavy-duty No. 40/50 special spindle runs 12,000 RPM with 33 kW (44 hp) at 10% ED and 26 kW (35 hp) continuous, delivering 302 Nm of torque for aggressive roughing in hard materials.

The table supports workpieces up to 2,500 kg, providing capacity for heavy castings and steel weldments. Tool storage holds 32 tools standard. Machine dimensions are 4,500 x 2,970 x 3,320 mm. The MB-80V DC runs on Okuma's OSP control with Thermo-Friendly Concept, Anti-Crash System, and the full suite of Okuma intelligent technologies.

The MB-80V DC competes with the Mazak VTC-800/30SR, DMG Mori DMC 1450 V, and Doosan DNM 750L II in the large VMC segment. Okuma's dual-column construction on the MB platform provides superior rigidity compared to C-frame competitors at this size. New MB-80V DC machines price in the $250,000 to $400,000 range depending on spindle selection and options. Specs sourced from Okuma Corporation published data.

Strengths & Limitations

Strengths

Double-column construction provides significantly higher rigidity than C-frame VMCs at this size, reducing chatter and improving accuracy under heavy cutting loads
2,500 kg table load capacity handles heavy castings and steel weldments that would overload most vertical machining centers in this class
Three spindle options from 12,000 to 20,000 RPM let shops configure for heavy roughing (302 Nm), general purpose, or high-speed finishing applications
1,600 mm X-axis travel with 1,600 x 800 mm table covers large workpieces without stepping up to a bridge mill
1,620 mm front door opening provides excellent crane access for loading heavy workpieces
Thermo-Friendly Concept and full Okuma intelligent technology suite come standard, not as expensive options

Limitations

32-tool magazine is relatively small for a machine of this size — shops running complex multi-operation programs will need to manage tool counts carefully
Heavy-duty No. 50 spindle option limits maximum speed to 12,000 RPM, which constrains surface speed capability on aluminum
Machine weight and footprint require solid foundation preparation, adding installation cost beyond the machine purchase price
Price premium over competing C-frame VMCs of similar travel may not be justified for shops cutting primarily aluminum or light materials

Best For

Job shops machining heavy steel and cast iron parts requiring the rigidity of a double-column design without the cost of a bridge mill Mold base manufacturers machining large mold frames up to 2,500 kg requiring consistent accuracy across the full table Energy sector shops machining valve bodies, pump housings, and turbine components in steel and alloy materials Aerospace shops machining aluminum structural components that benefit from the rigid double-column structure for chatter-free finishing General machining operations requiring a large-table VMC with high load capacity and multiple spindle configuration options

Frequently Asked Questions

01 What does a new Okuma MB-80V DC cost?

New MB-80V DC machines typically price between $250,000 and $400,000 depending on spindle selection and options. The heavy-duty No. 50 spindle and expanded tool magazines add to the base price. Used MB-80V machines from 2012-2020 trade between $100,000 and $200,000 depending on hours, spindle condition, and configuration.

02 Which spindle should I choose for the MB-80V DC?

The standard 15,000 RPM No. 40 spindle covers most general-purpose work across steel, aluminum, and cast iron. For shops primarily roughing steel and cast iron, the 12,000 RPM heavy-duty spindle with 302 Nm torque is the better choice. For aluminum-focused shops or high-speed finishing, the 20,000 RPM option provides the surface speeds needed. Most job shops running mixed materials choose the standard 15,000 RPM as the best all-around option.

03 How does the MB-80V DC compare to the standard MB-80V?

The DC (Double Column) variant adds a bridge-style upper structure for significantly improved rigidity compared to the standard C-frame MB-80V. This makes a noticeable difference in surface finish and accuracy when cutting heavy materials under load. The trade-off is slightly higher cost and more limited Y-axis accessibility from the sides. Choose the DC variant for heavy cutting in steel and cast iron, and the standard for lighter materials where access flexibility matters more.

04 Can the MB-80V DC handle 5-axis work?

The MB-80V DC is a 3-axis machine. For 5-axis capability on this platform, shops typically add a rotary trunnion table from companies like Tsudakoma or Kitagawa. However, the workpiece size that fits within the trunnion is significantly smaller than the full table capacity. For dedicated 5-axis work, Okuma's MU-V series is a better fit. The MB-80V DC excels at heavy 3-axis and 3+2 work.
