Overview

The Okuma V100R is a heavy-duty single-table vertical turning center designed for large-diameter chucking work on castings, forgings, and flanged components up to 1,050 mm (41.3 in) diameter. It is the big brother of the V40R, sharing the same box-guideway DNA and Thermo-Friendly architecture but scaled up significantly for parts that demand a larger swing and more spindle power.

The table spindle delivers 45/37 kW (60/50 hp) at a maximum speed of 800 RPM with 900 Nm (664 ft-lb) of torque. That torque rating handles deep roughing passes in large cast iron housings, steel pipe flanges, and alloy steel forgings without stalling. The table accepts chucks up to 24 inches (610 mm), and maximum workpiece weight is 1,000 kg (2,205 lb), covering the majority of large-diameter vertical turning applications in energy, oil and gas, and heavy equipment manufacturing.

X-axis travel is 560 mm (22.0 in) and Z-axis travel is 600 mm (23.6 in), giving ample room for deep boring and long-reach OD turning. The 12-station VDI 60 turret uses the largest standard VDI format for maximum tool rigidity on heavy cuts. Optional driven tools add cross-drilling, tapping, and face milling to reduce secondary operations. Rapid traverse is 20 m/min on both axes, using box guideways that prioritize vibration damping over speed.

Okuma's Thermo-Friendly Concept is critical on a machine this size, where thermal growth across the large casting can drift tolerances significantly during multi-hour rough-to-finish cycles. The OSP-P300L control with Collision Avoidance System protects the substantial tooling and workpiece investment during setup.

The V100R competes with the Doosan Puma VTS1620M, Hwacheon VT-1150R, and DMG Mori CTV 500. Pricing runs $400,000-$600,000 new. Machine weight is approximately 20,000 kg (44,092 lb). Floor space is 4,800 x 3,400 mm. The V100R is a specialist machine for shops that need to turn large-diameter parts in-house rather than outsourcing to a service center with a manual vertical boring mill.

Strengths & Limitations

Strengths

1,050 mm turning diameter with 1,000 kg workpiece capacity handles large castings and forgings that exceed the capacity of most standard vertical lathes
900 Nm spindle torque enables deep roughing passes in large-diameter cast iron and steel without stalling or vibration
VDI 60 turret provides the heaviest standard VDI tooling format for maximum rigidity on aggressive cuts at large diameters
Box guideways deliver superior vibration damping for interrupted cuts on rough castings, critical at this machine's diameter range
Thermo-Friendly Concept compensates for thermal growth across the large machine structure during multi-hour rough-to-finish cycles
20,000 kg machine weight provides the mass needed to dampen vibration when machining large, heavy workpieces

Limitations

800 RPM maximum table speed is limiting for smaller-diameter work; the machine is optimized for large parts where lower RPM is appropriate
20 m/min rapid traverse is slow compared to lighter machines, adding non-cutting time on jobs with many tool changes
20,000 kg weight and 4,800 x 3,400 mm floor space require significant foundation preparation and shop floor real estate
OSP control is Okuma-proprietary with no Fanuc or Siemens option, which matters for shops standardized on other control platforms
High capital cost limits the machine to shops with consistent large-diameter turning volume to justify the investment

Best For

Energy sector manufacturers turning large pipe flanges, valve bodies, and turbine components up to 1,050 mm diameter Oil and gas shops machining wellhead equipment, BOP components, and large-diameter alloy steel forgings Heavy equipment manufacturers producing sprockets, idler wheels, and bearing housings from castings weighing up to 1,000 kg Job shops replacing manual vertical boring mills with CNC automation for large-diameter turning work Shops needing to bring large-diameter turning in-house to control lead times and quality on critical components

Frequently Asked Questions

01 What does an Okuma V100R cost?

A new V100R typically runs $400,000-$600,000 depending on chuck size, driven tool options, and automation peripherals. The large machine size and heavy construction command a premium. Used machines are relatively rare due to long service life, but 2015-era units trade around $200,000-$350,000.

02 How does the V100R compare to the V40R?

The V100R is the larger version with 1,050 mm turning diameter vs 580 mm, 45/37 kW spindle power vs 30/22 kW, 900 Nm torque vs 500 Nm, and 1,000 kg workpiece capacity vs 300 kg. The V100R uses VDI 60 tooling vs VDI 50. The V40R is the right choice for parts under 580 mm where its smaller footprint and lower cost are advantages.

03 Can the V100R replace a manual vertical boring mill?

Yes, the V100R is the CNC equivalent of a manual VBM for parts up to 1,050 mm diameter. It offers dramatically faster cycle times, consistent accuracy via Thermo-Friendly Concept, and driven tool capability that eliminates secondary operations. Many shops buy a V100R specifically to replace aging manual VBMs.

04 What types of workpieces fit on the V100R?

The V100R handles disc-shaped, flanged, and ring-type components up to 1,050 mm diameter and 1,000 kg. Typical parts include pipe flanges, valve bodies, pump housings, turbine casings, large bearing races, gear blanks, sprockets, and heavy equipment hubs. Parts must be chuckable; shaft work requires a horizontal lathe.
