Overview

The Okuma 2SP-V40 is a twin-spindle inverted vertical CNC lathe that brings simultaneous OP10/OP20 turning capability to medium-diameter disc parts up to 400 mm (15.7 in). It shares the proven twin-spindle architecture of the 2SP-V760EX but scales up the turning envelope for larger automotive and industrial components including brake rotors, flywheels, and gear blanks that exceed the 2SP-V760EX's 300 mm limit.

Each inverted spindle delivers 22/18.5 kW (30/25 hp) at up to 2,500 RPM with 350 Nm (258 ft-lb) of torque. The twin-spindle layout means spindle one picks up a raw blank and machines OP10 while spindle two simultaneously machines OP20 on the previous part. This parallel processing effectively doubles throughput compared to a single-spindle vertical lathe. Maximum turning height is 250 mm (9.8 in) per station.

Each station features a 12-station VDI 50 turret with optional driven tools for cross-drilling and tapping. X-axis travel is 260 mm (10.2 in) and Z-axis travel is 350 mm (13.8 in) per station, with rapid traverse at 30 m/min on both axes. The integrated gantry loader transfers parts between stations and handles loading/unloading from conveyors, creating a fully automated cell within a single machine footprint.

Okuma's Thermo-Friendly Concept compensates for thermal growth across both spindles simultaneously, maintaining part-to-part consistency through long production runs without operator intervention. The OSP-P300L control manages both spindles, both turrets, and the gantry loader from a unified interface with Collision Avoidance System protecting the complex twin-spindle configuration.

The 2SP-V40 competes with the Emag VL 4 DUO, Fuji CSD-400II, and twin-spindle configurations from Weisser and Scherer. Pricing runs $500,000-$700,000 new. Machine weight is approximately 14,000 kg (30,864 lb). The machine targets Tier 1 automotive suppliers and heavy equipment manufacturers running 150,000+ parts per year where the twin-spindle throughput advantage justifies the capital investment.

Strengths & Limitations

Strengths

Twin-spindle architecture machines OP10 and OP20 simultaneously, doubling throughput versus single-spindle vertical lathes for disc parts
400 mm turning diameter handles larger components like full-size brake rotors and flywheels that exceed the 2SP-V760EX capacity
Integrated gantry loader creates a fully automated production cell within a single machine footprint without external robotics
VDI 50 turrets provide heavy-duty rigidity at both stations for aggressive roughing in cast iron and steel
Thermo-Friendly Concept compensates for thermal growth across both spindles simultaneously for consistent part quality
Inverted spindle design with gravity-assisted chip evacuation keeps both cutting zones clean throughout production runs

Limitations

Capital cost of $500,000-$700,000 requires high annual volumes (150,000+ parts) to achieve acceptable ROI versus two single-spindle machines
Twin-spindle configuration is optimized for dedicated production and offers limited changeover flexibility for mixed-part job shop environments
OSP control is Okuma-proprietary; no Fanuc or Siemens option available for standardized control environments
14,000 kg weight and 4,600 mm length require substantial floor space and foundation preparation
2,500 RPM maximum spindle speed is appropriate for steel and cast iron but limits surface footage on aluminum parts

Best For

Tier 1 automotive suppliers producing brake rotors, flywheels, and gear blanks at 150,000+ parts per year Heavy equipment manufacturers turning medium-to-large disc parts in cast iron and steel with OP10/OP20 requirements Production lines consolidating two single-spindle vertical lathes into a single twin-spindle machine to save floor space and operators Facilities needing fully automated turning cells without the complexity and cost of external robot integration High-volume producers of flanged components, pulleys, and bearing housings up to 400 mm diameter

Frequently Asked Questions

01 What does an Okuma 2SP-V40 cost?

A new 2SP-V40 typically runs $500,000-$700,000 depending on driven tool packages, gantry loader configuration, and peripheral equipment. While the upfront cost is high, the twin-spindle throughput advantage provides strong ROI at volumes above 150,000 parts per year.

02 How does the 2SP-V40 compare to the 2SP-V760EX?

The 2SP-V40 has a larger 400 mm turning diameter versus 300 mm on the 2SP-V760EX, more powerful spindles (22 kW vs 18.5 kW), higher torque (350 Nm vs 250 Nm), and VDI 50 tooling versus VDI 40. The 2SP-V40 handles larger brake rotors, flywheels, and gear blanks that exceed the 2SP-V760EX's envelope.

03 Can the 2SP-V40 run different parts on each spindle?

The 2SP-V40 is designed for sequential OP10/OP20 on the same part, not for running two different part numbers simultaneously. Spindle one machines OP10 while spindle two machines OP20 on the previous part, creating a continuous production flow.

04 What automation is included with the 2SP-V40?

The integrated gantry loader comes standard and handles part loading from conveyors, transfer between OP10 and OP20 stations, and unloading of finished parts. The gantry is designed as part of the machine, not a bolt-on addition, which improves reliability and reduces the total cell footprint.
