Okuma 2SP-2500H vs Okuma 2SP-V40
Okuma vs Okuma · CNC Lathes
Summary
The Okuma 2SP-2500H and the Okuma 2SP-V40 are two-spindle lathes for disc, flange and ring parts of about the same diameter: 410 mm (16.14 in) against 400 mm (15.75 in). The Okuma 2SP-V40 holds the work on a vertical spindle, and the two machines differ most in part length, spindle speed and spindle power.
The Okuma 2SP-V40 takes longer parts, with 450 mm (17.72 in) of turning length against 200 mm (7.87 in), and has the stronger spindle at 22/18.5 kW (30/25 hp) against 15/11 kW (20/15 hp). The Okuma 2SP-2500H runs twice as fast, 45–5,000 rpm against 25–2,500 rpm. Rapid traverse is close: 25 m/min (82 fpm) against 24 m/min (78.74 fpm).

Advantages
Okuma 2SP-2500H
- Twice the top spindle speed: 5,000 rpm against 2,500 rpm
- Slightly larger turning diameter: 410 mm (16.14 in) against 400 mm (15.75 in)
- Rapid traverse of 25 m/min (82 fpm) against 24 m/min (78.74 fpm)
Okuma 2SP-V40
- Longer turning length: 450 mm (17.72 in) against 200 mm (7.87 in)
- 22/18.5 kW (30/25 hp) spindle against 15/11 kW (20/15 hp)
- Suits heavy chuck work that seats better on a vertical spindle
Verdict
Choose the Okuma 2SP-2500H for short flanges, rings and discs within 200 mm (7.87 in) of turning length, where 5,000 rpm helps on the smaller diameters. Choose the Okuma 2SP-V40 for heavier, longer hub and ring parts: it turns up to 450 mm (17.72 in), has 22/18.5 kW (30/25 hp) and seats heavy work on a vertical spindle. Diameter capacity is nearly equal, so part length and weight decide.
