Machine Comparison
Mazak Dual Turn 200 vs Okuma 2SP-150H
Yamazaki Mazak vs Okuma · CNC Lathes
Summary
The Mazak Dual Turn 200 and the Okuma 2SP-150H are both two-spindle lathes for turning both ends of a chucked part in one machine. The makers publish few comparable figures for this pair, so the comparison rests on three rows: chuck size, spindle speed and spindle power.
The Mazak takes the larger chuck, 8 in against 6 in (150 mm), and has the higher top speed at 5,000 rpm against a 50–4,500 rpm range. Spindle power is listed as 11 kW (15 HP) continuous for the Mazak and 11/7.5 kW (15/10 hp) for the Okuma, and the table treats that row as shared.
Specifications Comparison
| Specification | Mazak Dual Turn 200 | Okuma 2SP-150H |
|---|---|---|
| Chuck Size | 8 in | 6 in (150 mm) |
| Max Spindle Speed | 5,000 rpm ▲ | 50–4,500 rpm |
| Spindle Power | 11 kW (15 HP) continuous | 11/7.5 kW (15/10 hp) |
Advantages
Mazak Dual Turn 200
- Larger chuck: 8 in against 6 in (150 mm)
- Higher top spindle speed: 5,000 rpm against 4,500 rpm
- Suits running two different jobs at once on its partitioned left and right sides
Okuma 2SP-150H
- 6 in (150 mm) chuck matched to small-diameter chucked parts
- Suits short, loader-fed parts turned in two operations
Verdict
On the three rows published, the Mazak Dual Turn 200 is the choice for larger chucked parts: it holds an 8 in chuck and reaches 5,000 rpm. The Okuma 2SP-150H fits shops whose parts are short and small in diameter, held in a 6 in (150 mm) chuck and fed by the loader. Both list 11 kW (15 hp) at the spindle, so chuck size and part diameter should decide this pair rather than power.
