Machine Comparison
Index ABC vs Okuma 2SP-150H
Index-Traub vs Okuma · CNC Lathes
Summary
The Index ABC is a production lathe for short parts turned from bar. The Okuma 2SP-150H is a two-spindle chucker that turns short chucked parts in two operations, fed by a loader. The makers publish few comparable figures for this pair, so the table is limited to spindle and rapid traverse data.
On those three rows the Index ABC leads: 6,000 rpm against 4,500 rpm, a 20 / 27 kW spindle (100%/25% duty) against 11/7.5 kW (15/10 hp), and 30 m/min (1,181 ipm) rapids against 24 m/min (945 ipm). What the table does not show is how the work arrives: bar stock on the Index ABC, loaded blanks on the Okuma 2SP-150H.
Specifications Comparison
| Specification | Index ABC | Okuma 2SP-150H |
|---|---|---|
| Max Spindle Speed | 6,000 rpm ▲ | 50–4,500 rpm |
| Spindle Power | 20 / 27 kW (100%/25% duty) ▲ | 11/7.5 kW (15/10 hp) |
| Rapid Traverse | 30 m/min (1,181 ipm) ▲ | 24 m/min (945 ipm) |
Advantages
Index ABC
- 6,000 rpm top spindle speed against 4,500 rpm
- 20 / 27 kW spindle (100%/25% duty) against 11/7.5 kW (15/10 hp)
- 30 m/min (1,181 ipm) rapids against 24 m/min (945 ipm)
Okuma 2SP-150H
- Two spindles of equal rating handle both operations of a chucked part in one machine
- Loader-fed handling for short chucked parts that do not come from bar
Verdict
Choose by how the part is fed. The Index ABC is the pick for high-volume short parts cut from bar, and on the published rows it has the faster and stronger spindle, 6,000 rpm and 20 / 27 kW against 4,500 rpm and 11/7.5 kW (15/10 hp). The Okuma 2SP-150H is the pick for small chucked blanks that need two operations, where its two spindles and loader do the handling.
