OKK HM1000S vs Okuma MA-12500H
OKK Corporation vs Okuma · Horizontal Machining Centers
Summary
The OKK HM1000S and the Okuma MA-12500H are both large horizontal machining centers with a No. 50 spindle taper. The makers publish few comparable figures for this pair, so the table covers only pallet size, taper and rapid traverse.
The Okuma MA-12500H has the larger pallet, 1,250 × 1,250 mm (49.21 × 49.21 in) against ⌀1000 mm on the OKK HM1000S. The OKK HM1000S has the faster rapid traverse, 48 m/min (X, Y, Z) against 42 m/min (1,654 ipm).
Specifications Comparison
| Specification | OKK HM1000S | Okuma MA-12500H |
|---|---|---|
| Pallet Size | ⌀1000 mm | 1,250 × 1,250 mm (49.21 × 49.21 in) |
| Spindle Taper / Nose | No. 50 | No. 50 |
| Rapid Traverse | 48 m/min (X, Y, Z) ▲ | 42 m/min (1,654 ipm) |
Advantages
OKK HM1000S
- Faster rapid traverse: 48 m/min (X, Y, Z) against 42 m/min (1,654 ipm)
Okuma MA-12500H
- Larger pallet: 1,250 × 1,250 mm (49.21 × 49.21 in) against ⌀1000 mm
Verdict
On the published rows, the choice comes down to pallet size against traverse speed. Choose the Okuma MA-12500H when the part or fixture needs a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet. Choose the OKK HM1000S when the work fits a ⌀1000 mm pallet and its 48 m/min rapids are useful. Both take No. 50 tooling. Travels, load and spindle figures are not in this table, so check each machine's own page before deciding.
