Machine Comparison
Haas EC-1600 vs Okuma MA-12500H
Haas Automation vs Okuma · Horizontal Machining Centers
Summary
The Haas EC-1600 and the Okuma MA-12500H are both large horizontal machining centers with 50-taper spindles. The makers publish few comparable figures for this pair, so the table covers only the spindle taper, the tool magazine and the rapid traverse.
Rapid traverse is the one row with a clear lead: the Okuma MA-12500H moves at 42 m/min (1,654 ipm) against 600 ipm (15.2 m/min). Its magazine is listed at 81 tools, with 129 and 177 shown in brackets as larger sizes, against 50+1 on the Haas EC-1600. The Haas EC-1600 takes CT or BT 50 tooling; the Okuma MA-12500H is listed with a No. 50 taper.
Specifications Comparison
| Specification | Haas EC-1600 | Okuma MA-12500H |
|---|---|---|
| Spindle Taper / Nose | CT or BT 50 | No. 50 |
| Tool Capacity | 50+1 | 81 [129, 177] |
| Rapid Traverse | 600 ipm (15.2 m/min) | 42 m/min (1,654 ipm) ▲ |
Advantages
Haas EC-1600
- Offered with either CT or BT 50 tooling
- 50+1 tool magazine suited to low-volume, long-cycle work on single large parts
Okuma MA-12500H
- Rapid traverse of 42 m/min (1,654 ipm) against 600 ipm (15.2 m/min)
- Magazine listed at 81 tools, with 129 and 177 shown as larger sizes, against 50+1
- Pallet-changing layout aimed at production of very large housings and casings
Verdict
The published rows separate these machines on rapid traverse, where the Okuma MA-12500H leads with 42 m/min (1,654 ipm) against 600 ipm (15.2 m/min), and on tool storage, 81 tools against 50+1. That fits its use on very large housings, casings and weldments in production. The Haas EC-1600 fits low-volume, long-cycle work on plates, frames and single heavy parts, where rapid speed is not the limit. Compare travels and table loads on each machine's own page before deciding.
