Machine Comparison
Okuma MA-12500H vs Yasda YBM 7Ti
Okuma vs Yasda Precision · Horizontal Machining Centers
Summary
The Okuma MA-12500H and the Yasda YBM 7Ti are both large horizontal machining centers for heavy milling and boring of big prismatic parts, housings and frames. The makers publish few comparable figures for this pair: only the spindle taper and the tool capacity line up.
Both take No. 50 tooling as standard, the Yasda as MAS BT50. The Yasda YBM 7Ti can also be ordered with a 200-20,000 min-1 high-speed spindle, which is an extra-cost option and changes the taper to MAS BT40. On tools, the Okuma MA-12500H lists 81, with 129 and 177 as the larger magazines, while the Yasda lists 60 tools as standard and 90 tools or 120-450 tools as options.
Specifications Comparison
| Specification | Okuma MA-12500H | Yasda YBM 7Ti |
|---|---|---|
| Spindle Taper / Nose | No. 50 | MAS BT50 (MAS BT40 with the 200-20,000 min-1 high-speed spindle opt.) |
| Tool Capacity | 81 [129, 177] | 60 tools (90 tools/120-450 tools opt.) |
Advantages
Okuma MA-12500H
- 81 tools in the first listed magazine against 60 tools as standard on the Yasda YBM 7Ti
- No. 50 taper on every listed configuration
- Suits large prismatic parts and heavy milling and boring
Yasda YBM 7Ti
- Optional magazines of 90 tools or 120-450 tools, where the largest listed Okuma magazine is 177
- Optional 200-20,000 min-1 high-speed spindle on a MAS BT40 taper
- Suits mixed roughing and finishing, and pallet-pool production
Verdict
With only two comparable rows, the verdict rests on tooling. Choose the Okuma MA-12500H for heavy milling and boring of large prismatic parts where 81 tools, on No. 50 tooling throughout, is enough. Choose the Yasda YBM 7Ti if the work needs a very large tool pool, since its optional magazine runs to 120-450 tools, or if finishing calls for the optional 200-20,000 min-1 spindle on MAS BT40. Take travels, pallet size and spindle power from each maker's own data.
