Machine Comparison
Kitamura Mycenter HX630iG vs Okuma MA-12500H
Kitamura vs Okuma · Horizontal Machining Centers
Summary
The Kitamura Mycenter HX630iG and the Okuma MA-12500H are both 50-taper horizontal machining centers, but they are built around very different pallets: 630 x 630 mm (24.8 x 24.8 in) on the Kitamura against 1,250 × 1,250 mm (49.21 × 49.21 in) on the Okuma. Pallet size is the headline difference, and it decides which parts each machine can take.
The Kitamura is the faster mover, with rapid traverse of 60 m/min (2,362 ipm) against 42 m/min (1,654 ipm). The Okuma starts with the larger magazine, 81 tools against 60 tools standard; options take the Kitamura up to 120 and the Okuma to 129 or 177. The Kitamura takes BT50 tooling, with HSK-A100 as an extra-cost option, and the Okuma has a No. 50 spindle.

Advantages
Kitamura Mycenter HX630iG
- Faster rapid traverse: 60 m/min (2,362 ipm) against 42 m/min (1,654 ipm)
- HSK-A100 spindle available as an extra-cost option alongside the standard BT50
- Sized for mid-size steel and iron parts on a 630 x 630 mm (24.8 x 24.8 in) pallet
Okuma MA-12500H
- Larger pallet: 1,250 × 1,250 mm (49.21 × 49.21 in) against 630 x 630 mm (24.8 x 24.8 in)
- 81 tools in the standard magazine against 60 tools
- Magazine options of 129 or 177 against up to 120 on the Kitamura
Verdict
Choose by part size. The Kitamura Mycenter HX630iG suits steel and iron parts and fixtures that fit a 630 x 630 mm pallet, and its 60 m/min rapids shorten the non-cutting time on that work. The Okuma MA-12500H is for large prismatic parts that need a 1,250 × 1,250 mm pallet and for long operations that draw on 81 or more tools. Both take 50-taper tooling, so the pallet, not the spindle nose, should settle the choice.
