DN Solutions HC 400 II vs Okuma MA-12500H
DN Solutions vs Okuma · Horizontal Machining Centers
Summary
The DN Solutions HC 400 II and the Okuma MA-12500H are horizontal machining centers at opposite ends of the size range. The DN Solutions HC 400 II has a 400 × 400 mm (16 × 16 in) pallet and an ISO 40 spindle. The Okuma MA-12500H has a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet and a No. 50 spindle.
The Okuma carries more tools, 81 with 129 and 177 also listed, against 40. Rapid traverse is nearly the same despite the difference in size: 42 m/min (1,654 ipm) on the Okuma against 40 m/min (1,575 ipm). The case for the DN Solutions machine is that it is the smaller one, sized for small prismatic parts on a tombstone.

Advantages
DN Solutions HC 400 II
- 400 × 400 mm (16 × 16 in) pallet sized for small prismatic parts machined from a tombstone
- ISO 40 tooling, with smaller and lighter holders than No. 50
Okuma MA-12500H
- 1,250 × 1,250 mm (49.21 × 49.21 in) pallet against 400 × 400 mm (16 × 16 in)
- No. 50 spindle taper for heavy milling and boring, against ISO 40
- 81 tools, with 129 and 177 also listed, against 40
- 42 m/min (1,654 ipm) rapids against 40 m/min (1,575 ipm)
Verdict
These machines serve different jobs. Choose the DN Solutions HC 400 II for small prismatic parts machined on several faces from a tombstone, in production cells built around a 400 × 400 mm pallet and ISO 40 tooling. Choose the Okuma MA-12500H for large prismatic parts and heavy milling and boring that need a 1,250 × 1,250 mm pallet, No. 50 tooling and 81 or more tools. Rapid traverse, at 40 and 42 m/min, does not decide it.
