Machine Comparison
Okuma MA-12500H vs Starrag Heckert H55
Okuma vs Starrag · Horizontal Machining Centers
Summary
The Okuma MA-12500H and Starrag Heckert H55 are horizontal machining centers of different sizes. The Okuma has a 1,250 × 1,250 mm (49.21 × 49.21 in) pallet and a No. 50 spindle for large parts; the Starrag has a 500 x 500 mm (19.7 x 19.7 in) pallet and an HSK-A63 spindle for precision prismatic work.
The H55 rapids at 60 m/min (2,362 IPM) against 42 m/min. Tool storage depends on options: the MA-12500H starts at 81 with 129 or 177 optional, the H55 at 60 with 120 or 240 optional. Control is Okuma's OSP-P500M against Siemens SINUMERIK 840D sl or Fanuc 31i-B on the Starrag, a useful choice for shops standardized on either.

Verdict
These machines serve different jobs. The Okuma MA-12500H is for heavy equipment, energy and mining parts that need a 1,250 × 1,250 mm pallet and a No. 50 spindle. The Starrag Heckert H55 is for aluminum, titanium and Inconel prismatic parts on a 500 x 500 mm pallet in automotive and aerospace production, where 60 m/min rapids and a Siemens or Fanuc control fit an automated cell. Part size decides.
