Overview

The Okuma MA-600HII is a high-performance, large-pallet horizontal machining center built for demanding production environments requiring precision and high material removal rates. With a 630 mm pallet, it accommodates the larger workpieces common in aerospace, heavy equipment, and die/mold applications, while maintaining the tight tolerances expected of Okuma's premium machine lineup.

The MA-600HII features a robust double-column structure that provides exceptional rigidity, minimizing deflection during aggressive roughing passes and ensuring geometric accuracy throughout the full work envelope. Okuma's Thermo-Friendly Concept provides continuous thermal compensation, maintaining part accuracy even during extended production runs without time-consuming warm-up cycles.

Equipped with a high-speed 15,000 rpm spindle and fast 60 m/min rapids, the MA-600HII does not sacrifice speed for capacity. The machine's pallet change system and large tool magazine support uninterrupted production, while optional FMS pallet pool integration enables multi-machine, lights-out manufacturing cells.

The OSP-P300S control, with its advanced features including Machining Navi, Collision Avoidance System, and real-time process monitoring, gives operators and programmers the tools to maximize productivity while protecting the investment in tooling and workpieces.

Strengths & Limitations

Strengths

630 mm pallet handles large aerospace frames, die blocks, and structural components
Double-column structure provides exceptional rigidity for heavy roughing and finishing
Thermo-Friendly Concept ensures dimensional stability throughout long production runs
Large tool magazine (up to 120 tools) supports complex workpieces without manual tool changes
Compatible with Okuma FMS pallet pools for automated multi-pallet lights-out production

Limitations

Significant floor space requirement and heavy machine weight demand careful facility planning
Premium investment level suits high-value, high-complexity workpiece environments best
BT50 tooling is bulkier and heavier than BT40, requiring appropriate handling equipment

Best For

Aerospace manufacturers machining large structural components, wing spars, and fuselage frames Die and mold shops producing large cavity blocks requiring multi-face 4-axis machining Heavy equipment suppliers machining gearboxes, housings, and large hydraulic manifolds Tier-1 automotive manufacturers producing large powertrain and structural components

Frequently Asked Questions

01 What is the maximum workpiece weight the MA-600HII can support?

The MA-600HII pallet supports workpieces up to 1,200 kg (2,645 lb), enabling it to handle very large castings, forgings, and fabricated structures common in aerospace and heavy industries.

02 What tool taper interface does the MA-600HII use?

The MA-600HII uses BT50 or HSK-A100 tool interfaces. BT50 is the traditional standard for large HMCs offering high torque capacity, while HSK-A100 provides improved rigidity and balance at higher speeds.

03 Can the MA-600HII be configured for full 4th-axis contouring?

Yes. The B-axis pallet rotator can be configured for full continuous 4th-axis contouring in addition to the standard precision indexing mode, enabling helical and complex contoured features in a single setup.

04 How does the MA-600HII maintain thermal accuracy?

Okuma's Thermo-Friendly Concept uses symmetrical machine construction and integrated thermal sensors to automatically compensate for heat-induced displacement in real time, maintaining accuracy without lengthy warm-up periods.

05 What is the X/Y/Z travel envelope of the MA-600HII?

The MA-600HII provides 900 mm of travel in all three linear axes (X, Y, and Z), giving it a 900 x 900 x 900 mm work cube suitable for large prismatic workpieces.
