Overview

The Okuma MA-600HIII is the third generation of Okuma's 630mm-class horizontal machining center, delivering expanded axis travel and a comprehensive range of spindle options for medium-to-large workpiece production. With 1,050 mm X-axis, 900 mm Y-axis, and 1,000 mm Z-axis travel on 630 x 630 mm pallets, the MA-600HIII provides a generous work envelope for complex multi-face parts in automotive, aerospace, and heavy industry applications.

The standard No. 50 spindle runs at 6,000 RPM with 30 kW (40 hp) at 10-minute rating and 22 kW (30 hp) continuous. Five optional spindle configurations expand the machine's range: a 10,000 RPM No. 50 at 45 kW with 652 Nm torque, a 12,000 RPM wide-range option, a 6,000 RPM high-torque variant producing 1,071 Nm for difficult-to-machine materials, a 15,000 RPM No. 40 for high-speed aluminum work, and a 20,000 RPM HSK-A63 for ultra-high-speed finishing. Maximum workpiece size is 1,050 mm diameter by 1,200 mm height.

Tool storage accommodates 60 tools standard. Machine dimensions are 3,435 x 7,068 x 3,174 mm. The X-axis travel of 1,050 mm is longer than the previous MA-600HII generation, providing more flexibility for offset fixtures and complex tombstone setups. The machine runs on Okuma's OSP control with the full suite of intelligent technologies.

The MA-600HIII competes with the Mazak HCN-6800, DMG Mori NHX 6300, and Makino A81nx in the 630mm HMC class. Okuma's key differentiator is the breadth of spindle options — from 6,000 RPM high-torque at 1,071 Nm to 20,000 RPM HSK-A63 — covering everything from Inconel roughing to aluminum high-speed finishing. New MA-600HIII machines price in the $400,000 to $650,000 range. Specs sourced from Okuma Corporation published data.

Strengths & Limitations

Strengths

Six spindle options from 6,000 RPM high-torque (1,071 Nm) to 20,000 RPM HSK-A63 let shops configure the machine precisely for their primary application
1,050 mm X-axis travel (longer than previous generation) provides flexibility for offset fixtures and complex tombstone setups on 630mm pallets
1,071 Nm high-torque spindle option handles difficult materials like Inconel, titanium, and hardened steel that would stall lighter spindles
630 x 630 mm pallets with workpiece capacity to ø1,050 x 1,200 mm cover medium-to-large parts without stepping up to 800mm-class machines
60-tool standard magazine provides adequate capacity for most multi-face machining operations without expanded magazines
Thermo-Friendly Concept maintains accuracy across production shifts, critical for tight-tolerance aerospace and automotive work

Limitations

6,000 RPM standard spindle is slow for aluminum-focused shops — the 15K or 20K RPM options add significant cost but are necessary for high-speed work
Machine footprint of 3,435 x 7,068 mm is larger than 500mm-class alternatives, requiring more floor space per unit
No. 50 taper standard spindle is heavier than No. 40, limiting acceleration and adding to non-cutting time compared to lighter-taper machines
Pallet load capacity not prominently published — shops should verify for heavy tombstone configurations

Best For

Aerospace shops machining structural components in titanium and Inconel where the 1,071 Nm high-torque spindle handles difficult materials Automotive manufacturers producing engine blocks, transmission cases, and large castings on 630mm pallets Energy sector shops machining valve bodies, pump housings, and turbine components in alloy steels Job shops needing a versatile 630mm HMC that can be configured for everything from high-speed aluminum to heavy steel cutting Shops upgrading from MA-600HII to gain the expanded X-axis travel and latest intelligent technology features

Frequently Asked Questions

01 What does a new Okuma MA-600HIII cost?

New MA-600HIII machines typically price between $400,000 and $650,000 depending on spindle selection, tool magazine size, and automation options. The high-torque and high-speed spindle options add $30,000-$80,000 to the base configuration. Multi-pallet automation systems are available but add substantially to the total investment. Used MA-600H series machines from 2010-2020 trade between $150,000 and $350,000.

02 Which spindle option should I choose?

Standard 6,000 RPM No. 50: best for general steel and cast iron work. 10,000 RPM No. 50 (45 kW, 652 Nm): best all-around for mixed materials. 6,000 RPM high-torque (1,071 Nm): for Inconel, titanium, and heavy roughing. 12,000 RPM wide-range: balanced speed and torque. 15,000 RPM No. 40: for aluminum-focused production. 20,000 RPM HSK-A63: for high-speed finishing. Most versatile shops choose the 10,000 RPM No. 50 option.

03 How does the MA-600HIII compare to the Mazak HCN-6800?

Both are strong 630mm-class HMCs. The Okuma offers more spindle configuration options (6 vs typically 3-4 on the Mazak) and the Thermo-Friendly Concept. The Mazak counters with PALLETECH automation integration and higher tool magazine capacity. The choice often comes down to existing shop preferences — OSP vs MAZATROL control, Okuma vs Mazak service networks, and automation plans.

04 What improved on the HIII vs the HII?

The MA-600HIII extends X-axis travel to 1,050 mm (longer than the HII), adds updated intelligent technology features, and includes the latest OSP control platform. The expanded X-travel provides more flexibility for complex fixture setups and offset workpiece positioning on the 630mm pallets.
