Overview

The Okuma MCR-C is the largest double-column machining center in Okuma's MCR lineup, built for the most demanding large-scale machining applications in industry. With X-travel configurations ranging from 4,200 mm to 12,200 mm (165.4 to 480.3 in), Y-travel from 3,200 to 4,200 mm (126.0 to 165.4 in), and Z-travel from 1,050 to 1,250 mm (41.3 to 49.2 in), the MCR-C machines workpieces measured in meters, not millimeters.

The spindle delivers 4,000 RPM standard with 45/37 kW (60/50 hp) through a No. 50 taper. An optional 37/30 kW (50/40 hp) configuration at 6,000 or 10,000 RPM provides higher surface speeds for finishing operations. The massive spindle motor power reflects the MCR-C's mission: removing large volumes of material from oversized workpieces in reasonable cycle times.

Table configurations range from 1,500 x 3,000 mm to 3,000 x 12,000 mm, with distance between columns from 2,650 to 3,650 mm. These dimensions define the machine's capability: it can handle workpieces measuring up to 12 meters in length. APC (automatic pallet changer) and AAC (automatic attachment changer) are available for production environments.

The tool magazine offers 50 tools standard with options up to 80, 100, 120, 180, 240, or 360 tools. The 360-tool capacity enables complex programs that run for hours without manual tool intervention, essential for lights-out machining of large components.

Double-column construction with box-way guides on all axes provides the structural rigidity needed when cutting forces act across a multi-meter work envelope. Okuma's Thermo-Friendly Concept manages thermal growth across the enormous machine structure, critical when dimensional tolerances must be maintained over distances exceeding 10 meters.

New MCR-C machines range from $800,000 to over $2,000,000 depending on configuration. At this scale, competitors include the SNK RB-6VM, Pama Speedram, and Waldrich Coburg PowerTec.

Strengths & Limitations

Strengths

X-travel up to 12,200 mm handles the largest industrial workpieces in automotive, aerospace, and energy sectors
45/37 kW spindle power provides aggressive metal removal rates on massive workpieces
Up to 360-tool magazine enables hours of unattended machining on complex large components
Double-column construction provides constant rigidity across the enormous work envelope
APC and AAC options support production machining of large components with head changes
Thermo-Friendly Concept manages thermal growth across multi-meter machine structures
Configurable to specific application requirements with extensive customization options

Limitations

Starting at $800K and exceeding $2M, the investment requires sustained high-value large-part production
Machine weight of 60-120+ tons requires purpose-built foundation and facility planning
Standard 4,000 RPM spindle is slow for finishing; higher-speed options sacrifice power
Lead times of 18-24+ months for custom configurations
Installation requires specialized rigging and potentially building modifications for machine access

Frequently Asked Questions

01 What does an Okuma MCR-C cost?

MCR-C machines range from $800,000 to over $2,000,000 depending on size configuration, spindle options, and tool magazine size. A 4-meter X-travel configuration starts around $800K; machines with 10+ meter X-travel and full automation exceed $2M. Lead times are 18-24+ months.

02 What facility requirements does the MCR-C need?

The MCR-C requires purpose-built facility planning. Foundation engineering for 60-120+ ton machines needs professional design with minimum 600 mm (24 in) reinforced concrete. Ceiling height must accommodate the crossrail and Z-axis stroke. Floor area varies from 10 x 8 meters for smaller configurations to 20+ x 10 meters for the largest. Crane capacity for installation typically needs 50+ tons.

03 How does the MCR-C compare to floor-type boring mills?

The MCR-C is a fixed-table design where the spindle moves over the workpiece. Floor-type boring mills move the workpiece on a floor plate. The MCR-C provides better accuracy because the heavy workpiece stays stationary. Floor-type machines are more flexible for irregular workpiece shapes. For precision die and mold work, the MCR-C is superior.

04 What industries use the MCR-C?

Automotive (body panel dies, large molds), aerospace (wing structures, fuselage components), energy (turbine casings, generator frames, wind turbine components), shipbuilding (engine beds), and heavy equipment (mining and construction equipment frames). Any industry producing precision components measuring multiple meters.

05 Can the MCR-C run unattended?

Yes, with the APC, AAC, and large tool magazine options (up to 360 tools), the MCR-C can run for extended periods without operator intervention. The Collision Avoidance System, tool breakage detection, and tool life management enable overnight and weekend operation. Chip management and coolant systems are sized for extended unattended runs.
