Overview
The M-900iB/280 is FANUC's flagship heavy-duty arm, capable of handling 280 kg loads across a 2650 mm reach. Built for automotive body welding, structural assembly, and integration of complex sub-systems at production scale.
Technical Specifications
Reach 2650 mm, payload 280 kg, repeatability ±0.10 mm, cycle time 4.5–6.0 seconds per 2 m move. Operating envelope 5300×5300 mm, arm mass 970 kg.
Applications
Automotive body shell welding, large structural sub-frame assembly, engine block and transmission housing integration, press automation, and integrated material transfer across multiple workstations. Deployed globally in OEM lines.
Integration & Programming
Advanced iRVision, multi-gun welding packages, and full factory integration. Real-time trajectory optimization reduces cycle time by 15–20% compared to legacy programming.
Market Position
The industrial standard for large-scale automotive assembly, the M-900iB/280 has set industry benchmarks for reliability, repeatability, and throughput for over two decades.
FAQ
What is the typical cycle time for spot welding with the M-900iB/280?
For a 6-gun welding operation on automotive body, expect 4.5–6.0 seconds per weld sequence, enabling 600+ welds per hour in optimized layouts.
Can the M-900iB/280 handle structural welding on thick steel (10+ mm)?
Yes, the payload capacity and servo rigidity support thick-plate welding. Specialized gun mounts and thermal management are required.
What is the floor space requirement for a single M-900iB/280 installation?
The 5300 mm workspace envelope typically requires 6m × 6m floor space when including safety fencing, conveyor integration, and personnel access areas.
Is this robot suitable for integrated palletizing after welding?
Yes; the M-900iB/280 can handle finished assemblies (up to 280 kg) for immediate palletizing, reducing cell count and increasing throughput.
What is the installation time and commissioning period?
Factory setup takes 4–6 weeks; on-site commissioning and welding program validation typically require 2–3 weeks depending on complexity.
