FANUC M-710iC/20M vs ABB IRB 4600: 20 kg Robot Comparison
Updated: 8 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This comparison includes family-level ranges: FANUC M-710iC/20M lists 20 kg and 2582 mm, while ABB IRB 4600 lists 20–60 kg and 2050–2550 mm. Select an exact variant; maximum payload and maximum reach from different versions cannot be combined. |
→ CONSIDER FANUC M-710iC/20M Consider it when its named configuration already meets the actual load and workspace requirements. This article compares 20 kg with a published reach of 2582 mm; include the gripper and part in the load. |
→ CONSIDER ABB IRB 4600 Consider it when an exact variant in this family meets the complete tool load and required workspace. This article compares 20–60 kg with a published reach of 2050–2550 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose exact order codes before comparing capacity or price. Confirm the selected variant’s payload and reach together, then validate the real tool, movement path and controls against the same acceptance test. |
The FANUC M-710iC/20M and the ABB IRB 4600 cover almost the same envelope at 20 kg: 2582 mm for the FANUC and up to 2550 mm for the ABB. The IRB 4600 costs about 14% less and comes in versions up to 60 kg. The M-710iC/20M lists a broader set of processes, including laser cutting.
Quick verdict. The ABB IRB 4600 is the value choice for handling and machine tending, with 20 to 60 kg versions and a listed price $10,000 lower. The FANUC M-710iC/20M is the better choice for plants on FANUC that need 20 kg over 2.58 m for welding, sealing or laser cutting.

Price comparison
FANUC M-710iC/20M: listed from $72,000
ABB IRB 4600: listed from $62,000
Difference: $10,000
The IRB 4600 costs roughly 14% less
Reach and payload
At 20 kg the two are close: 2582 mm for the M-710iC/20M against 2550 mm for the longest IRB 4600. The IRB 4600 adds versions up to 60 kg with shorter reach, which suits heavier parts and double grippers in machine tending.
Processes and precision
FANUC lists handling, assembly, arc welding, sealing, mold handling, deburring and laser cutting for the M-710iC/20M. ABB uses the IRB 4600 for material handling, machine tending and process applications. Repeatability is close: ±0.06 mm for the FANUC and ±0.05 to ±0.06 mm for the ABB.
Installation and controllers
The M-710iC/20M weighs 530 kg and mounts on the floor, upside-down or at an angle. It runs on the R-30iB Plus (A- or B-cabinet) or R-30iB Mate Plus, while ABB runs the IRB 4600 on IRC5 or the newer OmniCore.
