Used Fanuc M-20iA: Sell or Buy at Auction
FANUC is the world's largest manufacturer of industrial robots and CNC systems, with a dominant position in factory automation globally. FANUC robots and CNC-controlled machines are ubiquitous in automotive, electronics, and precision manufacturing. The FANUC control system is the most widely installed CNC in the world.
The FANUC M-20iA is a six-axis industrial robot rated for a 20 kg wrist payload, with about 1,811 mm of reach and roughly ±0.08 mm repeatability. Most units on the used market run the R-30iA controller, though later builds shipped with the R-30iB, and the arm mounts on the floor, inverted, or at an angle, which is why it fits cleanly into tight CNC cells. FANUC positioned it for machine tending, material handling, and part transfer, and in practice it is one of the most common arms tending lathes and machining centers on the shop floor. Confirm the exact model tag before you buy or sell, since the family also includes a long-reach 12 kg variant, the M-20iA/12L at about 2,009 mm, and a higher-payload 35 kg variant, the M-20iA/35M. Automotive tier suppliers, precision machining shops, and systems integrators seek out this specific model because its mid-size payload drops into CNC load and unload cells, assembly, and light palletizing without the footprint of FANUC's larger arms. KD Auctions sees the strongest bidding when an M-20iA sells as a complete cell: arm, R-30iA or R-30iB controller, teach pendant, cabling, and the original end-of-arm tooling, with the program files intact, since that lets a buyer power it up and re-teach rather than rebuild. Demand runs international as well, reached through KD Auctions' network of 500,000+ industry contacts, with active bidding from Mexico, Asia, and Eastern Europe to retrofit these arms into existing R-30iA and R-30iB automation lines.

Frequently Asked Questions
What is a FANUC M-20iA robot worth at auction?
There is no single number. Value tracks the robot's age and generation, accumulated running hours, mechanical and servo condition, whether the R-30iA or R-30iB controller and teach pendant come with it, and the state of the original end-of-arm tooling and cabling. A clean, low-hour arm sold as a working cell brings far more than a bare, untested body. KD Auctions gives you a free AMEA-accredited, USPAP-compliant appraisal that sets both orderly liquidation value (OLV) and forced liquidation value (FLV) before you commit to a path. If you sell through a managed auction, plan on roughly 6 to 10 weeks from engagement to payout, with onsite dispatch within 48 to 72 hours. Commission is tailored to the engagement and quoted upfront, so most sellers pay nothing out of pocket.
How is the M-20iA different from the newer FANUC M-20iB?
The M-20iA is the earlier platform in FANUC's mid-payload M-20 family, rated at 20 kg and usually supplied with the R-30iA controller, with later units on the R-30iB. The M-20iB is the redesigned successor: it runs the R-30iB and R-30iB Plus, bumps payload (the M-20iB/25 carries 25 kg), and routes its air and signal cabling inside the arm and wrist to cut snag points in tight cells. For a shop already standardized on R-30iA programming, fixtures, and end-of-arm tooling, a matching used M-20iA is often the faster, lower-risk drop-in, which is why these arms stay in demand even as the M-20iB ships new.
