Obsolete FANUC CNC Control Parts Sourcing

Tens of thousands of machine tools still run FANUC Series 0, 0i and 16/18/21 controls — and FANUC keeps retiring their boards. We source A02B/A16B/A20B boards worldwide.

FANUC CNC controls are the most installed control platform in global machine tooling — and its older generations (Series 0, 0-C, 0i Mate, 16/18/21) have been discontinued or are in retirement, while the machines they drive keep cutting metal in job shops on every continent. When a master board, axis PCB or power unit fails, the original is often the only option: third-party refurbished boards exist, but parameters and PMC-L ladders live in the original hardware.

TGK Parts sources obsolete FANUC CNC parts through a global surplus network: decommissioned machine tools, OEM stock and verified refurbishers. Send the board number (e.g. A02B-0311-B520) or a photo of the board label — we reply within 12 hours with availability, condition and price, bench-tested where possible before shipping.

Our sourcing process (quote within 12 hours)

  1. Send the FANUC board number and a photo of the board label — include the control model from the machine nameplate (e.g. Series 0i-Mate-TC).
  2. We query the global surplus network and verified refurbishers, and confirm the exact board variant against your control generation.
  3. You receive a quote within 12 hours with condition stated clearly: tested surplus, refurbished, or new old stock.
  4. Bench testing where possible (power-up, boot self-test) before shipping — 12-month warranty on every unit.

Frequently asked questions

Can you source A02B boards that FANUC no longer sells?

Yes — A02B/A16B/A20B boards are a core sourcing line. Send the board number and control model; we reply within 12 hours.

Is a refurbished FANUC board safe to install?

From verified refurbishers, yes — boards are tested on a compatible control before shipping. We only source refurbished boards with a functional test report.

Do you supply the PMC-L ladder with the board?

Parameters and ladders usually stay in the machine's memory, not the board — but where the seller provides them we pass them on. Always keep a current SRAM backup before any board swap.

Can you source a complete Series 0i control unit?

Occasionally as surplus from decommissioned machines. More often we source the individual failed board, which is faster and far cheaper.

My board number is unreadable — can you still help?

Send a clear photo of the board and the machine's control nameplate; FANUC board numbering follows the control generation, so we can usually identify the family and confirm the exact variant with the refurbisher.
