The FANUC A02B‑0281‑B803 is an industrial CNC control chassis / basic unit used in FANUC CNC systems. It’s part of the A02B-0281 product series and serves as a modular foundation for building or repairing CNC controller systems.

-
OEM builds of CNC systems
-
Retrofit projects to replace worn or outdated control bases
-
Spare parts inventory to reduce machine downtime
