What Is FANUC FA? Factory Automation Products and Systems Explained
FANUC FA refers to the Factory Automation business of FANUC — the part of the company that supplies the control and drive technology inside machine tools and production equipment, rather than the articulated robots that handle and move parts. If you are trying to understand how a CNC machine, a servo axis, or a laser cutting system is controlled, you are looking at FA. If you are trying to understand how a part is picked, welded, or palletized by a robotic arm, you are looking at the ROBOT business instead. The two sit side by side on FANUC's global site and are frequently installed in the same factory, which is why they are easy to confuse.
What "FA" covers at FANUC
FA is the umbrella for the automation products that make machines move and cut precisely. On FANUC's global site, the FA-related offering is organized around a small number of core categories:
- CNC systems — the numerical controls that command machine tools such as machining centers, lathes, and grinders.
- Servo motors and drives — the motion components that execute the commands from the control, positioning axes and spindles.
- Lasers — laser oscillators and related equipment used for cutting and other laser-based processing.
- ROBOMACHINE series — compact, self-contained production machines that FANUC builds and sells as complete units.
These categories are not independent products so much as layers of one control chain: the CNC decides what motion is needed, the servo system produces it, and the machine — whether a customer's machine tool or a FANUC ROBOMACHINE — is the physical result.
How FA differs from FANUC's robotics business
The cleanest way to separate them is by what the product actually does.
| Dimension | FA (Factory Automation) | ROBOT |
|---|---|---|
| Core function | Control and drive machine motion and processing | Manipulate and move workpieces, tools, or parts |
| Typical products | CNC systems, servo motors, lasers | Industrial robot arms and their controllers |
| Typical host machine | Machine tools, production equipment | Work cells, lines, machine tending setups |
| Where it sits | Inside the machine, as its control and drive | Alongside or between machines, as the handler |
A practical example: a machining center cutting a metal housing uses a FANUC CNC and FANUC servo motors — that is FA. A robot arm loading the raw casting into that same machining center is a FANUC ROBOT. Both may report to the same plant network, but they are sold and supported as different product families.
Where FA products are used
FA technology appears wherever a machine has to follow a precise, repeatable motion path or cut. That includes:
- Machine tools — milling, turning, grinding, and similar metal-cutting equipment built by machine tool manufacturers who integrate FANUC CNC and servo systems.
- Production equipment — specialized manufacturing machines that need coordinated axis control.
- Laser processing — cutting and related operations using FANUC laser sources.
- ROBOMACHINE installations — compact machining, injection molding, wire-cut EDM, and nano-precision machines that FANUC supplies as complete systems rather than as components to another builder.
The distinction matters when you are specifying or troubleshooting: in a machine tool, FA is usually the control and drive that the machine builder integrated; in a ROBOMACHINE, FANUC supplies the whole machine.
How FA, ROBOT, and ROBOMACHINE relate on FANUC's site
FANUC's global site lists FA, ROBOT, and ROBOMACHINE as separate product areas, and that separation reflects how the products are bought and serviced:
- FA is the component and control layer — what machine builders and integrators embed.
- ROBOT is the automation layer — what end users deploy to move and handle parts.
- ROBOMACHINE is the finished-machine layer — complete production machines sold under FANUC's own name.
A ROBOMACHINE therefore contains FA technology (its CNC and servo system) but is catalogued separately because you buy it as a machine, not as a control. This is the main reason the three categories overlap in a real factory yet stay distinct in FANUC's product structure.
Where to start exploring specific FA products
If you already know which layer you need, go directly to that section of FANUC's global site:
- Need a control or drive for a machine you are building — start with the FA / CNC and servo sections.
- Need a laser source for cutting — start with the laser section under FA.
- Need a complete compact production machine — start with ROBOMACHINE, then check which FA control it uses.
- Need to move parts between machines — that is the ROBOT section, not FA.
For each product, the site's own pages are the reliable source for current models, specifications, and regional availability; FANUC's global site also lists locations and service contacts, which is the right next step once you have identified the product family you need.
