Your CNC machine on your PC.

Create a perfect CNC digital twin of your shop floor.
Simulate the exact kinematics, controller logic, and tooling in full 3D.

What is a CNC digital twin? It is an exact virtual replica of your physical CNC machine, including its 3D geometry, kinematics, and the specific behavior of its controller. With Eureka3X, your CNC digital twin allows you to verify NC programs exactly as they will run on the real machine.

💻 Windows 10/11 Required

Trusted by professionals who can't afford mistakes

Eureka3X is built on Eureka Virtual Machining — 20+ years of industrial CNC simulation, used in production by world-class manufacturers.

Sound familiar?

These happen every week in every shop. Eureka3X fixes all three.

THE PROBLEM

Testing on the real machine

Proving out a new program on a $500k machine wastes valuable spindle time and risks severe damage.

THE FIX

Prove out on the digital twin

Eureka3X gives you a perfect digital replica. Prove out the program offline while the real machine keeps making chips.

THE PROBLEM

Unpredictable cycle times

CAM estimates are often wrong because they don't account for the machine's true acceleration and deceleration.

THE FIX

Accurate cycle time calculation

The digital twin simulates the true kinematics and controller parameters, giving you accurate cycle time estimates.

THE PROBLEM

Hidden setup collisions

You can't see what's happening inside the machine envelope until the coolant is off and the doors are open.

THE FIX

Full visibility in 3D

Rotate, zoom, and inspect every detail of the machining process in a safe virtual environment before cutting.

The math is obvious.

A spindle crash means

Days or weeks offline
Every day of downtime erases margin
Costly machine repair
Spindle, fixture, and tooling damage
Scrapped parts and missed deliveries
Reputation damage on top of material loss

Eureka3X protects you

One crash costs more than a year of Eureka3X. Load your G-code, run the simulation, see the crash on screen — not on the machine.

Frequently Asked Questions

+What is a CNC digital twin?

It is a virtual representation of your CNC machine that behaves exactly like the real one, simulating kinematics and controller logic.

+Do I need to build my own digital twin?

No, Eureka3X includes 4 production-ready digital twins (Fanuc, Haas, Siemens, Heidenhain) out of the box. You can also import your own CAD models to build custom machines.

+Does it simulate controller parameters?

Yes, Eureka3X uses a highly accurate mathematical model that considers acceleration, deceleration, and specific controller settings for precise cycle time estimation.

+What happens after the trial?

After 30 days, your trial will expire. If you want to continue using the software, you can upgrade to one of our plans. There is no automatic charge since we don't ask for your credit card upfront.
