Libra Ultra-High-Precision Fixed-Bridge CMM

A fixed-bridge CMM platform for ultra-precise measurement, stable scanning, and demanding laboratory environments.

Libra is built for applications where mechanical stability, low measurement uncertainty, and controlled motion matter most. Its fixed-bridge structure, granite construction, enclosed air-bearing layout, and high-resolution scale system make it a strong platform for ultra-precision dimensional measurement.

Best For

- Ultra-precision lab measurement for high-value parts and reference components.

- Complex profiles, freeform surfaces, molds, tooling, and fixture inspection.

- Critical dimensional validation where repeatability and room stability matter.

- Touch-trigger, analog scanning, and application-specific probing workflows.

Machine Structure

- Fixed-bridge architecture designed for high rigidity and measurement stability.

- Granite structure to reduce deformation from mechanical stress and temperature variation.

- Fully enclosed air-bearing layout for smooth, repeatable motion.

- Ultra-high-resolution floating glass scales.

- High-precision flexible ball screw drive on the moving platform.

- Optional precision vibration isolators based on model size, payload, site conditions, and accuracy target.

FAQ

Is Libra a fixed-bridge machine?

Yes. Libra uses a fixed-bridge structure to improve rigidity and measurement stability.

What environment does Libra need?

Libra should be installed in a controlled metrology room with stable temperature, controlled humidity, clean air, and low vibration.

Can Libra use scanning probes?

Yes. Libra supports touch-trigger, analog scanning, and laser scanning configurations depending on the selected package.

Is vibration isolation required?

It depends on the site, model size, payload, and accuracy target. Optional precision vibration isolators can be reviewed during configuration.
