GLOBAL Optics coordinate measuring machine

Bridge - High Accuracy

Optical high-resolution measurements of miniature size and form features on challenging surfaces

Equipped with a chromatic white light sensor as standard, GLOBAL Optics is ideal for non-contact measurement of the geometric size and form characteristics of sensitive workpieces that cannot be touched and those with particularly challenging surfaces.

An indexing probe head provides excellent access to part features from almost any angle and direction, allowing optimal alignment of the chromatic white light sensor to the measured surface. Furthermore, in combination with an automatic sensor changer rack, and thanks to Hexagon’s opto-mechanical sensor interface, different sensors can be easily exchanged on the indexing probe head, maximising the CMM’s multisensor flexibility.

Typical applications:

  • Orthopaedic implants
  • Stampings, stamping strips
  • Display glass for mobile devices

Non-contact size and form measurements on varied part surfaces:

  • Soft and sensitive parts that cannot be touched
  • Very small geometries (microgeometries)
  • Varied materials and surface finishes: matte / transparent/reflective, microstructured, coated

Benefits:

  • Optical high-resolution measurement for capturing the smallest geometric structures
  • Single‑point distance measurement and scanning of freeform surfaces
  • Surface-independent measurements
  • Thickness measurements on transparent materials

Automatic sensor changer rack

Adapt to specific application needs with fast and repeatable exchanges of sensor and styli configurations.

Sturdy mechanical design

The solid granite base with integrated dovetail guide guarantees long‑term system stability and consistent accuracy over the entire measurement volume.

High-speed and safety

Continuous monitoring of a defined safety area around the CMM allows worry-free high-speed measurement in CNC mode. The machine will slow down automatically when the user or an object encroaches upon the protected area.

Messaging lights

Messaging lights give operators the ability to monitor the machine’s status even from a distance, to optimise time and resource management.

Future-ready concept

The future‑ready pre‑cabling enables easy adaptation of the CMMs to future measurement tasks without costly downtime. A range of adaptability options can be flexibly selected during initial CMM configuration or set up later as upgrades.

Temperature compensation

Real‑time compensation of thermally caused measurement deviations through temperature sensing at the scales and on the workpiece ensures reliable measurement results.

Bridge with triangular crossbeam

Featuring an improved stiffnessto- mass ratio relative to square or rectangular traverses, this design allows for the highest dynamics and high‑speed measurements.

Preloaded air bearings on all axes

Contactless, low-friction and lowwear axis motion ensures fast and repeatable positioning at all speeds and accelerations, resulting in low measuring uncertainties.

Real-time system monitoring

PULSE enables the user to monitor and log any environmental conditions surrounding the CMM and receive real‑time machine information.

Extended temperature operating range

Measure your components with more resistance to environmental influences. An extended temperature operating range (15 – 30°C) allows the CMM to operate closer to the production line without needing a costly climate room.

Low-maintenance belt drive system

Flat and V-ribbed belts ensure smooth and low-vibration axis motion.

Multisensor versatility

Using the widest range of tactile and optical sensors with Hexagon’s universal sensor interface, the CMM becomes a multisensory inspection device that can adapt to the most complex measuring tasks with fully automatic sensor exchange during a measurement cycle.
