LEITZ Reference Precision coordinate measuring machine

Bridge - Ultra-High Accuracy

High-precision fixed probe head measurements of tight tolerance parts

Leitz Reference Precision combines high accuracy and precision with outstanding high-speed scanning capabilities.

The model’s fixed scanning head ensures high, repeatable accuracy even with extra-long probe extensions and heavy styli clusters. This enables users to use high-accuracy scanning across a broader range of measurement applications, including inspecting features deep within parts. In addition, a modular sensor and styli changer rack enables the selection of the best styli options for each application.

Typical applications:

  • Precision tool holder
  • Watch plates
  • Tight tolerance precision gears

Highly accurate measurement of size and form features

  • Tight tolerance functional form features: straightness, flatness, roundness, cylindricity, line/surface profile
  • Filigree structures and microgeometrical features
  • Measurement of special geometrical features
  • Rotationally symmetric parts

Benefits:

  • High measurement system capability (Cg, Cgk, Gauge R&R)
  • Maximum accuracy and repeatability, even when using long and heavy styli configurations
  • Low force probing to avoid part bending or damage
  • Evaluation of all geometrical gear parameters
  • Non-contact measurements with chromatic white light and interferometric sensors
  • Simultaneous 4-axis scanning – optical or tactile – in combination with a rotary table

Fixed scanning probe

  • High accuracy form and profile measurements with high flexibility using heavy and long styli configurations.

Modular sensor and styli changer rack

Uninterrupted measurements with automatic multi-styli use within a single part program to adapt to different measurement tasks.

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.
