Extol CMM


Next Generation of Shop Floor Hardened, Non-cartesian CMM

True to Aberlink's heritage for innovation, the Extol is the world's first CMM to utilise a delta mechanism.

Designed for robustness and reliability, the Extol CMM will run around the clock making it ideal whether it is positioned next to a machine tool, in a manufacturing cell, or used in a dedicated inspection area.

Five temperature sensors monitoring both the machine and ambient temperature ensure that the Extol is capable operating in uncontrolled environments and reporting measurements as though they had been taken at 20°C. The software will also produce a warning should the temperature be changing at a rate that is not conducive with reasonable metrology practice.

Robust, accurate and reliable, the Extol CMM is the perfect solution to automatically verify part quality for critical components.


The automatic tool offset correction available with the Aberlink 3D software compliments the attributes of the Extol perfectly allowing utilisation as part of a fully automated production process in the midst of a manufacturing environment.

Superior Design

The ergonomics of the Extol have also been a significant design factor. It is not only quick and easy to perform one-off inspections, but also has ample access for either batch inspection or to facilitate automatic loading. With a larger measuring volume and smaller overall footprint than its predecessor, the Xtreme, the Extol can be positioned exactly where the measurement is needed.


The Extol can now be supplied with a SP25M scanning module, increasing inspection speed for complex parts and allowing even more functionallity for our most robust shop-floor CMM yet. Clever implementation and low profile mounting allows the probe to be switched between scanning and touch-probe effortlessly, giving you more freedom for your shop floor measurements.
