Coord3 launches Universal range of moving frame bridge CMMs
1 min read
Italian co-ordinate measuring machine (CMM) company Coord3 has introduced its Universal range of high tech alloy, moving frame design, bridge-type CMMs that overcome the issues associated with operating traditional granite structures in less than perfect environments.

Coord3 Universal range also incorporates a wireless CMM thermal compensation system for both machine and part, allowing the measuring system to automatically and dynamically compensate for changes in the CMM operating environment. This system allows the CMM to perform within stated measuring accuracy between 16 and 26ºC. Gold-plated 0.1 µm measuring scales are free-floating in support tracks, eliminating any CMM structural changes from influencing measuring accuracy.
A highly rigid structural co-ordinate measuring platform allows the use of point-to-point, analogue contact scanning and laser scanning sensors, making the CMMs suitable for full 5-axis and gear measuring applications.
An isostatic design for each axis provides optimum machine geometrical alignment which facilitates accurate field calibration. Metrological performance also benefits from the monolithic base-plate, with integral inverted dovetail guideways, and a 90 by 90 mm Z ram section. Direct axis drives, using toothed drive belts, provide the vibration-free motion with zero hysteresis.
Universal CMMs can also be equipped with an optional SZP (Safety Zone Protection System) which uses laser scanners to monitor the defined protection zone when the CMM is in high speed automatic measuring mode. SZP reduces the CMM speed upon infringement of the safety zone by an operator and automatically returns the CMM to its full measuring speed, only after the zone infringement has been cleared. The SZP system allows safe use of the CMM in shopfloor and fully automated applications.
There is also a Nano Technology (NT) version of the Universal CMM that uses a silicon carbide Z ram and enhanced measuring scale system to provide higher speed scanning with further enhanced accuracy and a 0.3 µm reduction in measuring uncertainty.
The Coord3 Universal CMM family of machines is currently available with measuring strokes for the X-axis of 1,500, 2,000, 2,500 and 3,000 mm; Y-axis of 1,000 and 1,500 mm; and Z-axis of 900 and 1,000 mm.
