Mark 3 Linear Drive CMM

Mark 3 Linear Drive CMM
(X) 800mm x (Y) 1000mm x (Z) 600mm

The Mark 3 breaks new ground in design and innovation using frictionless linear drives, which are the key to its fast and exceptionally smooth motion.

The kinematic isolated drive structure is completely independent of the CMM structure and ensures that the motor thrust is directed through the centre of gravity of the moving parts. This not only avoids acceleration induced metrology errors but also has the effect of thermally isolating the motors from the metrology structure of the CMM.

Linear motors are non-contact and therefore have no wearing parts and thus provide the perfect solution for CMM drives, improving reliability and reducing maintenance. The Mark 3 is a standout machine with fast, smooth, silent motion ideally suited to contact scanning and with a first-term accuracy specification of under two microns.




• The most accurate machine in the Fowler FUSION range. First term volumetric error specification under 2μm.
• Linear motors offer frictionless, smooth, silent motion
• No wearing parts means greater reliability and reduced maintenance
• Drives applied through the centre of gravity improves both speed and accuracy
• Thermal isolation of motors from the metrology structure avoids thermally induced metrology errors
• Smooth motion allows fast and accurate contact scanning
• Automatic temperature compensation ensures that measurement results are reported as if they had been measured at 20°C
