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

The granite table and granite Y-axis rail has been designed to take full advantage of the natural thermal density of this remarkable material. The Y-axis linear drive system has been positioned away from the Y-axis linear encoder so that the heat generated by the linear drive is absorbed by the granite without affecting metrology performance. sl arora physics class 11 pdf

Drawing upon the tremendous success of the Horizon, the Horizon L has a larger X-Y-Z axis travel whilst utilising the same frictionless linear drives. Use search strings like: "SL Arora Physics Class

The entire design of the Horizon L has been optimised to take full advantage of parts already used on the Horizon whilst improving the stiffness-to-weight ratio across the bridge assembly. Most notably: The Y-axis rail is 200mm taller so that the same right-hand-side linear drive system is common and improves rigidity; the carriage assembly has reduced in size and weight, without compromising metrology performance, to improve the stiffess-to-weight ratio; the Z-axis motor has increased power to optimise its performance; the left-hand-side air bearing assembly has a custom extruded profile to keep weight to an absolute minimum and maintain stiffness.
