CMM 3Dis the latest generation of moving bridge style Coordinate Measuring Machine (CMM) from REESU. The high stability of measuring system can handle any common shop measurement and inspection tasks, therefore improve your inspection throughput.

Distinctive TRICISIONTM bridge design for X beam provides optimum stiffness-to-mass ratio.  The light alloy bridge is 25 percent stiffer than traditional designs and the X rail has a 50 percent lower center of gravity for smooth, precise movement.  Wider bearing separation than competitive bridge designs assures improved control of bridge axis roll for precise volumetric measuring accuracy, reduced repeatability errors, increased acceleration/deceleration and greater measuring throughput.

Panented precision-machined dovetail guideway in Y axis improves CMM’s accuracy and repeatability. 

From the base machine structure point of view, Function 3D features all-aluminum construction and utilized comprehensive CAD techniques, including Finite Element Analysis (FEA) and Module Analysis, with the result of improved thermal, dimensional/torsional, and geometrical stability and reduce structural deflection and the effects of vibrations and thermal variation on measuring performance. Wrap-around air bearing design optimizes the axis kinematics movement. Therefore the whole system characterizes the optimum measuring repeatability and long-term system consistency.
