(Exact Metrology: Moline, IL) -- Exact Metrology, a comprehensive 3D metrology service provider and hardware sales company, is excited to announce that a large scale Coordinate Measuring Machine (CMM) has been installed at their office location in Moline, Illinois.

This machine is a high-accuracy CNC coordinate measuring machine that guarantees a maximum permissible error of E0, MPE = (2.5+3L/1000) μm. With this machine, measurement uncertainty remains within one-fifth of the dimension tolerance up to 30.2” (766 mm). The higher accuracy specification therefore gives it more than double the effective measuring range in terms of accuracy-guarantee capability.

In addition, the room the machine sits in is temperature controlled. From sensors installed on each axis scale and working in conjunction with sensors placed on the workpiece, temperatures are obtained before outputting the measurement result to the controller. The combined axis scale/workpiece temperature compensation design used gives superior results compared to systems with sensors only on the axis scales.
