Portable Coordinate Measuring Machine
Hexagon Manufacturing Intelligence has introduced a new portable coordinate measuring machine (PCMM), the ROMER Absolute Arm 77 Series. This series comes in models ranging in measuring range from 2.5 m to 4.5 m. And the key of this new series is the level of accuracy provided by the arms. For example, there’s the smallest, the 7725, which has the 2.5-m range. It provides a probing point repeatability of 0.017 mm and a probing point volumetric accuracy of ±0.026 mm. Then, the largest, the 7745, with a 4.5-m range, offers a probing point repeatability of 0.060 mm and a probing point volumetric accuracy of ±0.174 mm.
