HEXAGON METROLOGY - ROMER ARM
Metrology Industry. Portable coordinate measuring machines (CMM).
Previous Limiting Technology
Steel and/or aluminum cylindrical tubing.
Cylindrical shafts needed to exhibit less thermal expansion/contraction (dimensional change) during temperature fluctuations. Stiffer and lighter support structure also beneficial for higher precision and portability.
High modulus carbon fiber/epoxy composite tubing bonded to machined metallic joints creating an ultra-lightweight articulating arm capable of 3 dimensional measurements accurate to within 3 microns or less.
