Portable CMM fits in confined spaces

Hexagon Metrology has released the Romer Absolute Arm 1.2m portable CMM. It provides high-accuracy 3-D measurement in a 1.2-m volume, the company states. The unit is suitable for use in confined spaces, including inside a machining center for dimensional control of molds, parts, tooling, and castings.

A counterweight system allows the machine to be used without mountings on any surface. Standard-feature absolute encoders eliminate complicated referencing procedures. The operator can start measuring with a flip of a switch. Wireless battery-powered operation allows for shop floor portability, while an integrated camera and worklight facilitate inspections in harsh environments.
