Portable Measuring Arms

Modern portable CMM arms deliver high-precision, workshop-ready accuracy suitable for inspection, verification, and reverse engineering. Depending on the model, measuring volume, and set-up, they achieve repeatable results within microns — more than sufficient for most shop-floor and production applications.

A portable CMM arm brings metrology to the part, allowing inspection directly on the shop floor or on-site. A fixed CMM is installed in a controlled lab and requires parts to be transported for measurement. Portable arms offer speed, flexibility, and lower infrastructure costs, while fixed CMMs are best for ultra-high-precision, automated, high-volume inspection.

Working volume is the maximum size of the part you can measure. Choose a volume slightly larger than your largest component to ensure full reach and comfortable operation.

For example, small parts may suit a 1.3–1.8 m arm, while large fabrications and assemblies may require a 5–9 m arm. Selecting the correct volume ensures accuracy, efficiency, and long-term usability.

Choose 6-axis if your primary tasks are touch probing and dimensional inspection. Choose 7-axis if you need laser scanning, reverse engineering, or faster surface capture on complex parts. In short: probing = 6-axis; scanning and complex geometry = 7-axis.
