Sheffield Measurement has added a portable arm CMM, the Sigma Arm, to its North American product line.
The carbon fiber and aluminum, six-axis arm is designed for optimal stiffness with minimal weight. Most models weigh about 11 lbs.
Available in nine sizes ranging in spherical diameter from 71 in. to 203 in., the arm has volumetric accuracies from 25 to 100 microns, depending on arm size. Packages include the arm, probes, computer, software, and carrying case.
