Portable 6-axis CMM arm has optimal stiffness

A six-axis portable arm CMM, constructed of carbon fiber and aluminum, is designed for optimal stiffness with minimal weight for measurement of large objects.

Sheffield Measurement announced today the addition of a portable arm CMM, the Sigma Arm to its North American product line.

The product is available for immediate quotation throughout Sheffield's North American distribution network.

Constructed of carbon fiber and aluminum, the six axis Sigma Arm is designed for optimal stiffness with minimal weight; most models weigh about 11 pounds.

Portable arm CMMs are ideal for measurement of large objects where bringing the CMM to the workpiece is more practical than bringing the workpiece to a stationary CMM.

Inspection of sheet metal, tubes, plastics, wood, and concrete are all possible with the Sigma arm.

Equipped with either touch probing, non-contact tube or laser probes, and various software options, including Hexagon Metrology's popular PC-DMIS software package, the Sigma arm is a complete measurement solution.

The Sheffield Sigma articulated arm CMM is available in nine sizes, ranging in spherical diameter from 71in up to 203in, with volumetric accuracies ranging from 25 to 100 microns, depending on the size of the arm.

Complete packages include the arm, probes, computer, software and carrying case.

Sheffield Measurement, is part of the Hexagon Metrology group of Hexagon, a multinational publicly traded corporation with over $1.2 billion in annual revenue.

Hexagon Metrology's brands include Brown and Sharpe, Romer, Cimcore, Sheffield, PC-DMIS, CEJohansson, TESA, Leitz, and DEA.
