Jenoptik Industrial Metrology’s optical shaft measuring devices ensure precision in the shortest possible measuring cycle times, the company says. The single-camera solution permits the measurement of workpieces of as much as 80 mm in diameter without any loss of resolution. Accuracy with MPE values (maximum allowable error) of less than 2 microns are typical.

The Hommel-Etamic Opticline series is especially useful for production-floor evaluation of shaft-like parts as large as 150 mm in diameter and 900 mm in length with enhanced performance and functionality. Opticline series products feature a 0.1-micron high-resolution camera, with enhanced measurement accuracy and increased measurement frequency during the measurement cycle.

Optical measurement of workpiece profiles, diameters and spacing, angle or radii, threads, rotation angles, form (and geometric tolerances), or outer contours of high precision workpieces can be determined quickly and flexibly within a compact floorspace, the company says. For checking length and angular measurements, an optional touch probe is available.

The optical system is hermetically sealed, which is said to prevent dust or oil mist from interfering with the measurements. Active self-monitoring mechanisms and temperature compensation have been optimized, improving the long-term stability of the measuring device.

Making the system easier to use and quicker to respond to changes in part designs, the series has a more ergonomic design and features an open and widely accessible part loading area. The controls are clearly arranged and easy to reach, the company says. Also, light curtains protect the operator from intervention in dangerous areas.
