Rough charm

Hexagon Metrology has announced feature enhancements to the non-contact Precitec LR solution for high accuracy CMMs, enabling the optical sensor to be used for roughness measurement – in conjunction with the Quindos roughness software module – on a range of part types.

Designed to deliver accurate inspection results on even the most challenging workpieces, the Precitec LR uses focused white light to take measurements with particularly high accuracy at the submicron level. Featuring a large acceptance angle and high axial resolution, the sensor enables users to inspect complex parts with inclined, curved and aspherical surfaces and dispersive or reflective material types.

Available for the Leitz PMM-C, Leitz Ultra and Leitz Infinity models from Hexagon Metrology or as a retrofit option, the Precitec LR can be automatically exchanged with tactile sensors within a measuring program, turning the CMM into a multi-sensor solution for a variety of applications. With no handling differences compared to tactile probes and a measurement range that corresponds to that of the machine, minimal operator training is required.

“The Precitec LR is a really versatile optical sensor that integrates quickly and easily into a system and significantly improves the measurement potential of a CMM,” says Micha Neininger, product manager for sensors at Hexagon Metrology. “A very small spot diameter enables operators to use this non-contact solution for optical roughness measurements, making it possible to check surface variations even on fragile or malleable parts where tactile inspection is not an option.”
