Fast and non-contact
An optical sensor can measure an object without having to follow the contours. This eliminates the need for infeed movements between the actual measuring movements in some cases. In other cases, such movements can be made simpler and thus faster. At the same time, the object to be measured is not manipulated even during extremely fast movements. This is therefore referred to as a non-reactive and fast measurement.

Fast and precise
Many gears have precision requirements significantly below one micrometer. The surfaces are often quite smooth, highly reflective and, because of the minimal scattered light components, present a particular challenge for optical metrology. This is compounded by steep flank angles in gearings, which lead to shadows and multiple reflections. And in the harsh environment of a shop-floor measurement, impurities can compromise the results of an optical measurement.

With sophisticated measuring sequences, smart data handling and the use of optimized sensor technology, Klingelnberg optical metrology makes it possible to achieve a highly accurate gear measurement. Despite this high optical accuracy, however, the system is not practical for use in all application scenarios. How do KLINGELNBERG Precision Measuring Centers manage to provide the optimal solution for all applications?

KLINGELNBERG hybrid metrology – tactile and optical metrology skillfully combined
Optical metrology offers advantages for certain gear measurement tasks, such as when digitizing an entire, possibly unknown component, or when measuring splines or miniature gears quickly yet completely. The high measurement speed of an optical system with an extremely high point density allows for measurements that would be difficult and time-intensive if performed with a tactile system. This also enables cost-effective measurements outside a purely academic environment and is designed for use in an industrial setting.

In order to be equipped for all measurement tasks, however, Klingelnberg combines optical metrology with the established, high-precision 3D-NANOSCAN probing system. This system combines maximum precision with the required robustness for a production environment. High-speed changeover between the two measurement systems allows the optimal system to be used for every task.

Whenever high-precision measured values are required for a task, the 3D NANOSCAN is the system of choice, and for a rapidly generated, dense point cloud, the HISPEED OPTOSCAN is now available. Combined with the available roughness measurement technology, KLINGELNBERG Precision Measuring Centers are the cost-effective solution for all precision measurement tasks: fast and precise!
