World's most accurate multisensor coordinate measuring machine

With the VideoCheck® UA, the potential of highly accurate sensors can be fully exploited. Werth Messtechnik probably has the largest selection of such sensors, such as the patented Werth Fiber Probe® 3D, the Werth Chromatic Focus Point sensor or the Werth Interferometer Probe. Prof. Dr.-Ing. Michael Marxer, Head of the Competence Center for Production Metrology at the University of Applied Sciences OST in Buchs: "With the Werth VideoCheck® UA, we have a large number of tactile and optical measuring machines available on one measuring machine, which we can use optimally for a very wide range of ultra-precise measuring tasks. We achieve the smallest measurement uncertainties at high measuring speeds."

With the new accuracy-optimized design, the MPE for Euni has been reduced to (0.15 + L/2000) μm (optional). The new machines have improved decoupling from ambient vibrations, improved long-term temperature stability and thus minimal influence on the sensor offset for improved measurement uncertainty in multi-sensor systems. This has further increased accuracy, especially for time-consuming multi-point measurements with several sensors in the same datum system. Marxer: "The VideoCheck® UA enables us to measure workpieces economically and calibrate calibration standards with high precision in new areas of application with the highest requirements. In combination with the user-friendly software, the machine is a universal tool for us that exceeds our high requirements."

The revised device concept is characterized by temperature-stable components, optimized heat circulation, active cooling of components and extended software temperature compensation. Liebrich: "In Werth Messtechnik, we have found a partner that meets our high requirements with a wide range of sensors and also continuously improves its multisensor coordinate measuring machines through various optimizations. We greatly appreciate the open and constructive exchange with the Werth Messtechnik team."
Other prerequisites for the improved specification of the VideoCheck® UA are new procedures and the utmost care in qualifying the software corrections, for example exact specifications to achieve thermal equilibrium. Many calibration standards are not accurate enough to prove the low size and form error of the highly accurate sensors on the VideoCheck® UA. For example, a special ultra-precision sphere had to be created for the Werth Fiber Probe® 3D.
