Werth introduces what it claims is “world’s most accurate” coordinate measuring machine

Werth TomoCheck HA 200Werth Messtechnik GmbH (Giessen, Germany) is introducing its new TomoCheck HA (High Accuracy) 200, a coordinate measuring machine (CMM) with computed tomography sensor that Werth claims is the “world’s most accurate” CMM. By combining transmission tubes with up to 225-kV acceleration voltage and large, high-resolution detectors, Werth said that both multi-material assemblies and large-volume workpieces can be measured at high resolution with previously unattainable accuracy.

A granite base structure, high-precision mechanics and air-bearing technology make it possible to achieve a maximum-permissible error of just MPE E1 = (0.5 + L/500) microns or MPE E = (2.5 + L/150) microns. Probing error of the X-ray sensor is minimized using a patented process. The diamond target tubes and a detector with a high pixel count help the computed tomography machine achieve resolutions in the 1/10 micron range. Like all CMMs from Werth Messtechnik, additional sensors can be retrofitted for specific applications, said the company.

With WinWerth 3D measurement software, all operator control steps from data recording to nominal to actual comparisons are performed on the CAD model. Software tools for material analysis, such as cavity and crack inspections, are also available.

Precision and micro components made of various materials, such as automobile injector parts, are the main application for the TomoCheck HA 200.
