Werth TomoScope® coordinate measuring systems with computed tomography offer high measuring speed at high resolution. Transmission tubes with 80 W tube power allow measurements up to five times faster than conventional reflection tubes with the same structural resolution.
Werth TomoScope® coordinate measuring systems with computed tomography offer high measuring speed at high resolution. Transmission tubes with 80 W tube power allow measurements up to five times faster than conventional reflection tubes with the same structural resolution. OnTheFly CT for continuous acquisition of intensity images during rotation and real-time reconstruction of the digital workpiece volume simultaneously with image acquisition also contribute to the very high measuring speed. TomoScope® machines have high availability due to low maintenance requirements.
Proven long-life components allow maintenance-free operation for up to 12 months, maintenance work by the operator is completely eliminated. Standard-compliant calibration is optionally carried out by the Werth DAkkS laboratory, the first in the world for CT coordinate metrology systems.
In 2005, Werth developed the TomoScope® 200, the first CT machine for coordinate metrology. With a permissible length measurement error MPE for E up to (4.5 μm + L/75) μm, it was already possible to measure completely and accurately at that time. In 2011, the modern successor was introduced with a high tube voltage and high-resolution detector with compact external dimensions.
In the years that followed, larger CT machines for the measurement of difficult-to-penetrate workpieces with high resolution followed. From 2017, more compact CT coordinate measuring systems for fast measurements with high resolution were introduced with the TomoScope® XS device family.
High performance with optimal components
The new TomoScope® S Plus measuring systems have more than double the measuring volume of their predecessor, with almost the same size. With the unique specifications for the length measurement error MPE for E of (4 + L/75) μm and the distance deviation MPE for SD of (2.5 + L/100) μm, the series also offers what is certainly the highest accuracy in its machine class.
The modular machine system has been expanded. X-ray tubes from 130 kV to 240 kV tube voltage, with transmission or reflection target and with or without focusing, can be integrated. With tube voltages of up to 240 kV, the new TomoScope® S can be used to measure large workpieces that are difficult to penetrate. The detectors have 2 megapixels to 28 megapixels, with pixel sizes from 50 μm to 200 μm. The combination of large detectors and special tomography methods such as raster or half-side tomography enable a large measuring range of up to 650 mm. In addition, new operating modes such as laminography and OnTheFly eccentric tomography are available for the TomoScope® S series.
The new machines achieve an even higher measuring speed. With the help of the new cone beam artifact correction, fast, accurate measurement is possible with a small distance between the X-ray source and the detector. By using large and fast detectors, a larger part of the radiation energy is used. This allows a higher measuring speed or, by improving the signal-to-noise ratio for the same measuring time, a higher accuracy.
As with all Werth TomoScope® machines, the measurement time can also be greatly reduced by measuring many workpieces simultaneously.
