68 TECHNOLOGY PLATFORM MILLER / September 2020 “The special thing about rollers is that the measurement has to be made in the radial direction and not, as is usually the case and easier, in the axial direction. Therefore, the development of rollDetect became necessary. It enables the simple positioning on the roll crosswise to the roll axis and thus reliable, always constant measuring results.” Reliable, consistent measurement results Interview with Martial Wüthrich from Diavite AG on measuring technique for rollers Martial Wüthrich Managing Director Diavite AG Martial Wüthrich heads the Swiss company Diavite AG for almost 20 years. Since 2009, the trained precision me- chanic has also been the owner of Diavite AG. The com- pany has been manufacturing roughness measuring in- struments since 1953 and has consistently improved and developed the technology ever since. Diavite AG is based in Bülach/Switzerland and works with numerous suppliers. The assembly is carried out by a small team in Bülach and the instruments are sold all over the world. As a specialist in the field of surface measurement, Dia- vite AG has developed a wide range of stylus for the most diverse applications. There are stylus for measurements on the inside of bores, on bottom surfaces or inner flanks of bores or grooves, of cutting edges and contours, of tooth flanks or axes as well as transverse and depth probes. A par- ticularly sophisticated design is a circumferential stylus for balls, tubes or shafts, whose mechanics follow the surface of the test piece in such a way that the probe tip always remains radially oriented to the curvature of the surface to be tested. The know-how acquired in solving such tasks en- ables the company to develop and supply tailor-made sen- sors even for very unusual tasks. This flexibility also applies to the development of adapted evaluation software.
