Spherical styli have the largest field of application because they have the same probing behavior in every direction. They are therefore suitable for all common measuring tasks such as measuring bores and surfaces. The larger the stylus sphere size, the larger the mechanical filter. This means that the profile of your workpiece is smoothened, which is often required in form measurement. The deviation from the ideal sphere shape is usually shown in Grade. ZEISS solid diamond stylus spheres have a grade 10 quality as standard. The stepped shaft has the advantage of a greater shaft thickness, which is reduced towards the measuring tip. This stepped shaft increases the stability of the shaft while maintaining the same length (depending on the sphere diameter). At the same time, however, the usable measuring length is reduced.

Diamond styli are characterized by their long durability. They are extremely resistant to material deposits and removal. They are, therefore, the ideal tool to use for measuring hard surfaces such as ceramics or for continous measuring on sharp edges. Diamond styli are recommended to be used especially when mostly one segment of the sphere is used while scanning e.g. surfaces. Several institutions such as the German PTB recommend diamond sytli for form measurements with the rotary table. ZEISS uses carbide shafts for standard styli. These represent a good combination in terms of weight, rigidity and thermal expansion.

Product note

Depending on the material of the styli and the workpiece, wear of the styli may occur. Therefore, we recommend to check the styli regularly for wear. Also remember to clean the styli or replace them if necessary. ZEISS Styli Cleaning Wipes are available.
