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 styli spheres have Grade 5 as standard, but can also be offered in a higher Grade 3 for special requirements. Styli with a straight shaft are the most simple designed styli. The full shaft length can be used as measuring length.
Ruby styli are the standard for almost all applications and are available in a variety of different diameters. Another advantage is that ruby spheres can be produced in very small diameters (from 0.12 mm). On the other hand, ruby has weaknesses at the continuous scanning of certain materials and surfaces. With extremely soft materials, e.g. aluminum, material from the workpiece can be deposited on the ruby surface (material deposit). Very hard and rough surfaces, e.g. castings, on the other hand, cause abrasion of the sphere (material removal). The shape of the sphere changes as a result and loses accuracy. ZEISS uses carbide shafts for standard styli. These represent a good combination in terms of weight, rigidity and thermal expansion.
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 stylus cleaning Wipes are available.
