Description

Straight styli are designed to inspect simple features where direct, unobstructed contact with a measured surface is possible. A tungsten carbide stem provides exceptional rigidity, particularly for styli with small ball and stem diameters. Silicon nitride is a very hard and wear resistant ceramic which can be machined into very high precision spheres. It does not have the attraction to aluminium and so does not exhibit the adhesive wear seen with ruby in similar applications.
