The simplest and most frequently used type of stylus, suitable for the majority of probing applications.

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. Ruby is regarded as the industry standard for stylus tips. It is one of the hardest materials available and suitable for most applications. Due to adhesive pickup, ruby tips are not recommended for scanning aluminium parts.
For most measurement occasions, ruby is one of the toughest materials with the industry standard and best characteristics. Artificial rubies were made in 2000 ° Alumina crystal (corundum) with purity of 99% was sintered by Verneuil process at room temperature.

Tungsten carbide rod is the best choice for the small diameter rod or super long rod with large stiffness. The small diameter rod is required for the stylus with ball diameter of 1 mm or less, while the length of super long rod can reach 50 mm. In addition, due to the possible deflection of the joint between the rod and the body, the weight may become a problem or the stiffness may be reduced.

*Application

• Always use styli that are as short and stable as possible
• With long styli components, ensure that they have the required stability
• Check that the styli you use have no defects, particularly on the thread and the seating area This will ensure that the mount is very secure
• Check that the probe component is firmly attached
• Replace worn styli
• Are your components thermally stable? Bear in mind the ambient conditions
• Avoid too many or different thread connections
• Use the lowest possible number of separate components
• Use the largest possible balls
• Large ball styli act as mechanical filters on the surface of the workpiece The fine structures on the surface of the workpiece are scarcely recorded with large balls, which prevents random measurement variations
• Styli should always be aligned at right-angles, or as close to a right angle as possible, to the planes being measured For angled measuring planes and angled bores, angled cubes and knuckles are available to ensure that styli are accurately aligned
• Ensure that the measuring force and dynamics suit the stylus components With small ball styli with a slim stem, you should reduce these values when necessary
