Quick overview

Star stylus with M2 thread, ruby ball Ø0.5 mm, tungsten carbide stem Ø0.36 mm, span 19 mm. For use on coordinate measuring machines (CMM).

The stylus is an important part of the measuring system. During the measurement, the stylus is in direct contact with the part.
A star stylus configuration is made of multiple styli for maximum flexibility. It can also be used to significantly reduce the number of tool changes during the measurement cycle. Any number of styli can be combined to create a star configuration. Depending on the application, different materials for stems and tips are available.

Ruby is the most widely-used material for stylus tips. Thanks to its inexpensive price and high quality, it is the standard choice for most applications. It is an extremely hard material, which tends, however, to cause material build-up when combined with certain materials such as aluminium.

A tungsten carbide stem has high stiffness and less thermal expansion, compared to stainless steel.
