Recommended Styli - Renishaw RMP400 Installation Manual

Recommended styli

High modulus carbon fibre styli are designed to
minimise pre-travel and improve accuracy, as
the stem material is extremely stiff. This inherent
stiffness makes the following styli most suitable for
strain gauge applications.
Part number
A Ball diameter mm (inch)
B Length mm (inch)
C Stem diameter mm (inch)
D EWL mm (inch)
Mass in g (oz)
The featured range of solid carbon fibre styli
ensure the best possible performance of the
RMP400.
It is possible that the featured range of solid
carbon fibre styli may not be suitable for every
RMP400 application and that it may be necessary
to select specialised styli configurations to meet
specific application requirements.
In applications where specialised styli are to be
used, it may be beneficial to reduce the speed of
probing moves. It has been seen in some cases
that specialist styli configurations do not exhibit
the probing characteristics and performance
that would have otherwise been expected and
achieved when using standard styli. Reducing the

speed of the probing move may, in some cases,
improve the performance of the probe.

When selecting components for an application
specific stylus, it is recommended that
a configuration with the least number of
components is chosen. The stylus diameter
should always be as large as possible and the
overall stylus length kept to a minimum. If a stem
with a reduced diameter is required, then it is
recommended that an M4 stem with a short length
and reduced diameter is selected.
