Styli recommendations for OSP60
SPRINT™ scanning probes

The SPRINT™ on-machine scanning system can be used with a range of
SPRINT-specific styli to suit individual application requirements, all of which
complement the enhanced capability provided by the OSP60 SPRINT probe.

SPRINT-specific styli are available in two ranges: the SPRINT standard range, which is suitable for the majority of applications,
and the SPRINT calibrated range (UKAS certified), which is designed for the most demanding applications. Both ranges
incorporate a number of design elements which offer improved metrology performance for machine tool scanning applications.

SPRINT standard range

During scanning the stylus is constantly deflected, so the
ceramic stem has been designed to be narrow and therefore
tightly control all squareness tolerances. This ensures that
even when measuring a part with vertical surfaces, such as on
prismatic parts, the risk of the stylus shank contacting the part
before the stylus tip is minimised.

SPRINT calibrated range

In the variable temperature environment typical of a machine
tool, the dimensional variation of the calibration sphere,
compared with the machine structure, can degrade the
performance of the measurement system. In the highest
accuracy applications, this contribution to the overall system
measurement uncertainty can be significant.

To ensure the highest possible measurement accuracy in all
measurement conditions, the ball on each stylus within the
SPRINT calibrated range is measured and UKAS certified.
The exact ball diameter is engraved onto the stylus holder, so
that this highly accurate value can be applied during probe
calibration as an absolute reference.
