The world’s first strain gauge
based inspection probe for
grinding machines, using
Renishaw’s patented Rengage™
technology
The Renishaw MP250 is an ultra compact touch probe for grinding
machines that sets new standards for the precision measurement of
3D part geometries, whilst offering all the standard probing benefits of
reduced set-up times, reduced scrap and improved process control.
The MP250 uses a hard-wired connection to the machine control via the
specially designed HSI interface.
It offers a truly unrivalled combination of size, accuracy, reliability and
robustness that will benefit its users.
Key benefits
High accuracy
Patented RengageTM strain gauge technology with
ultra-low pretravel variation provides high accuracy, even
when the application requires long styli. This allows
sub-micron 3D performance on a range of applications which
demａnd high precision measurement such as contoured
surfaces, for example gear teeth and cutting tools. Probe
calibration times are reduced compared to standard probes.
Highly repeatable
Improved repeatability in all probing directions compared to
standard probes.
Ultra compact
Measuring only Ø25 mm x 40 mm long, the MP250 is ideal
for grinding machine applications with restricted space.
Robust and reliable
Renishaw's MP250 sets new standards for reliability and is
designed to resist the harsh machine conditions.
The MP250 probe is sealed for use within the grinding
machine’s hostile environment, where it is subject to
particle-laden coolant. The diaphragm material is resistant
to coolants and elevated temperatures.
The MP250 offers resistance to shock and false triggering
through the use of digital filtering.
Solid-state strain gauge technology reduces the effects of
mechanical wear resulting in improved life time compared
to traditional probes.
Innovations
The MP250 successfully combines the miniaturisation
of the popular LP2 with the high accuracy Rengage™
technology of the MP700 and OMP400, which has been
proven in thousands of machine tool applications
worldwide.
