Measuring instruments
Measuring instruments are essential in many industrial sectors and quality control laboratories. In our catalogue you will find a wide range of precision instruments made from high quality black granite, designed to guarantee reliable and long-lasting measurements.
A complete range of granite measuring instruments
All our instruments are made with high quality materials and dimensional stability, ensuring low thermal expansion and optimal resistance to chemical and environmental agents.
Black granite is a reference material for those who demand the highest metrological precision. Thanks to its technical characteristics, its compact structure that guarantees a uniform density, results in perfectly stable surfaces and unalterable over time.
The extremely low thermal expansion coefficient minimizes dimensional changes even in the presence of temperature fluctuations, while the high vibration damping capacity ensures repeatability and measurement accuracy.
The hardness and natural resistance to corrosion and wear, preserve the quality and flatness of the contact surfaces, maintaining micrometric tolerances throughout the service life of the instrument and always repistinabili with a revision intervention.
In summary, granite combines stability, precision and durability, making it an ideal material for countertops, control benches and structural components of high-performance measuring machines.
To achieve the highest metrological precision, explore our range of ceramic alumina and silicon carbide measuring instruments: advanced solutions for those looking for maximum reliability and superior performance in workshop and laboratory.
Our selection of granite measuring instruments includes:
Feedback plans
Available in different degrees of precision for every control and calibration requirement
Lines of granite
both linear and plane-parallel, to check alignments and linearity with the utmost precision
Control teams
Supplied in two degrees of precision, they are ideal as a geometric reference to check the perpendicularity between surfaces or parts. It is indispensable for calibrating machine tools, testing measuring equipment and certifying components in workshop or metrological laboratory environments.
Control parallelepipeds
indispensable tools for checking flatness, perpendicularity, orthogonality, parallelism and cylindricity, such as reference thicknesses for machine set-up or comparator support, offer wide and opposite surfaces that are perfectly planar and parallel, Easy to pair with matching plans or test components.
Cubes, prisms and cylinders
Used for the quick check of orthogonality on three axes (X-Y-Z), positioning and locking workpieces during precision machining, can be supplied with 2, 4 or 6 flat and parallel machined faces.
V-prisms at 90°
Essential for the centring and alignment of shafts or tubes for concentricity and roundness measurements, they have a 90° structure that accommodates cylindrical bodies guaranteeing stable support and well-defined axis with respect to the work surface.
Reference cylinders
Useful for checks such as calibration of diameters, check of spindles and rotary tables, coaxial and run-out tests, thanks to a rotational symmetry provide an ideal axis and a continuous surface to check eccentricities and circular deformations.
