PRECISION GRANITE
On Site Services (Calibration) Ltd are proud to offer a range of precision granite products that are manufactured using high quality, fine grained black granite. These are precision finished by hand to ensure they are of the highest quality.
There are many advantages to using fine grained black granite in all aspects of engineering and measurement, from shop floor and work holding to accurate inspection and calibration. In a forever advancing industry it is important that reliance can be placed on all measurements taken. Our precision lapped granite products are produced to the highest accuracy to aid in this confidence of measurement.
The main advantages of introducing and using granite measuring equipment are:
-
Does not rust.
-
Non-electrically conducting.
-
Less susceptible to burrs.
-
Does not directly contribute towards “metal to metal” cross contamination.
-
Non-magnetic.
-
Not as susceptible to environmental changes such as humidity and temperature.
We are also able to offer bespoke services on all granite products from large surface tables with multiple threaded inserts to individual granite artefacts as per customer drawings. So if you have any special requirements, please do not hesitate to contact us. Our skilled team are on hand to answer any questions.
