Granite Surface Plate Grade 0, P300300-0, 300 x 300x 65mm with stand. Conforms to BS 817 1988. With UKAS Calibration Certificate. Accuracy .002mm

Supplied with MQS UKAS Certificate of Calibration We are offering high-quality black granite, known for its superior density of approximately 3100 kg/m³. surface plate made from fine-grained black granite. This material has many advantages compared to cast iron in this application, such as being non-magnetic, rustless, twice as hard, non-burr-forming and not prone to stickiness. A granite surface plate is an essential investment for laboratories and test facilities For reliable and consistent measurement results, a granite surface plate is crucial. As the surface is a smooth and stable plane, it enables instruments to be carefully manipulated. They are also used in set-up of tooling, production and inspection. The main advantages of granite surface plates are: Non-reflective Resistant to chemicals and corrosion Low coefficient of expansion compared with cart iron, so less affected by temperature changes Naturally rigid and hard-wearing The plane of the surface is unaffected if scratched Will not rust Non-magnetic Easy to clean and maintain Calibration and resurfacing can be done onsite Suitable for drilling for threaded support inserts High vibration damping Carriage is Extra Ex Coventry Specification Dimensions L x W x H: 300 x 300 x 65mm Delivered: Without Stand Standard Grade 0 BS 817 1988
