Granite Surface Plate Performance

Granite surface plate is made of natural stone materials, belongs to precision benchmarking tools, for the instrumentation, precision tools, mechanical parts inspection, it is the ideal datum, especially granite plate is used for high-precision measurement. 

Granite slabs are based on high-quality rock layers in the ground. Their shapes are extremely stable after hundreds of millions of years of natural aging, do not worry about the deformation due to conventional temperature difference.

Granite surface plate has high hardness, so the accuracy is good, granite platform has many advantages, such as high precision, no rust, acid, non-magnetic, the same type, good wear resistance and so on. Granite plate can remain stable at heavy loads and at normal temperatures.
