Usage of Granite Surface Plate

Granite surface plates are precision benchmarking tool that is made of natural stone material. For the testing of the instrumentation, precision tools, mechanical parts, it is the ideal base, especially for high-precision measurement.

Granite surface plate drawn from the underground high-quality rock layer, after hundreds of millions of years of natural aging, the shape is extremely stable, do not worry about the deformation due to conventional temperature difference, granite plate passed rigorous physical testing and selection of granite, crystal fine texture hard, as a result of granite non-metallic materials, no magnetic reaction, no plastic deformation, granite plate has high hardness, so the accuracy is good.
