Granite Tables

High Accuracy, no deformation, good stability, long life, applicable to the machine shop and laboratory measurements.

Mineral composition of pyroxene, plagioclase, biotite, and trace amounts of magnetite, black color, structural precision, after millions of years of aging, even texture, good stability, strength, high hardness, maintain high accuracy under heavy load.

Advantages

High precision, good stability and no deformation to ensure measuring precision at constant temperature;
Freedom from rusting, acid-alkali resistance, no need oiling and difficult to be stained with dust, simple and convenient maintenance;
Excellent rigidity, high hardness, wear resistance and long lifespan;
Tiny scratches or injury on work face can not cause convex and have impact on measurement precision;
There is no magnetization problem to ensure smooth movement without stagnation.
