Granite Square Ruler

The granite right angle ruler is suitable for detecting verticality. The plane accuracy standard is GB6092-85, and the verticality standard is GB6092-85. To reduce weight and facilitate processing, weight reduction holes have been added. The tolerance on the side is 0.02. The granite right angle ruler is mainly used for measuring the flatness, verticality, and straightness of workpieces. The main mineral components of granite square ruler are plagioclase, plagioclase, small amounts of olivine, biotite, and trace amounts of magnetite. It has a black color and structural code. After billions of years of aging, it has a uniform texture, good stability, high strength, and high hardness, and can maintain high accuracy under heavy loads. The granite square is suitable for industrial production and laboratory measurement work. Specification of granite square ruler: (Special specifications need to be customized).
