Granite square boxes are used for testing instruments, precision tools, and mechanical parts. Made from high-quality underground rock layers, granite square boxes have been naturally aged for millions of years, resulting in an extremely stable shape and no risk of deformation due to typical temperature fluctuations.
Granite Square Box Performance: Granite material, carefully selected and subjected to rigorous physical testing, boasts fine crystals and a hard texture. Because granite is a non-metallic material, it exhibits no magnetic properties and exhibits no plastic deformation. Its high hardness ensures excellent precision retention.
Granite Square Box Precision: Even with heavy impacts, granite square boxes will only produce a few grains of stone chips during use. Granite square boxes surpass precision measuring reference components made of high-quality cast iron and steel, achieving high and stable accuracy.
Granite square boxes: Made of granite, they possess a black luster, precise structure, uniform texture, excellent stability, high strength, and high hardness. The working surface is scraped or precision ground, making them suitable for measuring workpiece straightness and perpendicularity, as well as for equipment installation.
Granite square boxes: Guide rails and precision workpieces with flatness and verticality. Our granite square boxes offer advantages such as high precision, rust resistance, acid and alkali resistance, non-magnetization, deformation resistance, and excellent wear resistance. They can maintain stability under heavy loads and at normal temperatures.
