Granite squares are ideal reference surfaces for testing instruments, precision tools, and machined parts. They are particularly suited for high-precision measurement. Made from underground rock layers, granite squares have been naturally aged for millions of years, resulting in an extremely stable form. They are not susceptible to deformation due to typical temperature fluctuations. Granite Square Performance: Granite, 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 Precision: Even if struck by heavy objects during use, granite squares will only produce a few grains of stone chips. Granite squares offer superior precision measurement reference components made from cast iron and steel, achieving high and stable accuracy. Granite squares: Made from granite, they possess a black luster, precise structure, and uniform texture, offering excellent stability, strength, and hardness. The working surface is scraped or precision-ground, making them suitable for measuring workpiece straightness and perpendicularity, as well as for equipment installation.
