Granite V-shaped frames are made from high-quality natural granite, processed through machining and finely polished. They feature a glossy black finish, a dense and uniform structure, and excellent stability and strength. They are highly hard and wear-resistant, offering the following advantages: long-lasting accuracy, resistance to acids and alkalis, resistance to rust, resistance to magnetism, and resistance to deformation. They maintain stable performance under heavy loads and at room temperature.
This measuring tool, using natural stone as a reference surface, is widely used for testing and calibration of instruments, measuring tools, and precision mechanical parts, and is particularly suitable for high-precision measurement applications.
Granite V-shaped frames are sourced from deep-seated rock and, after years of geological aging, have an extremely stable internal structure that resists deformation due to daily temperature fluctuations. The raw material undergoes rigorous physical property testing and screening, resulting in fine, hard crystal grains. Because granite is a non-metallic material, it is immune to magnetism and plastic deformation. Its high hardness ensures that measurement accuracy is maintained over time. Even accidental impacts during operation typically result in only minor chipping, which does not affect overall performance.
Compared to traditional cast iron or steel measuring datums, granite V-stands offer higher and more stable accuracy. Our marble V-stands maintain their accuracy even after being left for over a year, demonstrating excellent stability and reliability.
