Granite Precision Measuring Tools (Granite Precision Gauges)Granite precision measuring tools are high-precision reference measuring instruments made from natural black granite (mainly Jinan Qing and Mount Tai Qing) through precision grinding. They replace cast iron gauges and are widely used in precision machining, metrology inspection, CMMs, semiconductors, and laboratory calibration. Their core advantages are stable precision,…

Core Applications of Granite Precision Gauges in IndustryGranite gauges (mainly made of black natural granite such as Jinan Green and Taishan Green, including square rulers, straight edges, square blocks, surface plates, V-blocks, bases, etc.), with their characteristics of high precision, no deformation, no rust, no magnetization, and vibration damping stability, are the core reference tools…
