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…

The Impact of Microscopic Surface Quality of Granite Bases on Equipment Performance Microscopic quality mainly includes: roughness, microscopic defects, cleanliness, micro-flatness, material homogeneity, and non-magnetism. Any failure to meet standards will directly affect equipment precision, stability, cleanliness, service life, and yield. I. Roughness Failure (High Ra Value)Impact:Jammed moving parts, rapid wearGuide rails, slides, and mounting…

Why are granite bases almost universally used when retrofitting/upgrading laser equipment?When upgrading laser equi(fiber laser cutting machines, marking machines, welding machines, picosecond/femtosecond lasers, precision inspection laser equipment) or retrofitting old machines,r 95% of the time, cast iron, steel plate, or profile bases are directly replaced with granite. There are 8 core reasons, all directly addressing…

La micro-qualité de la surface des bases en granit des équipements semi-conducteurs, caractérisée par une rugosité à l'échelle nanométrique, l'absence de micro-défauts, une très grande propreté, des propriétés non magnétiques et sans contamination, ainsi qu'une micro-morphologie uniforme, détermine directement le rendement des plaquettes et la stabilité à long terme de l'équipement. I. Rugosité de surface (indicateur de base) Surfaces de travail (repères / guides / surfaces sous vide) : Ra ≤ 0,01-0,05 μm (10-50 nm) ; Machines de lithographie haut de gamme / plateformes d'inspection....
