Pourquoi le granit est-il le matériau idéal pour la base des instruments optiques et des équipements de précision ?
In the field of ultra-precision manufacturing and metrology, equipment bases are not merely simple support structures, but the physi carriers of precision benchmarks—their performance directly determines the imaging resolution of optical systems, the accuracy of parameters in semiconductor inspection, and even the full lifecycle yield of core equipment such as lithogramachines and coordinate measuring machines….
