Why is high-quality precision granite the preferred material for the worktable of a high-precision coordinate measuring machine?
High-Precision CMM WorktableWhy Premium Precision Granite (Jinan Qing) is the First ChoiceExtremely long-term dimensionay, virtually permanent deformation resistanceNatural granite has undergone natural aging over hundreds of millions of years, completely releasing internal stresses. Unlike cast iron or steel, it does not cr, deform, or age over time, perfectly matching the high-precision reference requirements of CMMs.Extremely…
