Granite vs. Cast Iron Base — Comprehensive Vibration Control ComparisonI. Core Vibration-Related Material ParametersTablePerformance Indicator Natural Granite (Jinan Green / Black Granite) Gray Cast Iron HT250/HT300 Impact on Vibration ReductionDamping Coefficient (Core of Vibration Reduction) 0.06–0.12 0.02–0.03 Granite damping is 3–4 times that of cast iron, vibration decay is much fasterElastic Modulus Approx. 50GPa 100–140GPa…

Full-field Applications of Granite Machine Tool Bases (Granite Bases)Relying on six core characteristics—low linear expansion, strong vibration absorption, non-magnetic, rust-proof, zero internal stress, and high flatness—granite machine tool bases are exclusively used for micron/nanometer-level high-precision equipment. They are not suitable for general machine tools subject to heavy cutting impacts. They are divided into six major…
