In-depth Analysis of Key Advantages of Granite for CMM Platforms / Bases
I. Minimal internal stress, permanent non-deformationNatural granite undergoes natural geological aging over hundreds of millions of years, completely releasing internal stress. Compared to cast iron, cast aluminum, and welded steel structures:It does not exhibit aging creep or long-term stress rebound;The geometric accuracy of the CMM table, crossbeam, and column remains stable for decades;The machine maintains…
