precision surface plate
Granite surface plates—commonly but inaccurately referred to as “marble platforms”—serve as primary precision reference standards in metrology, widely employed in precision engineering, instrumentation, electronics manufacturing, and scientific research laboratories. Fabricated from naturally aged, geologically stable granite with low thermal expansion and high dimensional stability, these plates undergo rigorous multi-stage lapping and calibration processes to achieve stringent flatness tolerances (typically ≤0.5 μm per 100 mm), ensuring long-term metrological reliability and traceable measurement accuracy.

CNC GRANITE BASE
A granite surface plate is a workbench or datum plane made of natural granite with an extremely flat surface. It is mainly used as a reference plane for precision measurement, providing a stable and accurate reference origin for various measuring tools (such as height gauges, micrometers, coordinate measuring machines (CMMs), etc.). In the CNC (Computer Numerical Control) machine tool and precision machinery industries, it is also often used as a core component for machine tool bases, guide rails or worktables.
