What is a Granite Flat Surface Plate?

A granite flat surface plate is a flat, solid piece of granite that serves as a reference plane for dimensional measurement. Manufactured from high-grade granite, these plates exhibit exceptional rigidity, durability, and stability, making them ideal for use in metrology. Their surface is finished to a precision flatness that allows for accurate setups in a variety of measurement applications.

Key Characteristics of Granite Flat Surface Plates

The characteristics of granite flat surface plates set them apart from other types of measurement surfaces. Here are some notable features:

  • Durability and Stability: Granite is resistant to wear and tear, maintaining its flatness over time. This makes it an ideal choice for environments that require consistent measurement accuracy.

  • Non-Magnetic: Unlike metal plates, granite does not attract ferrous materials, which helps prevent interference during measurements, ensuring the integrity of the results.

  • Thermal Stability: Granite maintains its dimensional stability across a range of temperatures, which is critical for precision measurements in varying conditions.

  • Impermeability: The non-porous nature of granite resists chemical absorption, ensuring that oil or other substances do not compromise the integrity of measurements.
