A cast iron surface plate is a flat reference plane used in manufacturing and inspection processes to provide a solid measurement foundation. Its durability and accuracy are essential for precision measurements.
When choosing a precision surface plate, the options often boil down to cast iron and granite. Both materials have vocal advocates in the metrology field, but which one truly delivers on accuracy, durability, and reliability? Users frequently ask about the longevity of each option, the precision ...
Cast Iron is the most commonly used material in manufacturing, machine shops, and shop floor as it provides the best surface plates over the other materials.
Granite surface plate is a natural stone material made of precision reference measurement tools, for the instrumentation, precision tools, mechanical castings inspection, are the ideal datum.
Granite is considered the best material for surface plates because its properties (e.g., surface hardness, low thermal expansion, no rust or corrosion, little warping, longer wear life) result in very accurate, stable, and precise surfaces
