grizzly surface plate
Granite flat surface plate calibration is the only sure way to know that you are working with a level surface and can expect accurate workmanship when the surface plate is in use. Surface plates wear over time and must be properly maintained to ensure flatness and continued precision measurement.
Granite flat surface plate performed by FORTUNE are A2LA accredited and the equipment used by our technicians has a NIST-traceable calibration. A Calibration Certificate is generated following service that will show grade requirements, “as found” and “as left” conditions and a detailed explanation of the work completed to restore flatness. We will send you a reminder notice when it is time for recalibration, based on the frequency you set.
Measurement during granite flat surface table calibration includes checking for wear and deviation from the grade requirements. In many cases, proper resurfacing can bring the surface of the plate back within flatness tolerances. Flatness tolerances for standard grade surface plates AA, A and B are defined in federal specification GGG-P-463c.
