Calibration and Resurfacing of Granite Surface plates
At Optimal Calibration, three precision instruments are used in conjunction with one another to determine the accuracy of a given surface plate. The Repeat-O-Meter is the instrument that is used to check the repeatability, or small wear spots that occur from normal everyday use. These small wear spots are often the result of the constant sliding of your parts and/or measuring gages along the surface of your granite plate. Both the Planekator and Autocollimator are the instruments used to check the overall flatness or corner to corner flatness of a surface plate. Using these particular instruments the technicians at Optimal Calibration are able to determine the profile of a given surface plate. According to Federal Specifications GGG-P-463c, each surface plate must pass both the repeatability and overall flatness test in order to be legally certified. The allowed tolerance of a surface plate is defined by its size and grade.
