Large Metal Surface Plate Calibration

Across industries, metal surface plates play a crucial role in allowing their users to make precise and accurate measurements by serving as a trustworthy reference point, particularly because of their flatness. However, continual use and environmental conditions can create wear on the surface plates, impacting the flatness. Calibration is essential to ensure the surface plate remains the tool it should be, but traditional methods of calibration, such as electronic levels, are difficult, time-consuming, especially on large metal plates and liable to miss wear in large parts of the surface plate due to the limitations of the Moody Method.  Our Grid Method gives you the flexibility to measure as large a surface or small a surface as you want to a high degree of accuracy.

The L-740 Ultra-Precision Flatness Measuring System offers a much faster and more precise way to check the flatness and level of lower-grade metal surface plates:

  • A continuously rotating laser creates a reference plane from which to measure the surface plate, thereby allowing the entire plate to be compared to a plane with a flatness of 0.25 arc second (0.000015 in/ft or 0.0013 mm/m).
  • Wireless A-1520-2.4ZB targets with a resolution of .00001 in. (0.00025 mm) allow for easy set-up and positioning and the use of multiple targets, easing the process of measuring even the biggest surface plates.
  • Allows the Grid Method data taking, which measures more points on the surface plate.
  • Versatile Windows-based software uses the Moody or Grid methods, records and analyzes data, and runs on any Windows laptop/tablet.
  • Surface plates do not need to be level to measure the flatness with the L-740, saving time on calibrations.
