Why You Should Calibrate A Surface Plate - CrossCo

Properly maintaining your surface plate may allow for longer intervals between each calibration, helps you avoid the added cost of relapping, and most importantly ensures the measurements you obtain on the plate are as accurate as possible. Although surface plates appear robust, they are precision instruments and should be treated as such.Why Granite Surface Plate Calibration is Important Keep Granite Surface Plates CalibratedAnother rea granite is the most popular material used for surface plates is because it has a low sensitivity to temperature fluctuations and a hard surface. However, over time, surface plates can wear, which prevents them from being able to make accurate measurements. Thats why its imperative to keep them properly maintained and calibrated regularly. A surface plate that is calibrated will present a What is Surface Plate?
