Concentricity is the degree to which two or more circles or cylinders share the same center. It is an important measurement in many manufacturing and engineering applications, as it can affect the performance and reliability of a product. There are a number of different ways to check concentricity, depending on the specific application.
One common method is to use a dial indicator. A dial indicator is a precision measuring instrument that can be used to measure the displacement of a surface. To check concentricity, a dial indicator is mounted on a fixed surface and the object being measured is rotated. The dial indicator will then measure the variation in the distance between the object and the fixed surface.
