Investment Casting > Tolerance > Concentricity
A. Concentricity of diameters in a shaft is also a function of straightness. Centers will be concentric within .005" per inch of maximum separation.
B. Centers of I.D. to O.D. will be concentric within .003" per 1⁄2" of wall thickness. This disregards out-of-roundness, and assumes measurements in the same plane If the concentricity is being measured in separate planes, the requirements of paragraph 1 above must be added.
