Measuring hard anodise thickness concentricity
January 27, 2010
I am a UK Manufacturing engineer, on assignment in Indonesia where my Company, has a Joint Venture with an Indonesian company, manufacturing components for aircraft wing control surfaces. We have a hard anodizing process line here and have a new component that requires a hard anodised, through bore, 12,825 mm diameter by 56 mm long in a prismatic block.
The bore has a thickness requirement of nominally 50 microns which, after honing, must be concentric to the original aluminium bore within +2 to -5 microns per surface (on radius).
My customer requires that we demonstrate, on an ongoing basis, adherence to this requirement
My question is, does anyone know of a measuring instrument or method on the market (Eddy Current, Ultrasonic etc,etc), other than direct measurement (on a CMM for example), that could measure this degree of concentricity accuracy, in a bore this small ?
