[Me...] Posted October 6, 2020 Share Posted October 6, 2020 Have any of you ever dealt with ID grinding/Honing/Machining after Hard Coat Anodize? Our company is doing it to a few parts due to different anodize specs for separate features and so far it is not working at all. I'm curious as to why our Customer's engineers would require a 16 RA on a finished Hard Coat Anodized surface to begin with but that's just me... Wouldn't removing the anodize by machining/grinding or honing defeat the entire purpose of the anodize itself? Link to comment Share on other sites More sharing options...
[Ri...] Posted May 1, 2021 Share Posted May 1, 2021 Hard coat anodize is an impregnation anodize. This means, as an example, an anodize requirement of 0.0060 (inch) will impregnate the material approximately 50%. Thus grinding is only remove the surface build up and still leaving anodize properties within the material itself. Typically, grinding doesn't remove all of the surface build up. Hard Coat Anodize is called Anodic Anodize. Link to comment Share on other sites More sharing options...
