Hello friends!
I have a new challenge ahead;
we need to make a few parts that have a drawing callout of grinding after hard anodize (around 0.002-0.003" thick) with a surface finish of N4.
1. parts are tube shaped, around 3" long, 2" diameter. the grinding callout is both ID and OD.
2. one part has a critical datum to which a few true position holes are located to and it represents a 90 degree step to the OD - and the final dimensions will be reached after anodize of course...
3. tolerances of ID and OD are in a tolerance window of 0.0003".
I plan to make the parts on a multitasking machine, complete them with consideration of the anodize so that I will have about 0.0004" to take off the diameters.
Now the question is:
Should I use grinding to do that as the drawing calls for?
Can I turn the coating to size with a PCD/diamond turnin insert and maintain the desired N4 finish using lopping/polishing compund?
Any other thoughs? experiences with hard anodize grinding or sizing?
Thank you for you time and help!
