I am hoping someone can help me out here.
I have some aluminum parts that I had run by a CNC shop. They used a forming knulring tool to make a diamond knurl pattern. It looks nice. However After having it anodized there are small particles in the grooves which are coming off revealing bare aluminum. It's obvious that the particles have been mashed into the grooved during forming regardless of the fact that flood coolant was used.
What I'd like to know is what can be done to eliminate or at least minimize this problem? I did use a scrub brush on the parts prior to plating but apparently it didn't get enough out. Maybe the bristles weren't small enough to get into the grooves? I tried taking pictures to show but the camera just doesn't capture what the naked eye easily sees.
I had a thought that an ultrsonic cleaner might help loosen the particles but I can't get anyone on the phone from one of the ultrsonic cleaner makers to ask. I keep getting voice mails.
If anyone has experience or tips I sure would appreciate it.
Thanks!
