Hello all, I've been given the task of researching a concept of mass production (possibly tons per year) of the pin that has double radius on tapered ends. The initial though was to use a couple of angled grinding wheels and some rocking motion as pins are fed thru but the more I think about it, it make less and less sense to me. So I thought, what if someone out there encountered something similar in their career and can share with me an idea or give me some clues or insights. Anything would be greatly appreciated. I attached a screenshot of a pin, it's a little over inch long and I exaggerated the radiuses to make them visible. On the real pin they're much bigger and look like flat surfaces. Thanks!
