Thanks for your thoughts. I have purchased some pin gages and they are what I am looking for, but I don't have a way to verify if they are flat on the bottom because they are so small. I wonder how they manufacture them because that same process would probabaly work for me.
Greetings,
I need to manufacture a pin that is much like a pin gage used for measuring. The pins need to be about 3” long and vary in diameter from 1mm down to .2mm. The ends of the pins must be perfectly flat so that the pin would balance if stood on end.
What material(s) and manufacturing...
