I have 2 little straight pins that need to get centerless ground down to size on the OD.
One is .040 +/- .0002 and the other is .0625 +/- .0002
Both parts are made from 303 SS and OAL = .525
We run them a little oversize on our Swiss to somewhere around .004/.005 oversize on the OD.
Qty = 750
Some say grind the bar down to size and run it, but we can't run bar that small in our machines.
Some say you should be able to hold that tolerance on a Swiss, but it just doesn't happen on these jobs.
I'm in so California and can't find a grinder who can confidently quote or do the job.
Can anyone provide info on shops that specialize or can easily do this type of work. Someone that you have first hand experience with is ideal.
Any input is greatly appreciated.
Thanks.
