Being asked to centerless grind a small batch of some small diameter (.110 diameter by 5/8 long) pins. We have a Dedtru centerless that we use quite often for this type of work. Just looking for a wheel recommendation. Will it grind something like 316 stainless? Would you want to grind it before or after heat treat? 40 - 45 R/C. .0002" total tolerance.
