This is a very common question we get very often. Our quick answer is that in most cases .012 on diameter and .003 to .0050 on faces/shoulders is optimal.

However, there are some instances that the answer to “How Much Stock
Should I Leave for Grinding?” is not as straight forward.

There are several things to consider when answering this question:

  • Material of the workpiece.
  • Was the workpiece heat treated?
  • What kind of heat treatment was done?
  • Was the workpiece warped during heat treatment?
  • Was the workpiece straightened and stress relieved?
  • Is the material prone to cracks or burning easily while grinding?
  • The type of grinding wheel that will be used to grind the workpiece.
  • Required surface finish.
  • Lot size
  • Material’s grindability index.
  • Was there any machining mismatch between operations?
  • Ratio of stock on diameter and shoulder
  • corner radius
