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
