GRINDING FEEDS AND SPEEDS

Most cylindrical grinding machines offer a rather wide range of work rotation speeds, table traverse speeds, feed rates, and, sometimes, different wheel speeds as well. The proper selection of these variables, in combination with the choice of the grinding wheel, has a great bearing on the results and the economy of the grinding operation.

5 Grinding Considerations for Improving Surface Finish ...

Jan 26, 2021  In applications where the cycle time is not critical, reducing the feed rate might be a good option for improving the workpiece surface finish. When the wheel speed is increased and the depth of cut and feed rate are reduced, the wheel can become dull. This increases the chance of thermal damage to the workpiece and can increase grinding forces.
