What is G-Ratio? Grinding Operations Explained
14/10/2022· When the grinding wheel removes a large amount of material from the workpiece with little wheel wear, the G-ratio will be high. If the wheel is soft and does not remove a lot of material but the wheel wear is high, the wheel will have a G-ratio that is low. This is common with difficult-to-grind (DTG materials).

Grinding wheel Wikipedia
Density is the ratio of bond and abrasive to air space. A less-dense wheel will cut freely, and has a large effect on surface finish. It is also able to take a deeper or wider cut with less coolant, as the chip clearance on the wheel is greater.

5 Grinding Considerations for Improving Surface Finish
20/8/2021· When the overlap ratio increases, the dresser hits the same grit on the wheel more times, creating a fine topography on the wheel surface. This makes the wheel face dull and closed, resulting in a finer surface finish on the workpiece. However, care must be taken to ensure the wheel face is not too closed after very fine dressing. A closed wheel face can result in
