Grinding ratio Article about grinding ratio by The

Both diamond and CBN abrasives provided grinding ratios (G-ratios) well above those of the SiC abrasive: G for the SiC wheel was about 1, while G-ratios for the superabrasive wheels ranged from about 50 for Borazon 560 CBN to more than 150 for GE MBG-II, a medium-tough diamond material.

Grinding wheel Wikipedia

Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface.

What is grinding ratio (G) Manufacturing

- The grinding ratio is defined as the ratio of the volume of material required to the volume of wheel wear G = (the volume of material required) / (the volume of wheel wear) The value of grinding ratio is usually about 10 to 60 for fine grinding operations like horizontal surface grinding. Whereas, for rough grinding operation, the value

Optimizing grinding and dressing with 'dressing

This means that a grinding wheel dressed at positive speed ratio will be sharper and more open than a wheel dressed at negative speed ratio. Figure 6 Effect of speed ratio on wheel sharpness and dressing. A sharper and open wheel will grind at lower power and force and, therefore, allow for higher material-removal rates, with less chance of
