Effects of Vibration-Assisted Grinding on Wear Behavior of Vitrified ...

The total removal of grinding wheel material includes two main parts. The larger of the two is the result of dressing and truing operation and the other relatively small part is due to the wheel wear which takes place during the actual grinding process. The frequency of dressing and truing operations depends on the cutting conditions, wheel characteristic, etc.

Dressing Technique for Truing Up Diamond Grinding Wheels

When the edges of the grains of a grinding wheel (even one as hard as diamond) have been dulled, the grinding process can suffer. The grinding wheel does not cut as freely, thereby producing more heat in the grind zone. More important, the profile of the grinding wheel wears so that the geometry and precision of the workpiece suffers.
