May 24, 2021 · Truing operations deal with the form or profile of the grinding wheel. When truing a new abrasive wheel, the grinding face is altered to allow the abrasive product to do what it needs to do. Routine truing during the grinding process corrects the wheel profile and compensates for form loss as the wheel breaks down under regular use.

Understanding Grinding Wheel Hardness. The amount of abrasive bond in the grinding wheel determines its grade or hardness. Hardness is dependent on the grit type, the material being ground, the amount of stock removed, and a number of other factors. Hardness is rated from AZ, with "A" being the weakest bond and "Z" being the strongest.

Mar 20, 2018 · 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.
