This would increase the rate of energy generated during the grinding operation, yielding thermal damage of the ground surface and/or higher values of surface roughness. Experiments have confirmed this trend when the fiber content increased from 0% i.e. pure epoxy to 50% during grinding of graphite- epoxy composites. The trend is, however, reversed when the fiber content is increased from 50%

Never grind with a wheel that is designed exclusively for cutting. Such a wheel is not constructed to withstand the side pressure exerted when grinding. Always visually inspect the wheel for possible damage before mounting it on the grinder. If in doubt, don't use it. Don't use a wheel if it has nicks, cracks, or if it has been dropped.
The term grinding burn while grinding is understood as the thermal damage of a ground part caused by an incorrect grinding process. Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heat, the material undergoes a treatment similar to a tempering process. At high enough tensile stresses, caused by the grinding burn at the outer
Grinding operations thus contribute greatly to the quality of the finished workpiece. However, problems can often occur during the grinding process. The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part. Grinding burn occurs when too much heat is channelled into the part. Microcracks and brittle surfaces are often the result. The occurrence …
