Correct option is C
In a grinding wheel, concentration refers to the amount of super abrasive grit present. The concentration is typically measured as the volume percentage of abrasive grains in the wheel. Higher concentration levels indicate a greater amount of abrasive material, which affects the cutting efficiency and durability of the grinding wheel. The concentration is crucial in determining the wheel's performance, especially when working with hard materials.
For superabrasive grinding wheels, which use abrasives like
diamond or
CBN (Cubic Boron Nitride), the concentration of these materials is crucial for determining the wheel's performance. Higher concentrations of abrasive grit usually result in a more aggressive cutting action, but they may also lead to a faster wear rate of the wheel.
