Grain size or Grit size
Grain or grit size is the actual size of the abrasive grain. The abrasive particles are graded by passing through sieves of various sizes. They are indicated by a number ranging from 10 (coarse) up to 600 (very fine). Generally, a fine grit wheel gives a smooth surface and is used for finishing work.
The number indicating the size of the grit represents the number of openings in the sieve used to size the grain. The larger the grit size number, the finer the grit.
If the grit size of the grinding wheel is large, it indicates finer grit means smaller grain size.

Explanation:

When a grinding wheel is manufactured, abrasive grains are bonded together with a matrix material. The abrasive grains are the cutting tools that remove material from the workpiece. The size of the abrasive grains determines the coarseness or fineness of the grinding action.

If the grit size of the grinding wheel is large, it indicates that the abrasive grain size is small. This means that there are more abrasive grains per unit of area, resulting in a finer grinding action. Conversely, if the grit size is small, it indicates that the abrasive grain size is large, resulting in a coarser grinding action.

Therefore, the grit size of a grinding wheel is directly related to the size of the abrasive grains in the wheel.

Importance:

The grit size of a grinding wheel is an important factor to consider when choosing a wheel for a particular grinding application. A finer grit size is suitable for finishing and polishing operations, while a coarser grit size is better for rough grinding and material removal.

Conclusion:

In conclusion, the grit size of a grinding wheel indicates the size of the abrasive grains in the wheel. A large grit size indicates a small abrasive grain size, while a small grit size indicates a large abrasive grain size. The grit size is an important factor to consider when choosing a grinding wheel for a specific application.
