Structure
The volume ratio of abrasive grains to the total volume of a grinding wheel
is called the "percentage of grain."
The density of the structure depends upon this percentage.
Structures 0 to 4 are referred to as dense, 5 to 9 are referred to as medium, and
10 to 14 are referred to as coarse.
