All the grinding heads utilise the principle of line contact between abrasive and stone, to ensure a faster grinding action. The most common type of grinding heads in use today are the oscillating heads (or the rocking heads) and satellite heads (or planetary heads). The rocking heads consist of 2, 4 or 6 rotating abrasives, which are made to ...

When using vitrified or metal-bonded grinding wheels, these resistance forces lead to fracturing of the abrasive grain from the bond. In the case of organic- and resin-bonded wheels, the heat produced from the grinding interaction releases dull abrasive grains over time, exposing the new sharper grain beneath it.
