It is a cutting tool in which millions of microscopic abrasive grains are bond together.

Here, each abrasive grain acts like a spiky tool.

The abrasive grains are held together in the porous structure of the grinding wheel by a bonding substance (bond).

The grains lose their sharpness and are to be regularly removed to allow fresh new grains to come forward.

Bond material - Due to which, abrasive grains are held together.

Apart from grains and bond, the porous construction of the wheel is an important part.

Accuracy of the profile : Very stringent profiles tolerances.

Grinding Cracks : Grinding cracks are absolutely not acceptable -Various Test Methods -Nital test, BN Value.
