Structure of grinding wheel

The grinding wheel is composed of three main elements (abrasive grain, bond and pores)

Abrasive grain are edges that shave a workpiece, a bond supports the edge, while pores are gaps necessary for removing chips.

The features of the grinding wheel are as follows:
Since the abrasive grain is harder than a workpiece, it can shave hard materials such as quenched steel.

The abrasive grain always have edges with "negative rake angles". As the depth of cut is shallow, the finished workpiece can be fine and attractive.

Multiple edges and high grinding speed enable excellent efficiency even though the depth of cut is shallow.

If an edge becomes round and worn through use, the abrasive grain will drop out and a new edge will appear. This is called "self-sharpening" of abrasive grain.

The quantity of heat produced using the grinding wheel is larger than that produced in cutting. Since the workpiece absorbs most of the heat produced, a large quantity of grinding fluid is neccessary for mechanical grinding.
