Structural characteristics of the grinding wheel
The structure of the grinding wheel. The grinding wheel is a tool made of a round cake or a ring made of abrasive and a bonding agent, and the workpiece is ground by rotation. The conventional grinding wheel is a round cake made of alumina abrasive and a bonding agent. The shape of the grinding wheel, we call it the traditional grinding wheel.

It constitutes the three major elements of the grinding wheel. Abrasives are the granules that directly grind the workpiece; the binder is used to produce the bonding force between the abrasive granules, maintain the force, and make the grinding wheel safely rotate at a certain speed; the stomata is the gap between the abrasive and the bonding agent, Helps remove debris and maintain a grinding effect.
For example, the diamond wheel structure generally consists of a working layer, a base body, and a transition layer. The working layer, also known as the diamond layer, consists of abrasives, binders and fillers and is the working part of the grinding wheel. The transition layer, also called a non-diamond layer, consists of a binder, a metal powder, and a filler, and is a portion that firmly bonds the diamond layer to the substrate.

The base body is used to receive the abrasive layer and is firmly clamped to the grinding machine spindle by a flange during use. Generally, the metal bond product is selected from steel and alloy steel powder as the matrix; the resin bond is selected from aluminum alloy and bakelite as the matrix. The quality of the grinding wheel and the accuracy of its use are closely related to the substrate.
