The structure of the diamond grinding wheel is different from the ordinary abrasive grinding wheel. Generally, it is composed of a diamond abrasive layer, a transition layer and a matrix.
The working layer, also known as the diamond layer, is composed of abrasives, bonding agents and fillers, and is the working part of the grinding wheel. The transition layer, also known as the non-diamond layer, is composed of bonding agent, metal powder and filler. It is the part that firmly connects the diamond layer to the substrate.
The base body is used to receive the abrasive layer and is firmly clamped on the main shaft of the grinder with a flange during use. Generally, metal bond products use steel and alloy steel powder as matrix; resin bond uses aluminum alloy and bakelite as matrix. It is made of aluminum, steel or bakelite, and plays the role of supporting the working layer and clamping abrasive tools. The molding quality of the grinding wheel and the accuracy of the use are closely related to the matrix.
