The diamond long life grinding 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. It is made of aluminum, steel or bakelite and functions as a supporting working layer and a chucking tool. The quality of the long life grinding wheel and the accuracy of its use are closely related to the substrate.
