What is the difference between diamond grinding wheels and ordinary abrasive grinding wheels

2020-05-04 1270
A circular solid grinding tool with a central through hole made from diamond abrasive as the raw material, using metal powder, resin powder, ceramics, and electroplating metal as the bonding agent, is called a diamond grinding wheel (alloy grinding wheel).
Diamond grinding wheels are different in structure from ordinary abrasive wheels, generally consisting of a diamond abrasive layer, a transition layer, and a substrate.

The working layer, also known as the diamond layer, is composed of abrasives, binders, and fillers and is the working part of the grinding wheel. The transition layer, also known as the non diamond layer, is composed of a binder, metal powder, and filler, and is the part that firmly connects the diamond layer to the substrate.
The substrate is used to receive the abrasive layer and is firmly clamped onto the grinding machine spindle with a flange during use. Generally, metal bonding products use steel and alloy steel powder as the substrate; The resin binder uses aluminum alloy and bakelite as the substrate. It is processed from aluminum, steel, or bakelite and serves as a support for the working layer and for clamping and grinding tools. The quality of grinding wheel formation and the unevenness of usage accuracy are closely related to the substrate.
