Abstract

The invention discloses a diamond grinding wheel and a preparation method thereof, and belongs to the field of hardware tools. The diamond grinding wheel comprises a diamond base material, a resin adhesive, a ceramic adhesive, carbon black, a toughening agent and anhydrous ethanol. The preparation method of the diamond grinding wheel comprises the following steps that firstly, a mixed adhesive is obtained by mixing the resin adhesive and the ceramic adhesive; after the diamond base material is added and stirred, then the carbon black, the toughening agent and the anhydrous ethanol are added, stirred and mixed, and a grinding wheel material is obtained; a grinding wheel green body is obtained through compression molding in a grinding wheel mold; and after sinter molding in a sintering furnace and natural cooling, the diamond grinding wheel is obtained. The diamond grinding wheel and the preparation method thereof have the beneficial effects that the diamond grinding wheel has good grinding effect, high strength, and better impact resistance at the same time.

Description

technical field [0001] The invention relates to a diamond grinding wheel and a preparation method thereof, belonging to the field of hardware tools. Background technique [0002] Diamond grinding wheels use diamond abrasives as raw materials, and use metal powder, resin powder, ceramics and electroplated metals as binders respectively. The circular bonded abrasives with a through hole in the center are called diamond grinding wheels (alloy grinding wheels). [0003] Diamond grinding wheels are divided into metal bond diamond grinding wheels, resin bond diamond grinding wheels and vitrified bond diamond grinding wheels. Among them, the resin bonded diamond grinding wheel is made of powdered artificial diamond as the abrasive, resin powder or resin liquid as the binder, adding appropriate filling materials, and is made through preparation, mixing, molding, curing, machining and other processes. It is a kind of diamond grinding tool with certain geometric shape and applicable ...
