Description

technical field [0001] The invention belongs to the technical field of high-efficiency grinding processing tools for engineering ceramics, and in particular relates to a double-abrasive electroplated diamond grinding wheel for machining the outer circle of engineering ceramics. Background technique [0002] At present, in the engineering ceramics processing industry, the conventional processing of the outer cylindrical surface of engineering ceramics is still the traditional parallel grinding wheel reciprocating grinding. Generally, the shape of the parallel grinding wheel is circular. During processing, the surface of the inner hole on the grinding wheel is matched with the motor spindle. The thread on the end of the motor shaft provides clamping positioning. The diamond layer abrasive on the surface of the parallel grinding wheel is generally a single type of abrasive, that is, the particle size of the abrasive grains on the circumference of the grinding wheel and the end ...
