Manufacturing method for grinding wheel

The invention discloses a manufacturing method for a grinding wheel and belongs to the technical field of grinding wheel manufacturing. The manufacturing method comprises the following steps that firstly, metal powder mixed materials containing an abrasive serve as raw materials, and a grinding wheel blank is made through an injection molding procedure; then the grinding wheel blank is subjected to the procedures of debonding and sintering sequentially; and finally, a finished product is obtained through electric spark finishing. Uniformity of inner materials in the grinding wheel blank made through the manufacturing method is good, after the finished product is sintered, the density is high, breaking strength is high, subsequent debonding, sintering and electric spark finishing are convenient, and finally the grinding wheel of which both the strength and grinding sharpness reach the use requirements is obtained.
