[0002] Resin grinding wheels are porous bodies made by adding resin binders and core reinforcing rings to abrasives, and are formed by pressing, drying and firing. They are one of the tools for industrial production. During the production process of resin grinding wheels, after adding powdered molding materials into the molding mold, the molding materials need to be further flattened. Then, a hydraulic press is used to apply a certain pressure to make the loose granular molding materials in the mold meet the density requirements, thereby forming a grinding wheel blank with standard size and shape. During the spreading process, resin grinding wheels generally adopt a spreading method in which the mold rotates and the scraper rises and falls. This method is characterized by quantitative feeding, rotation and flattening, and consistent unit weight of grinding wheel products. It is widely used in semi-hot pressing and cold pressing production of resin grinding wheels.
