Abstract

The invention relates to a resin grinding wheel and a preparation method thereof, belonging to the technical field of resin grinding wheel production. The raw materials of the resin grinding wheel include abrasive, phenolic resin liquid, phenolic resin powder, cryolite, pyrite, titanium dioxide, floating beads, alkaline earth oxide ,lubricant. The resin grinding wheel, through the synergistic effect between the raw materials, makes the resin grinding wheel have a higher workpiece wear and grinding ratio under the condition of the polished surface of the workpiece and no black spots, and also has a lower grinding wheel loss. The service life of the resin grinding wheel is improved, and the resin grinding wheel also has good compressive strength and hardness, so that the resin grinding wheel has a good use effect. The preparation method of the resin grinding wheel, by adding a circular magnetic field, twice machine pressing, and twice curing, the raw materials are fully reacted and self-combined, the density and bonding strength of the resin grinding wheel are increased, and the resin grinding wheel shows good comprehensive performance. , but also has the advantage of being easy to control.

Description

technical field [0001] The invention relates to the technical field of resin grinding wheel production, more specifically, it relates to a resin grinding wheel and a preparation method thereof. Background technique [0002] Grinding wheel is the main tool for grinding. It is a porous substance composed of abrasives, fillers and binders. It is widely used in metallurgy, construction, railway and other fields. It is mainly used for cutting and polished. At present, in grinding metal with grinding wheels, generally the higher the grinding ratio, the greater the grinding vibration amplitude, the rougher the workpiece grinding surface and poor flatness, and the lower the grinding ratio, the smaller the grinding vibration amplitude, and the smoother the workpiece grinding surface. With the continuous advancement of science and technology, the requirement for the smoothness of the polished surface of the workpiece is increased, and there is an urgent need for a method to improve t...
