The invention discloses a ceramic silicon carbide grinding wheel containing carbon reinforced fiber. The ceramic silicon carbide grinding wheel is prepared from following raw materials, by weight, 55 to 65 parts of silicon carbide, 30 to 35 parts of diamond abrasive, 10 to 13 parts of a short carbon fiber pre-dispersed material, 2 to 3 parts of a sintering additive, 4 to 5 parts of lanthanum hydroxide, 1 to 3 parts of potassium carbonate, 4 to 5 parts of kaolin powder, 2 to 3 parts of stearamide, 2 to 3 parts of epoxy resin, 1 to 2 parts of polyvinyl alcohol, and 80 to 90 parts of deionized water. The added short carbon fiber is capable of improving mechanical properties of silicon carbide, increasing breaking tenacity of ceramic, increasing strength and compactness of ceramic biscuit, and satisfying mechanical processing requirements; the added kaolin powder and epoxy resin are taken as binding agents, holding strength with the abrasive is increased, firm bonding is realized, hardness and grinding performance of the ceramic silicon carbide grinding wheel are improved, and service life is prolonged.
