The invention discloses an abrasion-resistant S-shaped grinding wheel and a hot-press forming technology thereof. The abrasion-resistant S-shaped grinding wheel comprises the following main materials in volume fraction: 12 to 15% of diamond, 20 to 25% of copper, 40 to 45% of iron, 3 to 8% of tin, 5 to 8% of nickel, 5 to 8% of cobalt and 3 to 5% of auxiliary material alloy powder. The continuous tooth S-shaped grinding wheel is produced through the steps of batching, premixing, total mixing, cold pressing performing, hot pressing sintering, primary cooling, high frequency welding, secondary cooling, surface treatment, paint spraying, edging, and the like. According to the S-shaped grinding wheel produced through the formula and the technology, the strength is improved, the abrasion resistance is improved as well, the service life is prolonged in the actual use process, the production cost is greatly reduced, the resources are saved, and the technology is environment-friendly, sanitary and safe in the production process.
