Ceramic grinding wheel for grinding metal diamond steel rail grinding wheel and preparation method of ceramic grinding wheel

The invention discloses a ceramic grinding wheel for grinding a metal diamond steel rail grinding wheel and a preparation method of the ceramic grinding wheel. The grinding wheel is prepared from, by weight, 10%-30% of low-temperature high-strength ceramic bond, 50%-200% of 25/30 diamond, 5%-30% of 320-mesh white corundum, 3%-15% of hollow balls, 5%-8% of dextrin powder and 5%-10% of tap water. Compared with the prior art, the grinding wheel has the advantages of being long in service life, high in grinding efficiency, few in generated grinding waste and low in comprehensive cost. Compared with a ceramic silicon carbide grinding wheel, the ceramic silicon carbide grinding wheel is mainly characterized in that a low-temperature high-strength ceramic bonding agent is adopted, the diamond serves as a grinding material, the hollow balls serve as a pore-forming material, and the grinding wheel is formed in a cold pressing, sintering and bonding forming mode. 本发明公开了一种修磨金属金刚石钢轨打磨砂轮的陶瓷砂轮及其制备方法，砂轮配方按重量百分比如下：低温高强度陶瓷结合剂
