摘　　要：　针对ELID超精密磨削的特点,对ELID磨削热产生的机理进行了分析,建立了ELID磨削热源模型和热量在工件、砂轮、电解液及磨屑间分配的模型,并进行了数值计算.计算结果表明:ELID磨削热量主要由磨粒与工件的耕犁和摩擦作用产生,磨削热量在各部分的分配是随磨削区内位置改变的分布函数,电解液和砂轮带走绝大部分的磨削热量.According to the feature of the ELID grinding, mechanism of the ELID grinding heat is analyzed. The heat source and heat partition models of ELID grinding among work piece, grinding wheel and electrolyte are established. The numerical calculation is carried on. Calculating indicates: ELID grinding heat is mainly produced by function between grit and work piece; partition of grinding heat among work piece, grinding wheel and electrolytic liquid are distribution function changed in position; electrolytic liquid and grinding wheel take away most heat of grinding.
