摘　　要：分析G95Cr18钢的加工特性和产生套圈沟道磨削烧伤的原因。以2个型号轴承内、外圈沟道磨削为例,从砂轮选择、磨削留量分配、砂轮与工件转速、进给速度、进给量、光磨时间等方面进行试验和分析,通过优化工艺参数、细化工艺过程,有效避免了沟道磨削烧伤的发生。另外,对砂轮修整频率和切削液对套圈磨削质量的影响也进行了分析。The machining characteristics of G95Cr18 material and the causes of groove grinding burns are analyzed. Two different types of bearings are selected for the inner and outer ring groove grinding process.The grinding process is tested,from grinding wheel selection,grinding allowance distribution,rotating speed of grinding wheel and workpiece, speed of feed,the feed rate and the time of grinding and so on.By optimizing the process parameters and refining the process,the occurrence of burn of grove grinding is effectively avoided.In addition,the grinding wheel dressing frequen-cy and the impact of cutting fluid on ring grinding quality were also analyzed.
