摘　　要：为解决磨削曲轴轴颈端面时出现磨削烧伤的问题,在调整冷却系统无果的情况下,重新设计砂轮结构。通过调整砂轮端面和磨料类型,设计并制备新型电镀CBN砂轮,并以其进行磨削加工实验。结果表明:在冷却系统不变的情况下,新型电镀CBN砂轮可以解决此加工过程中的磨削烧伤问题。End face burn occurred when grinding CBN grinding wheel in grinding crankshaft journal and end face. In condition that adjusting the cooling system does not solve this problem, the structure of grinding wheel is redesigned by modifying the end surface and grain type. The newly designed and prepared electroplated CBN grinding wheel is tested on grinding experiment. Results show that at the same cooling system, the new electroplated CBN grinding wheel could solve the problem of burns in the mentioned process.
