【摘要】 本论文以磁性研磨加工原理为切入点，以精密磨削理论和摩擦学理论为依据，分析研究了磁性研磨加工中磁性磨料磨粒的磨削机理，提出了磁性研磨加工中对磁性磨料加工性能的要求。就磁性磨料的组成成分、结构形状、规格大小以及研磨压力的形成进行了分析研究，并研制开发出粘结法、烧结法、热压烧结法等三种系列的磁性磨料。 在此基础上，利用磁性研磨装置，就已开发的三种磁性磨料，针对多种材质的被加工工件进行了磁性研磨的工艺实验。重点对磁性磨料的加工特性进行了实验研究，分析了磁性磨料中不同的组成成分和各组成成分间的不同配比、磁性磨料磨粒的粒度大小、磁性磨料的最佳研磨时间、磁性磨料中不同的添加剂等对磁性磨料的耐用度及对磁性磨料加工特性的影响状况，从而获得了影响各种系列磁性磨料加工效果的实验数据和曲线，进而确立了各种磁性磨料的性能参数。 此外，本课题还核算了磁性磨料的生产成本，并对其经济性进行了分析、对比。最后，提出了磁性磨料今后的研究方向。期望本课题的开发研究和实验分析结果能为更好地开发研制磁性磨料奠定一些基础，如果能为磁性研磨加工新技术的更快发展和推广应用做出一些微薄成绩将十分欣慰。更多还原

【Abstract】 According to the machining principle of magnetic abrasive finishing(MAF) and the theory of precision grinding and tribology/the grinding mechanism have been analyzed. Then, the requirement on the machining performances of magnetic abrasive grains (MAGs) have been put forward. In the paper, following items concerned with MAGs have been studied: composition, structure, shape, size and formation of finishing pressure in grinding process. A series of MAGs including resin binding one, sintering one and one sintered with high-pressure have been developed.Using the magnetic abrasive device, the experiments of MAF with above mentioned MAGs, which aimed at the different materials work-pieces, have been made. The factors effected on the characteristic of MAGs, such as different mixture ratio of ingredients, abrasive materials, grain size, the optimum finishing time, kinds of addtives and its content, endurance and so on, have been analyzed. Consequently, the related datum and curveshave been obtained and the parameters on grinding performances have been determined afterwards.Moreover, economicity and the producing cost of MAGs have been accounted and compared. In the later of the paper, the problems concerned on MAGs to be solved have been raised. It is hope that the results of experiments will lay a foundation for further research of MAGs, rapid development and wide application of the MAGs technology.更多还原
