| 摘 要： | 磁性磨料磁力研磨是近年发展起来的一种高效率、高质量的抛光方法，能够加工复杂外形工件和各种内壁、内腔表面，具有加工装置易于控制、工作环境清洁、加工成本低等优点，具有广阔的应用前景。本文设计、制造了加工装置并进行了一系列的试验，在研磨过程各主要参数对研磨的影响作了研究。试验结果表明，研磨初期加工效率较高，但随着研磨时间的延长，研磨效率降低，研磨质量提高不多；工件转速越高，研磨效率越高，而对研磨质量则没有影响；研磨存在最佳的加工间隙与电流强度值，在此条件下，研磨效率高，研磨质量也较好。本文最后对加工机理作了理论分析，认为磁极的设计与制造研磨能力好、磁性强的磁性磨料是非常重要的。

| Abstract: | This paper deals with the machining process using magnetic abrasives. Using an apparatus designed and made, a series of experiments are carried out, where the workpiece is cylindrical and the magnetic abrasives used are mainly Fe and Al 2O 3, for investigating the effects of machining time, working gap, rotating speed of workpieces, magnetic flux density on machining efficiency and surface roughness. At the end of this paper, the machining mechanism is also discussed. |
