摘　　要：采用粘结法制备磁性磨料,对磁性磨料制备工艺进行了优化,确定了最终的工艺方案。研究了在磁性磨料粒度及配比不变的情况下,结合剂的种类、结合剂中粘结剂与固化剂的质量比以及混料与结合剂的质量比对轴承钢外圆表面粗糙度的影响。试验结果表明,使用粘结剂为环氧树脂B制备的磁性磨料具有较好的研磨效果,并且当粘结剂与固化剂的质量比为3∶1,以及混料与结合剂的质量比为6∶1时,研磨效果最佳。磁性磨料光整加工技术为轴承钢的表面加工提供了一种新方法。The bounded Magnetic Abrasive Particles （ MAP） are prepared and the abrasive preparation process are optimized and determined the final process .Studied under the condition of invariable in magnetic abrasive particle size and proportion ,the effect of the kinds of binder ,the quality of adhesive and curing agent ratio in the binder and the quality of the magnetic abrasive and binder ratio on the roughness of bearing steel cylindrical surface .The results show that the performance of MAP which use epoxy resin adhesive B is better ,and when the quality of adhesive and curing agent ratio is 2∶1,and the quality of the magnetic abrasive and binder ratio is 6∶1,the grinding effect is best .This magnetic abrasive finishing machining technology provides a new way for the surface of the bearing steel processing .
