Study on Processing Parameters and Surface Morphology of Quenched and Tempered 45 Steel in Magnetic Abrasive Finishing

  • 摘要: 开展磁力研磨加工方法对调质45钢的加工能力以及最优工艺参数的研究。实验采用SiC磨料和铸钢粉的混合物作为磁性磨料,钕铁硼永磁铁做磁极,利用正交试验方法从研磨液类型、磨料粒度、磨料比重、加工间隙和磁场强度5个因素分别4个水平进行实验设计,通过比较加工前后工件被加工区域表面粗糙度改善率(%ΔRa)进行磁力研磨工艺参数的优化。实验结果表明,磁力研磨加工调质45钢的优化后工艺参数为:油酸研磨液、360#SiC磨料、磨料比重30%、加工间隙1 mm、0.359~0.133T(Ø30 mm×20 mm永磁铁);经磁力研磨光整加工后,工件表面粗糙度由初始的1.941 μm降至1.053 μm;磁力研磨加工后工件表面的加工纹理得到有效降低。
