单纯性磁性研磨粒子特性的研究

Research on Characteristics of Simply Magnetic Abrasives Grains

利用磁力线能够穿透非磁性材料的特性,用磁性研磨法对小型的非磁性工件进行精密抛光。通常做研磨粒子的方法造价高,且种类不齐全。因此采用简单方法把铁粒子、氧化铝研磨粒子和研磨液混合,直接参与到磁性研磨中,实验证明该方法可取得很好的抛光效果。

Utilize the eharaeteristie that magnetie foree line may penetrate the nonmagnetie material, use the magnetie abrasive finishing （MAF） method eomplete to the nonmagnetie small workpieee surfaee preeise proeessing. In order to enhance polishing efficieney, usually with the magnetic particles and abrasive particles mixes together in the sinter method or the eementation method, the eost is higher, the variety is not also complete. Therefore, use the simply mixed method mixed the ferromagnetism iron partieles, the alumina partieles and the lipin, directly participates in magnetism polishing, already obtained the good proeessing effect through the experiment.
