微小喷嘴旋流槽棱边处的毛刺用传统研磨方法难以去除，本文提出了利用旋转电磁场带动微细磁针旋转与喷嘴形成碰撞来实现对喷嘴旋流槽棱边处的抛光处理这一新的研磨方法，解析了旋转磁场的产生原理及电磁研磨机的工作原理；分析了电磁研磨机对微小喷嘴棱边处毛刺的去除机理；进行了抛光试验，用3D超景深电子显微镜观察喷嘴棱边处并记录研磨前后的照片。试验结果表明，电磁研磨机可以对微小喷嘴旋流槽棱边处的毛刺起到良好的去除作用。

It is dififcult to remove the burr on the edge of swiler of micro nozzle by using traditional polishing methods. A new polishing method is developed which takes advantage of revolving electromagnetic ifeld to let the tiny magnetic needles revolving, and colliding with nozzle, so as to polish the edge of swiler of micro nozzle. Firstly, the generation mechanism of the rotating magnetic field and the working principle of the electro-magnetic mill are introduced, and then the removal mecha-nism of the burr on the edge of micro nozzle by using electro-magnetic mill is analyzed, at last, the polishing ex-periment is also conducted. The 3D depth of ifeld electron microscopy is used to observe the picture of burr on the edge before and after polishing. Finally, experiment shows that using electro-magnetic mill can have a good effect on removing burr on the edge of the micro nozzles.
