【摘要】：采用气固两相流双喷嘴雾化水冷法制备出球形、近球形的磁性磨料,并用场发射扫描电子显微镜(FESEM)和能谱仪(EDS)分别进行磁性磨料表面形貌的观察和表面元素的定量定性分析,在XK7136C型数控铣床平面磁力研磨装置上进行研磨性能分析。结果表明:气固两相流双喷嘴雾化水冷法制备的球形磁性磨料具有良好的研磨光整效果,磁性磨料在使用40 min后仍然具有良好的精密光整加工能力。
[Abstract]:Spherical and near spherical magnetic abrasives were prepared by gas-solid two-phase flow double nozzle atomization water cooling method. The surface morphology of magnetic abrasive and the quantitative and qualitative analysis of surface elements were carried out by field emission scanning electron microscope (FESEM) and energy dispersive spectrometer (EDS), respectively. The grinding performance was analyzed on the plane magnetic grinding device of XK7136C NC milling machine. The results show that the spherical magnetic abrasive prepared by gas-solid two-phase flow double nozzle atomization water cooling method has good grinding and finishing effect, and the magnetic abrasive still has good precision finishing ability after using 40 min.
