MAGIC抛光方法及其研究进展

Introduction to MAGIC Polishing and Review on its Research

MAGIC(MAGnetic Intelligent Compounds)是由包含磁性颗粒和磨粒的磁性流体固化形成的新型抛光材料。MAGIC中磁性颗粒形成的特殊排列可使磨粒均匀分布,因而MAGIC抛光可高效地获得小粗糙度的表面;另外,MAGIC可浇铸成形,故可用于复杂型面及狭小内表面的机械化抛光。简要介绍了MAGIC磨石的组成、制作方法、抛光效果以及目前的研究进展情况。

MAGIC（ MAG-netic Intelligent Compound）, a new type polishing pad, is one kind of solidified magnetic ferrofluid containing both magnetic particles and abrasive particles. The special sturctures formed by magnetic particles under the applying magnetic field can induce uniform distribution of abrasive particles in MAGIC, therefore, the small surface roughness can be obtained efficiently by polishing with MAGIC pad. Additionally, since it can follow the shape of workpiece, MAGIC is suitable for mechanical polising of complicate-shaped surfaces and narrow dies. The composition, manufacture method and the polishing results of MAGIC pad on some special worpieces were introduced. A review on the research activities of MAGIC and the faced problems were included.
