Carborundum, emery abrasive carborundum powder is applied to two kinds of dry and wet production process of the most affordable of the abrasive, especially for the more rough treatment of the workpiece surface, while the treated surface, also requested a more elaborate occasions.

金刚砂，金刚砂磨料，金刚砂微粉是一种适用于干式和湿式两种生产工艺的最经济实惠的磨料，尤其适用于对较粗糙的工件表面进行处理，而处理后表面又要求较精细的场合。

The results showed that under the same polishing parameters, the particle size exerted an important influence on MRR and surface quality during unfixed-abrasive polishing, but played a less role during fixed-abrasive polishing. A fine surface roughness of R 1.5 nm was achieved by using diamond fixed-abrasive pad, and the function of self-conditioning was well realized.

结果表明：在相同的抛光工艺参数下，磨粒粒径在游离磨料抛光中对材料去除率和抛光后表面质量作用显著，而在固结磨料抛光中作用不显著；采用金刚石固结磨料抛光垫抛光能获得表面粗糙度约为R1.5 nm的良好表面质量，并在抛光过程中较好地实现了自修整功能。
