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。
