摘要：
It is shown that fragmented particles are preferable to spherical particles for magnetic-abrasive finishing. The cutting elements of such powders are microscopic projections that determine the roughness of the finished surfaces. For a given volume of magnetic-abrasive powder, a decrease in the diameter of the particles increases the number of cutting centers. To maximize metal removal over the duration of the polishing operation and shorten the amount of time needed to reach the minimum value of Ra, it is necessary to use progressively finer abrasive powders as Ra decreases during polishing.
