a new type of magnetic abrasive is introduced and its machining property has been studied through experiments from which the optimal proportion of the abrasive mixture has been obtained.
介绍了一种新型的磁性磨料,并对该磨料的加工性能进行了实验研究,得到了该磨料的最佳配比。
the composition is well-proportioned, density is equal, and machining property is good. so it is can be made into several kinds of streaky board. thereby it becomes the best board to carve.
