一、问题的提出和一个基本假设砂轮成型时,常出现两端面不平行的现象(图1),后经加工而成为标准圆柱体。砂轮未加工时,尽管两端面不平行,由于投料分布基本是均匀的,所以并不引起重心偏移。但加工磨平后,反因各部分磨去质量的不一而引起重心偏移。本文试对此情况下产生的静不平衡作 First, the question raised and a basic assumption Grinding wheel, often appear two ends of the phenomenon is not parallel (Figure 1), after processing and become a standard cylinder. When the grinding wheel is not machined, although the two end faces are not parallel, the center of gravity does not shift due to the basically uniform material distribution. However, after the processing of polished, due to the various parts of the quality of the mill to cause uneven center of gravity shift. This article tries to make the static imbalance in this case
