提起“滚压加工”大家都很熟悉。它是在常温下,用很硬的滚轮、滚珠或滚柱,在一定压力作用下,沿零件表面滚动而把工件表面压平,提高零件表面光洁度的加工方法。滚压所以能够压平粗糙表面,提高表面光洁度,是由金属塑性变形性质决定的。即在一定压力下,金属发生了永久变形。当滚压力作用于零件表面时,材料产生了向两个方向的流动(图1a)。这样便把原来波峰处的金属挤向波谷而填平,同时形成新的小凸起。图1b由上到下,表示了滚压前后工件表面的变化情 Lift “rolling processing ” everyone is familiar. It is at room temperature, with a hard wheel, ball or roller, under certain pressure, rolling along the part surface and the workpiece surface flattening, improve surface finish parts processing. Rolling so it can smooth the rough surface, improve the surface finish, is determined by the metal plastic deformation properties. That under certain pressure, the metal has undergone permanent deformation. When the rolling force acts on the part surface, the material creates a flow in both directions (Figure 1a). In this way, the metal at the original crest is pushed into the trough and filled up, and at the same time a new small bulge is formed. Figure 1b, from top to bottom, shows the change of the surface of the workpiece before and after rolling
