目前,各段货车滑动轴承球墨铸铁轴瓦的抛光作业,都是采用大布轮(直径在300mm以上)顺向抛光。这种抛光方式,由于被抛面是弧面,抛光加压时必然损坏布砂轮粘砂面,造成金刚砂大量损失。并且由于布轮本身也是圆弧面,抛光时与轴瓦接触面很小,所以效率也就很低。再加上轴瓦内弧面刀花与布轮旋转方向垂直,要达到抛光要求的粗糙度,还必须将刀花磨平,因此,这种抛光 At present, the various sections of the sliding bearing bearing ductile iron castings are polish operations, are using large cloth round (diameter 300mm above) forward polishing. This kind of polishing method, because the surface is paved arc, polishing pressure will inevitably damage cloth sand sticky sand surface, resulting in a large loss of carborundum. And because the cloth wheel itself is also a circular arc, polish the contact surface with the bearing is very small, so the efficiency is very low. Coupled with the bush within the arc flower knives and cloth wheel rotation direction perpendicular to the roughness required to achieve the desired polishing, but also the knife must be polished, therefore, this kind of polishing
