So high precision of the mechanical cutting of each segment end face was required. For example,it was specified that planeness≤0.25mm,roughness≤12.5μm,inclination error between the axes and end face≤20"(1/10000).
钢塔节段端面机械切削加工及精度管理南京长江三桥每个钢塔柱共有22个节段,节段间采用“端面金属接触+摩擦型高强度螺栓”连接传力,这就要求每个节段有很高的端面机械切削加工精度,如:端面平面度≤0.25mm,粗糙度≤12.5μm,节段轴线与端面直角度≤20″(1/10000)。
