大型定型辊简体是上海涤纶二厂短丝后处理生产线中的一个比较关键的零部件。该件直径1000mm、长1250mm,内腔几何造型比较复杂,外表面镀硬铬,尺寸公差和形位公差要求比较高,同轴度为声0.03,圆度为0.05,圆柱度为0.05,跳动为0.05,表面粗糙度为R_a0.8μm。 为了解决此大件磨削加工问题,利用一台C630车床上增设了一个专用支座用于安装工件,通过C630车床完成车、磨、抛光等工序,成功地解决了这个加工难题。
Large-scale stereotypes roller Shanghai Dacron Factory is short staple after-treatment production line in a more critical part. The diameter of the piece 1000mm, length 1250mm, lumen geometrical shape is more complex, the outer surface of hard chrome plated, dimensional tolerances and geometric tolerance requirements are relatively high, the coaxiality of sound 0.03, roundness of 0.05, cylindricity of 0.05, beating 0.05, surface roughness R_a0.8μm. In order to solve this large-size grinding problem, a C630 lathe is equipped with a special support for installing workpieces, and the C630 lathe is used to complete the process of car, grinding and polishing, thus successfully solving this processing problem.
