普通车床加工大型复杂内型面是比较困难的工作,因为加工大型复杂内型面时,加工者的视线被工件的实体挡住,不能直接看到车刀在切削时的移动轨迹,因此以往加工常常达不到设计要求。我厂没有大型数控车床,为了解决这个问题,我们在C 61100车床上,稍加改装,革新成功了“光电跟踪复杂型面加工装置”(图1)。在加工风筒管 Ordinary lathe machining large complex inner surface is a more difficult job, because the processing of large complex inner surface, the operator’s line of sight is blocked by the solid body of the workpiece, can not directly see the turning tool in cutting the path of movement, so the past often Not meet the design requirements. I do not have a large CNC lathe machine factory, in order to solve this problem, we C 6100 lathe, a little refit, successful reform of the “photoelectric tracking complex surface processing device” (Figure 1).
