在车床上加工的零件,有的外形比较复杂,不能依靠外表面或内表面进行找正;有的不能直接在卡盘上进行安装,如加工车床小刀架的上、下滑板、箱体、支架等;有的零件很长,用卡盘顶针装卡刚度不够,无法加工,如车床上的光杠,丝杠、主轴的加工等;象这些类型的工件都属于中等复杂零件的加工。必须采取特种装卡方法,例如用中心架,跟刀架、花盘,角铁、轴胎等方法进行安装。对于特种材质的加工,由于切削性能不良,也需要采取不同的措施进行车削。
Some parts machined in the lathe, some of the more complex shape, can not rely on the outer surface or inner surface to be found; some can not be directly installed on the chuck, such as processing lathe knife turret upper and lower skateboards, boxes, brackets Etc .; some parts are very long, with the chuck thimble mounted card rigidity is not enough, can not be processed, such as lathe light bar, screw, spindle processing; like these types of parts are medium complex parts processing. Special installation methods must be taken, for example, the center frame, the knife holder, the face plate, the angle iron, the axle tire and the like. For special materials processing, due to poor cutting performance, but also need to take different measures for turning.
