我厂生产的神牛-25拖拉机(原东方红-25)的半轴套管(如图1双点划线所示),生产量大,精度要求高。过去工件是以靠近两端法兰面的圆柱部位定位,夹压在有二个V形块的随行夹具上,用两台通用镗孔车端面组合机床配以固定夹具分别完成粗、精加工两道工序。工件的法兰端面和外圆柱面是依靠一把装在TT4241-F61镗孔车端面刀盘滑板上的宽刃镗刀,按先车法兰端面再车
I produced the Shenniu -25 tractor (formerly East Hong -25) of the half-shaft casing (double-dashed line shown in Figure 1), large production, high precision. In the past, the workpiece was positioned near the cylindrical part of the flange face at both ends and was clamped on a pallet with two V-shaped blocks. The two universal boring machine end face combined machine tools were used to complete the roughing and finishing two Road process. Workpiece flange face and the outer cylindrical surface is relying on a mounted on the TT4241-F61 boring machine cutters on the face of the wide-edge boring knife, according to the first vehicle flange face and then car
