在修理单位,有时会出现图1所示的零件、由于孔深且大,加工效率很低。为了提高生产效率,我制作了差值扩孔刀(图2)。在加工图1所示的零件时,差动扩孔刀较一般车刀提高工效五倍多。既节省大量的辅助时间,又减轻劳动张度,收到良好效果。 In the repair unit, sometimes shown in Figure 1 parts, because the hole deep and large, low processing efficiency. In order to improve production efficiency, I made a difference reamer (Figure 2). In the processing of parts shown in Figure 1, the differential reaming knife more than five times the efficiency of the general turning tool. It not only saves a lot of auxiliary time, but also reduces the tension of work and receives good results.
