我厂转向节零件锥孔上的键槽,在插床上加工。插刀头用白钢刀手工磨制,见图1。由于键槽尺寸精度高,且与孔角度公差严,要求对称,加工较困难,经常出现键槽角度超差,质量一直不稳定。插刀头装入刀杆的方孔中使用。为便于插槽时对刀,除对刀杆方孔有对称要求外,插刀头与 I plant steering knuckle parts taper keyway, in the slotting machine processing. Insert the knife with a white steel knife manual grinding, see Figure 1. Due to the high precision keyway size, and tight tolerances with the hole angle, requiring symmetry, processing more difficult, often appear keyway angle tolerance, the quality has been unstable. Insert the cutter head into the square hole used in the cutter. In order to facilitate the slot when the knife, in addition to the square hole on the arbor have symmetrical requirements, insert the first knife and
