在许多影响微孔钻削的因素中,切削刀具是关键因素,而不考虑刀具的重要性则为小孔钻削中经常忽视的问题之一。在许多应用中应考虑下列问题:多大的进给量能较快钻进而不致损坏钻头?钻削可达到的孔的位置公差和尺寸公差是多少?所希钻头耐用度是多少?换用别种钻头能否缩短工时,提高经济 Among many factors that affect micropore drilling, cutting tools are a key factor, regardless of the importance of the tool, which is one of the most frequently overlooked problems in hole drilling. The following questions should be considered in many applications: How much feed can be drilled faster without damaging the drill? What are the tolerances and dimensional tolerances for the holes that can be drilled? What is the durability of the drill? Drill bit can shorten the working hours, improve the economy
