在锥度弧形盲孔的加工过程中，由于盲孔较深且根部形状复杂且尺寸较小，传统的车床和深孔钻镗床均不具备加工条件，加工不出来孔的形状和尺寸。通常的做法是在深孔钻镗床上利用成型扁钻加工。由于成型扁钻制造周期长，费用高，加工过程容易打刀，对操作者技能水平要求高，且加工质量不易保证。鉴于此，我公司设计了一种用于加工锥度弧形盲孔的镗刀杆装置。 During the processing of tapered arc-shaped blind holes, because the blind holes are deep and the root shape is complex and small in size, traditional lathes and deep hole drilling and boring machines do not have the processing conditions, and the shape and size of the hole cannot be processed. The usual practice is to use a forming flat drill on a deep hole drilling and boring machine. Due to the long manufacturing cycle and high cost of forming flat drills, the processing process is easy to cut, the operator's skill level is high, and the processing quality is not easy to guarantee. In view of this, our company has designed a boring bar device for machining tapered arc-shaped blind holes.
