When processing precision parts of deep-hole workpieces, since the tool handle is limited by the diameter and depth of the hole, it is required that the tool handle should be slender, but the slender tool handle will cause its rigidity to be poor, and it is easy to generate vibration and tool loss during turning . In addition, due to the depth of the hole, the drill bit is easily deflected during the drilling process, causing the axis of the hole to be skewed.
