提出了一种与实心孔钻头相类似的扩扩孔,其头部装有两个径向可调的凸三边形刀片;用于金属材料上扩孔,能达到配合精度,是可供选择的一种终加工方法。这种刀具将可转位和可调式刀具的优点融为一体。
A kind of expansion hole similar to a solid hole bit is proposed, and two radially adjustable convex triangular blades are arranged on the head. It is an alternative for expanding the hole on the metal material to achieve the matching precision A final processing method. This tool combines the advantages of indexable and adjustable tools.
