在车床上自动走刀钻孔替代尾座常规钻孔，只需制造一简单工具（见图１），现介绍如下。做一个莫氏锥度套Ｄ×Ｌ，侧面焊钢条块１３×２５×１００ｍｍ，将此工具体夹在车床刀架上，把锥柄钻头套入工具体中，即可利用机床自动走刀钻孔。有时，钻中心孔和　１５ｍｍ以下的孔钻头 Instead of the conventional tailstock drilling, an automatic tooling hole drills a lathe simply by making a simple tool (see Figure 1), which is described below. Do a Morse taper sets D × L, the side of the welded steel bar 13 × 25 × 100mm, the tool body clip on the lathe turret, the taper shank bit into the tool body, you can use the machine tool to automatically go hole. Sometimes drill the center hole and hole drills below 15mm
