轴的挡圈槽(见图1),若不能在车床上加工,也可利用割槽工具(见图2)在钻床上加工。现将操作方法简介如下。将本工具夹持在钻床上,使之随钻床主轴回转。加工时将刀体的尾端插人工件孔中,如同正常钻孔一样进刀。由于刀体尾端台阶A接触工件平面后轴向进给停止,继续用力后刀杆克服弹簧张力沿刀体导向杆向下移动,迫使刀头座沿刀杆的60°槽张开,刀头座
Shaft retaining ring groove (see Figure 1), if it can not be machined in the lathe, you can also use the grooving tool (see Figure 2) on the drilling machine. Now the operation method is as follows. Clamp the tool on the drilling machine and make it rotate with the drilling spindle. When processing the end of the body into the workpiece hole, as the same as the normal drilling into the knife. As the rear end of the cutter body A contact with the workpiece plane after the axial feed to stop, continue to force the knife overcome the spring tension along the knife body guide rod down to force the cutter head seat along the arbor 60 ° slot open, the cutter head seat
