在普通车床上进行批量加工时,为了控制中心钻的钻孔深度,提高生产效率,可根据中心钻的尺寸规格制作如简图所示的专用刀杆。当使用较小的带护锥的中心钻时,这种刀杆特别有用。刀杆的夹持部分应与装在车床尾架上的轧头相配,通过调节装在中心钻尾端的一对锁紧螺钉来确定中心钻的轴向位置,而在中心钻旁边的定位销则作为钻孔深度的标记。将定位销的伸出端磨圆并抛光,这样在钻削中心孔时,即使是十分敏感的材料(如黄铜、塑料等),只要采用软棒料加工的
In the ordinary lathe for batch processing, in order to control the center of the drilling depth of drilling, improve production efficiency, according to the center of the diamond size specifications produced as shown in the figure dedicated arbor. This type of arbor is particularly useful when using a smaller center cone with cone guard. The clamping part of the shank should be matched with the rolling head mounted on the tailstock of the lathe. The axial position of the center drill is determined by adjusting a pair of locking screws installed at the tail end of the center drill. The positioning pin As a mark of the drilling depth. Rounding and polishing the projecting end of the dowel pin, so that even a very sensitive material (such as brass, plastic, etc.)
