在车床作业中,常常会遇到这样的工件:要加工一个盲孔,且孔深还有一定的要求。根据作者的经验,采用这种搪杆(图1)会获得满意的效果。搪杆可作成两种:一种长度为6in,另一种为12in;刻度板宽度前者为1/4in,后者为1/2in。刻度精度如能达到1/100in当然最好。最前端的1in,在安装刀头时应仔细调整,保证精度。使用这种搪杆加工,比起车床用止动挡铁要直观、简便和可靠。
In the lathe operation, often encounter such a workpiece: To process a blind hole, and deep hole there are certain requirements. According to the author’s experience, the use of such embossing rod (Figure 1) will be satisfactory results. There are two types of corkscrew: one 6in in length and the other 12in; the former has a width of 1 / 4in and the latter 1 / 2in. Graduation accuracy of 1 / 100in, of course, the best. The front 1in, the installation of the blade should be carefully adjusted to ensure accuracy. The use of this type of capping process is more intuitive, easier and more reliable than latching stoppers for lathes.
