在一个没有特种机器设备的工厂中,如果要镗制不太多的椭圆或不规则的孔,像锅炉水箱小手孔之类,是有点麻烦的。我介绍一个镗制的方法,请大家指正。但这工具最好是装住大铣床的刀杆位置上,工作物则装在铣床的工作台上,走刀是靠工作台的上下动作。如万一连大一点的铣床都没有,那只好装在车床头上,但工作起来却不及铣床上方便 In a factory without special machinery and equipment, if you want to bored not too many oval or irregular holes, such as small hand-held boiler tank hole is a little cumbersome. I introduce a boring method, please correct me. However, this tool is best installed on a large milling cutter arbor position, workpieces are installed in the milling table, walk through the table up and down action. If even the larger milling machines are not, it had to be installed in the lathe head, but not as easy to work on the milling machine
