我厂过去加工細紗机零件“皮輥壳”上的Φ5/8″～5/16″、長5″～15″的孔时,是先用接長了的鑽头鑽孔,再用三角鑽扩孔,最后用里眼样板刀鏜孔,并且最少要光兩次,塞規才能通过,所以效率低。同时样板刀磨損了就得换新的,很浪費。现在改进了一种可調整的浮动鏜孔刀,用来代替样板 In the past, when processing Φ5 / 8 “~ 5/16” and 5 “~ 15” holes on the roller shell of the spinning frame, we drilled first the drill bit with a longer length, Reaming, and finally with the eye-model knife boring, and at least twice as light, plugs to pass, so inefficient. At the same time model knife wear have to change, it is wasteful. An adjustable floating boring cutter is now being used to replace the template
