一般的大型蜗轮,都是在铣床上利用分度头扳角度的方法来铣切的;我厂在加工一种直径在800公厘以上的蜗轮时,由于工件太大,在铣床上加工很困难,所以改在镗床上来加工,效果很好。加工的方法如图1所示。将立铣床上的附件—转盘工作台,安置在 General large-scale worm wheels, milling machines are used in the angle of the sub-head milling method; I plant in the processing of a diameter of 800 mm worm wheel, the workpiece is too large, the milling machine is difficult , So change to boring machine processing, the effect is very good. Processing method shown in Figure 1. Place the attachment - turret table on the milling machine
