一般来说,摇臂钻的摇臂回转角度为±180°,其加工范围较广。而主轴下端在至底座工作台面最大距离则视其机床型号而定。如Z3040×16H_(max)=1250mm;H_(min)=340mm;对一般中小工厂如要钻1500～3000mm轴线方向孔时,就较为困难。为此,我们在摇臂钻的左边挖了一个500×500×1600mm的孔(具体根据加工范围而定),用砖 In general, rocker arm rocker swing angle of ± 180 °, its processing a wide range. While the bottom of the spindle in the base table to the maximum distance depending on the machine model may be. Such as Z3040 × 16H_ (max) = 1250mm; H_ (min) = 340mm; on the general small and medium factories such as drilling 1500 ~ 3000mm axial direction hole, it is more difficult. To this end, we dug a 500 × 500 × 1600mm hole to the left of the rocker arm (depending on the processing area)
