本机由三孔钻和仿形铣两大部分组成，垂直方向在操作杆作用下,仿形触头杆沿仿形板孔移动,带动铣刀按1:1的比例进行仿形铣削;水平方向电机通过齿轮箱带动三个转动钻头,在钻孔进给手柄作用下实现三个孔的同时钻削。仿形铣仿形范围：290×90×100mm,三孔钻中心距：21.5×21.5mm。
This machine is made up of three-hole drilling machine and copy routing machine. Controlled by the operation pole, in the vertical direction, the copy routing feel pole moves along the copy routing plate, which drive the milling cutter to work with the scale:1:1,in the horizontal direction, through gear case and controlled by the feeding handle the electric motor drive the three special-purpsed aiguilles to drill at the same time. Copying range(L×W×H) 290×90×100mm，Drill center distance 21.5×21.5mm.
