-用于鋁合金門窗各類鎖安裝孔槽的銑削加工。
-由水平方向的三孔鉆與垂直方向的仿型銑組成。
-三孔鉆機(jī)頭上下運(yùn)動增加了導(dǎo)柱導(dǎo)向，保證三個(gè)孔對底面的平行。
-三孔鉆后置布置，操作方便，符合人體工學(xué)原理。
-三孔鉆氣液阻尼自動進(jìn)給，減輕了工人的勞動強(qiáng)度。
-仿形采用仿形模板和輔助定位兩種仿形方式。

-Milling all kinds of lock holes.
-Formed by three-hole drill part (horizontal direction) and copy milling part (vertical direction).
-Movement of three drill head increases the guide pin under the guidance, guarantee the three holes on the under-side of the parallel.
-Three drill  rear  layout, easy operation, accord with human body engineering principle.
-Automatic  feeding of  three drill gas-liquid damping, reduce the labor intensity of the workers.
