摘 要
T611鏜床是一種主要用鏜刀在工件上加工孔的機(jī)床。通常用于加工尺寸較大、精度要求較高的孔，特別是分布在不同表面上、孔距和位置精度要求較高的孔，如各種箱體、汽車發(fā)動(dòng)機(jī)缸體等零件上的孔。臥式鏜床的主軸水平布置并可軸向進(jìn)給，主軸箱沿前立柱導(dǎo)軌垂向運(yùn)動(dòng)，工作臺可縱向或橫向運(yùn)動(dòng)，可鉆、擴(kuò)、鉸、和鏜孔及車削內(nèi)、外螺紋、攻螺紋、車外圓柱面、端面及用端面銑刀、圓柱銑刀銑平面等。

Abstract
The boring is one kind mainly processes the hole with the boring cutter on the work piece the machine tool. Usually uses in the finishing size being big, the precision request high hole, specially distributes on different superficial, the pitch of holes and the position precision request high hole, like each kind of box body, components and so in motor car engine cylinder body holes. The horizontal boring machine main axle level arrangement and may the axial feed, the headstock along the front column guide rail vertical movement, the work table be possible longitudinal or the transversal motion, may drill, expand, the articulation, and bores and in the turning, the external screw thread, the tapping, the vehicle outer annulus cylinder, the end surface and uses the face cutter, the column milling cutter mill plane and so on.
