LK557系列雙油缸上拉式內拉床用途及特點：

本系列機床為雙油缸雙導柱上拉式立式內拉床，可廣泛應用于各種形狀內孔表面的拉削加工（如長通孔、內花鍵、 內齒圈以及各種成型通槽），生產效率高，適用于大批量生產。
    ●拉削中心與油缸、導柱處于同一垂直面，工作臺無傾覆力矩，工作平穩，拉削精度高。

●液壓系統采用伺服控制，節能降噪，且液壓油升溫小，工作平穩，能無極調速。

●具有超負荷保險裝置，并采用人機界面讀寫操作方式。

●具有自動循環功能、分段循環及點動調整功能，有PLC程序控制，所有操作在總按鈕站上完成，方面可靠

●占地面積小，地面式安裝，無需地坑或站架，與自動線實現無縫對接。

●具有自動沖屑、自動調刀、自動推料等功能。

●適宜加工對工件徑向和端面跳動精度要求高的工件。

Applications and Advantages:

This type of vertical internal machine is designed with twin cylinder, double-column and lifting worktable. It can be widely used to broach the inner surface of holes with various shapes, such as long through-hole, internal splines, inner gears and other through grooves. It is applicable for mass production due to its high production efficiency.

● stable performance and high broaching precision thanks to the less of overturning moment in worktable as lead screw and column lie in a lie of action with the broaching station.

● servo controlled hydraulic system provides lower power-consumption, lower noise, lower oil temperature, stable performance and stepless speed regulation.

● equipped with a safety device against overload and human-computer interface.

● Work modes: automatic cycle, segmented cycle and inching adjustment. PLC programmed control allows all operations to be completed on main button control station conveniently and reliably.

● low space requirement, ground-level installation of the machine without a pit or pedestal, simple integration into automatic production lines.

● with functions of automatic chip flushing, automatic tool adjusting and automatic workpiece pushing.

● less residue chips on broaching tool thanks to the function of rotary chip brushing.

● designed to machine workpieces which has high demand on its radial and end face run-out.
