LK557系列双油缸上拉式内拉床用途及特点:
本系列机床为双油缸双导柱上拉式立式内拉床,可广泛应用于各种形状内孔表面的拉削加工(如长通孔、内花键、 内齿圈以及各种成型通槽),生产效率高,适用于大批量生产。
●拉削中心与油缸、导柱处于同一垂直面,工作台无倾覆力矩,工作平稳,拉削精度高。
●液压系统采用伺服控制,节能降噪,且液压油升温小,工作平稳,能无极调速。
●具有超负荷保险装置,并采用人机界面读写操作方式。
●具有自动循环功能、分段循环及点动调整功能,有PLC程序控制,所有操作在总按钮站上完成,方面可靠
●占地面积小,地面式安装,无需地坑或站架,与自动线实现无缝对接。
●具有自动冲屑、自动调刀、自动推料等功能。
●适宜加工对工件径向和端面跳动精度要求高的工件。
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.
