L57系列上拉式拉床用途和特点
本系列机床为单油缸上拉式立式内拉床,用于拉削各种形状的内孔表面(如圆孔、内花键、内齿等),生产效率高,适用于大批量生产。
●采用液压传动,工作平稳,能无级调速。
●具有超负荷保险装置。
●具有自动循环功能、分段循环及点动调整功能。
●由PLC程序控制,所有操作在总按钮站上完成,方便可靠。
●具有自动冲屑、自动调刀、自动推料等功能
●占地面积小,地面安装方式,无需挖地坑或搭建站架,适用于自动化连线加工。
●适宜加工精度要求较高的中小工件。
Applications and Advantages
This vertical internal broaching machine is designed with single oil cylinder and lifting worktable. It can be used to broach the inner surface of holes with various shapes (e.g. round holes, internal splines and inner gears). The machine is suitable for large batch production with high production efficiency.
● stable workpiece and stepless speed regulation due to hydraulic drive.
● equipped with a safety device against over load
● 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.
● with functions of automatic chip flushing, automatic tool adjusting and automatic workpiece pushing.
● low space requirement, ground-level installation of the machine without a pit or pedestal, simple integration into automatic production lines.
● designed to machine small and medium-sized workpieces required higher accuracy.
