LKJ557系列数控机械拉床用途及特点：
本系列机床为本公司zhuan利产品，可广泛应用于各种形状内孔表面的拉削加工（如内花键、 内齿圈以及各种成型通槽），节能高效（无液压系统），性能稳定，适用于大批量生产。
●拉削中心与丝杆、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。
●机床采用双丝杆驱动，无液压油污染，在节能、噪音、维护保养成本方面得到大幅改善。
●电气系统采用西门子828D数控系统。
●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。
●具有旋转刷屑功能，使拉刀无残留铁屑。
●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:
As a patented product of our company, the type of machine can be widely used to broach the inner surface of holes with various shapes, such as internal splines, inner gears and other through grooves. It is applicable for mass production with features of low power-consumption, high efficiency and stable performance (no hydraulic system).
● 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.
● no hydraulic oil pollution, lower power-consumption, lower noise and lower cost risk in maintenance due to the use of twin screw drive.
● electrical system uses SIEMENS 828D CNC system
● 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.
