LKJ557系列數(shù)控機(jī)械拉床用途及特點：
本系列機(jī)床為本公司zhuan利產(chǎn)品，可廣泛應(yīng)用于各種形狀內(nèi)孔表面的拉削加工（如內(nèi)花鍵、 內(nèi)齒圈以及各種成型通槽），節(jié)能高效（無液壓系統(tǒng)），性能穩(wěn)定，適用于大批量生產(chǎn)。
●拉削中心與絲桿、導(dǎo)柱處于同一垂直面，工作臺無傾覆力矩，工作平穩(wěn)，拉削精度高。
●機(jī)床采用雙絲桿驅(qū)動，無液壓油污染，在節(jié)能、噪音、維護(hù)保養(yǎng)成本方面得到大幅改善。
●電氣系統(tǒng)采用西門子828D數(shù)控系統(tǒng)。
●占地面積小，地面式安裝，無需地坑或站架，與自動線實現(xiàn)無縫對接。
●具有自動沖屑、自動調(diào)刀、自動推料等功能。
●具有旋轉(zhuǎn)刷屑功能，使拉刀無殘留鐵屑。
●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:
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.
