FD-840双向型展刀头 

双滑块展刀是以曲柄为传动方式，进给速度稳定，便于进给速度与行程的调整。

The feeding mechanism of single slide broaching tool with counterweight balance slide block is rack and geartransmission mode, which is stable in feeding speed and convenient for adjusting feeding speed and stroke.

滑动面均经过硬化以及精密研磨，刚性与耐久性佳。

The sliding surfaces are hardened and precision ground, and have excellent rigidity and durability.

可与行控型回转油压缸搭配使用或搭配伺服马达以及滚珠丝杠机构做精密展刀加工，用于复杂轮廓、数控插补运动、车内外端面、内外沟槽、内外螺纹、直线镗孔、多台阶复合镗孔、倒角、锥度等。

lt can be used with line-controlled rotary hydraulic cylinder or with servo motor and ball screw mechanism for precisionbroaching, which is used for complex contour, numerical control interpolation movement, tuming inner and outer endfaces, inner and outer grooves, inner and outer threads, straight boring, multi-step compound boring, chamfering, taper,etc.

在拥有很大总刚性的同时，进行中到大难度的加工。

While possessing the maximum total rigidity, it can carry out moderate to difficult machining.

定义的装载式刀具的重量可以通过特定的配重平衡重量来平衡。

The weight of a defined loading tool can be balanced by a specific counterweight.

高转速，通过相对的滑块来实现平衡。

High rotating speed, balancing by opposite sliders.

极限转速和操作力取决于展刀头规格、刀具重量、刀具长度。

The limit speed and operating force depend on the specifications of the spreading head, the weight of the tool and thelength of the tool.
