SFA-2015伺服内置式展刀头

带配重平衡滑块的单滑块展刀，进给机构是齿轮与滚珠丝杠的传动方式，进给速度稳定，便于进给速度与行程的调整。

The feeding mechanism of the single slider broaching tool with counterweight balancing slider is the transmission modeof gear and ball screw, which is stable in feeding speed and convenient for adjustment of 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.

展刀头内置行星减速机、伺服电机驱动，减少机械传动累计误差。

Planetary reducer and servo motor drive are built in the spreading tool bit to reduce the accumulated error of mechanicaltransmission.

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。

Used for complex contour, numerical control interpolation movement, turning inner and outer end faces, inner and outergrooves, inner and outer threads, straight boring, multi-step compound boring, chamfering, taper, etc.

电源及编码器出线需配置滑环使用。

Power supply and encoder outlet shall be equipped with slip ring.

展刀皆为背隙可消除式。

The broaches are all backgap-eliminating.

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、刀具长度以及滑块位置。

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