不采用跟刀架细长螺杆的加工

Long Slim Shaft Machining without Tail Bracket

一般工件长径比大于25(L/D>25)时称为细长轴。为防止工件受径向切削分力的作用而产生弯曲变形,常用中心架或跟刀架做辅助支撑,以增加工艺系统刚性。文中通过螺杆的工艺研究分析,在不使用跟刀架的情况下完成细长螺杆的加工。

We usually call it long slim shaft if the length is over 25 times to the diameter. In order to prevent the distortion of the work piece resulted from the radial cutting force, we often use center bracket or tail bracket as a additionally accessory to improve the rigidity of the process system. By discussing the machining process of the screw, we can realize machining long slim shaft without tail bracket.
