在机械加工中会经常遇到在盲孔中车削内螺纹的问题,为了防止刀具与孔底相撞,须及时退刀和提开和螺母(或开倒顺车)。此种方法比较麻烦,又不好操作。下面以在盲孔中车削几乎到底的右旋内螺纹为例,介绍反转车削螺纹的方法。1反转车削螺纹法的加工原理如图1所示,为了防止刀具碰底, In machining will often encounter the problem of turning the thread in the blind hole, in order to prevent the tool from colliding with the bottom of the hole, must be promptly retracted and opened and the nut (or open down the car). This method is too much trouble, not good operation. The following is an example of a right-handed female thread turning almost to the end in a blind hole to introduce a method of reversing a turning thread. 1 reverse turning thread machining principle shown in Figure 1, in order to prevent the tool touch the end,
