我们过去加工圆锥管螺纹是采取正车挑扣的方法。这样操作难度大,吃刀深度不易掌握均匀,容易产生啃刀或者将锥螺纹车成阶梯螺纹或圆柱螺纹。其主要原因是由于横向丝杠反时针旋转时的间隙方向,与切削时的径向抗力方向形成了顺向。为了将这个顺向改变为逆向,我们把正车挑扣改为反车挑扣,如图示,这样就可改变切削时的径向抗力方向,使操作方 We used to process the taper pipe threads to take the wrong approach. This operation is very difficult, not easy to grasp the depth of the knife to grasp uniform, prone to eating knives or taper thread into a ladder thread or cylindrical thread. The main reason is that the direction of the clearance when the horizontal screw rotates counterclockwise forms a forward direction with the direction of radial resistance during cutting. In order to change this forward to reverse, we pick the positive car buckle to anti-car buckle buckle, as shown, so you can change the cutting radial resistance direction, so that the operator
