Factors Affecting Bending Accuracy Of Bending Tube Machining

In the process of bending the material will be subjected to its lateral and inner pressure position is different from the method of bending the contraction zigzag, in the operation of the middle axis is about 1/3 from the outer wall, bending back neutral axis is 2/3 from the outer wall, so the thin wall zigzag is often favorable.
