How to solve the bending problem of trapezoidal screw

Firstly, determine the bending position of the trapezoidal screw, whether it is a local or overall bending, or a small or large amount of bending, before deciding whether to use manual straightening or use a press to straighten the trapezoidal screw.

Secondly, when straightening the trapezoidal screw, there is basically no need to use any machine tool to provide auxiliary support surfaces, because using a lathe to straighten the trapezoidal screw often fails to achieve the desired effect. This is mainly because the machine tool mainly uses flames or impacts during straightening, which will inevitably have an impact on the trapezoidal screw, Mainly, this method will cause serious centrifugal force when the trapezoidal screw rotates.

Once again: If the trapezoidal lead screw shows overall bending, use a press to straighten it. Place the trapezoidal lead screw directly on the shaped iron, and place the pre prepared circular mold on the surface of the trapezoidal lead screw. Then, the straightening effect can be observed with the naked eye.

Finally, when the bending of the trapezoidal screw is localized, a good straightening method is manual straightening, which is the same as overall straightening. Manual straightening uses a sledgehammer to repeatedly strike the bending position of the screw to achieve the desired straightening effect.
