When straightening, it is not necessary to use the machine tool to carry out the auxiliary support surface, because in most cases, the straightening effect cannot be achieved by using the lathe. The main reason is that the machine tool basically uses flame or impact when straightening, which will affect the screw rod. The main reason is that this method will cause serious centrifugal force when rotating.


If the lead screw is bent as a whole, try to use a press to straighten it, directly place it on the molding iron, put the prepared mould with a round shape, and then observe the straightening effect with the naked eye.
