At causes the threads produced by a die machine to be damaged?

Generally speaking, there are several main reasons why the threads produced by a die machine are damaged:
1. Poor quality of the steel pipe, such as an excessively large outer diameter of the workpiece material in the threading area.
2. The workpiece overheats during threading without timely cooling.
3. The speed of the die machine is set too high.
4. The workpiece does not rotate around its axis center.
5. Poor craftsmanship of the dies.
6. Improper operation method of the die machine.
Some friends also ask, why are the threads produced by the die machine crooked? Die machine manufacturers will tell you that this can only indicate that there is a problem with the chuck. An unaligned chuck leads to this situation.
