It can also be used for rolling spur gears, helical gears, and helical spline gears, as well as straightening, diameter reduction, burnishing, and various forming rolls. The thread rolling machine achieves thread rolling through the rotation of the rolling wheel and the movement of the feed mechanism. Compared with traditional cutting methods, it has higher efficiency, better surface quality, and longer service life.
