What is the largest diameter screw that the thread rolling machine can produce

The  automatic thread rolling machine is a multifunctional cold extrusion forming machine tool. The thread rolling machine can perform thread, straight, and twill rolling treatments on the workpiece in the cold state within its rolling pressure range; straight, helical and oblique spline gears Rolling; thread rolling machine straightening, reducing diameter, rolling and various forming rolling. The machine has a safe and reliable electric-hydraulic execution and control system, which allows each working cycle to be selected from manual, semi-automatic and automatic modes. The thread rolling cold rolling process is an advanced non-cutting processing, which can effectively improve the internal and surface quality of the workpiece. The radial compressive stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece, which is a highly efficient , An ideal process for energy saving and low consumption.
