Automatic Thread Rolling Machine

Thread rolling machines are used to produce screws, bolts, and studs. Thread rolling is a cold-form forming operation used to form external screw threads in a blank. During the thread rolling process, a hard die is pressed onto a rotating workpiece (also called a blank) that is attached to the thread rolling machine.Rolled threads have improved physical characteristics, greater accuracy and a high degree of surface finish. They are uniformly produced at high rates of production with no wasting of material.A thread rolling screw (TRS) is a type of threaded fastener that utilizes threads to reliably and securely fasten different materials. These types of screws create threads in the material by forcing the material outward.
