3HP Automatic Cold Thread Rolling Machine

Thread rolling is a cold working process where a machined blank is compressed between rotating or reciprocating dies, whose thread profile is ground into the dies. As the blank cylinder is penetrated by the dies, the metal flows into the die cavities and forms the thread profile into the part.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.A rolling machine is a piece of manufacturing equipment that contains two or more rollers through which raw metal is fed. The purpose of rolling machines is to compress raw metal into a thinner and more uniform shape, which is essential when producing sheet metal.
