Semi 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.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.In the rolling process, stock of material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process mainly focused on the cross-section of the ingot or metal to be pressed which aid the reduction of the workpiece thickness.
