Thread rolling is known as a cold metal forging process performed on ductile metals. Thread rollers often have to decide between two threading options for creating screw threads - thread rolling and thread cutting.
Each with its unique characteristics and capabilities, both threading processes are credited for creating the highest produced machine element every year.
Thread rolling is different than cutting, grinding, and chasing in that it does not remove any metal, but instead uses steel dies to displace and mold the metals.
