Profile: Thread Rolling Inc. is a process supplier of value-added roll threading, roll knurling, and centerless grinding services. Thread rolling is a cold forging process that can be performed on any ductile metal. The forming process can be used to produce other special forms, such as knurls. The process is performed on precision centerless ground blanks. The blank diameter of a rolled thread is at the pitch diameter, a theoretical point between the major diameter and minor diameter. Thread rolling is different from other types of threading processes like cutting, grinding, and chasing. We provide precision machined components & assemblies to aerospace, medical, and other high technology industries.
