2017年9月14日 · Thread rolling improves metal tensile strength by 30% or more compared to traditional cutting methods, and, due to the hardening phenomenon the material undergoes during the rolling process, increases fatigue strength by 50-75%. The geometry of the roller dies allows for a highly accurate thread form, and the intense pressure applied allows for ...

Thread rolling is the preferred method for achieving these objectives. Outsourced thread rolling processes are more efficient and simply better than producing threads by cutting or grinding, especially on parts made from difficult metals. In this “How It Works” note, we explain the thread rolling process, its advantages, and how

Thread rolling is the preferred method for producing strong, smooth, precise, and uniform external thread forms. Outsourced thread rolling processes are often more efficient than producing threads by cutting or grinding, especially on parts made from difficult metals.

2020年5月4日 · Thread rolling is a metal forging process that forms threads into the mirror image of a roller die. The process is different from metal cutting, grinding, and chasing because it does not remove any metal from the workpiece. Instead, thread rolling uses hardened steel dies to displace and mold ductile metals.

2016年9月7日 · In the thread rolling process, part revolutions directly relate to thread roll penetration. A method of penetration rate control, as it relates to part revolutions, is the control valve assembly — adjusting the flow control valve on the assembly’s “out” line will adjust penetration rate and part revolutions.

2020年4月19日 · Additionally, a piece can occasionally harden before the thread rolling process is complete. Caused by the tool becoming dull, avoid running into these work hardening issues by simply increasing the rate of penetration when rolling the thread. Thread Rolling Problems: Hollow Work, Closed Hole, or Out of Round Conditions
