Thread rolling is the process of manufacturing threaded parts by pressing and forming metal stock between two counter rotating threads. The process is widely used for producing high-precision and large-scale manufacturing parts of cylindrical, screw and curved shapes. Thread rolling is an ideal solution for producing large-scale repetitive parts since it is much faster and more precise than cutting or milling processes. Thread rolling produces high-quality, precise and consistent threads as well as long-lasting components, which makes it an ideal process for a variety of different applications.
Thread rolling, also known as roll forming, is a cold forming process that can be used to make threads on either rod-type parts or irregularly shaped parts. The two counter-rotating threads encase the metal stock and press and form the metal into the desired shape with a die. The high-pressure action of the counter-rotating dies compresses and shapes the metal as it passes through them. The material is then rolled through a set of dies in order to form the desired shape and thread.
The process of thread rolling is usually done on larger-scale components and involves machines to accurately roll the metal stock, as well as highly precise thread forming dies. In order to ensure accuracy and quality, thread rolling machines are designed with advanced features such as digital control, precision gearing, and computerized parameters. In addition, the use of specialized thread-forming tools can significantly improve the accuracy, efficiency, and quality of thread rolling processes.
Thread rolling is often used in many industries, such as the automotive, aerospace and medical industries. It is also used to produce a wide range of bolts and various other parts used in construction and maintenance, as well as military and aerospace applications. The most common types of thread rolling are standard-form rolling and cold-form rolling, but each process has its own specific set of applications and benefits.
Standard-form rolling is the most commonly used process and provides cost-effective production of large-scale parts. The process is often used for products such as screws, bolts and nuts. Standard-form rolling involves forming the metal stock into a desired shape and thread by press and roll forming. However, since the process relies on pressure and distortion of the material, there is a risk of creating inaccurate shapes and threads.
Cold-form rolling, on the other hand, does not rely on distortion of the material and is therefore much more precise. The process involves the use of a special tool to precisely form the thread into the exact shape and thread profile desired. Cold-form rolling is often used in aerospace, medical, and fastener applications, as the process provides superior accuracy and precision when forming the desired shape and thread profile. It is also used in the automotive industry in order to form threads of car parts, including gaskets, brake rotors, and other components.
Thread rolling is a highly versatile method of manufacturing and has many advantages over other processes. The process is relatively inexpensive, fast, accurate, and can produce high-quality parts with low scrap rates. It is also ideal for high-volume manufacturing, as the process can produce large numbers of parts with quick turnaround times. In addition, thread rolling can be used to produce parts of any size, shape, and thread profile, making it an ideal choice for a variety of applications.
