1.How Does the Thread Rolling Process Work?

We attach importance to the innovation ability and team spirit of employees, have advanced R & D facilities and laboratories, and have a good quality management system.
The thread rolling process is a cold forming process used to create external threads on a workpiece. It involves pressing a hardened steel die onto the surface of the workpiece, causing the material to flow and form the desired thread shape.

The process begins with a blank workpiece, typically a cylindrical rod or bar, which is fed into the thread rolling machine. The machine consists of two dies, an upper and a lower die, which are mounted on parallel spindles and rotate in opposite directions.

The upper die is stationary, while the lower die is adjustable and can be moved up and down to accommodate different thread sizes. The dies are also equipped with thread profiles that correspond to the desired thread shape.

As the workpiece is fed between the two dies, it is gripped and held in place by a set of rollers. The rollers apply pressure to the workpiece, forcing it to deform and flow into the thread profile of the dies.

The dies then rotate, causing the material to be displaced and formed into the desired thread shape. The pressure and rotation of the dies continue until the thread is fully formed.

Once the thread is formed, the dies retract, and the workpiece is released. The thread is then checked for accuracy using gauges and other measuring tools.

The thread rolling process is highly efficient and can produce threads at a much faster rate than traditional cutting methods. It also results in a stronger and more precise thread, making it a preferred method for creating high-quality threads in mass production.

We have the leading technology and innovation capabilities, and attach importance to employee training and development, and provide promotion opportunities.
Thread rolling and thread cutting are two different methods used to create threads on a workpiece. The main difference between them lies in the way the threads are formed.

Thread rolling is a cold forming process in which a hardened steel die is pressed against the surface of a rotating workpiece. The pressure from the die creates the threads on the workpiece by displacing the material. This process is typically used for creating external threads on cylindrical parts, such as bolts, screws, and studs. It is a highly efficient and precise method that produces strong and accurate threads.

On the other hand, thread cutting is a machining process in which a cutting tool is used to remove material from the workpiece to create threads. The cutting tool is usually a tap or a die, and it is rotated or moved along the workpiece to cut the threads. This process is commonly used for creating internal threads on holes or external threads on shafts. It is a slower process compared to thread rolling, but it allows for more flexibility in terms of thread size and shape. In summary, thread rolling is a cold forming process that uses pressure to create threads, while thread cutting is a machining process that uses cutting tools to remove material and create threads. Both methods have their advantages and are used in different applications depending on the requirements.
