Process: Thread Cutting


Thread cutting (threading) is a method to create helical patterns on a cylindrical or conical object to mate it with other parts. The friction is enough to prevent a rotational movement. Threaded components are also commonly used to convert a linear movement to rotation, or vice versa.

Probably, the most common threaded components are screws and nuts, but threads are found on many components. Most threads are manufactured according to metric or imperial standards. This is very practical since there is a variety of specifications to threads. Some of them are minor and major diameter, the thread's angle, the number of thread at start, length between threads, the number of threads when it is rotated 360 degrees, left or right- or left-handed threads and so on.

Most workshops can make threads. Threads can be made in thread rolling machines, which is suitable for high volumes and threads with a small diameter. Another way the thread is cut, which is done in lathes, milling machines or CNC centers, typically for small series or large diameters.

Two cutting tools are normally used for thread cutting; taps and dies. Dies creates external threads, and taps are for internal threads.

Cutting the external threads is known as threading or in some cases chasing, meanwhile cutting internal threads is called tapping.

    Machining-Thread Cutting

    This buyer - a manufacturer of sports cars, with an impressive annual spend of £500,000 on machining - seeks a supplier for the attached transmission stud. The component in question is to be made from S99G speciality steel and must be thread rolled - please note that a small amount of turning is also required. This is a redesign of an ongoing part and therefore, an order will be placed once old stock of the original design is depleted.
