The production of screw threads is one process that outnumbers any other form of machinery component production. Threading involves a range of techniques, including those that remove components (tapping and die-stamping) and those that add material (3D printing).
Engraving helical grooves into a workpiece creates what we call a “thread”. On the other hand, carving internal grooves is known as “tapping”, while cutting external grooves is termed “die-stamping”.
Three varieties of threading exist:
Thread cutting is a tremendously popular process, used to craft inimitable internal and external threads. To ensure the process is effective, specialist tools such as taps and dies are employed.
With rolling threading, large-diameter threads can be created. This calling requires the workpiece to be rolled between two threads, sculpted with customized forms.
Creating threads in delicate materials or those that are tough to work on can be accomplished by way of threading. This practice requires the employment of a specially-shaped die that is thrust into the workpiece in order to bring about the threads.
Producing threads can be completed on either a lathe or milling machine. The lathe is the most preferred machine for this task, yet this process can be executed with a milling machine if need be.
Differentiating Types of Taps
With its sharply pointed tip, the taper tap is ideal for drilling ever-so-slight pilot holes before creating the precise threads desired.
Taps with bottoming tips can be employed to craft a thread in an obstructed hole. Featuring a level tip, these taps are the perfect agent for achieving the desired result.
Here’s a look at the various forms of dies used today.
For threads with a pilot hole, the taper die provides the solution. With its curved tip, this die is perfectly capable of creating its own thread on the material surface.
Threads can be manufactured in blind holes with the help of bottoming dies, which feature a flat tip.
Threading is an essential machining process, with applications ranging from creating screw threads to engineering other objects. This process can be done in three distinct manners: cutting, rolling, and forming. It is typically carried out using either a lathe or a milling machine.
