Tapping Technology
Tapping technology is a process used by industrial manufacturers to make threads on the outside of a piece of material. It is a process used to create threads in small spaces, where cumbersome thread-making machines won’t fit. Threads are cut into the material using a special tool, referred to as a tap. The type of tap used depends on the type of thread to be cut, with different taps labeled as metric or imperial.
In order to make tapered threads, a pointed tool is used, typically referred to as a bottoming tap. This style of tap is used most frequently for making hole threads due to the need for a deep throat. It is important to use the correct type of tap in order to form a successful thread.
When using a tap, the manufacturer may also need to use a cutting oil. This oil helps reduce friction and heat generated during the hole creation and tap descending processes. Heat can cause warping and breakage of the material, both of which must be avoided in order to ensure a successful thread formation. Without lubricating oil, it is more difficult for the tap to penetrate the material, making for more time-consuming, expensive work.
Tapping technology can be used to create either a straight-flute or cross-flute thread. Amongst other benefits, a cross-flute thread has a larger surface area, making it better able to withstand higher levels of shear forces. Additionally, cross-flute threads can run at faster speeds, making them the preferred choice where speed is an issue.
Once a thread has been created, it is important to monitor the threads on an ongoing basis. Depending on how frequently the threads are used, either hand-checking or machine-checking may be necessary in order to check their size and depth. Automated software can be used to check the threads for accuracy, as can CMM equipment.
The success of tapping technology very much depends on the materials being used. If a material is too hard, the tap will not be able to penetrate the material and create the thread. If a material has a low melting point, then the tap may cause it to melt, creating irregular threads.
It is possible to adjust the size and shape of a tap to help it penetrate different types of materials and stay within their tolerances. This includes making the tap thinner and sharper, as well as changing the flutes to create an optimal thread for the application.
In addition to mechanical and manual techniques, laser and electron beam machining can also be used to create threads. Laser machining is especially useful if tight tolerances are required. With laser machining, the control of the laser ensures that the threads are created with preciseness and accuracy.
When it comes to tapping technology, skill and experience are pivotal to successful thread formation. It is very important that the correct type of tap is used, as well as the right method of threading. With the right tools, the right materials, and the right experience, successful tapping technology can be achieved.
