Everyone knows that the screws, nuts, and bolts are very important implements in daily use in the industries as well as at home. There are innumerable uses of the screw in the industry. The screw may look like a very simple implement to all. However, a lot of effort goes into the making of the screws and the nuts. The most important part of the screws and the nuts is the thread. The pitch of the thread is an important factor as well. Therefore, the implements responsible for the formation of the threads such as the UN thread taps and dies have their importance as well.
The UN thread taps and thread dies come in various sizes and forms. You have to be very careful as well while using them. The beauty of these implements is that you can use them manually as well as mechanically. While using them with your hands, you should exercise the following precautions. Using the correct threading techniques is very important.
The taps are cutting tools. Therefore, it is imperative for them to be harder than the metal they have to thread. However, there is a disadvantage as well. The fact that they are very hard makes them brittle as well. They tend to break easily. Hence, you have to be careful while using these thread cutting tools. Using a T-handle to operate the taps would be a better idea instead of using the wrenches or pliers. The logic behind using the T-handle is very simple. You apply equal pressure from all sides. When you use the wrench, you apply an asymmetrical stress on the taps. This causes the ACME thread taps to break.
There would be tremendous friction when you use these taps and dies for carving out the threads. Therefore, you should ensure proper lubrication. This would also reduce the heat factor that could develop because of the friction. Lubricating the entire process would aid in the removal of the chips as well easily.
You have to be very careful not to break the tip of the tap. It would be a tough task to remove the broken part from the socket. This would be an expensive affair as well. Therefore, one should work slowly. You can take some more time. At least, you would not damage your equipment.
You should also be careful when you use the taps on the softer metals such as aluminum. Using the HSS taps and dies under these circumstances would be better. At the same time, the Cobalt taps work the best on the harder iron surfaces in the normal course. It would take some time for the grooves to form perfectly. You need to chip on for some time to view the results.
The taps would have the teeth and the flutes in alternate positions. While you chip away, the chipped pieces of metal can come in the way. The job of the flute is to clear the way for the teeth to progress further. You should avoid jamming of the metals during the job. Otherwise, you would risk breaking the tap.
