The trapezoidal thread taps are special

    You need different types of threads for different machines. There are numerous types of threads available such as the metric threads, ACME threads, trapezoidal threads, the UNC, UNF, UNEF threads, metric threads, Whitworth threads, and so on. You require different kinds of thread taps to carve out these threads as well. We had seen some of the types of thread tap in one of our previous blogs. We shall now look at some more thread taps such as the trapezoidal thread taps, UN thread taps and so on.

    • The thread forming tap: These taps are also known as fluteless taps. However, they have one or more lubrication grooves. It has a lobed thread form thereby ensuring there are finite numbers of points contacting the work. The best aspect of these fluteless taps is that they do not cut. Hence, it will not cause a chip problem. These fluteless taps form the threads by extrusion. This ensures that the thread size is constantly maintained. You get threads of better quality and faster tapping speeds. At the same time, you have higher production with these taps not generating any chips. You end up with a higher production as you can carve out the threads until the very ends of the hole.
    • Pipe taps: Pipes are special equipment that has internal as well as external threads depending on the usage. There are different types of pipe taps such as the straight pipe taps and the taper pipe taps. You have the NPT thread taps as well.   
    • Combined drill and tap: Until now, we had seen only taps that thread in a hole already drilled for the purpose. The combined drill and tap simplifies various operations as it drills the holes while carving out the threads at the same time. This is a value addition to the tool as you can do multiple jobs with one operation.
    • ACME thread tap: The ACME threads have great use in heavy duty equipment like jacks, valves, presses, and other machinery. You need strong threads to be able to manage these heavy loads. The ACME thread with an angle of 29 degrees is well equipped to handle these loads. You need ACME thread taps to carve out these ACME threads.
    • Trapezoidal thread taps: The trapezoidal threads are similar to the ACME threads in almost all ways except for the fact that the trapezoidal threads are at an angle of 30 degrees when compared to the ACME threads at 29 degrees. You need specially engineered trapezoidal thread taps because of the severity of the cuts required to produce trapezoidal threads. The trapezoidal threads have great use in heavy-duty equipment like the lead screws in case of lathe machines and aircraft doors, etc.  

     

    We have seen some more thread taps in this blog. There are many more that we shall discuss in our subsequent blog. Thread taps have great importance in the manufacturing industry. These thread taps require continuous lubrication while they work because of the extreme heat they generate while chipping away the metal while carving out the threads.
