Tungsten Carbide End Mill’s Advantages in Thread Machining

Tungsten carbide end mill is a kind of cutting tool used in thread machining. It was firstly popular in occident, and later, with the development of numerically-controlled machine tools in China, it is also gradually accepted by users in China.

The traditional method for thread machining is normally done by using thread turning tools or screw taps, but now the numerically-controlled machining technology has made it possible to do thread machining with more advanced method, i.e. numerical control milling. Compared with traditional method of thread machining, tungsten carbide end mill machining is of greater advantages in machining precision, machining efficiency, etc. In addition, it is free from the limitation of thread structure and the direction of turning, and thus can be used in the threading of the internal and external threads of different kinds of turning directions.

For those threads that allow no tool withdrawal grooves, it is difficult to do machining with traditional turning method, like using screw taps or threading dies, but easy with numerical control milling. What is more, the duration of tungsten carbide end mill is over ten times larger than screw taps. Also, it is quite convenient to do adjustment towards tread diameter size if an end mill is used in the numerical control milling.
