The written title of customized double headed dental tap is called "double thread tapping". The three headed dental tap is naturally called "three thread tapping". The double headed or double thread here, in fact, refers to the direction of the tooth pattern. The customized double headed dental tap is mainly made into straight groove tapping or extrusion tapping. The number of spiral grooves is relatively small, and of course, it does not mean that they cannot be made, It's just that few customers will use it. For example, the medical metal structure is often customized with a double head dental tap. However, the utilization rate is very small. Only a few holes are used on the overall structure, and the holes punched by this customized thread are very short. To take a proportion, six holes can form a complete metal part, But how many sets can a special medical metal factory sell in a month? More tens of thousands of sets. To be honest, only a few silk taps are used. Another is the aerospace industry. But which base has you heard of building satellites all day long? The scope of use is very narrow. However, the advantages of customized double head thread taps are also very obvious. The precision is very high. Although the production difficulty is higher, it is not as high as that of the backlog tap. In fact, the production difficulty of double head straight groove tap is not high, but its service life and precision are similar to that of the traditional straight groove tap, Therefore, another kind of customized product of double head dental tap came into being, that is, double head dental tap. The service life and die precision of double head dental tap are very high, but at the same time, the cost is also very high, which is more than twice the distance. There is also three head dental tap, also called three thread dental tap. The precision of each adjacent dental tap is different, The tapping accuracy of triceps is obviously much higher than that of biceps. Of course, the cost is also high
