Extrusion Tap

Extrusion tap is a new type of thread tool that uses the principle of metal plastic deformation to process internal threads. Extrusion taps are a chip-free machining process for internal threads. It is especially suitable for copper alloys and aluminum alloys with lower strength and better plasticity. It can also be used for tapping materials with low hardness and high plasticity, such as stainless steel and low carbon steel, with long life.
1. No chip processing. Because the extrusion tap is completed by cold extrusion, the workpiece is plastically deformed, especially in the blind hole processing, there is no problem of chipping, so there is no chip extrusion, and the tap is not easy to break.
2. Strengthen the strength of the tapped teeth. Extrusion taps will not damage the tissue fibers of the material to be processed, so the strength of the extruded thread is higher than that of the thread processed by the cutting tap.
3. Higher product qualification rate. Since extrusion taps are chip-free processing, the accuracy of the machined threads and the consistency of the taps are better than those of cutting taps, and cutting taps are completed by cutting. In the process of cutting iron chips, iron chips will always be more or less Exist, so that the pass rate will be lower.
4. The strength of the tap itself is good. Since the extrusion tap has no chip groove, its strength is much better than that of the cutting tap.
5. Longer service life, because the extrusion tap will not have problems such as dullness and chipping of the cutting edge, under normal circumstances, its service life is 3-20 times that of the cutting tap.
6. Higher production efficiency. It is precisely because of the longer service life and faster processing speed that the use of extrusion taps can reduce the time for tap replacement and standby.
7. No transitional thread. Extrusion taps can guide processing by themselves, which is more suitable for CNC processing, and it also makes it possible to process without transition teeth.
